Keyword.io

Keyword.io is a free keyword research tool that gathers long-tail suggestions from many sources, including Google, Amazon, YouTube, Bing, TikTok, eBay, Wikipedia and DuckDuckGo. Results come back instantly from autocomplete data, and users can save keywords to lists and export them as text files. Some platforms are rate limited, while Google, YouTube, Bing and Wikipedia run without limits. Companion free tools include Bing and eBay autosuggest generators and a question and intent generator. Keyword lists can be organized under an account, and the same suggestions can be reused for AI content ideas or fed to ChatGPT, Claude and other language models. It is pitched to SEO professionals, content creators and marketers who want ideas for articles, video topics or paid campaigns. Using it costs nothing and needs no credit card.
