Estimate how hard a keyword is to rank for
This tool scores a keyword against the page one competition currently sitting in Google, giving you a quick read on whether it's worth targeting before you commit time to content or outreach. It works from live SERP signals, so the same keyword can score differently from one week to the next as the results change. Treat the number as a starting point for judgement, because no difficulty score, free or paid, can account for everything Google weighs.
What a keyword difficulty score actually tells you
Keyword difficulty is an estimate of how hard it would be to rank on page one for a given search term, based on signals like the backlink profiles and content strength of the pages currently occupying those positions. This tool turns that estimate into a single score, so you can sort a list of keywords by likely effort before you commit time to writing for any of them.
How the score is worked out
The estimator looks at the pages currently ranking for your term and weighs things such as domain authority, the number of referring domains, and how closely those pages match the intent behind the query. A high score means the existing results are backed by strong backlink profiles and well-built content, so outranking them will take real work: better content, more links, or both.
A low score doesn't guarantee an easy win. It usually means the competing pages are weaker on the signals the tool can measure, but it says nothing about how much content already exists on the topic elsewhere, or how well a page needs to answer the query to satisfy a searcher.
What the score can't tell you
Difficulty scores are built from measurable signals, not from the parts of ranking that are more judgement than arithmetic: how well the content actually answers the question, whether it beats what's already ranking, and how a search engine weighs factors that shift over time. Treat the number as a way to prioritise a list. Like any automated estimate, it can be wrong, particularly on competitive terms or in niches where rankings move often.
When this tool is enough, and when it isn't
A quick check like this suits the early stage of planning: you have a shortlist and want a rough sort before deciding where to spend time. For ongoing keyword research across a full content plan, or where you need difficulty sitting alongside search volume and click-through estimates from a larger index, a dedicated keyword research tool will get you further. See how the main options compare on keyword research tools compared. If you also want to know what a searcher is trying to do, pair this score with the keyword intent classifier.
For a longer look at how difficulty scoring works and the situations where it tends to mislead people, the guide to this tool covers the mechanics in more depth.
Keyword Difficulty Estimator
Type a keyword or phrase and pick a market. The tool looks at patterns in the text itself, word count, commercial or transactional words, question form, brand mentions, year and location qualifiers, and gives a rough difficulty band with the reasoning shown. It also guesses the search intent and suggests some long-tail variants to research. This is a heuristic estimate, not live search data.

What this tool cannot see: it runs entirely in your browser, with no server, no API and no external data. It has no access to live search results, real search volume, current rankings, your competitors, or your own site's authority. Every result above is inferred purely from the wording you typed.
What to check by hand: search the phrase yourself and see who currently ranks, run it through a keyword tool that uses real search volume and competition data, and compare your own domain's authority against the sites already ranking on page one.
