How It Works
Here's how you can use our keyword clustering tool in your SEO and content marketing process.
Keyword clustering is an advanced SEO technique that organizes related keywords into groups, or "clusters," based on shared search intent and semantic meaning.
Previously, clustering was done manually by checking SERPs and seeing which keywords returned the same results (with matching search intent). Now, tools using machine learning like Answer Socrates accurately cluster keywords into related keyword groups for you, in seconds.
By structuring your content around these clusters, you can create comprehensive pages that address an entire topic rather than creating thin content targeting keywords with the same intent, which don’t rank. This reduces keyword cannibalization, prevents duplicate or overlapping content, and helps you build topical authority, which is essential in ranking now in the age of AI search.
Instead of publishing ten separate posts that each target a single long-tail keyword, keyword clustering shows you which keywords fall into one authoritative article that ranks for dozens (or even hundreds) of relevant queries.
The result is leaner content production, stronger internal linking opportunities, better alignment with Google’s Helpful Content and EEAT guidelines, and significantly improved rankings across a wider set of terms.
1. Add your keyword or upload a CSV
We recommend using our free keyword generation tool first to generate hundreds of keywords for your topic, and export this as a CSV and then upload this here to group related keywords into topics. Or, you can add keywords in the box below and we’ll group these into related topics for you. If you have a keyword export from another tool like Ahrefs or Semrush, we can also cluster these for you if you upload the CSV.
2. Select which column in your CSV are your keywords
Select which column in your CSV contains the keywords you want to cluster into keyword groups.
3. Proceed with clustering
Click 'proceed' to see:
- The number of cluster credits available based on your current plan
- The number of credits that will be used for the current clustering task
4. Get your clustered keyword groups
In around 10 seconds, we’ll cluster all your keywords for you. At the top, we’ll show you the main topic groups we created, and if you scroll down, you’ll see each content group, and which keywords fall into group.
5. See each cluster’s search volume, CPC, and competitiveness level
Click on the icon in the top right of each cluster to see:
- The total search volume of all keywords within the group
- The average CPC across these keywords (high CPCs indicate high commercial value)
- The average competition across the keywords (low competition means it’s easier to rank for this keyword)
6. Export your clustered topics as a CSV
In the top right corner, select the option to download all your clustered topics. This will download a CSV containing every keyword group, with every keyword within it. This also includes all the search volume data for every keyword, as well as all the CPC and competition data.
This will generate a CSV output containing all the different cluster topics for your records.
7. Revisit your keyword clusters any time in the “Saved Searches” area
In the Answer Socrates sidebar you can see all your previous searches, including all your previous keyword clustering projects. These never expire - you have these forever. You can always redownload these if you lose your CSV file.
