SEO glossary
What is keyword difficulty?
Keyword difficulty (KD) is a score, usually from 0 to 100, that estimates how hard it would be to rank in Google’s top 10 for a keyword. Higher means harder. SEO tools calculate it from the pages that currently rank, most often from how many and how strong their backlinks are. It is a third-party estimate, not a Google metric.
Related SEO terms
Search volume is the estimated number of times a keyword is searched per month in a given location, usually averaged over the past 12 months.
Traffic potential estimates the total organic traffic you could get by ranking first for a topic, counting every related query the top page ranks for.
Search intent is the reason behind a search: what the person wants to know, find or do. Matching it is one of the most important parts of SEO.
Cost per click (CPC) is what advertisers pay for one click on a search ad. In SEO, a keyword’s CPC hints at how commercially valuable it is.
Keyword research is finding the search terms your audience uses, then judging which ones are worth targeting by demand, difficulty and intent.
Keyword overview FAQ
Where does traffic potential come from?
It is the organic traffic the top-ranking page gets from all the keywords it ranks for, when that is known. Otherwise it is estimated from this keyword alone: its volume times a typical click-through rate for the first result.
Why does a keyword show a clickstream estimate?
Google Ads reports no volume for some topics, such as VPNs or gambling. For those, the overview uses a volume estimate from clickstream data instead, and says so.
Do I need a project?
No. The SEO tools work on their own, in any market you pick. Keywords you find can be saved to a project in one click when you want to track them.
Can I share a result?
Yes. The search, the market and the open tab are all in the page address, so a link or a bookmark opens the same view. Anyone opening it runs the search with their own key; a repeat of something already looked up is served from the cache for free.
