Frequently Asked Questions About Free SEO Tools
Are these SEO tools completely free?
Yes. The tools on this page are designed to provide basic SEO checks and calculations directly in your browser without requiring an API key or paid SEO software.
Do these SEO tools require an API?
No. These tools are designed to work with information entered or pasted into the page. They do not require an external SEO API.
Can I use these tools for WordPress websites?
Yes. You can use them for WordPress websites as well as other HTML websites. For HTML-based checkers, you can paste the source code of a page into the relevant tool.
Does the SERP preview show the exact Google result?
The SERP preview is a visual approximation. Search engines can rewrite titles and descriptions and may display results differently depending on the search query, device and other factors.
What is a good keyword density?
There is no universal keyword-density percentage that guarantees rankings. Natural language, search intent, useful information and topical relevance are more important than repeatedly inserting a keyword.
Why does the Meta Tag Checker ask me to paste HTML?
A browser-only tool cannot reliably fetch every external webpage because of security and cross-origin restrictions. Pasting the HTML lets the tool inspect the source without requiring an external API.
What does a canonical URL do?
A canonical link element can indicate the preferred URL for substantially similar or duplicate pages. It is one of several signals search engines can use when selecting a representative URL.
Why is image alt text important?
Alt text provides a textual description of an image for users who cannot see it and can help search engines understand image content. Decorative images can use an empty alt attribute when appropriate.
Can I generate a sitemap for my whole website with this tool?
This browser-based sitemap generator creates XML from the URLs you provide. It does not automatically crawl your entire website. Large websites should normally use a dedicated sitemap system or CMS/plugin.
Does a higher SEO score guarantee higher Google rankings?
No. A basic on-page SEO score is only a diagnostic guide. Search visibility depends on many factors, including content relevance, technical accessibility, links, site quality, competition and search intent.
Need Help Improving Your Website SEO?
Free tools can help identify common SEO issues, but a complete SEO strategy requires understanding your website, market, competitors, content and search intent.
