How this long-tail keyword tool works
LongTailLab queries the public autocomplete services of six search engines at once, exactly like the suggestion dropdown you see when typing in Google. Every suggestion is a phrase that real people have actually searched for, which is why autocomplete remains one of the most honest sources of long-tail keyword ideas for SEO, blogging, YouTube and PPC campaigns. You enter a broad seed keyword — for example protein powder — and the tool systematically combines it with question words, prepositions and every letter of the alphabet, collecting every variation the engines return. Nothing is invented, nothing is estimated: what you see is what the engines themselves suggest.
- Type a seed keyword. Keep it short and broad — one or two words work best.
- Pick engines and modes. Questions and Alphabet soup modes multiply your long-tail harvest.
- Export and validate. Copy or export to CSV, then check volumes for your shortlist in Google Keyword Planner.
Why LongTailLab beats the freemium alternatives
Unlimited, not “3 per day”
Ubersuggest’s free plan is capped at three searches per day. SEMrush gives you ten reports a day behind a sign-up wall. Keywords Everywhere became a paid credit system. LongTailLab has no daily cap, no credit system and no account — the tool is free because it is light, not because it is crippled.
Six engines in one pass
Most free generators only scrape Google. Comparing Google, YouTube, Bing, DuckDuckGo, Wikipedia and Amazon suggestions in a single run surfaces buyer-intent and content-intent phrases that a single engine never shows.
Free CSV export, no lock-in
Many competitors let you see keywords but paywall the export. Here, selection, copy and CSV download cost nothing and always will. Your keyword lists belong to you.
Fast pages, zero popups
No modal newsletters, no cookie walls, no chat widgets. The page is a few kilobytes of HTML, CSS and vanilla JavaScript, which keeps Core Web Vitals green — a ranking factor your tools site will benefit from too.
Frequently asked questions
Is LongTailLab really free and unlimited?
Yes. There is no daily cap, no credit system and no paid tier. Unlike Ubersuggest (3 searches per day on its free plan) you can run as many seed keywords as you want, as often as you want.
Do I need to create an account or log in?
No account, no email, no cookie wall. Open the page, type a seed keyword and export. That is the whole flow.
Where do the keyword suggestions come from?
Directly from the public autocomplete (suggest) services of Google, YouTube, Bing, DuckDuckGo, Wikipedia and Amazon. These are real phrases real people type, which makes them excellent long-tail seeds for SEO and PPC.
Does it show search volume or keyword difficulty?
Autocomplete APIs do not expose volume, and we refuse to show made-up numbers. Use LongTailLab to harvest phrases, then validate the shortlist in Google Keyword Planner (free with a Google Ads account).
Can I export the keywords to a CSV file?
Yes. Select the keywords you like (or select all) and click Export CSV or Copy. Both are free and unlimited — no locked export like most competitors.
What are the Question and Alphabet modes?
Question mode prepends words like how, what, why, where and when to your seed to surface question keywords. Alphabet mode appends every letter a–z to your seed (the classic alphabet soup technique) to surface long-tail variations most tools miss.
Does it work on mobile?
Yes, the interface is fully responsive and the page weighs almost nothing, so it loads fast even on slow connections.
Do you store my keywords?
No. Everything runs in your browser. Nothing you type is saved, profiled or resold.
