Google just dropped support of the &num=100 feature, confirmed by Search Engine Roundtable and our own observations of search engine’s behaviour.
The Google’s &num=100 parameter previously allowed us to return top-100 search engine results by default in Google Organic SERP API endpoints. However, now that this parameter is practically defunct, Google returns ten results on each SERP page by default in most cases.
Our development team has been running numerous tests to analyse the search behaviour and find the potential solution to this issue. So far, they’ve been able to confirm that for every 100 you specify in the num parameter, you’ll receive exactly 10 SERP results back. This means num=100 gives you 10 results.
These disruptive changes on Google’s end left us no choice but to move quickly with updates to our system.
Crucial Google SERP API Updates
To spare our customers from over-the-weekend disruptions and give them more time to adapt, we’re introducing an interim update today – with the main changes postponed to September 19, 2025.
Effective immediately:
➤ The default depth value for Google Organic SERP API endpoints is 10. If you do not specify the depth parameter in the request, the API will return ten results by default.
➤ If the depth parameter is specified in the request, we will keep charging for every 100 search engine results up until 19/09/2025.
Effective from September 19, 2025:
➤ Starting from 19/09/2025, users of Google Organic SERP API endpoint will be charged for every 10 search engine results. For example, a standard POST request with "depth": 10 will cost $0.0006. The cost of the same request with "depth": 100 will be equal to:
$0.0006 × 10 = $0.006
➤The default value of the depth parameter will remain 10 until further notice.
Please, review your current implementations to ensure optimal result counts.
