The query mode Application Programming Interface (API) in ASEOPS is the one you should preferably use to query search engines. Therefore, please set the mode in the Ranking Query section to Engine API.
Then click Add engine. In the list you will find all search engines which already support this query method. Currently these are Google, Yahoo and Bing. Other search engines will follow soon.
Via Edit engine you can apply any changes to an existing search engine, for example regarding the language or region.
Then click Start query to start the ranking query.
