Why it matters for founders and small teams
Head terms belong to brands with years of links, but the specific questions your buyers ask — with their team size, budget and stack attached — often have no page written for them at all. Long-tail keywords are where a small team can win now, and they’re also the closest thing classic SEO has to the full-sentence prompts buyers type into ChatGPT.
Do long-tail keywords make up most searches?#
Long-tail keywords make up the vast majority of distinct searches — about 93% of keywords in Ahrefs’ US database get fewer than 10 searches a month, and roughly 15% of Google searches each day are brand new — though keyword tools, which count volume phrase by phrase, show most measured volume sitting in head terms.
~93%
of keywords in Ahrefs' US database get fewer than 10 searches a month
15%
of the queries Google processes each day have never been searched before
3.3%
of measured search volume came from keywords with 1–100 monthly searches, though they were 91.8% of keywords
Both pictures are true at once. Each long-tail phrase is tiny, head terms carry most of the volume that tools can measure, and the tail is so long and so new that no database lists it all. The practical reading: don’t size an opportunity by one phrase’s volume. A page that fully answers one specific question tends to rank for many related phrasings — what Ahrefs calls supporting long-tail keywords.
Length isn’t the definition, either. Ahrefs points out that some one-word keywords get under 100 searches a month while some five-word keywords get hundreds of thousands. The tail is about low demand and high specificity.
How are long-tail keywords different in AI search?#
In AI search the long tail gets longer and harder to measure: people type full questions with context into ChatGPT and AI Mode, most of those prompts match no keyword in any database, and the engine then turns each prompt into narrower sub-searches of its own.
65–85%
of ChatGPT prompts couldn't be matched to any keyword in a 27-billion-keyword database
8.7
words on average in ChatGPT prompts that triggered a search in early 2026, up from 4.7 a year earlier
53% vs 8%
of Google searches with 10+ words produced an AI summary, against one- or two-word searches
Ahrefs calls these conversational long-tail keywords and estimates that over 95% have no measurable search volume — “not because nobody is searching, but because everybody is searching differently.” Google’s AI features guide makes the same point from the other side: AI systems understand synonyms and meaning, so “you don’t have to worry that you don’t have enough ‘long-tail’ keywords or haven’t captured every variation of how someone might seek content like yours.”
The target shifts from phrasings to questions. Long-tail keywords are what people type; query fan-out searches are what the engine types on their behalf — and both reward one clear page per specific question.
Worked example
The Long-Tail Demand Stack
A way to compare one head term with a stack of long-tail questions for the same product. Every figure below is illustrative, for Plannora, a fictional project management tool — swap in your own volume and difficulty numbers.
- 1
The head term
“project management software”: big volume, but the top 10 belongs to category leaders with years of links. Keyword difficulty 90 out of 100.
40,000/mo
- 2
Plannora's realistic share of it
Assume a young site won’t reach page one for that term this year, and plan on no clicks from it.
≈ 0 clicks
- 3
Twenty-five long-tail questions
“project management for a 5-person design agency”, “how to track client approvals”, “Plannora vs Trello for freelancers” and 22 more, each 40–300 searches a month.
3,200/mo
- 4
The winnable ones
Low difficulty and no strong page answering them yet: 15 of the 25.
1,900/mo
- =
Clicks at an assumed 10% click share
If each page earns about a tenth of its query’s searches — an assumption for the example, not a benchmark — the stack sends roughly 190 visits a month, before counting the related phrasings each page also ranks for.
≈ 190/mo
The result: 190 specific visits beat zero generic ones, and the real total is likely higher: tools miss most conversational phrasings, and each of the 15 pages is also a candidate answer for the sub-questions AI engines search. Build the long tail first, and revisit the head term once the cluster has earned links.

How do you find long-tail keywords?#
Find long-tail keywords where buyers phrase their problems — Google’s autocomplete and People also ask, sales and support conversations, forums and Reddit threads, and the prompts buyers put to AI assistants — then group phrasings that share one intent into a single page.
- Start from the buyer’s situation, not a seed keyword: their role, team size, stack and the job they’re stuck on.
- Mine the questions you already hear. Sales calls, demo notes and support tickets are long-tail lists no competitor can export.
- Harvest Google’s suggestions: autocomplete, People also ask and related searches for each core question.
- Read the threads. Reddit and niche forums show the exact wording buyers use, and often which answers they found missing.
- Ask the AI assistants your buyers use, and note the follow-up questions and searches they show.
- Group by search intent before writing. Phrasings a searcher would expect answered on one page belong together; a question that needs its own answer gets its own page in a topic cluster.
Common mistakes with long-tail keywords#
The most common long-tail mistakes are dismissing queries because a tool shows zero volume, defining the long tail by word count instead of demand, and publishing a thin page for every variation instead of one strong page per intent.
Myth
Zero volume in a keyword tool means zero demand.
Reality
Tools can’t see brand-new or conversational queries. Around 15% of Google’s daily searches are new, and most AI prompts match no keyword at all.
Myth
Long-tail means long.
Reality
Some one-word keywords are long-tail and some five-word ones are head terms. Judge by demand and specificity, not word count.
Myth
Every variation needs its own page.
Reality
Google says its AI systems understand synonyms, and mass-producing variants risks its spam policy. One page per intent, answered fully, covers the variations.
Myth
Long-tail traffic is too small to matter.
Reality
Ahrefs notes long-tail queries often convert better because they’re more specific, and one page can rank for dozens of related phrasings. Use keyword difficulty to find the winnable ones, then stack them.
