SEO benchmark pages often repeat precise-looking values without enough context to judge them. Claims such as 73% of contractors seeing results in 90 days or a 312% average traffic increase are rarely sourced and almost never reproducible, which is why this page uses ranges instead. A roofing contractor competing against 40 established local businesses faces a very different search environment from a specialty contractor with three direct competitors.
The benchmarks here were compiled by AuthoritySpecialist from three kinds of evidence: published search industry research from BrightLocal, Moz, and Google's own documentation; campaign experience from contractor engagements across residential and commercial trades; and market observation in competitive metro and smaller regional markets.
Ranges are intentional. Collapsing the variance between markets into a single number would mislead more than it informs, so each range shows the spread a contractor can plan around.
Market structure matters. A roofing contractor in a crowded metro, a specialty contractor in a smaller regional market, and a multi-location operation can face very different search conditions even when they target similar services. A single average can hide that variance.
Freshness matters too. Search systems, result layouts, and local-search behavior change. The structural patterns described here, such as local intent, authority compounding, and review signals, have held across multiple algorithm cycles, while individual ranking factor weights shift more often. For an operational check of the site's current condition, use the contractor SEO audit guide.
How to apply a benchmark: a benchmark is most useful when its metric definition, sample, period, and limitations are known; where some of those elements are missing, use the number as context rather than as a decision threshold.
