The report card
Best for free long-tail ideas from a dozen sites
Keyword.io is a free web tool that collects autocomplete suggestions from Google, Amazon, YouTube, eBay, TikTok and seven other sites, with no account needed to search. It shows suggestions only: no volume, CPC, difficulty or trend data. Amazon and some other sources are rate limited, and there's no API. You'll need a second tool to decide which ideas are worth writing about.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | Free outright, with no paid plan at all. Every source, saved lists, text export and the question generator cost $0. |
| Free plan and trial | A | Searches need no account, and lists need only a free one. The one limit: Amazon and some other sources are rate limited, while Google, YouTube, Bing and Wikipedia aren't. |
| Features | D | One narrow job: autocomplete suggestions from 12 sites, plus 20 question phrasings at a time. There's no search volume, CPC, difficulty or trend data, so you need another tool to choose between the ideas. |
| Ease of use | B | No rating on record. There's nothing to set up: type a word, pick a source, get a list. Searching needs no sign-up. |
| Platforms and integrations | C | Web only, with no integrations or API. Lists go out as text or to your clipboard. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Keyword.io is for
- Fits if you want a list of autocomplete ideas and don't need any numbers next to them
- Works for Amazon or eBay sellers who want the words shoppers type into those search boxes
Who it is not for
- Skip it if you need search volume, CPC, difficulty or trends, as it shows none of them
- Tight if you lean on Amazon suggestions, since that source and some others are rate limited
- Not for you if you want to scrape or resell the data, which its terms forbid without written permission
- Watch out: it's web only with no API, and lists leave only as text or through the clipboard
- Watch out: saving lists needs a free account, even though searching doesn't
Good to know
Good for
- Quick long-tail brainstorming at no cost
- Comparing what people type on Amazon, YouTube and eBay against Google
- Building keyword lists to paste into another tool for volumes
Worth knowing
- It shows no search volume, CPC, difficulty or trend data; the results are autocomplete suggestions only.
- Amazon and some other sources are rate limited, so heavy use stalls on those.
- Its terms forbid automated scraping and reselling the data without written permission.
