Get monthly search volumes, keyword difficulty, and related keywords — no Google Ads account required. Clean interface, instant results, built for SEO (not PPC).
Google Keyword Planner shows broad ranges unless you run active ad campaigns. KeySEO shows a specific monthly estimate for free — no ads, no spend, no account setup.
Google's tool is designed for advertisers managing bids and budgets. KeySEO focuses purely on organic search data: volume, difficulty, trends, and related keywords.
Google doesn't tell you how hard it is to rank. KeySEO calculates difficulty (0-100) based on domain authority, backlinks, and content quality of ranking pages.
No waiting for Google Ads interface to load. Enter a keyword, get data in 2-3 seconds. Simple, fast, distraction-free.
No ad groups, bid strategies, quality scores, or other PPC clutter. Just the data you need for content strategy — nothing more, nothing less.
Ahrefs ($129/mo) and SEMrush ($139/mo) are overkill if you only need keyword data. KeySEO gives you volume, CPC and difficulty free, one keyword at a time.

* Google Keyword Planner is free but requires a Google Ads account and shows exact volumes only when running active campaigns.
You need quick keyword data for blog posts. Google Keyword Planner's vague ranges ('1K-10K') aren't helpful. KeySEO shows a specific monthly estimate so you can judge whether '2,900 searches/month' is worth writing about.
Pain with GKP: Tired of Google forcing you to run ads just to see more than a range.
Clients ask for keyword research but you can't justify $129/mo Ahrefs for occasional projects. KeySEO gives you professional data free, and a $29 one-time report per client topic — no subscription to carry between projects.
Pain with GKP: Need quality data without enterprise pricing.
You're optimizing your own website and don't need backlink analysis or rank tracking — just keyword volumes and difficulty. KeySEO strips away the noise and gives you what matters.
Pain with GKP: Overwhelmed by complex SEO platforms with features you'll never use.
Finding product niches or validating demand. You need quick search volume checks for dozens of product keywords daily. KeySEO's free tool handles the spot checks, and a $29 report maps a whole niche at once.
Pain with GKP: Google Keyword Planner groups data for ad targeting, not precise product research.
No signup, no credit card. Just enter a keyword and see the data. Compare it to what Google Keyword Planner shows you (often just a range).
Search for your most important keywords in both tools. You'll notice KeySEO gives you a specific estimate (e.g., 5,400/month) plus difficulty scores, while Google gives ranges ('1K-10K') and no difficulty data.
If 5 searches/day is enough, stick with free forever. When you need a whole topic researched rather than single keywords, the AI Research Agent does it for a one-time $29 — no subscription.
If you're running Google Ads campaigns, keep using Keyword Planner for ad group planning and bid estimates. Use KeySEO for organic SEO research. They complement each other — one for ads, one for content.
