Shopify SEO tips: what your store already does and what to fix

Shopify's theme documentation describes three main pieces of SEO metadata a theme includes in the page's head: the title tag, the meta description and canonical URLs. Shopify says the title and description for most pages can be set in the Shopify admin, and its example theme code outputs a canonical URL using the global canonical_url object.

Shopify also generates a robots.txt file automatically. In its developer documentation, Shopify says it generates a default robots.txt file that works for most stores. That file tells search engines which pages can or can't be crawled, using groups of rules for specific crawlers and an optional sitemap URL.

So the technical foundation is usually in place. Your job is the content that sits on top of it.

Google's SEO Starter Guide explains that the title link in search results is built from sources including the words inside the title element and other headings on the page. In Shopify, you set most page titles in the admin.

A good product title says what the item is in the words a shopper would use. Keep each one unique, so two products never compete with identical titles.

Google says it primarily uses the content on the page to create the snippet under your title in search results, and that it sometimes uses the meta description when that gives a more accurate description of the page.

A few rules from Google's snippet documentation:

• Make each one unique. Google says identical or similar descriptions on every page aren't helpful when individual pages appear in search.
• Skip keyword lists. Google says descriptions made of long strings of keywords don't give users a clear idea of the page and are less likely to be shown.
• Don't count characters obsessively. Google says there's no limit on how long a meta description can be, but the snippet is truncated as needed, typically to fit the device width.

Google's own example contrasts a description that is only a list of sewing supplies with a better one that explains what the shop sells and adds details like opening hours and location. For a product, a strong meta description says what it is, who it's for and one detail that sets it apart.

Shopify lets developers customize robots.txt by adding a robots.txt.liquid template, and it supports adding or removing rules. But Shopify also strongly recommends using the provided Liquid objects whenever possible, because the default rules are updated regularly to keep SEO best practices in place.

One misunderstanding to avoid: robots.txt doesn't hide pages from Google. Google's robots.txt guide says the file is mainly used to avoid overloading a site with requests and is not a mechanism for keeping a web page out of Google. To keep a page out of search results, Google points to a noindex rule or password protection.

An online store can end up showing the same product at more than one address. Google's starter guide calls this duplicate content and says search engines choose a single URL (the canonical URL) to show users. Duplicate content isn't a spam violation, but it can confuse shoppers and waste crawling time.

Shopify's documented approach is a canonical tag built from the canonical_url object. If you edit your theme, or a developer builds a custom one, confirm the canonical tag is still in the page's head.

Once the basics are in place, content decides the rest. The starter guide asks you to create content based on what you know about the topic instead of copying others. For a store, that means writing your own product descriptions, with the questions customers actually ask you, instead of pasting the supplier's text.

Images matter too. Google recommends high-quality images placed near relevant text, which helps it understand what each image shows. Use clear product photos and describe what's in them.

Google's starter guide suggests a quick first test: search Google for your store using the site: search operator followed by your domain. If your products show up, Google has found them. If they don't, check Google's technical requirements before rewriting anything. Google also says it finds pages mainly through links from pages it already crawled, so link to your most important collections and products from your homepage and menus.

1. Trust the platform's defaults for robots.txt and canonical tags.
2. Write a unique title for every product, collection and page.
3. Write meta descriptions for shoppers, not keyword lists.
4. Use noindex, not robots.txt, to keep a page out of Google.
5. Confirm canonical tags survive theme changes.
6. Write your own product descriptions and use sharp photos.
