Long-Tail Keyword Finder: Google, YouTube, Amazon, Bing

One seed keyword in, hundreds of real long-tail phrases out. Read from the autocomplete of Google, YouTube, Bing, DuckDuckGo, Amazon and eBay at the same time, deduplicated into one table.

No API key, no account, no proxy.

What does this do?

Autocomplete is the only free, first-hand record of what people actually type. Every other keyword Actor reads one box — usually Google — and hands back a list. This one reads six, merges them, and tells you which platforms agreed.

Who is it for?

You are	You use it to
SEO and content writers	Build a topic cluster from the questions people really ask
YouTubers	See what the YouTube box suggests, which is rarely what Google suggests
Amazon and eBay sellers	Find the buying phrases shoppers type in the marketplace, per country
PPC managers	Harvest long-tail phrases and negative keyword candidates
App and product marketers	Find the words your market uses before you write the page
Agencies	Produce a keyword universe for a client brief in under a minute

What data do you get?

One row per keyword:

Field	Meaning
keyword, seed	The phrase, and the seed it came from
platforms, platformCount	Which boxes suggested it, and how many
bestRank	The highest position any platform gave it
timesSuggested	How many different queries surfaced it
score	Ranking signal: breadth, repetition and position combined
intent	question, comparison, local, commercial or general
wordCount, characterCount, isLongTail	Shape of the phrase (long tail is 4+ words)
containsSeed	Whether the seed survived, or autocomplete drifted to a neighbour

The run summary adds per-platform and per-intent totals, the top keywords and the top questions for each seed.

Example: three seeds, one run

A real run on 17 September 2026 from Apify, US market, 40 seconds, 4,089 keywords:

Seed	Keywords	Google	YouTube	Bing	DuckDuckGo	Amazon	eBay	Questions
running shoes	1,500	556	446	533	460	298	192	233
protein powder	1,500	587	528	596	484	354	160	231
project management software	1,089	445	313	488	327	7	0	117

That last row is the point of reading six boxes: a software term has no shopping demand at all, while "running shoes" has 490 marketplace phrases that Google never shows you.

What this does not give you, and why

There is no search volume and no cost per click. Those numbers come from Google Ads, which needs a paid account and an API key, and this Actor is built to run with neither. Anything else you see sold as "free search volume" is a scrape of somebody's dashboard and breaks when they change it.

Instead you get three honest popularity signals straight from the source:

• platformCount — six boxes suggesting the same phrase is a strong signal
• bestRank — autocomplete lists are ordered by popularity, so position 1 means something
• timesSuggested — how many different queries pulled it back

Also worth knowing: the country behind Google, YouTube, DuckDuckGo and Bing follows the server, which is in the United States. You can pick the language, and the shopping market setting really does switch Amazon, eBay and Bing to another country, but "Google suggestions as seen from Germany" is not something this can promise.

How to use it

1. Put your seed keywords in, one per line. Short seeds return more.
2. Choose the platforms. Drop Amazon and eBay for services and software; keep them for anything physical.
3. Choose the expansions: letters a-z, question words, buying words, prepositions.
4. Set the language and, for the shopping platforms, the market.
5. Run it. One seed with all six platforms is about 450 requests and takes 5 to 25 seconds.
