Before using any value in a proposal or forecast, identify what kind of evidence it represents. The benchmarks are compiled by AuthoritySpecialist from publicly available search industry research (BrightLocal, Moz, and Google Search Console aggregate studies), campaign observations from trade businesses, and widely reported industry benchmarks that have appeared consistently across credible SEO publications.
Read each figure by its evidence type. A figure from published research can be evaluated against its sample, publication period, and metric definition. A campaign observation is labeled as such where it appears, and an industry benchmark gives the range reported consistently across the sector, without attached client counts or false precision.
This distinction matters because contractor markets differ. A plumber in a smaller regional city, an HVAC company serving a dense metro, and a roofer working across several genuine operating areas can face very different search demand, competitive depth, customer urgency, and website maturity.
Do not use one benchmark as a substitute for your own baseline. A useful internal baseline includes qualified organic calls and forms, relevant landing-page traffic, local profile actions, booked work, and the cost of the marketing program that produced those outcomes.
Benchmark interpretation also requires consistent definitions. Decide whether a lead means any call, a qualified inquiry, an estimate request, or a booked job. Decide whether an attributed conversion belongs to the first recorded source, the final recorded source, or another documented model. Without those definitions, comparisons can look precise while measuring different things.
Use these benchmarks as a decision aid, not as a guarantee. The most defensible next step is to compare each cited range with your own service area, competitive set, tracking quality, and capacity to handle additional demand.
