Start with three things, in this order. First, claim your Google Business Profile and fill out every field: name, address, hours, services, categories. Google can't recommend what it can't verify. Second, pick your single most important service page and make sure the title, the main heading, and the first paragraph all clearly state what you do and where you do it. If someone lands on that page, they should know within five seconds whether you solve their problem. Third, install Google Search Console. It's free, and it shows you exactly which searches are bringing people to your site, and which ones almost are. That "almost" list is where your first content opportunities live. Don't try to learn everything at once. Fix one page, measure what happens, then move to the next. SEO is a sequence, not a checklist.
