Independent analyses suggest Google’s AI search strategy is indeed having an impact. Search impressions—the number of advertiser links that show up in searches, even if they aren’t clicked—grew by 49% in the year since the overviews were launched, according to a May report from BrightEdge, a search-engine-optimization firm.

Wednesday’s report follows Alphabet’s better-than-expected Q1 release earlier this year, in which the company reported year-over-year growth of 12% and 49% for its top and bottom lines, respectively, after Google’s search unit generated more in sales than analysts projected.

The search giant predicted a further capital spending boost next year and cited massive demand for its cloud computing services.
