If a site experiences a traffic drop correlating with an update, use Search Console to compare performance before and after the update, focusing on top pages and queries. Assess the drop's size and analyze different search types separately. Large drops require a site-wide review for helpful, reliable, people-first content. Avoid quick fixes, prioritize user-focused improvements, and consider deleting content designed solely for search engines. Changes may take days to months to impact search rankings.\n"]]
