Local SEO sounds technical, but most of it is making sure the same accurate information about your business appears everywhere, and that your site says clearly what you do and where.
Work through the list
Each item takes minutes. Tick it off when it is done; your progress is shown as you go.
Keep your details identical
Your business name, address and phone number should read the same on your website, Google, Apple Maps, Yelp, Facebook and any directories. Small differences, like "St." on one and "Street" on another, are fine; old phone numbers and old addresses are not.
Give each service and area a page
One page per main service, with the towns or neighborhoods you cover mentioned naturally, gives search engines and customers something specific to land on. Avoid near-copies of the same page with only the town name changed.
Come back to the list every few months. Most problems creep in when details change and one listing gets missed.
