Why these SEO tools are different
Most free SEO tools ask for an email, cap how often you can use them, or send your text to a server you know nothing about. These run entirely in your browser. You paste, you get a result, and nothing is stored. That makes them fast, and safe to use on drafts and client work.
They are also honest. Where a result is an estimate, such as the pixel width of a title, the tool says so. Where an old SEO habit no longer works, such as the meta keywords tag or sitemap priority values, the guide says that too, with a link to the official documentation.
Where to start
- Publishing a page? Write the snippet in the SERP preview tool, then check the copy with the keyword density checker.
- Launching a site? Generate a robots.txt and an XML sitemap, then run the full SEO audit.
- Sharing links? Build social preview tags and tracked campaign URLs.
What each tool is for
The SERP snippet preview shows how a title and meta description will look in Google on desktop and mobile, with pixel-width meters. The keyword density checker counts words and phrases so you can spot over-repetition. The word counter measures length, reading time and readability and checks text against common limits.
On the technical side, the robots.txt generator builds a valid file with optional AI crawler rules, the sitemap generator turns a URL list into a clean sitemap.xml, and the schema generator writes JSON-LD for articles, products, businesses, organizations and FAQs.
For sharing and measurement, the Open Graph generator previews link cards for social networks, the UTM builder tags campaign links for analytics, and the llms.txt generator creates an optional guide file for AI assistants.
How we keep the tools accurate
Each tool follows the official documentation for the thing it generates: Google Search Central for snippets, sitemaps and structured data, RFC 9309 for robots.txt, the Open Graph protocol for social tags and the sitemaps.org protocol for sitemap files. Where a limit is an estimate, such as title width in pixels, the page says so. We review the tools when the rules change and show the date each page was last updated.
Privacy: nothing leaves your browser
All nine tools are written in plain JavaScript that runs on your device. There is no upload step, no account and no stored history, so you can safely use them on unpublished drafts, client work or internal addresses. The only network requests they make are the ones you ask for, such as loading a share image from a web address you type in.
Tips for getting more from the tools
- Use the tools in sequence as you publish: write the snippet, check the copy, add the markup, then preview the share card.
- Keep the output of each tool in version control or a shared document, so your team can see what was published and why.
- Re-run the tools when you redesign a page, change a template or launch a campaign.
- Combine them with the free site audit to check the whole site, not just a single page.
- Bookmark the ones you use most, since they work offline once the page has loaded.
Three common workflows
Launching a new page. Draft the copy and run it through the word counter and keyword density checker. Write the title and description in the SERP preview. Generate schema markup that matches the page and Open Graph tags for sharing. Publish, then add the page to your sitemap.
Setting up a new website. Create a robots.txt, build a sitemap, publish both at the site root, and submit the sitemap in Google Search Console. Run the full audit to catch the basics: https, redirects, titles, descriptions, headings and mobile settings.
Running a campaign. Build tagged links with the UTM builder, create share cards with the Open Graph generator and keep a log of every link. After the campaign, compare results by source and medium in your analytics.
When a tool is not enough
The tools are designed for single jobs on single pages. They cannot crawl your whole site, measure real load times or see what Google knows about you. When you need that, run the free SEO audit for site-wide checks, and connect Google Search Console for real search data. If you have a task that none of the tools cover, tell us on the contact page: new tools start with real requests.
Browser support and accessibility
The tools work in current versions of Chrome, Edge, Firefox and Safari on desktop and mobile. Controls are large enough to use by touch, forms have visible labels, results are announced to screen readers where they change and everything can be used with a keyboard. If you find a place where a tool is hard to use, please tell us so we can fix it.
Suggest a tool
New tools start with real needs. If you repeat a task that takes too long, such as checking a list of redirects, formatting structured data or validating hreflang tags, tell us about it on the contact page. The most requested ideas are built first, and each new tool goes through the same checks for accuracy, accessibility and privacy as the existing ones.
Free tools FAQ
Are these SEO tools really free?
Yes. There is no account, no usage limit and no paid tier hiding the results. The site is supported by ads, which is why the tools can stay free.
Is my text uploaded anywhere?
No. The tools run as JavaScript in your browser. Text you paste into the keyword density checker or word counter never leaves your device.
Do these tools guarantee higher rankings?
No tool can. Rankings depend on many factors outside any checker's reach. These tools help you avoid common mistakes and produce clean markup, which removes obstacles rather than guaranteeing results.
How do I audit a whole website instead of a single page?
Use the free SEO audit on the home page. It crawls your site, ranks what to fix first and writes an AI fix prompt for each issue.
