Launched My First SEO Tool — A Free SERP Similarity Checker

If you’ve ever wondered whether two keywords should be targeted on the same page or split into separate articles, you’re not alone.

As SEOs, we know that keyword strategy isn't just about search volume or keyword difficulty—it’s about understanding search intent and how Google interprets it.

That’s exactly what inspired us to build the SERP Similarity Checker — a free, no-login tool that instantly compares Google search results for any two keywords.

What is a SERP Similarity Checker?

A SERP similarity checker compares the Google Search Engine Result Pages (SERPs) for two keywords. It tells you how many of the top-ranking URLs are common between them.

If a high percentage of URLs overlap, it means Google sees those queries as closely related — and targeting both in a single piece of content makes sense.

If there’s little to no overlap, then the search intent is likely different, and you’re better off creating two separate pages.

Our tool automates this analysis using live, geo-specific SERP data pulled directly from Google. You’ll see:

The percentage of overlapping URLs

• A list of common websites
• A side-by-side comparison of top results
• A Venn diagram that shows the similarity visually

Also, the tool displays a SERP similarity confidence score along with a clean Venn diagram so you can instantly see how much overlap exists.

Why This Tool Matters for Your SEO

Smarter keyword decisions lead to better-performing content. Here’s how this tool helps:

• Save time: No more manual SERP comparisons.
• Plan content efficiently: Know when to combine or separate keywords.
• Avoid cannibalization: Prevent pages from competing with each other.
• Maximize ROI: Target more keywords per page—when it makes sense.
• Map keyword intent: Understand how Google interprets the terms you're targeting.

Let’s say you’re wondering if “best running shoes” and “top sneakers for running” can be combined.

Instead of guessing, run them through the tool. If the overlap is high, you’re safe combining them into one comprehensive article.

How to Use the Tool

It’s incredibly simple:

1. Enter two keywords.

2. Choose your country and language.

3. Click Compare.

4. View the results: overlap %, comparison table, common domains, and the Venn diagram.
