Build escaped <link rel="canonical"> snippets for absolute landing URLs — one tag per line in batch mode, optional self-closing form. Markup is produced only in your browser; nothing is uploaded, consistent with
APK Analyzer and
APK String Extractor. Pair with
Meta Tag Generator and
Sitemap Generator for a coherent site setup.
Output uses HTML attribute escaping for &, quotes, and < inside href.

A rel="canonical" link tells search engines which URL should be treated as the primary version when duplicates exist (tracking parameters, print views, alternate paths). It is a hint, not a command — but it is a standard part of technical SEO. Like
APK String Extractor, this tool never sends your URLs to DroidXP for processing.
The href must be an absolute URL. Each HTML document should expose one coherent canonical — duplicate or conflicting tags in the same response confuse crawlers. Align canonicals with your redirects and internal links.
Google can read canonicals from a <link> in the document or from an HTTP Link header. Use one mechanism consistently; conflicting signals on the same response should be avoided.
og:url should usually match your canonical for the same page. Sitemap entries should list URLs you want indexed — often the same canonical set. Campaign links from the
UTM Builder still land on a page whose canonical should be the clean, non-fragment URL you want indexed.
Inputs may be saved in localStorage on your device. That data is not uploaded when you type — only static assets load from DroidXP.
/>.<head> (or CMS SEO field), deploy, and verify coverage in Search Console.No. Tags are formatted in your browser — the same local-only stance as APK Analyzer and APK String Extractor. Optional localStorage only saves fields on your device.
Yes. Google expects a full absolute URL in the href (https://… or http://…). Relative paths in canonical are easy to mis-resolve across hosts and protocols.
Exactly one visible canonical signal per HTML document — multiple conflicting link rel="canonical" tags confuse crawlers. Fix duplicates at the template level.
Both can express a canonical URL; Google supports either when consistent. Do not send conflicting canonicals via header and HTML on the same response.
Usually yes for production sites served over TLS — match your live, indexable URL users and Googlebot reach.
The href should match your chosen canonical form — include or omit trailing slashes consistently site-wide; query strings belong in the canonical only if that exact URL is the canonical document.
It is a strong hint, not a guarantee. Google may still choose a different canonical in edge cases — reduce duplicates in navigation, internal links, and redirects too.
rel=canonical tells search engines which URL is preferred for indexing; og:url is for social previews; sitemaps list URLs for discovery — they should agree but serve different roles.
Yes — one link tag per valid line. Use batch mode when each line is the canonical href for a different page template you are wiring up.
Yes — drafts stay in your tab; nothing is sent to DroidXP to render the snippet.
