More clarity for your SEO strategy

Companies invest time, budget and expertise in content creation – but often without knowing whether they are separating the right topics or inadvertently duplicating them.

The central question is:

Should similar search terms each have their own pages – or is a single, comprehensive article sufficient?

The answer is provided by SERP Overlap Analysis – an intelligent SEO tool that shows how much search results of different keywords overlap and thus helps to avoid keyword cannibalization.

This method brings structure, efficiency and data clarity to your SEO strategy – especially for B2B companies whose content often contains technical or specialized search terms.

What is SERP overlap analysis?

SERP stands for Search Engine Results Page – the results page of a search engine such as Google.
A SERP overlap analysis compares the top results of several keywords with each other to find out:

• How similar are the domains displayed?
• Which content covers several search queries at the same time?
• When is a joint article worthwhile – and when separate pages?

Through this analysis, companies understand how Google interprets the search intent behind certain keywords.
This is crucial for deciding whether content should be combined or separated.

Example:
If the search results for “CRM software comparison” and “best CRM tools” are 80% identical, Google considers both terms to have the same search intent.
A single, high-quality page can therefore cover both – more efficiently, more clearly and with less risk of mutual cannibalization.

Why keyword cannibalization is an SEO problem

Keyword cannibalization occurs when several pages of a website compete for the same search term.
The consequences can be serious:

• Google does not recognize which page is more relevant
• Rankings and clicks are distributed across several URLs
• No page gets enough authority to reach top positions
• The internal link structure is diluted

Especially in the B2B sector, where topics are closely interwoven (e.g. “ERP systems”, “ERP software for SMEs”, “ERP providers in Germany”), this can happen quickly.

SERP overlap analysis allows such conflicts to be identified at an early stage.
The result:
A clearer content structure, a consistent topic structure and stable rankings.

How SERP Overlap Analysis works

The principle is simple but effective:
The tool automatically analyzes the top 10 results on Google for several keywords at the same time and measures their overlap.

1. collect SERP data

First, the search results for the selected keywords are retrieved via crawling or API.
This creates a database with the most important URLs and domains.

2. overlap calculation

The system checks how many of the domains appear in both keyword sets.
The greater the overlap, the more similar the search intent.

One example:

• 7 identical domains → 70 % overlap → Combine content
• 2 identical domains → 20 % overlap → separate articles make sense

3. weighting of the top results

Hits in the top 3 are weighted more heavily, as they best reflect Google’s understanding of the search intent.
If these are identical, merging them almost always makes sense.

4. AI-supported interpretation

An integrated AI provides a recommendation:

“A single, comprehensive post could effectively cover all three keywords and avoid duplicate content.”

This automated assessment saves time – and provides data-supported recommendations for action.

Example: Several keywords – one content piece

Let’s take the terms “Best SEO Tools”, “SEO Software” and “SEO Tools 2025”.
The SERP overlap analysis shows:
Top results such as Backlinko, Sapia or Morning Score appear for all three search terms.

This means:

• Google recognizes the same search intention.
• Instead of three articles, one page that integrates all variants is sufficient.
• This strengthens the authority of the content and avoids internal competition.

Result:
Less effort, clearer structure and more sustainable ranking.

Extended application for B2B companies

1. structure topic complexes

Many B2B websites have keywords such as:

• “Hydraulic systems in mechanical engineering”
• “Buy hydraulic control unit”
• “Hydraulic solutions for industrial systems”

A SERP overlap analysis can be used to check whether Google is separating or merging these topics.
This allows editors to decide which pages should be merged or optimized separately.

2. identify content gaps

If two keywords hardly overlap, an opportunity arises:
A new, focused article can close the gap between the topics – such as “hydraulic systems for energy efficiency”.

3. relaunch or migration projects

During website relaunches, the analysis helps to consolidate outdated content.
prevents duplicate or similar pages from going back online – a common SEO mistake in the B2B sector.

Advantages for B2B companies

• Avoidance of content duplicates: Each page receives a unique keyword assignment.
• More efficient content production: One article instead of three – saves time and resources.
• Stronger authority: A central, comprehensive article ranks more stable and is linked more often.
• Clearer content structure: Users and search engines find information faster.
• Better UX: Less overlap means better navigation and internal linking.
• AI-supported insights: Decisions based on data instead of gut feeling.

Conclusion: Smarter content strategies through SERP overlap

SERP overlap analysis is more than just a technical SEO tool for B2B companies – it is a strategic compass.
It helps to bundle topics, save resources and avoid duplicate content.

At a time when search intent is more important than keyword density, this method enables more precise SEO decisions.
The result:

• More focus
• Less cannibalization
• Higher visibility in search engines

If you want to be successful in the long term, you should firmly integrate SERP overlap analysis into your SEO and content processes – as a bridge between technical analysis and strategic thinking.
