SERP data providers say Google throttles goto links per results page, so some rank data may store Google redirect links in place of page URLs.
Google is restricting the speed at which anyone can follow (google.com/goto) redirects for search results on each page, as per DataForSEO and Serper. Both sell Google search result API access. Due to this restriction rank data provided by these services may contain Google redirect URLs instead of actual URLs.
According to DataForSEO, the restrictions mean that they have seen some of their request modes only resolving part of the destination URLs. Serper’s status page first noted the issue at 1:30 a.m. UTC on October 30. SerpApi, another seller of search data, also logged goto links for organic results on the same date. Neither DataForSEO nor Serper links to a Google announcement regarding the restriction and the statements below are from their websites.
DataForSEO stated in its November 2nd article that when you open multiple links from the same results page in rapid succession, Google will begin to throttle the redirect(s). Each link carries an identifier based on the results page it originated from.
When Google throttles your redirects, instead of sending your requests for resolution directly to the destination, Google will send back a page with a “Continue” button. That button will only become available after a waiting period. The amount of time the continue button is disabled grows the faster the previous links were resolved.
For example, take a results page that contains 18 goto links to other websites.
