Get ‘Google AdWords Keywords For Keywords’ Results by id
Google AdWords Keywords Data API is a legacy version that is replaced by Google Ads API. If you’re using DataForSEO Google AdWords API, you need to migrate to DataForSEO Google Ads API.
This endpoint will select relevant keywords for the specified terms. Set up to 200 keywords and get the results, which are suggested by Google Ads for your query.
Note that Google AdWords API results might differ from the estimates you see in the Keyword Planner tool. Google provides account-specific results based on ad history, creatives already in the account, and other factors. The data provided by the API and in the UI might come from different sources.
