Keyword Tool review

Keyword Tool generates long-tail keyword ideas by scraping autocomplete suggestions from Google, YouTube, Bing, Amazon, Instagram and other platforms, rather than pulling from Google Keyword Planner like most competitors. The free version works without signup and returns up to 750+ suggestions per search term, per the homepage. It covers 190+ country domains and 120+ languages, which matters for anyone doing localized or multilingual keyword research.

The free tier shows keyword ideas only, no volume, CPC, or competition data. To see that metric layer, you need Keyword Tool Pro, which starts at $68/month billed annually (or $88/month billed monthly) on the Starter plan, according to the pricing page. Pro also adds API and MCP access across 17 platforms, daily request caps, and historical search data going back 12 to 48 months depending on the plan.

The core pitch holds up: because it scrapes autocomplete instead of Keyword Planner, it surfaces long-tail phrases that competitors sourcing from Keyword Planner won't show you. A commenter on r/PPC claims Keyword Tool Pro pulls up to 19 autocomplete suggestions per search term versus the 5-10 you'd see doing a manual Google search, adding up to 1,400+ long-tail keywords per the same thread.

Other things Reddit users point to as genuine strengths:

• The free version requires no account and is usable immediately, which multiple commenters on r/bigseo called "pretty awesome" for a no-cost tool
• The Questions feature, which surfaces question-based long-tail queries, got a specific shoutout in one r/bigseo thread
• Broad platform and language coverage makes it useful beyond plain Google SEO, including YouTube tag research, where one r/letsplay poster was pointed toward it before switching to TubeBuddy
• Reddit users treat it as a legitimate second opinion tool, often running it alongside KeywordShitter or Moz Keyword Explorer rather than instead of them

The free version's biggest limit is data, not keyword count: no search volume, CPC, or competition numbers at all, per the pricing page. You get a long list of phrases and have to guess which ones matter.

Pro pricing scales fast. Starter runs $68-88/month for just 50 requests/day and volume data capped at 50,000 keywords/day. Growth, Scale, and Agency tiers push the daily request cap to 100, 200, and 400 respectively, with Agency running $628-788/month. There's no published overage pricing; the pricing page notes daily pools simply stop working once exhausted. Enterprise pricing isn't published at all.

Reddit sentiment on Pro is mixed. One r/PPC commenter called it "way more expensive" than Long Tail Pro Platinum for similar functionality, and another said they kept gravitating back to SEMrush despite paying for Keyword Tool Pro. No free trial exists, only a 30-day money-back guarantee, so testing Pro means paying first and asking for a refund if it doesn't deliver.

The free version costs nothing and needs no signup, per the homepage. It generates 750+ long-tail suggestions pulled from Google, YouTube, Bing and Amazon autocomplete. The catch: no search volume, CPC, competition or trend data. For that, you need Keyword Tool Pro.

Pro starts at Starter, $68/month billed annually or $88/month billed monthly, for 50 requests/day and volume data on 50,000 keywords/day. Growth jumps to $148/month annual ($188 monthly) for 100 requests/day. Scale runs $308/month annual ($388 monthly) for 200 requests/day and 48 months of historical data. Agency tops out the published tiers at $628/month annual ($788 monthly) for 400 requests/day. Enterprise pricing isn't published.

There's no free trial of Pro, just a 30-day money-back guarantee. And once you burn through your daily request pool, the pricing page doesn't list any overage rate. You wait until tomorrow or upgrade.

Leaving the free version costs nothing because there's nothing to leave. No account, no stored project data, no lock-in. If a search term doesn't return what you need, you just close the tab and try SEMrush or Ahrefs instead.

Pro is a different story once you're paying for seat access across 17 platforms via web, MCP, or API. Switching providers means re-exporting keyword lists and rebuilding whatever workflow you piped through Keyword Tool's API.

Why people leave: Reddit threads comparing keyword tools consistently put Keyword Tool Pro behind SEMrush and Longtail Pro on value once you're paying for volume data. Commenters on r/SEO and r/bigseo note that the daily request caps feel restrictive at the Starter and Growth tiers, and that competitors bundle rank tracking or content tools for similar money. The lack of a free trial for Pro, just a money-back guarantee, also gets mentioned as a reason buyers test it cautiously before committing to annual billing.
