CanonicalizationFixes
When several URLs show one page, search engines pick a favourite, and it may not be yours. We make your preferred versions unambiguous.
Canonicalization Fixes: what the work involves
A single page can be reachable under http and https, with and without www, with trailing slashes or without, with tracking parameters and through filter paths. Each variant is a separate URL as far as a crawler is concerned. The rel canonical tag is meant to state which one is preferred, but it is only a hint, and sites frequently undermine it: canonicals pointing to redirected URLs, to pages that are noindexed, to different content altogether or to the wrong protocol, while internal links keep pointing at the non-preferred versions.
We list all variants of your important URLs, then compare the signals you send: canonical tags, redirects, internal links, sitemap entries and hreflang. Where they disagree, Google's chosen canonical in URL Inspection tells us what it decided, and we correct the contradictions. Fixes include server-level redirects for protocol and host variants, consistent trailing slash rules, self-referencing canonicals on indexable pages, and clean handling of parameters. We confirm in Search Console that user and Google-selected canonicals finally agree.
Core features
URL variant inventory
Discovery of every way a page can be reached, from protocol and host differences to parameters and pagination, for your key templates.
Signal consistency check
Comparison of canonicals, redirects, internal links and sitemaps for each page to find where they point at different versions.
Self-referencing canonicals
Absolute, correctly formed canonical tags on every indexable page, generated by the template instead of added by hand.
Server-level normalisation
Permanent redirects enforcing one protocol, host, case and slash convention, so variants collapse before they reach a crawler.
Parameter handling
Rules for tracking, sorting and session parameters, covering canonicals, internal link clean-up and robots decisions case by case.
Google-selected canonical review
URL Inspection samples confirming that Google agrees with your declared canonical, with follow-up on pages where it does not.
What we get right before launch
Canonical is a hint only
Google may ignore a canonical that conflicts with other evidence, such as stronger internal links to a different URL. Redirects are the firmer signal when a variant should disappear.
Canonical plus noindex conflict
Combining a canonical to another page with a noindex tag sends contradictory instructions. We choose one intention per URL, since mixed signals produce unpredictable outcomes.
Canonical chains and loops
A points to B and B points to C leaves the outcome uncertain. Every canonical should point directly to a final, indexable, successful page.

Common questions, answered
Canonical tag or redirect: which should I use?
Use a redirect when the duplicate URL should not be reachable at all. Use a canonical when both URLs must stay accessible, such as parameter pages for tracking, but you want one version to collect signals.
Why is Google choosing a different canonical?
Usually because other signals contradict your tag: internal links, redirects, sitemap entries or content differences point elsewhere. We align them all so there is no reason for Google to disagree.
Should every page have a canonical tag?
It is good practice for indexable pages to carry a self-referencing canonical. It protects against accidental parameter duplicates. We generate it in the template so it is applied uniformly and correctly.
Can bad canonicals remove pages from Google?
Yes. A canonical pointing at the wrong page can make Google drop the real one in favour of that target. This is why we test canonicals across templates after any release.

Duplicate content rarely brings a penalty, but it splits your signals and confuses which page should rank. We find it and decide what to do with each case.
Indexing Issue Fixes
A page that is not indexed cannot rank, and the reason is rarely the one people assume. We diagnose each excluded URL and fix the underlying cause.
Faceted Navigation SEO
Filters help shoppers and flood crawlers. We decide which facet combinations deserve to be found and shut the door on the rest.
