Internal Duplicate Content Checker Find repeated content across your own pages

When several of your pages say the same thing, search engines struggle to decide which one to rank. We crawl your site, measure duplicate, common and unique content on every page, show which pages repeat each other — and highlight the exact text.

How to use it

Find duplicate content in three steps

  1. 1

    Enter your website

    Type your home page and choose how many pages to scan. External link checks are off by default to keep the scan fast.
  2. 2

    We compare every page

    We crawl your site like a search engine, read the visible text of each page and compare it with every other page you have.
  3. 3

    Open the worst pages

    Sort by duplicate percentage, open a page to see the repeated text highlighted and the pages it overlaps with, then rewrite, merge or canonicalise.
How it works

Duplicate, common and unique content explained

Every word on every page is classified, so you see not only how much is repeated, but where.
01

Duplicate content

Text that also appears on a few of your other pages. This is what competes in search results and what you should fix first.
02

Common content

Text found on a large share of your pages — menus, footers, sidebars, calls to action. Normal in moderation, but it dilutes thin pages.
03

Unique content

Text that appears on just one page. The more of each page that is unique, the stronger its chance to rank for its own topic.
04

Matching pages

For every page we list the pages it overlaps with most and how many words they share, so you know exactly which pairs to fix.
05

Highlighted text

Open any page to see its text colour-coded — red for duplicate, amber for common, plain for unique.
06

Site vs others

Compare your duplicate and common content, page size, speed, words and links per page with other sites scanned by XcodeFix.
Fixing duplicate content

Six ways to make every page unique

Duplicate content is usually a template or process problem. These fixes deal with the cause.
01

Rewrite templated pages

City, service and product pages built from one template need genuinely different details: local proof, specific examples, real FAQs.
02

Merge near-duplicates

If two pages target the same intent, combine them into one stronger page and 301-redirect the other.
03

Use canonical tags

When variants must stay (sorting, filters, print versions), point their canonical tag at the main version.
04

Trim boilerplate

Long repeated blocks in sidebars and footers inflate common content. Keep them short and move detail to its own page.
05

Control URL parameters

Tracking and filter parameters can create many copies of one page. Use canonicals and consistent internal links.
06

Write unique titles and descriptions

Duplicate titles and meta descriptions are listed in your report — give every page its own.

FAQ

Duplicate Content Checker FAQ

Still curious? Ask our SEO team through the free audit form.
What is internal duplicate content?
Internal duplicate content is text that appears on more than one page of the same website — for example the same service description on several city pages, or product pages that differ only by colour. Search engines then have to choose which version to rank, and often rank none of them well.
What is the difference between duplicate, common and unique content?
Duplicate content is text shared between a few of your pages. Common content appears on a large share of your pages — usually the menu, footer and sidebars — and is normal. Unique content appears on only one page. Healthy sites keep duplicate content low and unique content high.
How does the checker find duplicate content?
We crawl your pages, read the visible text and break it into overlapping eight-word sequences. Sequences found on many pages are classed as common, those shared by a few pages as duplicate, and the rest as unique. Each page then gets a duplicate percentage and a list of the pages it overlaps with most, and you can open any page to see the repeated text highlighted.
How much duplicate content is too much?
There is no fixed limit, but a site-wide duplicate figure above about 15–20% usually means templated pages are competing with each other. Individual pages that are more than 30% duplicate deserve attention first.
Does the checker look at other websites?
No — it compares your pages with each other only (internal duplicates). To find copies of your content on other sites you need a plagiarism search across the web.
How do I fix duplicate content?
Rewrite each page so its main content is genuinely unique, merge near-identical pages and redirect the extras, or add a canonical tag pointing to the preferred version when the duplicates must stay. Our free detailed audit can recommend the right fix for each page.
