2How many people visited
In plain words: These sites got fewer visits from Google than a year ago (-28%), and October 2026 was a weaker month than September 2026 (-8%). Grammarly, which takes 89.8% of all the visits, fell in line with the market (-29% on a year ago). Grammarly made most of the move in October 2026: it lost 1,803,551 of the market's 2,224,979 visits; without it, visits to the other sites fell 14.5% on September 2026.

Miles explains
Judge this line on the year, not the last dot: visits are 28% below a year ago, and 36% below the January 2026 high. One site winning or losing a ranking can swing a single month a lot.
3How many people went looking
People typed a site’s name into Google 33% less often than in October 2025 (-33%). That is the loyalty number: nobody types a name by accident.

US searches a month for the counted brand names, summed. Google Ads data via DataForSEO, to September 2026.
Miles explains
Name searches are the number I trust most. They are down 33%, and nobody types a site’s name by accident, so this shows fewer people coming back on purpose.
4Where the visitors live
About 23 of every 100 visits come from the United States. Outside the US I measure 7 countries one by one; the largest is India.
