For 2026 planning, gas engineering firms need benchmarks that help them diagnose performance rather than generic claims about what SEO should deliver. This page organizes the figures already recorded in the source into search-intent, local visibility, conversion, competitive, and trend categories.
The values are preserved as published, but the source does not include study URLs, sample definitions beyond the stated firm count in the summary, collection dates, query sets, attribution rules, or statistical methods. That means the ranges are most useful as directional comparison points for internal review, not as universal market standards or causal evidence.
Compare like with like: emergency repair demand behaves differently from planned installation research, domestic search differs from commercial procurement, and a genuine branch location should not be evaluated as though it were only a nominal service area. For the budget context that sits alongside these benchmarks, use the gas engineer SEO cost guide.
