There's no universal certification for dental SEO expertise, so you're evaluating evidence, not credentials. Here's what that evidence should include:
Dental-Specific Local SEO Experience
Dental SEO is local SEO. Most of your new patients come from within a defined geographic radius. An agency that primarily handles national e-commerce SEO or B2B SaaS companies has a different skill set than what you need. Ask specifically: Have they moved dental practices into the Google Maps Pack? Do they understand NAP consistency, GBP category selection for dental practices, and review acquisition strategies that comply with platform terms of service?
Clear Deliverables, Not Just 'Monthly SEO'
A vague scope of work is one of the most common sources of conflict between dental practices and agencies. Good agencies will specify: how many pages of content per month, what technical audit work is included, what link-building activities they'll execute, and what reporting cadence you'll receive. If the proposal says 'full SEO services' without itemizing those activities, push for specificity before signing.
Realistic Timeline Communication
In our experience working with healthcare practices, meaningful organic traffic growth typically begins to appear between four and six months after engagement begins — and that assumes a clean technical foundation, consistent content production, and an active link-building effort. Any agency that suggests significant results in thirty or sixty days should be asked to explain the mechanism behind that claim.
Asset Ownership Is Non-Negotiable
You should own your website, your Google Business Profile, your Google Analytics property, your Search Console account, and any content produced under the engagement. Some agencies set up accounts in their own name and use that as use to retain clients. Get explicit language in the contract confirming ownership and access transfer upon cancellation.
