Two proposals can use the same label while funding very different work. A $1,500/month engagement and a $5,000/month engagement can both be sold as orthodontic SEO while covering very different scope, so compare the line items rather than the label.
Competition and search coverage
Evidence to request: the practice's priority treatment queries, genuine office locations, current search visibility, competing pages, and any backlink or citation gaps being used to justify work. A lower-competition market may require less remediation or publishing than a crowded metro, but competition should be demonstrated with search evidence rather than assumed from population size. Scope should specify which queries and locations are actually being addressed.
Included services
Ask whether the proposal includes technical diagnosis, implementation, Google Business Profile work, citation correction, treatment and educational content, internal linking, legitimate outreach, analytics, call or form attribution, and clinical review. The price should also state exclusions such as development hours, photography, paid media, software, legal review, redesign, migration, or practice-management integration. A low price is not itself a defect if the reduced scope is explicit.
Number of genuine locations
Each real office can add business-data review, profile management, citation correction, local measurement, and useful location-specific content. In some engagements, each additional location adds $500-$1,500/month, depending on how much profile, citation, and content work it needs; it is not a fixed surcharge. A nominal service area should not be turned into a location-page budget line unless there is a genuine location and useful location-specific information.
Starting technical condition
A site with crawl, rendering, mobile, migration, analytics, or content-architecture problems may need a concentrated remediation phase before recurring growth work can be evaluated. Require the proposal to identify the actual defect, the owner, the estimated effort, and the validation step rather than charging for generic technical optimization.
Use the orthodontist SEO audit guide to test whether the quoted work is tied to evidence. Where treatment claims, patient information, advertising, or other regulated content affects scope, budget time for review by the practice's legal, medical, or regulatory reviewers.
