Frequently asked questions
Is the keyword difficulty checker accurate?
It uses live SERP data and the same math as the paid tool. Absolute scores are directionally reliable; use them for ranking triage, not as gospel.
What is a good keyword difficulty score for a new site?
Target KD under 30. Sites with Authority Score below 30 rarely break page 1 on anything harder without months of link building. KD 30-50 becomes reachable once you clear AS 40.
How is keyword difficulty calculated?
LemRank blends the median Authority Score of the top-10 ranking domains, backlink profile depth, on-page optimisation strength, and SERP feature density into a single 0-100 score.
Is there a free keyword difficulty checker?
Yes — the LemRank KD Checker is free, no signup required. Bulk CSV checking and historical KD tracking unlock on the free account tier.
How is this different from Ahrefs / Semrush KD?
Similar model, different data source. LemRank pulls from a 12-source cache and the live SERP; other tools rely on their own crawl and click-modelling data. Numbers will differ ±5-10 points typically.
Can I check multiple keywords at once?
The public tool accepts one query per submit. Sign up free to bulk-check hundreds via CSV upload.
