Yeap, I did an extensive search even using some Google advanced search operators and couldn´t find anything.
But, I think my method should be pretty close to what you saw.
Another way I can think of how you can find KGR keywords with Ahrefs is to...
- Run a competitor´s URL on Site Explorer
- Go into the organic keywords tab
- Set the volume to a max of 250
- Set the word count to something like 4 or 5 - Something high so it won´t have too much competition (low allintitle result)
Also, forgot to mention, if you want to target a particular user´s search intent you can filter down keywords by using the "Include" tab and add prefixes like...
- "Best" - For commercial intent keywords
- "Best, For" and selecting "All Words" - For commercial intent keywords (this are very effective)
- "How to" - For informational intent keywords
- "Top" - Also, commercial intent.
You can also play with https://nichehacks.com/buyer-keywords-list/. I am sure you won´t have any issues finding great keywords with this.
