75% of users never scroll past the first page of search

  • Content Relevancy: With keyword clustering, your content is more likely to match the search intent and be relevant and valuable to your target audience, which can increase traffic, user engagement, and conversion rates.
  • Strategic SEO Planning: Grouping keywords with shared intent helps craft a content roadmap that targets numerous keywords for a topic instead of concentrating on single keywords.
  • Time-Saving: Manual keyword clustering is practically impossible on a large scale and time-consuming.

How to Choose the Best Keyword Clustering Tool

Choosing the best keyword clustering tool involves considering your budget, needs, and features. What works for others may not work for you.

  • Budget: Some offer free trials, while others have monthly or yearly subscriptions. It’s important to find a budget-friendly tool with the necessary features.
  • Features: Some tools have advanced clustering algorithms, superior reporting capabilities, or better integration with SEO platforms. Choose a tool that delivers the desired results.
  • Usability: A tool is only valuable if it’s easy to use. Avoid wasting time on complex interfaces. Opt for user-friendly tools with excellent customer support.
  • Integration: If you’re using other SEO tools, ensure whichever keyword organizer you pick will work alongside them.
