Setting Live ‘Keywords For Site’ Tasks
This endpoint will provide you with a list of keywords relevant to the specified URL along with their search volume for the last month, search volume trend for up to 24 past months (for estimating search volume dynamics), current cost-per-click and competition values for paid search. The maximum number of returned keywords is 3000.
If your system requires delivering instant results, the Live method is the best solution for you. Unlike the Standard method, this method doesn’t require making separate POST and GET requests to the corresponding endpoints.
If you don’t need to receive data in real-time, you can use the Standard method of data retrieval. This method requires making separate POST and GET requests, but it’s more affordable. Using this method you can retrieve the results after our system collects them.
