Short answer: yes. Longer answer: it is no longer the only door into your business.
Google still handles the overwhelming majority of searches, and for most local and commercial queries it remains the first place people look. Nothing about AI search removes that.
What has changed
The way people research has widened. Someone might ask an AI assistant for three suggestions, then search each one on Google to check it is real. Being invisible in either place costs you.
The good news
The same work supports both. Clear structure, honest content, accurate business information and genuine expertise help a search engine rank you and help an AI tool understand you.
