The Duplicate content checker finds pages on your site that have similar wording. When two pages say roughly the same thing, Google picks one and hides the rest, sometimes the wrong one.
Available on the Business plan (or a trial). It compares your own pages against each other, not against other websites, and it fetches each page over the internet, so your site needs to be live and reachable.
Finding it#
Go to SEO Manager › Duplicate content.
Running a check#
- 1Click Run check and confirm.
- 2The task queues, then shows Checking for duplicate content... with a live percentage.
- 3It runs in the background, so you can leave the tab and come back.
Each new run replaces the previous results, so there's no separate clear button.
Reading the results#
Every page gets a similarity score against the others. Filter with Similarity: High (80% and up), Medium (60 to 79%) or Low (under 60%). Expand a page to see exactly which pages it's similar to. Aim to keep genuinely similar pages below about 60%.
Short pages can score higher than you'd expect, because they share your header, footer and menus. Treat the score as a prompt to look, not a verdict.
Fixing high-similarity pages#
- Rewrite the intro and headings on one of the pages to focus on a different keyword.
- Merge them if two pages really cover the same topic, and 301 redirect the one you drop.
- Noindex it if the duplicate is a category or filter page, using Page indexation.
Downloads#
Download CSV (which appears once a run finishes) exports the full list. Download duplicate metas is a separate check that finds pages sharing the same meta title or description.
Adding unique, useful content is the real fix. Noindex is a last resort, and a noindexed page still shows up in these results.
Going further
Duplicate content is often a symptom of keyword cannibalisation, where several pages target the same search term. There are free guides on diagnosing and fixing it in the Limecube Marketing learning centre.
