Quick answer: Since around September 13, 2026, Google appears to have significantly improved its ability to block AI scrapers, third-party search scrapers, and tracking tools that pull SERP data, according to reports from SEOs this week. The timing coincides with other recent algorithm-level changes.
What happened
Multiple SEO tool providers and analysts noted increased blocking, CAPTCHA challenges, and failed requests when scraping Google Search results starting around September 13. The tightened enforcement affects both dedicated AI-training scrapers and the third-party rank-tracking tools many SEOs rely on for daily SERP monitoring.
Why it matters
Rank-tracking and SERP-monitoring tools that depend on scraping may see gaps, delays, or reduced accuracy in their data during this period. This tightening also follows Google’s rollout of google.com/goto redirects, another change explicitly framed around preventing abuse of search result links — together, the two moves suggest a broader push to control how search result data and links are accessed by automated systems.
It’s also a useful data point alongside this week’s report that AI agents were used to breach real company systems — as AI-driven automation becomes both a bigger threat and a bigger nuisance, platforms are visibly hardening their defenses.

Is this related to a confirmed algorithm update?
