Scan your WordPress site for internal duplicate content. See which pages overlap, how much they share, and what to fix — before it costs you rankings. Optional Copyscape integration checks the wider web too.

The Problem
Boilerplate paragraphs copied across service pages. Product descriptions reused with minor tweaks. Category pages that overlap with tag archives. You don't notice it — but Google does, and it dilutes your authority across competing URLs.
Most site owners only discover duplicate content when rankings drop. NitroEcho finds it while you can still fix it.
Features
Compares every page against every other page on your site. Detects partial matches, near-duplicates, and boilerplate overlap — not just exact copies.
Optional external check powered by Copyscape Premium. Find if your content has been copied elsewhere on the web — or if you've accidentally duplicated someone else's.
Each page pair gets a percentage overlap score. Green means unique. Amber means worth reviewing. Red means Google is probably confused about which page to rank.
See exactly which paragraphs are duplicated, between which pages, with highlighted overlap. Know what to rewrite, merge, or canonical — not just that a problem exists.
No monthly fee. No annual subscription. Scan when you need to, pay only for what you use. Credits are shared across all NitroShock plugins.
Run a scan before publishing new content to make sure it doesn't overlap with something already on your site. Catch the problem before it goes live.
Detection Modes
Compares pages within your own WordPress site. Finds boilerplate overlap, copied service descriptions, and thin variations.
Checks your content against the entire web via Copyscape Premium API. Requires your own Copyscape API key.
Scan Output
Click any row to see the exact overlapping paragraphs highlighted side by side.
Getting Started
Upload the plugin zip, activate it, and enter your NitroShock license key. The NitroEcho menu appears in your admin sidebar.
Scan all published pages and posts, or select specific post types. Set your similarity threshold — 40% is a good starting point for most sites.
NitroEcho compares every page pair, scores similarity, and flags overlaps. A 50-page site takes a few seconds. Large sites with 500+ pages run in the background.
Results are sorted by severity. Click any pair to see the overlapping paragraphs highlighted. Then decide: rewrite, merge, add a canonical tag, or noindex the weaker page.
Duplicate content dilutes your rankings. Find it, fix it, and give Google one clear answer for every query.
