Score each candidate from 1-3 in every area, then keep notes beside the score. The number is useful only when the evidence behind it is written down.
1. Relevant Local-Search Experience
Ask for work that is comparable to your situation: HVAC or another service-area business, a similar level of local competition, and a business model where calls or booked jobs matter more than national traffic. Do not accept a logo wall as proof. Ask what the starting problem was, what the provider changed, which assets it controlled, and what evidence is available to support the result. Experience with Google Business Profile should include access management, category and business-information hygiene, landing-page alignment, and a process for resolving profile issues without inventing locations or violating platform rules. If the closest example is a B2B company, ask the provider to explain which lessons actually transfer to a local service-area business and which do not.
2. Reporting You Can Reconcile
Request a sample report before you sign. It should make it possible to trace completed work to observable search data and, where your tracking setup supports it, to calls, forms, booked work, or other business outcomes. Rankings can be useful diagnostic data, but they should not be the entire report. Ask whether you retain direct access to Google Search Console, analytics, call-tracking data, and relevant Google Business Profile performance data rather than receiving screenshots only. The HVAC SEO statistics resource can help you separate a real measurement discussion from unsupported industry talking points.
3. Explainable Link and Citation Work
Ask the provider to describe where links and citations come from, why those sources are relevant, how placements are reviewed, and what happens if a third party removes a link later. A useful answer distinguishes directory or citation cleanup, legitimate outreach, digital PR, supplier or association opportunities, and content-led earning from schemes designed mainly to manipulate rankings. Avoid any proposal that depends on secrecy, rented networks, mass placements, or a promise that authority can be manufactured on demand.
4. Timeline Claims That Match the Work
A credible provider should describe a sequence of diagnosis, implementation, validation, and iteration rather than promise a ranking date. A 4-6 month planning horizon can be reasonable for evaluating whether implementation is producing directional evidence, but it is not a guarantee that a particular query will reach a particular position. A promise of page-one rankings in 30-60 days should lead to specific follow-up questions about the targeted queries, starting position, competitive context, and tactics. If the explanation depends on a mechanism the provider cannot document or demonstrate, lower the score.
5. Ownership, Access, and Exit Readiness
Confirm that the business controls its domain, website, hosting, Google Business Profile, analytics, Search Console, content, and any new accounts created for the engagement. Ask how credentials are stored, how access is granted, and what the handoff looks like if you leave. External publishers control their own sites, so no agency can literally transfer ownership of a backlink; what you can require is a clear record of placements, outreach, invoices where applicable, and any dependencies that could disappear after termination.
