Why unique page titles help
A title tag gives search engines and users a concise description of a page. When many pages share the same title, it becomes harder to understand what makes each URL different. Unique titles are especially important on product, category, location, and article pages.
Common causes of duplicates
Template defaults, copied pages, pagination, URL parameters, duplicate products, and incomplete CMS fields can all create repeated titles. Large websites often accumulate duplication during redesigns or migrations.
How to repair duplicate titles
First decide whether the pages truly need to exist separately. If they do, give each page a title that reflects its unique purpose. If the URLs are duplicates of the same content, consider canonicalization, redirects, or consolidating the pages instead of simply changing the wording.

Write titles for people first
A strong title is clear, specific, and concise enough to communicate the page topic quickly. Avoid stuffing keywords or adding meaningless variations just to make titles technically unique.
