North Bay
The North Bay covers Marin and Sonoma Counties plus Napa and Solano. Bay Area AEO describes it as a mix of tourist destinations and close-knit local markets: wine country, Marin's small towns and Solano's growing cities. Its North Bay city pages are Santa Rosa, Petaluma, Rohnert Park, Vallejo, Fairfield, Vacaville, Suisun City, San Rafael, Novato and Napa. In Santa Rosa, visitors ask AI about breweries and wine tasting while residents ask for roofers and insurance agents.
South Bay
The South Bay is Santa Clara County, and the agency notes that a lot of the AI tools now recommending local businesses were built here. Its residents were early adopters, and many ask an assistant before they search Google. The city pages are San Jose, Sunnyvale, Santa Clara, Mountain View, Milpitas, Palo Alto, Gilroy, Cupertino, Morgan Hill and Campbell. In San Jose the agency's sample questions run from pho near Story Road to an emergency plumber in Almaden Valley.
East Bay
Alameda and Contra Costa Counties make up the East Bay, which the agency calls the Bay Area's largest and most varied market, from Oakland's food scene to the Tri-Valley suburbs and the Delta. It has seventeen city pages: Oakland, Fremont, Hayward, Berkeley, San Leandro, Livermore, Alameda, Pleasanton, Dublin, Union City, Concord, Antioch, Richmond, San Ramon, Pittsburg, Walnut Creek and Brentwood. By the estimates below, about 1,100,000 East Bay adults use AI chatbots.
Peninsula
The Peninsula is San Mateo County, from the coast at Pacifica to the downtowns along Caltrain. Bay Area AEO describes it as full of high-value customers who ask AI before they choose a restaurant, doctor or contractor. The city pages are San Mateo, Daly City, Redwood City, South San Francisco, San Bruno, Pacifica, Menlo Park, Burlingame, Foster City and San Carlos.
San Francisco
San Francisco has its own page with 18 named neighborhoods, covered in detail on the San Francisco answer page.
Reading the regional estimates
The table at the top applies the same three rates to each region's adult population. The East Bay is the largest market by far, with 2,240,000 adults and an estimated 1,350,000 who read Google's AI Overviews. The South Bay follows with 1,540,000 adults. The North Bay has 1,060,000, San Francisco 730,000 and the Peninsula 602,000. For a business, the useful figure is the number of nearby customers who now put their questions to AI, and in every region that number runs into the hundreds of thousands.
