Chrome side-panel extension

Compare SERPs for Up to 10 Keywords Without Leaving the Page

Paste 2 to 10 keywords into the side panel and Optiwing compares their live search results, showing how much they overlap, which URLs they share, and whether they deserve one page or several. The fastest way to catch keyword cannibalization before you write.

How It Works in the Side Panel

Paste 2 to 10 keywords

Drop your candidate keywords into the side panel, one per line. These might be terms you are deciding between, variations you suspect overlap, or a small cluster you want to sanity-check before committing to a content plan.

Set the market

Pick country, language, device, and search engine. The comparison runs against live results for that exact market, so the overlap you see reflects the SERPs your real audience gets.

Compare for 1 credit per keyword

Optiwing pulls the top 10 organic results for each keyword and measures how much they share. Comparing 5 keywords costs 5 credits. Results come back in seconds.

Read the overlap and decide

You get an overall similarity score, a plain-language recommendation, pairwise similarity between every keyword, and the exact URLs that show up across SERPs. High overlap means one page can rank for all of them; low overlap means separate pages.

What You Get

SERP Similarity Score

One headline percentage for how alike the results pages are, plus a recommendation on whether to target the keywords together or apart.

Pairwise Breakdown

Similarity for every keyword pair, so you see exactly which terms cluster together and which one is the odd one out.

Shared URLs Highlighted

The common URLs across SERPs are listed and flagged in each keyword's results, the clearest signal that Google treats the queries the same way.

Localized Comparison

Compare by country, language, device, and engine. Intent overlap changes by market, so you test the one you actually rank in.

Decide Before You Write

Catch cannibalization and merge-or-split decisions up front, in the side panel, without a spreadsheet or a separate tab.

1 Credit Per Keyword

Pay only for the keywords you compare, from your Optiwing balance. First 100 credits are free, and purchased credits never expire.

The extension uses your Optiwing account and credits, the same wallet as the web app. A comparison costs 1 credit per keyword, so comparing 8 keywords costs 8 credits. New accounts get 100 free credits, and purchased credits never expire.

Install and Connect

Install from the Chrome Web Store

Add Optiwing SEO Tools to Chrome. It runs as a side panel, so it opens next to any tab without leaving the page you are on.

Sign in to Optiwing once

Open app.optiwing.com and sign in (or create a free account with 100 credits). The side panel piggybacks on that web session to authenticate, so there is no separate extension login.

Open the side panel and go

Click the Optiwing icon to open the panel. Your live credit balance shows in the header, and every check draws from the same wallet as the web app.

Frequently Asked Questions

What does SERP comparison actually tell me?

It measures how much the live search results overlap across your keywords. If two keywords return mostly the same ranking URLs, Google reads them as the same intent and one page can rank for both. If they barely overlap, they need separate pages. The panel gives you a similarity score, pairwise numbers, and the shared URLs behind it.

How many keywords can I compare at once?

Between 2 and 10 keywords per comparison. For larger sets, run several comparisons or use the keyword grouping workflow, which clusters hundreds of keywords by the same SERP-overlap signal.

How is this different from keyword grouping?

Grouping clusters a large list into content groups automatically. SERP comparison is the focused version: a small head-to-head on 2 to 10 keywords when you need a fast merge-or-split decision, with the pairwise detail and shared URLs shown directly.

Do I need a separate extension login?

No. Sign in to app.optiwing.com in your browser and the side panel uses that session. Your live credit balance shows in the panel header.

How much does it cost?

One credit per keyword in the comparison. Comparing 5 keywords costs 5 credits. You get 100 free credits on signup with no credit card, and purchased credits never expire.
