Duplicate content: what it is and how to fix it

Last updated 12 October 2026 · By the XKey team

Is there a duplicate content penalty?

Not for ordinary duplication. Google's own guidance says it picks one version to show and filters out the rest. The exception is copying other people's content on purpose, or making lots of near-identical pages just to rank – that is treated as spam. For most small businesses the real cost is quieter: links and signals get split across copies, and Google may show the wrong version.

What causes duplicate content?

• Several versions of the site: http:// and https://, with and without www.
• Addresses with extras: tracking codes (?utm_source=…), sort orders and filters on shop pages.
• Shop products in more than one collection, each with its own address.
• Manufacturer descriptions copied onto product pages – the same text appears on hundreds of shops.
• Town pages that only swap the place name ("Plumber in Preston", "Plumber in Chorley" with identical text).
• Print versions, tag pages and archives that repeat your posts.

How do I fix duplicate content?

1. Redirect duplicate versions of the site to one https:// address. Check all four versions with the redirect checker.
2. Add canonical tags pointing each page at its main address, so versions with tracking codes or filters count as the original. Most website builders and SEO plugins do this automatically; the free SEO check shows the canonical on any page.
3. Merge pages that cover the same thing into one stronger page, and redirect the old one to it.
4. Rewrite copied text in your own words, especially product descriptions.
5. Make location pages genuinely different – real jobs, photos, reviews and details for each area – or combine them into one page listing the areas you cover.

How do I find duplicate content on my site?

The website audit flags pages that share the same title or description, which is usually the first sign of duplicates. Search Console's Pages report lists addresses marked "Duplicate without user-selected canonical". To check whether your text appears on other websites, use the plagiarism checker.

What if someone copies my content?

Google is usually good at spotting the original, especially if your page was published first and is well linked. If a copy outranks you, ask the site owner to remove it, and if that fails you can file a copyright removal request with Google.

Frequently asked questions

Does quoting another website count as duplicate content?

No. Short quotes with a link to the source are normal. Problems come from copying whole pages or large chunks of text.

Is the same text on my website and Google Business Profile a problem?

No. Matching business details across your site and listings is good. Just don't rely on one copied paragraph everywhere for your main content.

How similar can two pages be?

There's no exact percentage. Ask whether each page gives a visitor something the other doesn't. If not, merge them.
