SEO Tools
Free online SEO tools: meta tag generator with SERP preview, robots.txt generator, and UTM campaign URL builder. No signup.
6 tools
SEO Tools generates three small pieces of a site's technical setup that are easy to get subtly wrong by hand: the head metadata of a page, the site's crawl-rules file, and a tracking-tagged campaign link. The Meta Tag Generator writes the title, description, canonical and robots tags with a length guide and a search-result preview. The Robots.txt Generator builds a valid file for one user-agent. The UTM Campaign URL Builder adds the five standard utm_ parameters to a link. Each escapes or encodes its input and runs locally.
Which tool should I use?
- Use the Meta Tag Generator to draft or review a page's title and description against the 60/160-character guides and to see the desktop search preview before shipping.
- Use the Robots.txt Generator to assemble Allow/Disallow rules, a crawl-delay and a sitemap line for a single user-agent; run it again for a second agent's block.
- Use the UTM Campaign URL Builder to tag a newsletter, ad or social link; it keeps any existing query string and fragment and replaces UTM values already present rather than duplicating them.
Limitations and things to know
- The character counts are guidance, not a ranking rule — no search engine publishes a hard title or description length.
- The Meta Tag Generator writes only title, description, canonical and robots — no Open Graph, Twitter Card, viewport or charset tags — and its preview is desktop-style.
- robots.txt controls crawling, not indexing, and is not access control: any path you list stays publicly visible in the file. The generator emits one user-agent group and does not check wildcard syntax.
- The UTM builder adds only the five standard utm_ parameters and does not lower-case or otherwise normalise the values you enter.
