Why You Need Keyword Clustering
Save Dozens of Hours on Refining Semantics
Less routine — more strategy. Manual clustering is endless tables, mistakes and hours of pencil pushing. Thundo will do everything for you effortless and error‑free: automatically group keywords by SERP Top regardless of how many phrases you have — 300 or 30000 and even more. Get the result in minutes and proceed to what really matters: strategy, structure and content.
Get a Ready‑Made Site Structure
Create a reliable website structure: keyword clusters will lay foundation for future sections, categories, and landing pages. The tool buckets phrases based on the identical URLs in SERP Top‑10 and put them into groups. Sound website architecture is the very grammar of sustainable organic growth. Clusters help to expand site structure, map out content, launch ad campaigns and elaborate SEO‑strategy.
Form a Content Plan That Works
Each keyword group is a potential target page. You’ll know for sure, what topics you need to cover, what phrases to unite and where it would be better to create a new landing page. Clustering will help you to identify content gaps, avoid cannibalization and enhance coherence of your semantic core. Content that works starts from the semantics distributed the right way!

Perform clustering in all the local Google domains, locations, and languages. Work with international semantics and clients from all over the globe and build websites relevant to the exact country and location you’re targeting your SEO.
Make Your Content Strategy Shine Bright
Avoid Keyword Cannibalization
If you don’t cluster queries or do it manually, you run the risk of creating several pages to cover one and the same topic. This leads to cannibalization, rankings dropping and make it tough to grasp what content a user really needs. Clustering helps to avoid keyword cannibalisation, create relevant content and enhance understanding of real keyword intent.
Find Gaps in Your Content
Clustering bares topics you lack. When phrases are grouped and distributed across URLs, it’s clear whether a topic is covered by your website or not and require a new landing page. Clusterization will find gaps in your content strategy and highlight where you lose traffic and can boost it with new pinpoint content.
Pearl Off Futile Phrases From The Start
Thundo checks search volume during clustering, so that you can prioritize clusters right after clusterization is over, quickly get rid of low‑volume keywords and refine the semantic core.

Clustering helps to understand which keywords have similar intent and should lead to the same page. The Keyword Clustering Tool groups queries based on Top‑10 search results: if the same URLs rank for different phrases, they are grouped into one cluster. Clustering allows you better understand search intent, identify areas for growth, avoid duplicating content and cannibalization and build a logical site structure. Clusters are convenient to use for content planning, building SEO‑strategy and internal linking.
Do I need to pre‑clean semantics before clustering?
Pre‑cleaning is optional. You can load the semantics as is, and Thundo will identify weak and irrelevant phrases by checking search volume and clustering itself. After clusterization, you can remove low‑frequency keywords manually or by filtering, and remove entire groups that you think may be irrelevant. This is especially useful when working with large semantic cores with hundreds of thousand of keywords.
Can I export clusters?
Yes, you can export keyword clusters in convenient formats (CSV, XLSX, Google Sheets) or collaborate online. This allows you to easily share data with your team. You also can export volume, rankings and ranked URLs.
How often does Thundo update volume?
The tool shows the current volume at the time of clustering. The data is collected when launched — you always get the exact keywords volume, with the ability to select a country or region. You also can check search volume manually at any time, without launching clustering.
How many keywords can I cluster at once?
You can cluster hundreds and thousands of search queries! The tool easily copes with large volumes of semantics — it is created to work with a full‑fledged large semantic core.
How does your tool differ from your competitors?
Thundo Keyword Clustering Tool combines Top‑10 clustering and volume; works with all the regions, locations, and languages, available in Google; as well as flexible clustering modes (Soft / Moderate / Hard methods) and levels. This is a powerful tool for creating SEO content clusters, which is suitable for both large agencies and freelancers.
Do you use NLP clustering like other tools?
No, our tool works differently. We do not use algorithms based on semantic proximity or natural language processing (NLP) to form cluster recommendations. Instead, Thundo buckets keywords based on real search results — by analyzing which pages rank for each query. If two keywords lead to the same URLs in SERP Top, it means that the search engine considers them relevant to the same topic. This approach gives a more accurate and practical grouping based on how Google interprets keywords, rather than on assumptions on similarities in the meaning.
