Keyword Tool

The best keywords are often the long-tail ones the big expensive tools bury or miss entirely. Keyword Tool built its whole reputation on surfacing exactly those — 'a free keyword research tool that works 99.99% of the time and delivers long-tail keywords other tools hide from you.'

Mine what people actually search

Keyword Tool uses Google Autocomplete to generate hundreds of long-tail keyword suggestions for any term, pulling from the real queries people type into search. That autocomplete-based approach is powerful because it reflects genuine search behavior, not just a database's estimates — and it reliably surfaces the specific, lower-competition phrases that are often the easiest to actually rank for. It can produce 750+ suggestions in seconds, giving you a huge pool of ideas fast. It pairs naturally with tools like AnswerThePublic and Keywords Everywhere.

Way beyond Google

Keyword Tool works across 15+ platforms — YouTube, Amazon, Bing, Instagram, TikTok and Pinterest among them — so it's not just for web SEO. A YouTuber, an Amazon seller and a TikTok creator can all use it to find what their specific audience is searching for. With support for 190+ Google domains and 120+ languages, it's genuinely built for international and multi-platform research.

Free to start, no account needed

A big part of its appeal is accessibility: the core tool is free and doesn't even require creating an account, so you can pull keyword ideas in seconds with zero friction. The Pro version then adds the data that turns ideas into strategy — search volume, CPC, competition scores, historical trends, bulk uploads and API/MCP access for AI integration.

Reliable by design

The '99.99% of the time' framing reflects a focus on dependability — it consistently returns useful suggestions, which matters when keyword research is a routine part of your workflow.

Who it's for

Keyword Tool suits business owners, online marketers, content creators, SEO professionals, PPC advertisers and solo bloggers who need keyword research for content, SEO and paid campaigns.

Pricing

Keyword Tool is freemium: a completely free version gives you keyword suggestions with no account required, while the Pro subscription (tiered plans roughly $68–$788) adds volume, CPC, competition and trend data plus bulk and API access. You can get real value free before ever paying.

Bottom line: Keyword Tool is a fast, reliable, free way to uncover long-tail keywords from Google Autocomplete across 15+ platforms — surfacing the specific, winnable phrases that pricier tools often hide, with a Pro tier for full metrics.
