Twelve checks in the recorded run: the title and meta description lengths, a single H1, a logical heading order, enough content, the text-to-HTML ratio and image alt text, plus the page tags (viewport, character set, language, social cards), which Rext AI checks on a test page because your theme sets them. Each check shows as passed or failing, and the Checklist adds readability and keyphrase density. --- ### Does a score of 100 mean the article will rank? No. A score of 100 means the article passes every on-page check, which is the part you control in the text. Where it ranks also depends on your site's authority, the links pointing to it, how well it answers the search, and what the pages above it offer. The score tells you the article is ready, not where it will land. --- ### Does it suggest internal links? Yes. At the outline, Rext AI ranks your own published articles by how closely they match the new one and preselects those at 50% or more; you untick any you don't want, and the rest go into the article as links. In the recorded run none were offered; that workspace held only drafts. ## Articles on on-page SEO. ### [How to use on-page optimization to target Google featured snippets](https://rext.ai/blog/how-to-use-on-page-optimization-to-target-google-featured-snippets) August 28, 2026 ### [How small businesses use schema markup to win leads](https://rext.ai/blog/how-small-businesses-use-schema-markup-to-win-leads) September 16, 2026 ### [How Rext AI checks on-page SEO, plus free tools for technical SEO](https://rext.ai/blog/how-rext-ai-handles-on-page-and-technical-seo-for-you) August 13, 2026 ## Related features ### [Internal links](https://rext.ai/features/internal-links) The outline suggests internal links to your own articles, ranked by how closely each one matches the topic. ### [E-E-A-T](https://rext.ai/features/eeat-optimization) A named author, linked sources, and a trust score from 0 to 100% on every article. ### [Keyword research](https://rext.ai/features/keyword-research) Volume, difficulty and search intent for a keyword before anything is written, saved to your library. ## Start with one keyword.
