Everything you need to pick the right keywords
From idea generation to real metrics, intent and clustering, keyword research is built to turn a blank page into a ranked content plan.
Three ways to start
Begin from a seed keyword, a competitor URL, or by importing a list. Same depth of data whichever way you start.
Autocomplete expansion
Every seed is expanded through Google Autocomplete in two passes, surfacing the real long-tail questions people actually search.
Real search metrics
Search volume, CPC, competition and a 12-month trend pulled from Google Ads, so you prioritise genuine demand.
Search intent detection
Every keyword is tagged informational, navigational, commercial or transactional, so you build the right page type.
Keyword difficulty
A 0 to 100 difficulty score on every keyword, so you target terms you can realistically rank for.
Smart filters
Filter by include and exclude words, plus volume and difficulty ranges, to cut straight to the opportunities.
SERP analysis per keyword
Open the live SERP for any keyword to see who ranks, their authority and the SERP features in play.
Clustering and briefs
Group related keywords into topics with semantic or SERP-based clustering, then turn each cluster into a content brief.

Keyword research FAQ
Is the keyword research tool free?
Yes. You can generate hundreds of real long-tail keyword ideas for free with no signup using the tool above. Full keyword research with search volume, difficulty, intent and clustering runs on your account, and the free plan includes enough to research a real topic before you ever pay.
Where does the keyword data come from?
Keyword ideas come from Google Autocomplete, expanded in two passes. Search volume, CPC, competition and the 12-month trend come from Google Ads data, and SERP analysis reads the live Google results, so every number reflects real search demand.
How many keywords can I get per search?
Up to 5,000 keywords per job. You can start from a seed keyword, a competitor URL or an imported list, then filter by volume, difficulty, intent and include or exclude words.
What is keyword difficulty?
Keyword difficulty is a 0 to 100 score estimating how hard it is to rank on page one. Lower scores are easier wins. We band it into Easy (0 to 39), Medium (40 to 59) and Hard (60 to 100) so you can filter at a glance.
Can I research keywords from a competitor's URL?
Yes. Paste a competitor URL and OneClickSEO expands keywords around that page's topic, so you can find the terms your competitors are targeting and where the gaps are.
Does it group keywords into topics?
Yes. Keywords are clustered into topics using semantic similarity and shared SERP results, then each cluster can become a content brief, so you plan whole topics instead of one keyword at a time.
