How long until I rank in the Antioch Map Pack?

60–120 days is typical for service businesses with a clean GBP and 8–12 fresh citations. Competitive verticals (auto repair, dental) take longer.

Should I publish my Antioch site in Spanish?

If 20%+ of your customers are Spanish-speaking, yes — bilingual landing pages and a bilingual GBP almost always lift Map Pack performance in Antioch.
