What keyword difficulty
Difficulty says how strong the pages already ranking are. Read it next to volume and the AI layer before you pick a target.
Difficulty from 0 to 100
A score from the strength of the pages in Google's top ten. Under 30 a new page can rank with good content; from 60 you compete with sites that have years of links.
Volume and cost per click
Average monthly searches in the market you pick, and what advertisers pay per click: a quick read on how much the search is worth.
The AI Overview mark
Whether Google answers the search with an AI Overview. Where it does, fewer people click the links, and being cited in the overview matters as much as ranking.

How is keyword difficulty calculated?
From the authority of the pages ranking in Google's top ten for the search, on a scale of 0 to 100. It estimates how hard it is to get a new page into that top ten.
What difficulty should I target?
A newer site does best under 30. With a few strong pages on the topic, 30 to 60 is reachable. Above 60 usually needs links and a site the topic already trusts.
Why does a keyword show no data?
It is searched too rarely in that market to measure, or is new. Try a broader phrasing or another market.
Why does the AI Overview mark matter?
A search with an AI Overview sends fewer clicks to the links below it. The same volume is worth less, unless your page is one of the sources the overview cites.
How many checks can I run?
A few a day, with up to ten keywords each, to keep it free. Keywords someone already checked this month cost nothing to read again.
