Shopify Canonical Tags Setup and Duplicate Content Fix, One Clear URL for Every Page

Packages start at $390 for Tag Audit and Patch, $790 for Duplicate Clean-Up and $1,490 for Index Control Overhaul. Catalogue size, the number of page types affected and how many apps touch your page head are priced in the calculator, so you see a fixed price first.

It is a line in a page's head that names the preferred address when the same content can be reached at several. Search engines use it as a strong hint about which version to index and rank, so signals combine rather than scatter.

Most themes already print one from the canonical_url object in theme.liquid. Check by viewing a page's source and searching for rel canonical. If there are none, add the line. If there are two, an app is adding its own. We resolve it in a duplicate theme.

Usually not. It means Google found a duplicate address, read your canonical and chose to follow it. It is expected for collection-path and variant URLs. The statuses to investigate are duplicate without user-selected canonical and Google chose different canonical than user.

First check the page listed is truly a duplicate. If so, change the internal links that point to it, so crawlers stop discovering it. If it should rank in its own right, it needs a self-referencing canonical and unique content. We sort which is which.

The usual four are collection-scoped product links, two canonical tags from the theme and an app, parameters on recommendation and search links, and filter or tag pages without rules. The fix is aligned canonicals, internal links and index rules, in that order.

Open a duplicate theme, search theme.liquid for canonical, make sure one tag prints using canonical_url and replace the within filter on product links. It is manageable for a simple theme. Stores with filters, apps or markets usually need expert checking.

Google does not usually apply a penalty. The cost is diluted signals, wasted crawling and the wrong version ranking. On large catalogues that can hold back pages worth the most. The risk is higher when product text is copied from suppliers across many shops.

Shopify can reach one product at /products/handle and also at /collections/name/products/handle. The canonical normally points to the first, but internal links, sitemaps and feeds using the second can lead Google to treat both as real pages.

Yes, it is the first step. We crawl your store and record, for each template, the status code, canonical, robots meta and redirects. We then compare it with Google's own selected canonical in URL Inspection, and list every mismatch with its cause.

Give every page a unique title and meta description, check that robots meta tags match your intent and make sure Open Graph tags do not conflict. Titles repeated across variants and filters are a common problem. We can add a pass for it as an extra.

Apps can print tags, but they cannot decide which pages should rank or notice when two apps conflict. Hire a Shopify SEO expert when Search Console shows many duplicates, when you sell in several markets or when your theme is heavily customised.

Yes. The scope is agreed first and the price is fixed, including two revision rounds. If a store has more than 25,000 products or a headless front end we quote separately, again with scope in writing. There are no open hourly meters.

This service covers duplicate URLs, canonicals and index control. It does not cover link building, ongoing content writing or keyword strategy. If your audit shows thin content as the real issue, we say so and point you to the right next step.
