Google needs to know what you do and where
Every important service deserves its own page with a clear title. List the areas you serve in real text, not only inside an image.
Identical name, address and phone
Use exactly the same contact details on your site and every listing. Small differences confuse search engines.
Real reviews
Ask happy customers for a review right after the job. Replying to all of them, good or bad, shows the business is active.
Speed on the phone
Most local searches happen on mobile. A slow site loses the call before the customer reads your name.
