How to fix duplicate title on Shopify
Write a unique, descriptive title tag for every page on your store so no two pages share the same title.
Steps for Shopify
- For individual pages/products: Go to Online Store → Pages (or Products / Collections), open the item, scroll to the bottom 'Search engine listing' section, click 'Edit', and update the 'Page title' field.
- For the homepage: Online Store → Preferences → set the 'Homepage title' field.
- For bulk edits across many products: use the Shopify bulk editor (Products → select multiple → Edit products) or export a CSV (Products → Export), edit the 'Title' and 'SEO Title' columns in a spreadsheet, then re-import.
- To control titles via theme (for category/blog archive templates): Edit your theme code at Online Store → Themes → Edit code. Open the relevant layout/template file (e.g. layout/theme.liquid) and locate the <title> tag; add Liquid logic such as {{ page_title }} | {{ shop.name }} to generate unique titles automatically.
- Consider an SEO app (e.g. Plug In SEO, SEO Manager, or Yoast SEO for Shopify) for bulk template-level title management across thousands of pages.

A title tag is the short text that appears as the clickable blue headline in Google search results and in the browser tab when someone visits your page. Every page on your store has one, and it lives in the HTML `<head>` section as `<title>Your Page Name</title>`. A "duplicate title" means two or more of your pages use exactly the same title text — Google and other search engines see them as potentially interchangeable, which hurts both pages.
Google uses the title tag as one of the strongest signals to understand what a page is about — if two pages share a title, Google may struggle to decide which one to show for a given search query, effectively making both pages compete against each other (a problem called keyword cannibalization). Duplicate titles also reduce click-through rates in search results because shoppers see identical headlines and can't tell which link leads to what they actually want. In practice this means less organic traffic to both pages. Google's own guidance explicitly states that every page should have a unique, descriptive title; failing to do so is one of the most commonly cited on-page SEO mistakes.
