Short answer: local SEO starts with a coherent Google Business Profile, clear service pages, visible proof, reviews, a realistic area and a website that makes contact easy.
Start with the Google profile
The profile should show the right name, activity, phone, hours, address or served area, photos and a useful website link.
Create pages that really answer
A local or service page should explain the need, work, limits, proof, lead times, area, frequent questions and the way to request a quote.
SEO, AEO and GEO
Search engines need structure, visitors need direct answers, and AI engines need clear facts they can understand and cite.
