Readability is how easily readers can understand the text. Well-structured content with short paragraphs, lists and headings ranks better and attracts more traffic.
Readability measures how easy it is for the reader to understand the content. Factors: (1) Paragraph length (2-3 sentences vs. 10 dense sentences); (2) Complex vs. simple words; (3) Use of lists (bullets, numbered); (4) Spacing and visual formatting; (5) Sentence length (on average: 10-15 words). Google does not measure readability directly, but easy-to-read pages = more time on page, less bounce, more internal links. Metric: Flesch Reading Ease (0-100, >60 is good).
Hard-to-read content = visitors who leave quickly (high bounce rate). Bounce rate is an indirect ranking signal. Easy-to-read content = longer traffic duration = better ranking.
Source: Yoast — Readability AnalysisOn-page SEO covers all the optimizations made directly on your site's pages — titles, headings, content, meta descriptions and URL structure.
Heading structure is the correct H1 → H2 → H3 hierarchy that helps Google and users understand how content is organized.
Keyword density is the percentage of target keywords out of a page's total words. Too low = weak optimization; too high = penalized keyword stuffing.
The meta description is a 150-160 character text placed in the HTML code that appears under the page title in Google results and influences the click-through rate (CTR).
