Sharp search traffic losses were no more common than usual after Google’s March 2025 core update: 2.4% of websites in Diib’s data had a sharp drop in Google search visits in the two weeks after it began, within the 2.0\u20133.2% seen in most two-week stretches with no update.<\/p>\n\n\n\n

What Diib measured<\/h2>\n\n\n\n

Google’s March 2025 core update rolled out from March 13 to March 27, 2025. We compared each website’s visits from unpaid Google search in the 14 days before (Feb. 27\u2013March 12) with the 14 days from March 13 (March 13\u201326). We included 33,837 sites with complete daily data and at least 150 search visits beforehand. A site counted as a drop if its search visits fell 30% or more while its direct visits (people typing the address or using a bookmark) held within 30% of normal, which filters out tracking problems and outages. As a baseline, we ran the same test on 11 update-free periods between January and June 2025.<\/p>\n\n\n\n

February’s update-free periods ran higher for reasons this data can’t explain. March’s rate was lower than those weeks, not higher.<\/p>\n\n\n\n

Did the March 2025 core update hit any industry harder?<\/h2>\n\n\n\n

Not in this data. The typical website kept 101% of its usual search visits, against 92\u2013107% in the update-free periods. No industry with at least 800 sites ran more than about a point above its normal rate. Finance sites were highest at 3.7% (2.6% normally), and home and garden sites were among the lowest at 1.3% (2.3% normally).<\/p>\n\n\n\n

Six weeks later<\/h2>\n\n\n\n

The sites that did drop mostly stayed down. Of the 809 with complete data, 73% were still down by a quarter or more in days 29\u201342 after the start (April 10\u201323), and 15% were back within 10% of normal. Drops in update-free periods stuck about as often (61\u201376% still down), the same pattern as in Diib’s look at recovery after 2026 Google updates<\/a>.<\/p>\n\n\n\n

What this data can’t tell you<\/h2>\n\n\n\n

Core updates can move rankings for many pages by smaller amounts that a 30% test won’t catch, and timing alone doesn’t prove the update caused any single drop. The March 2026 core update<\/a> looked much the same.
