This checklist is built for oil change shop owners, managers, and staff who want to improve local search visibility without hiring a full agency. You have a website, maybe it ranks on page 2 or 3 in your local area, and you're losing customers to competitors who appear at the top of Google.
The 27 steps assume you have basic access to your website (or can ask your current web host), a Google Business Profile, and 4 – 6 hours to work through the quick wins. Some steps require paid tools (under $20/month); most are free.
This is not a replacement for ongoing SEO management if your market is highly competitive or if you want to scale beyond one location. But it shows you exactly what the work entails — and you'll notice what's feasible in-house versus what benefits from expert help.
