The Ultimate WordPress Technical SEO Guide (2026): Everything Google Actually Cares About

Most WordPress SEO guides stop at “install a plugin and add a sitemap.” This one doesn’t.

This guide covers the full technical architecture stack — crawl governance, indexing control, Core Web Vitals optimization, schema markup, server-level fixes, and the AI-era signals reshaping rankings in 2026. And throughout, we’ll show you exactly how SkySEOManager handles each layer so you’re not juggling five different tools.

Let’s get into it.

Why Technical SEO Is the Highest-Leverage Work You Can Do in WordPress

Here’s an uncomfortable truth: you can write the best article on a topic and still lose to a technically superior site with mediocre content.

In 2026, Google is no longer just a text-matching engine. It crawls with Googlebot, renders JavaScript, assesses page experience signals, measures Core Web Vitals in real time, and uses AI models to understand relationships between content types. A site with broken technical infrastructure is invisible — regardless of how good the content is.

WordPress powers 43% of all websites on the internet. But that ubiquity comes with a hidden tax: WordPress out of the box is not optimized for technical SEO. Its default URL structure exposes duplicate archives, tag pages, author pages, and category overlaps that silently bleed crawl budget. Its default image handling is passive. Its plugin ecosystem is a minefield of render-blocking scripts.

This guide fixes all of that — systematically.

1. How Google Actually Processes Your WordPress Site

Before you touch a single setting, understand what happens when Googlebot visits your site. The crawl-render-index pipeline works like this:

Googlebot discovers URL
        ↓
Checks robots.txt — can it crawl this?
        ↓
Fetches HTML from your server
        ↓
Renders JavaScript (Chrome-based renderer)
        ↓
Evaluates indexability signals (canonical, noindex, meta robots)
        ↓
Assesses page experience (Core Web Vitals, HTTPS, mobile)
        ↓
Extracts entities, links, structured data
        ↓
Decides to index and assigns quality signals

Most WordPress site owners only think about steps 5–8. Steps 1–4 are where most sites bleed authority, crawl budget, and rankings silently.

The 2026 shift: Google’s crawler now uses its Multitask Unified Model (MUM) to understand relationships between content types — meaning your content’s semantic completeness matters as much as its technical accessibility. A technically perfect page with thin content still doesn’t win.

---

2. Crawl Architecture: The Most Underrated WordPress SEO Problem

What Is Crawl Budget — and When Does It Actually Matter?

Crawl budget is the number of pages Googlebot will crawl on your site within a given time period. For small sites under ~500 pages, it’s rarely a limiting factor. For larger sites — e-commerce stores, membership sites, publication archives — it becomes critical.

Google calculates crawl budget based on two signals: how fast your server can handle Googlebot without degrading user experience, and how popular and fresh your pages appear to be.

The problem: WordPress generates enormous amounts of low-value URLs by default. Every tag, category, author archive, pagination variant, and date archive is a separate URL Googlebot can — and will — crawl. If your site has 200 real pages but 1,400 discoverable URLs because of WordPress’s default behavior, Googlebot may never reach your most important content.

WordPress URL Bloat: The Hidden Crawl Tax

A typical WordPress site generates these URL types you probably didn’t intentionally create:

URL Type	Example	SEO Value
Tag archives	/tag/wordpress-seo/	Low (usually thin)
Author archives	/author/admin/	Low (duplicate content risk)
Date archives	/2023/04/15/	Near zero
Pagination variants	/page/2/, /page/3/	Contextual
Search result pages	/?s=keyword	Zero — infinite, must be noindexed
Feed URLs	/feed/, /comments/feed/	Near zero
Attachment pages	/wp-content/uploads/...	Zero

How to audit crawl waste: Use Screaming Frog to crawl your site and export all discoverable URLs. If the total is more than 3× your intentional page count, you have a crawl waste problem. Cross-reference with Google Search Console’s Coverage report — if it shows thousands of “Discovered — currently not indexed” URLs, that’s diagnostic gold pointing directly to your crawl waste problem.

---

3. Robots.txt: Stop Wasting Google’s Time

WordPress’s default robots.txt does one thing: it blocks /wp-admin/. Everything else is wide open — which means Googlebot is happily crawling your search result pages, attachment pages, admin AJAX endpoints, and feed duplications.

Managing Robots.txt with SkySEOManager

SkySEOManager includes a dedicated Robots.txt Manager tab with two synchronized editing modes:

• Visual rule builder — Add Allow, Disallow, or Sitemap directives without touching code. You select the directive type, enter the path, and it’s added instantly.
• Raw code editor — Synced in real time with the visual builder. Switch between modes at any point; changes in one immediately reflect in the other.

The standout feature: click “AI Analyze” and Gemini reviews your entire robots.txt file against modern SEO best practices, flagging risky rules and suggesting improvements. This turns what was previously a job for a technical SEO consultant into a two-minute task.

A Production-Ready WordPress Robots.txt

Here’s a solid starting point you can paste into SkySEOManager’s raw editor:

User-agent: *

# WordPress system areas
Disallow: /wp-admin/
Disallow: /wp-login.php
Disallow: /wp-content/plugins/
Disallow: /wp-content/themes/
Disallow: /wp-includes/

# Infinite/zero-value URL spaces
Disallow: /?s=
Disallow: /search/
Disallow: /feed/
Disallow: /*/feed/
Disallow: /*/trackback/
Disallow: /trackback/

# Thin archive pages (evaluate per site)
Disallow: /author/
Disallow: /date/

# Allow CSS/JS so Googlebot can render your pages
Allow: /wp-content/themes/*.css
Allow: /wp-content/themes/*.js
Allow: /wp-content/plugins/*.css
Allow: /wp-content/plugins/*.js

Sitemap: https://yoursite.com/sitemap.xml

# AI crawler governance (2026)
User-agent: GPTBot
Disallow: /

User-agent: anthropic-ai
Disallow: /

User-agent: CCBot
Disallow: /

Critical distinction: Blocking a URL in robots.txt does NOT prevent it from being indexed if it’s linked from external pages. Google can still list a blocked page in SERPs based on external signals. Robots.txt governs crawling — it does not control indexing. For actual de-indexing, use noindex on crawlable pages. Never combine blocking in robots.txt AND noindex on the same URL.

The 2026 AI Crawler Consideration

AI crawlers (GPTBot, anthropic-ai, CCBot, PerplexityBot) now consume significant server resources. Whether to allow or block them depends on your strategy. If you want AI-generated summaries to reference your content — a strategy called Answer Engine Optimization (AEO) — allow them. If you’re concerned about content scraping without attribution, block them. Run SkySEOManager’s AI Analyze feature to think through the tradeoffs for your specific setup.

4. XML Sitemaps Done Right

Your sitemap is your direct communication channel to Google about what matters on your site. Auto-generating one is a start — but most sites do it wrong.

SkySEOManager’s Sitemap Tab

Navigate to SkySEOManager → Sitemap to:

1. Enable sitemap generation with one toggle
2. Select exactly which public post types to include — posts, pages, products, custom post types
3. Access your sitemap immediately at /sitemap.xml

If your site uses TranslatePress for multilingual content, SkySEOManager automatically creates language-specific sitemap variants for each selected post type — a significant technical lift handled automatically.

What to Exclude from Your Sitemap

A clean sitemap tells Google what matters. Including everything dilutes the signal.

Exclude:

• Tag archive pages (unless they’re content-rich editorial hubs)
• Author archives
• Date-based archives
• Paginated versions beyond page 1
• Thank-you pages, login pages, account pages
• Any URL you’ve marked noindex

The cardinal sin: Including noindex URLs in your sitemap. This sends Google contradictory signals — include this, but also ignore it. Use SkySEOManager’s Indexing & SEO Box tab to set default noindex rules per post type, then keep those types out of your sitemap settings.

Monitoring Your Sitemap in Google Search Console

After submitting via GSC → Sitemaps, watch for these errors monthly:

• “Submitted URL not found (404)” — your sitemap references deleted or moved content
• “Submitted URL blocked by robots.txt” — contradiction between sitemap and robots.txt
• “Submitted URL marked ‘noindex'” — another contradiction to resolve immediately

These errors silently waste crawl budget. They’re common after site migrations, content cleanups, or permalink changes.

---

5. Indexing Control: Canonicals, Noindex, and Crawl Sculpting

This is where most WordPress sites bleed rankings without realizing it.

Canonical Tags: The Most Misunderstood Technical SEO Tool

A canonical tag tells Google: “Of all the versions of this content, this is the one I want indexed.” WordPress creates canonical challenges in several ways that catch most site owners off-guard.

Category + Tag URL overlap. A post at /blog/my-post/ may also be accessible via /category/seo/my-post/ and /tag/wordpress/my-post/. All three URLs need to canonicalize to the primary URL.

HTTP vs HTTPS, www vs non-www. If your site is accessible at four URL variants, you need both canonicals AND 301 redirects to consolidate them — not just one or the other.

Canonical chains. A canonical pointing to a URL that itself has a canonical. Google stops following the chain and ignores your directive. Audit for chains whenever you migrate content.

Canonical checklist:

• Every page has exactly one canonical tag
• Canonical points to the HTTPS, consistently formatted (www or non-www) version
• Canonical URL is included in your sitemap
• No canonical chains anywhere on the site
• Paginated pages self-canonicalize or use correct pagination logic

Noindex with SkySEOManager

SkySEOManager’s Indexing & SEO Box tab lets you set default noindex or nofollow rules for entire post types and taxonomies — in bulk, without editing individual posts. This is the right approach for handling thin archives at scale.

What to noindex by default:

• Tag archives with fewer than 5 quality posts
• Author archives on single-author sites
• Date-based archives
• WordPress search pages (/?s=)
• Thank-you and confirmation pages

What requires case-by-case judgment:

• Category pages — index if they have editorial intro content, noindex if they’re pure link lists
• Paginated archives — index pages 2–3+ if they drive measurable traffic, noindex if they don’t

For individual posts or pages, use the SkySEOManager SEO Box inside the Gutenberg editor → Advanced tab for per-item noindex and nofollow controls. Full granularity without code.

The Noindex Trap

Never block a page in robots.txt AND mark it noindex. If Googlebot can’t crawl a page, it can’t read the noindex directive — so the page may still appear in SERPs via external link signals. The rule: use robots.txt to block system-level paths (admin, plugin assets, theme files), and use noindex for content pages you want crawled but not indexed.

---

6. URL Structure and Permalink Optimization

URL structure affects crawlability, user experience, and click-through rates. WordPress gives you full control — which is both an advantage and a responsibility.

The Right Permalink Setting

Go to Settings → Permalinks and choose Post name: /%postname%/

Avoid date-based structures (/%year%/%monthnum%/%postname%/) unless you’re running a news publication. Date-based URLs signal content age to users and hurt CTR for evergreen content — readers see “2021” in a URL and immediately question whether the information is still accurate.

URL best practices:

• Keep URLs short and descriptive: 3–5 meaningful words
• Use hyphens, not underscores (Google treats hyphens as word separators)
• Drop stop words (a, the, and, of) from URLs
• Never change a URL after it’s been indexed without a 301 redirect

Category Prefixes: Remove Them

WordPress adds /category/ to all category URLs by default, so your SEO category lives at /category/seo/ instead of /seo/. This adds unnecessary depth to your URL hierarchy. Remove the prefix with a dedicated rewrite plugin — but set up 301 redirects from old category URLs before making the change.

Trailing Slashes: Commit to One Format

Pick a format — with trailing slash (/my-page/) or without (/my-page) — and enforce it sitewide via .htaccess or Nginx configuration. Mixed usage creates technical duplicate content that splits crawl signals between two versions of the same page.

---

7. Core Web Vitals: LCP, INP, and CLS for WordPress

Core Web Vitals are Google’s quantified user experience signals and a direct ranking factor. In 2026, three metrics define page experience.

Largest Contentful Paint (LCP) — Target: Under 2.5 Seconds

LCP measures how long it takes for the largest visible content element — usually a hero image or main headline — to render on screen.

Top WordPress LCP killers and their fixes:

Cause	Fix
Unoptimized hero image	Convert to WebP; add fetchpriority="high"
Slow server response	Upgrade to managed WordPress hosting or a VPS
Render-blocking scripts above the fold	Defer non-critical JS; inline critical CSS
No page caching	Enable server-level page caching
No CDN	Add Cloudflare or BunnyCDN
Google Fonts loading remotely	Self-host your fonts

The most impactful single change: serve your hero image with fetchpriority="high" to tell the browser to load it before anything else:

html

%lt;img 
  src="hero-image.webp" 
  alt="Descriptive alt text" 
  fetchpriority="high"
  loading="eager"
  width="1200" 
  height="630"
>

Interaction to Next Paint (INP) — Target: Under 200ms

INP replaced FID (First Input Delay) in March 2024. Unlike FID, which only measured your first interaction, INP measures responsiveness throughout the entire user session — every click, tap, and keyboard input during the visit.

WordPress INP killers:

• Heavy JavaScript from page builders (Elementor, WPBakery, Divi)
• Analytics scripts blocking the main thread during page load
• Cookie consent scripts with synchronous initialization
• Poorly coded plugins running excessive jQuery on every page

Fixing INP: Use Chrome DevTools → Performance tab to identify long tasks (anything over 50ms on the main thread). Defer third-party scripts until after user interaction. Audit plugins with Query Monitor to find the JavaScript-heavy offenders that are causing main thread congestion.

Cumulative Layout Shift (CLS) — Target: Under 0.1

CLS measures how much your page unexpectedly shifts during loading — the frustrating experience of clicking a button that jumps away as an image loads above it.

WordPress CLS culprits:

• Images without explicit width and height attributes (browser can’t reserve space)
• Ads loading without a reserved container
• Web fonts causing text reflow while loading
• Cookie banners appearing above existing content

Quick fix for missing image dimensions (add to functions.php):

php

function add_image_dimensions($attr, $attachment, $size) {
    if (empty($attr['width']) || empty($attr['height'])) {
        $meta = wp_get_attachment_metadata($attachment->ID);
        if ($meta && isset($meta['width'], $meta['height'])) {
            $attr['width'] = $meta['width'];
            $attr['height'] = $meta['height'];
        }
    }
    return $attr;
}
add_filter('wp_get_attachment_image_attributes', 'add_image_dimensions', 10, 3);

Measuring Core Web Vitals Correctly

There are two types of data — and only one is what Google uses for ranking:

Field data (real user measurements — what Google actually ranks on):

• Google Search Console → Core Web Vitals report
• PageSpeed Insights → Field Data section (labeled “Discover what your real users experience”)

Lab data (simulated — useful for diagnosing problems, not for ranking):

• Lighthouse in Chrome DevTools
• GTmetrix
• WebPageTest

Always optimize for field data. A perfect Lighthouse score on a slow server with slow real users is a vanity metric, not a ranking signal.

8. HTTPS, Redirects, and the 404 Problem

HTTPS: The Non-Negotiable Foundation

If your site is still on HTTP in 2026, no technical optimization in this guide will help you. Get an SSL certificate — Let’s Encrypt is free — and force HTTPS.

WordPress HTTPS migration checklist:

• SSL certificate installed on your server
• WordPress Address and Site Address updated to HTTPS in Settings → General
• 301 redirects from HTTP to HTTPS configured at the server level
• All internal links updated to HTTPS (use a database Search & Replace tool)
• Google Search Console updated to track the HTTPS property separately
• Mixed content warnings resolved (HTTP resources loading on HTTPS pages)

Redirect Architecture

Poor redirect management is a crawl budget killer. Every redirect passes PageRank — but redirect chains lose signal at each hop as Googlebot follows them.

The rules:

• 301 for permanent moves (preserves ~99% of link equity)
• 302 for temporary redirects (preserves equity with the original URL)
• Never chain redirects — consolidate A→B→C to A→C
• Audit your redirect stack annually — old rules accumulate and slow server responses

404 Monitor: Where SkySEOManager Becomes Essential

Broken links are silent SEO killers. Every 404 your visitors hit is a dead end for users and a wasted crawl opportunity for Googlebot. Most WordPress site owners only discover broken links during a full audit — by which point hundreds of them have accumulated.

SkySEOManager’s 404 Monitor automatically logs every 404 error on your site with:

• The broken URL
• Hit count — how many times it’s been triggered
• First seen / last seen timestamps
• Referrer — where the traffic is coming from

From the monitor dashboard, you can create 301 or 302 redirects directly to the right destination with no .htaccess editing required. The AI 404 Redirect Suggest feature uses Gemini to automatically recommend the best redirect target for each broken URL based on your existing content — turning a multi-hour cleanup task into minutes.

404 Email Alerts (configure via SkySEOManager → 404 Settings):

• Choose frequency: immediate, hourly, or daily digest
• Set a minimum hit threshold so you’re not alerted for every bot probe
• Configure SMTP settings for reliable delivery
• Use the test email button before relying on it

Entries older than 90 days without an active redirect are automatically purged from the database — no manual cleanup required.

9. Schema Markup: Beyond the Basics

Schema markup is how you communicate entity relationships to Google in a machine-readable language. In 2026, with AI summaries increasingly dominating above-the-fold SERP real estate, schema has moved from optional to foundational.

Schema Types That SkySEOManager Handles Automatically

Article / BlogPosting Every blog post gets Article or BlogPosting schema automatically, with datePublished and dateModified accurately populated.

Organization Configure Organization schema for your homepage via SkySEOManager → Settings. Include your company name, logo URL, and social media profile links. This builds entity authority — Google’s way of recognizing your brand as a known entity in its Knowledge Graph rather than just a domain name.

BreadcrumbList SkySEOManager generates BreadcrumbList schema sitewide. Enable it with your preferred separator, home label, and display options. Breadcrumb rich results appear directly in the SERP below your title and improve CTR.

Homepage Schema Types Choose between Organization, Person, LocalBusiness, or WebSite schema for your homepage — depending on whether you’re representing a company, individual, local business, or content publication.

WooCommerce / Product Schema Full automatic Product schema for WooCommerce products, including price, availability, and product images in sitemaps. No extra configuration beyond your WooCommerce setup.

Gutenberg Blocks for Rich Snippet Schema — SkySEOManager’s Differentiator

Most SEO tools make you hand-code JSON-LD or navigate a separate settings panel after writing your content. SkySEOManager provides native Gutenberg blocks that generate valid schema as part of your editing workflow:

Sky SEO FAQ Block Add the FAQ block to any post, fill in your questions and answers directly in the block editor, and valid FAQ schema is generated on publish. FAQ rich results can dramatically expand your SERP footprint — showing expandable Q&A directly beneath your result, often pushing competitors further down the page.

Sky SEO How-To Block For tutorial and guide content, add the How-To block and fill in your steps interactively. Valid HowTo schema is generated automatically, eligible for rich step-by-step results in Google Search.

Sky SEO Review Block Add product review schema to review posts or comparison content using the interactive rating fields in the block — no JSON required.

The workflow improvement here is real: you build the content and the schema simultaneously, in the same editing environment, without switching context or copying markup between tools.

Testing Your Schema

Validate after every implementation:

1. Google Rich Results Test: search.google.com/test/rich-results
2. Schema.org Validator: validator.schema.org
3. Google Search Console → Search Appearance → Rich Results (check after 2–4 weeks of indexing)

Common mistake: author schema without sameAs links. Your author schema should link to the author’s professional profiles — LinkedIn, Twitter/X, personal site. This is a concrete E-E-A-T (Experience, Expertise, Authoritativeness, Trust) signal that Google’s quality raters specifically look for in 2026.

---

10. International SEO and Multilingual WordPress

If your site serves multiple languages or regions, hreflang tags tell Google which version to show to which user. Getting this wrong means UK visitors land on US-localized content and immediately bounce — destroying both CTR and session quality signals.

Multilingual Sitemaps with SkySEOManager

When TranslatePress is active on your site, SkySEOManager automatically creates language-specific sitemap variants for each selected post type. This handles one of the most technically complex aspects of multilingual WordPress SEO without requiring separate configuration — the plugin detects TranslatePress and extends the sitemap behavior accordingly.

The Hreflang Reciprocity Rule

Every hreflang implementation must be reciprocal. If page A lists page B as its German equivalent, page B must list page A as its English equivalent. Broken reciprocity causes Google to ignore your hreflang tags entirely — a silent failure that’s hard to diagnose without a dedicated audit tool.

Implementation options:

• Subfolder structure (/en/, /de/) — manageable with plugins and hreflang injection via header
• Subdomain structure (de.example.com) — stronger separation, more complex to manage
• Separate domains (example.de, example.co.uk) — strongest geo-targeting signal, requires separate GSC properties with hreflang cross-linking between them

Use Aleyda Solis’s free hreflang validator to audit reciprocity across your multilingual pages before assuming the implementation is working correctly.

11. WordPress Technical Debt You’re Probably Ignoring

Plugin Bloat: The Silent Performance Killer

Every plugin adds JavaScript execution time, database queries, PHP processing overhead, and CSS to your stack. In practice, WordPress sites accumulate redundant functionality over time as teams change, needs evolve, and old experiments are never cleaned up.

Plugin audit process:

1. Install Query Monitor and check database query load per plugin
2. Deactivate plugins one by one and measure TTFB before and after each
3. Look for duplication — two plugins doing the same job, badly, together
4. Remove deactivated plugins from the filesystem entirely

Database Optimization

WordPress’s database accumulates garbage over time: post revisions, spam comments, orphaned metadata, expired transients. This bloats database size and slows every page-generating query.

Clean regularly with WP-Optimize. Limit post revisions proactively in wp-config.php:

php

define('WP_POST_REVISIONS', 5);

Image Optimization: The Full Stack

Layer	Action
Format	Convert to WebP — 60–80% smaller than JPEG at equivalent quality
Dimensions	Resize before uploading — don’t rely on CSS to shrink images
Compression	Lossy for photos, lossless for graphics and icons
Lazy loading	loading="lazy" for below-fold images (native since WordPress 5.5)
LCP image	fetchpriority="high" for hero image — do this manually in your theme
CDN delivery	Serve from geographically distributed edge nodes (Cloudflare, BunnyCDN)

SkySEOManager’s Media Optimizer adds a critical layer that most SEO plugins ignore: use Gemini AI to generate SEO-optimized alt text and image titles for your media library. The Pro version extends this to bulk optimization across your entire library — essential for sites with large media archives where manually writing accurate alt text for hundreds of images is impractical.

Orphan Pages: Invisible to Google

An orphan page is a page with no internal links pointing to it. Google may discover it via your sitemap, but it receives low crawl priority and zero link equity from the rest of your site. Most WordPress sites have more orphan pages than their owners realize.

Finding orphan pages:

• Screaming Frog → Bulk Export → filter for Inlinks = 0
• Ahrefs Site Audit → Orphan Pages report

Fix: Delete and redirect pages with no meaningful content, or add contextual internal links from topically related posts.

AI Internal Linking with SkySEOManager

Internal linking is one of the highest-leverage on-site SEO activities — and one of the most time-consuming to do well at scale. SkySEOManager’s Semantic AI Internal Linking uses vector embeddings — not keyword matching — to:

1. Build a semantic index of your entire site’s topic map
2. Identify the most contextually relevant link opportunities across thousands of posts in seconds
3. Suggest specific anchor text and destination URLs for each link
4. Apply links in resumable batches — pause mid-run when API quota runs out and resume later without losing progress
5. Visualize the resulting link network in a zoomable mindmap

The Internal Link Review Trail logs exactly which keyword anchors were linked to which destination URLs across every run. You can revert any applied link with a single click from the Recent Activity panel — an undo feature that most bulk linking tools don’t offer.

For individual posts, the Editor Internal Linking tab inside the Gutenberg SEO sidebar lets you analyze a single post’s content, review AI-suggested anchors, and apply or reject each suggestion one by one before publishing.

This is the difference between a site that grows its internal link graph intentionally and one that has hundreds of orphan pages that link equity can never reach.

13. What to Build Next: Topical Authority Map

Technical SEO is the foundation. Once it’s stable, topical authority becomes your compounding growth engine. The idea: own the full semantic territory around your niche rather than ranking for isolated keywords.

Based on the entity graph for WordPress SEO, here’s the content cluster to build:

WordPress SEO (Pillar)
  ├── Technical SEO ← (this guide)
  │     ├── Core Web Vitals for WordPress
  │     ├── Crawl Budget Optimization
  │     ├── Schema Markup for WordPress
  │     └── WordPress Speed Optimization
  ├── On-Page SEO
  │     ├── WordPress Content Optimization
  │     ├── Internal Linking Strategy
  │     └── WordPress Keyword Research
  ├── Off-Page SEO
  │     ├── Link Building for WordPress Sites
  │     └── E-E-A-T Signals and Author Authority
  └── Specialty
        ├── WooCommerce Technical SEO
        ├── WordPress Multisite SEO
        └── Multilingual SEO with TranslatePress

Each cluster page reinforces the pillar. Each internal link between them distributes authority bidirectionally. SkySEOManager’s AI Internal Linking engine builds and maintains these connections automatically as you publish new cluster content — the semantic index keeps growing with your site.
