Sharp search traffic losses were no more common than usual after Google’s March 2026 spam and core updates: 2.8% of websites in Diib’s data had a sharp drop in Google search visits in the two weeks after they began, within the 2.2\u20132.9% range of two-week stretches with no update.<\/p>\n\n\n\n

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

Google’s March 2026 spam update and core update overlapped, rolling out between March 24 and April 8, so we measured them together. We compared each website’s visits from unpaid Google search in the 14 days before (March 10\u201323) with the 14 days from March 24 (March 24\u2013April 6). We included 35,482 sites with complete daily data and at least 150 search visits in the two weeks before. 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 five update-free periods between April and early August.<\/p>\n\n\n\n

Period (start date)<\/th>Sites<\/th>Search visits down 30%+, direct steady<\/th><\/tr><\/thead>
March spam + core updates (Mar. 24)<\/strong><\/td>35,482<\/strong><\/td>2.8%<\/strong><\/td><\/tr>
Weeks with no update (5 periods)<\/td>34,543\u201335,702<\/td>2.2%\u20132.9%<\/td><\/tr>
September spam update (Sept. 24)<\/td>34,928<\/td>8.4%<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Did the March 2026 core update hit any industry harder?<\/h2>\n\n\n\n

Not in this data. The typical website kept 97% of its usual search visits, against 98\u2013102% in the update-free periods. Every industry with at least 800 sites stayed within about 1.2 points of its normal rate. Finance sites were highest at 4.1% (2.9% normally) and home and garden sites lowest at 1.7%.<\/p>\n\n\n\n

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

The sites that did drop mostly stayed down. Of the 993 with complete data six weeks on, 68% were still down by a quarter or more in days 29\u201342 after the start (April 21\u2013May 4), and only 16% were back within 10% of normal. The typical one had 63% of its usual search visits two weeks after the start and 64% six weeks after, matching the 2026 pattern in Diib’s look at recovery after 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 either update caused any single drop. Diib’s review of all seven 2026 updates<\/a>, which used a stricter test, reached the same conclusion for March. August’s spam update also looked close to normal (see the August 2026 data<\/a>).
