Selling something intangible.
THE CORE PAGES
One page per service, in detail, rather than one page listing everything.
A page about a specific service can rank for that service. A page listing eight services ranks for none of them well.
WHAT EACH SERVICE PAGE NEEDS
What the service is, plainly Who it is for What it involves What it costs, or how pricing works What happens next
Evidence: examples, testimonials, credentials
PRICING
Publishing prices, or at least ranges, is uncomfortable and effective. Visitors who cannot find pricing frequently leave rather than asking.
LOCAL RELEVANCE
Service plus location queries are where most service businesses realistically compete. Make the areas you serve explicit.
TRUST SIGNALS
For services, the decision is largely about trust: credentials, testimonials, photographs of real people, a physical address and a phone number.
CONTENT
Answer the questions customers ask before hiring. Those articles bring people who are close to a decision.
