SEO tools for content that gets found.
Check keyword density, score readability, generate clean meta tags, and turn titles into tidy URL slugs. Quick on-page checks that help your content rank, all in your browser.
SEO tools are on-page helpers that check and prepare content so search engines and readers both understand it. This set covers the core on-page tasks: measuring keyword density, scoring readability, generating title and description meta tags, and creating clean URL slugs.
They focus on what you control directly, the words on the page and the markup around them. Each tool runs in your browser and updates as you edit, so you can tune a draft before you publish.
Use the readability score to keep prose clear, the keyword density checker to avoid over- or under-using a term, the meta tag generator to write the title and description a search result shows, and the slug generator to produce a short, readable URL.

Frequently asked questions
What are SEO tools?
SEO tools help you prepare on-page content so it ranks and reads well. The common on-page ones check keyword density, score readability, generate meta tags, and create URL slugs. ToolBook runs these in one tab so you can tune a draft before publishing.
Are these SEO tools free to use?
Yes. Every SEO tool here is free and runs in your browser, updating live as you edit your text.
What is a good keyword density?
There is no exact target, but most on-page guidance suggests keeping a primary keyword in a natural range of roughly half a percent to two percent of the total words. The keyword density checker shows your actual percentages so a term does not read as stuffed or missing.
What should a meta description contain?
A meta description is the summary a search result shows under the title. Aim for roughly 150 to 160 characters, lead with the answer or benefit, and include the main keyword once. The meta tag generator previews the length as you type.
Do meta keywords still affect ranking?
No. Google ignores the meta keywords tag for ranking. Put your ranking terms in visible content like the title, headings, and body, and use the meta tag generator for the title and description, which do affect how your result appears.
