Bing keyword research for any keyword: how often it is searched, by country and language, its history, or related keywords.

GEThttps://api.rankparse.com/v1/bing/keyword-researchFreeAPI key + connected Bing account

How often a keyword is searched on Bing, in a country and language. It is not tied to one of your websites. It is Bing data, not Google search volume, but it works when Google Ads volume is unavailable. Three views: impressions (searches in a date range), history (past months) and related (related keywords).

It calls Bing's GetKeyword, GetKeywordStats and GetRelatedKeywords. Bing's payload for this method is passed through with its keys in snake_case and its dates as ISO timestamps. The fields below are the ones Microsoft documents; anything else Bing adds appears as well.

Behavior and limits

Credits: 0. Counts toward the daily cap of 300 live Bing reads per workspace. It reads no website, so no site is needed.
Bing only: these are searches on Bing, a fraction of all searches. Use them to compare keywords, not as Google volume.
