Free Online SEO Tools
Create meta tags, robots.txt, XML sitemaps, schema markup and clean URL slugs, or check canonicals, keywords and search previews.
Meta Tag Generator
Generate HTML title, meta description and Open Graph tags for a web page, then copy the finished markup.
Robots.txt Generator
Choose crawler access rules and generate a ready-to-use robots.txt file for your website.
Sitemap Generator
Enter your website URLs and generate a valid XML sitemap file for search engine crawling and indexing.
Keyword Density Checker
Paste content to see how often words and phrases appear, including counts and percentage density.
SERP Preview
Preview how a page title, URL and meta description may appear in Google search results before publishing.
Canonical Tag Checker
Enter a page URL to find its canonical tag and verify which URL the page tells search engines to index.
Schema Generator
Generate copy-ready structured data markup for supported schema types without writing JSON-LD by hand.
Slug Generator
Turn a page title or phrase into a clean, lowercase, hyphenated URL slug that is easy to read and share.
Meta Tag Generator, Robots.txt Generator, Schema Generator, Slug Generator, SERP Preview and Keyword Density Checker all run in your browser — you type or paste content and get results with nothing sent anywhere. Sitemap Generator and Canonical Tag Checker are the two exceptions: they fetch a URL you give them from our server (with basic protection against pointing them at internal/private addresses) so they can read that page's actual HTML, which a browser can't do across other domains.
SERP Preview is useful for checking how a title and meta description will actually look truncated in Google's results before you publish. Schema Generator outputs ready-to-paste JSON-LD for Article, Product and FAQPage structured data — the same kind of markup this site uses on its own tool pages.
None of these require any SEO background to use — each one simplifies a single common task, like building a robots.txt file or checking a canonical tag, down to filling in a form and copying the result. They're all free, with no signup, and work on desktop, tablet or phone through a browser.
