How to choose a marketing agency in San Jose

  • Ask who will actually do the work and how you'll see results each month.
  • Be wary of anyone who guarantees rankings. No one can promise a spot in Google.
  • Make sure you own your website, ad accounts and Google Business Profile, not the agency.

How San Jose businesses get found in Google and AI answers

  • Claim and complete your Google Business Profile, then keep hours, photos and services current.
  • Use the same business name, address and phone everywhere you are listed, including directories like this one.
  • Publish pages that answer the questions customers actually ask, so ChatGPT, Gemini, Perplexity and Google AI Overviews can cite you.
  • Add LocalBusiness schema, clear pricing and service pages so AI assistants and booking agents can read your details.
