Common questions about Optiwing's keyword grouping and clustering tool.
Is the Optiwing keyword grouping tool free?
Yes, you can start for free. Every account comes with 100 free credits and no credit card is required, so you can group your first batch of keywords at no cost. After that, the keyword grouper uses pay-as-you-go pricing from $4.42 per 1000 keywords with no subscription.
Is this a keyword clustering tool or a keyword grouping tool?
Both terms describe the same thing. Keyword grouping and keyword clustering both mean organizing related keywords into clusters that share search intent. Optiwing works as a keyword clustering tool and grouping software in one, building clusters automatically from live Google SERP data.
How does the keyword grouper tool actually group keywords?
Optiwing searches each keyword on Google and compares the top 10 ranking URLs. If two keywords share 3 or more of the same top 10 results, they share the same search intent and are grouped into the same cluster. This SERP-based method is more accurate than grouping by shared words alone.
How is Optiwing different from Keyword Grouper Pro and other free keyword groupers?
Most free desktop keyword groupers, including tools like Keyword Grouper Pro, cluster keywords lexically by matching shared words or phrases. Optiwing groups by actual Google SERP overlap, so clusters reflect real search intent rather than just similar wording. It also runs in your browser with no download, handles thousands of keywords, and lets you set location, device, and language.
Can it handle bulk keyword grouping for thousands of keywords?
Yes. Optiwing is built for bulk keyword grouping. Upload a CSV of thousands of keywords exported from Ahrefs, SEMrush, Google Keyword Planner, or your own list, and the tool clusters them all automatically, typically within minutes.
What is keyword grouping software used for in SEO?
Keyword grouping software helps you avoid keyword cannibalization, build content silos, and decide which keywords to target on the same page versus separate pages. By clustering keywords by intent, you can plan one comprehensive article per cluster and build topical authority more efficiently.
