TL;DR Summary of Google Testing Removal of 100 Search Results Per Page Feature

Google Search is reportedly testing the removal of the option to view 100 results per page. The &num=100 URL parameter works inconsistently, suggesting a live experiment. This change may affect rank tracking tools and trigger random captchas due to new anti-bot measures.

Background on the 100 Results Parameter

Google Search users have long had the ability to customize how many results appear on a single page via the &num=100 parameter in the URL. However, recent observations indicate that this feature is now functioning unpredictably.

Evidence of a Testing Phase

  • The &num=100 parameter works intermittently—about 50% of the time according to reports.
  • Behavior varies depending on whether the user is signed in or out of Google accounts.
  • Some users experience the parameter functioning, while others do not, even within the same IP address.

Implications for SEO and Rank Tracking

These inconsistencies suggest Google is experimenting with limiting or removing the option to display 100 results per page. This has tangible effects on SEO professionals:

  • Rank tracking tools may return incomplete data or break due to changes in result page structure.
  • Increased captcha challenges and anti-bot detections have been reported, complicating automated data retrieval.
  • SEO analysts should monitor and adjust their tools accordingly to maintain accurate tracking.

Conclusion

While not yet confirmed as a permanent change, Google’s trial of restricting large result sets per page signals a shift that could impact SEO workflows and data collection methods. Staying informed and flexible will be key for search professionals navigating this evolving landscape.
