The guide
Why it works.
Google ranks pages, not businesses. When someone searches "roof sealing," the results are pages about roof sealing. A homepage that lists ten services in passing competes against pages dedicated to the one thing the searcher wants, and it loses. The click test is simple: which result would you tap?
What a service page needs.
The service explained in plain words. What it costs, or how pricing works if it varies. Proof: photos of that specific work. The areas you serve, written out. And one obvious way to contact you. That's it; length matters less than relevance.
What to avoid.
Thin, duplicated pages where only the town name changes (search engines discount them). Keyword stuffing. A single "services" page that's just a list: a list can't rank for each item the way a page can.
How many pages?
One per service people actually search. If you do three things, that's three service pages plus your homepage and contact: five pages, which is not a coincidence in how we size plans.
