What meta descriptions do
A meta description is a short summary that search engines may use as a search-result snippet. It is not a guarantee—search engines can generate different snippets—but a useful description can explain why a page deserves a click.
Why duplicates appear
CMS templates often reuse one default description across many pages. Product catalogs and location pages can also inherit repeated text. This makes pages look less distinct and can reduce the usefulness of manually written metadata.
Prioritize important pages
You do not need to panic over every duplicate on a huge site. Start with pages that receive impressions, represent important products or services, or target different search intents. Write a specific summary that matches what each page actually offers.

Avoid boilerplate-only descriptions
Brand phrases can be reused, but the description should still contain page-specific information. A short accurate description is better than a long generic block repeated sitewide.
