How to fix duplicate title on Shopify

Steps for Shopify

1. For individual pages/products: Online Store → Pages (or Products / Collections) → click the item → scroll to 'Search engine listing' section at the bottom → edit 'Page title'.
2. For theme-level templates (so every product page auto-generates a unique title): Online Store → Themes → Edit code → open the relevant layout/template file (e.g. 'layout/theme.liquid') and confirm the <title> tag uses dynamic Liquid variables such as {{ page_title }} — Shopify populates this from the product name automatically.
3. For bulk updates across many products, use a bulk-edit CSV: Products → Export → edit the 'SEO Title' column in the CSV → import back.
4. Install a dedicated SEO app (e.g. Plug In SEO, SEO Manager, or TinyIMG) to audit and bulk-edit title tags store-wide from one dashboard.

What is duplicate title?

The title tag is the line of text that appears as the clickable headline in Google search results and in your browser tab. When two or more pages on your store share the exact same title tag, search engines — and shoppers — cannot easily tell them apart. A duplicate title means at least one page is missing its own distinct identity, usually because a template has been applied without customisation, a CMS generated a fallback title, or pages were accidentally copied without updating their metadata.

Google uses the title tag as one of its primary signals to understand what a page is about. Duplicate titles confuse its crawlers, can cause the wrong page to rank (or neither page to rank well) for a given query, and split ranking authority between pages that should each stand on their own. For shoppers, identical titles in search results make it impossible to choose between two links — reducing click-through rates and, ultimately, revenue. Google may also silently rewrite a duplicate title to something generic, stripping away any keyword targeting you intended.
