Yes, they've had a major update around the end of March that major penalized some of my sites and took impressions and clicks down to 0. About a month later around the end of April my sites recovered and traffic picked back up again:
The Google March 2025 Core Update was a broad algorithm update that rolled out from March 13th to March 27th, 2025. This update, like other core updates, aimed to improve the overall quality of Google's search results by better surfacing helpful, relevant, and satisfying content. It wasn't designed to target specific websites but rather to boost pages that were previously under-rewarded.
Then around May 20th it happened again and almost 0 traffic since then.
A significant Google SEO update, often referred to as the May 2025 Core Update, focused on improving content quality and relevance. This update, rolled out in early May, likely emphasized rewarding high-quality, in-depth content while penalizing AI-generated fluff and thin content. It also prioritized user intent and mobile-first performance.
