一个 可读性评分 衡量您的写作易于阅读和理解的程度。它考虑句子长度、词汇复杂度、音节数和段落结构等因素，给出一个对应于美国学校年级水平的数字分数。
Google's goal is to surface content that answers user questions clearly and efficiently. Content that is difficult to read has higher bounce rates, lower dwell time, and fewer social shares — all signals Google factors into rankings. Research has found that content with good readability scores consistently outperforms complex content on the same topic.
我们的免费 在线可读性检查工具 calculates six different formulas and gives you the same SEO readability checks used by leading SEO tools — so you can optimise your content before publishing.
Flesch阅读容易度评分量表——大多数网页内容目标为60–70。
我们的自动可读性检查器同时计算所有六种主要阅读水平公式。以下是每种公式的测量内容。
Most widely used. Scores 0–100 (higher = easier). The formula used by Grammarly and most SEO readability tools.
Formula: 206.835 − 1.015(words/sentences) − 84.6(syllables/words)
将Flesch转换为美国学校年级水平。8分表示文本可供8年级学生阅读。大多数网页内容应以6–8年级为目标。
Formula: 0.39(words/sentences) + 11.8(syllables/words) − 15.59
估算理解文本所需的教育年限。主要关注多音节词（3个及以上音节）。目标：低于12。
Formula: 0.4 × (words/sentences + 100 × complex_words/words)
简单测量行话。对医疗和医学内容非常准确。基于计算30个句子中的多音节词。
Formula: 3 + √(polysyllables × 30/sentences)
使用字符计数而非音节计数——使数字文本更一致。输出美国年级水平。
Formula: 0.0588L − 0.296S − 15.8 (L = letters/100 words, S = sentences/100 words)
使用每词字符数和每句词数。专为实时可读性监控设计。产生美国年级水平估计。
Formula: 4.71(chars/words) + 0.5(words/sentences) − 21.43
我们的 SEO可读性检查器 runs comprehensive checks to score your content. Getting all green bullets doesn't guarantee rankings — but it significantly improves user experience, time on page, and the likelihood that readers will share your content.
缩短句子
谷歌数据显示，普通用户阅读水平为7–8年级。保持平均句子长度在20词以下。在连词（and、but、because）处断开长句，或将其拆分为两个独立的句子。
减少被动语态
被动语态使文本难以理解（"球被约翰踢了" vs "约翰踢了球"）。将被动语态控制在句子总数的10%以内。我们的检查器会高亮显示被动结构，方便您改写。
使用过渡词
Words like "however," "therefore," "additionally," and "as a result" help readers follow your argument. SEO best practice recommends at least 30% of sentences include a transition word or phrase.
保持段落简短
在线读者会快速浏览。超过150词的段落会造成视觉障碍，使用户离开。每段尽量控制在2-4句话以内。
使用小标题
Subheadings (H2, H3) help readers navigate long content and improve scannability. Sections longer than 300 words without a subheading should be broken up.
Many users search for readability checkers online. Different tools measure readability, but they use different approaches — and few are free for all features.
Grammarly使用Flesch阅读易读性公式，并在高级计划中显示0-100的分数。它专注于文档内的写作清晰度，但不检查针对SEO的可读性因素，如小标题分布或过渡词。
