AnswerThePublic is a valuable tool for generating keyword ideas, but its $99/month price tag and limited keyword coverage limits its usability. Fortunately, there are several excellent alternatives available that offer more comprehensive features and often come at a lower cost.
Below, we explore the top alternatives to AnswerThePublic to find longtail keywords for any topic.
Glimpse

Glimpse is a Chrome extension that provides a few powerful features for keyword research and search trend analysis. It offers several key advantages over AnswerThePublic:
Superior keyword coverage: Glimpse provides a more extensive list of longtail keywords than AnswerThePublic to make sure you don't miss out on valuable search terms.
Real-time updates: Unlike AnswerThePublic, Glimpse updates its data hourly, giving you access to the latest trends and search queries.
Query segmentation: See the top questions people ask, which brands they reference, and attributes they use, including "X for/with/without/etc."
And more.

Keyword Tool
Keyword Tool is a robust alternative to AnswerThePublic. It offers growth metrics for longtail keywords, enabling you to effectively sort by month-over-month growth. However, it has some limitations compared to Glimpse—its free version restricts data access, and it can lack the finer-tuned keyword metrics available in more dedicated SEO tools.
