# SEO and web publishing tools

Use these tools to prepare the details around a web page: its title and description, link-preview metadata, canonical URL, crawl instructions and sitemap entries. Meta Tag Generator and Open Graph Generator produce markup from the values you enter. SERP Snippet Preview lets you review the shape of a search listing. UTM Link Builder adds campaign parameters to a destination URL so a compatible analytics setup can distinguish that visit.

Generated markup still needs to match the published page. A canonical URL should identify the version you want indexed, and a sitemap should contain reachable URLs you actually intend search engines to discover. Use robots.txt rules with care: preventing crawling does not reliably remove a URL that is already indexed. Check the finished file in the context of your own site before deploying it.

Previews are approximations. Search engines may rewrite titles and descriptions, and social platforms have their own caching and display rules. Structured data describes visible content; it does not promise a special search result. Likewise, a sitemap helps discovery but does not guarantee indexing or ranking. After publishing, inspect the actual HTML and response behavior, then use the search engine's webmaster tools to see what was crawled and whether any errors were reported.
