HVAC service contractors

A summary of what distinguishes high-visibility domains in this industry, based on signal correlation patterns and LLM recommendation data.

Focus on signals with the strongest Rank Influence — these have the most reliable relationship with AI recommendations for this industry.

This industry has 11 identified audience personas derived from LLM query patterns. Each represents a distinct user intent with its own signal correlations and top domains.

Signals and top-ranked domains can differ significantly between personas — use the links below to jump directly to a persona's analysis.

Spearman rank correlations (ρ) between each measurable signal and the LLM recommendation score across all 454 domains in this industry.

Higher absolute ρ values (closer to ±1.0) indicate stronger relationships. Positive ρ means more of this signal correlates with better AI visibility. Rank Influence summarizes the practical strength — prioritize Dominant and Strong signals when optimizing.

How often AI models recommended each domain when answering HVAC service contractors queries across all personas. Each LLM run represents one query — the left chart shows raw recommendation counts, the right shows what percentage of queries included that domain.

275 total LLM query runs across all personas for this industry. A domain appearing in 50% of queries means AI models recommended it in half of all runs — regardless of list position.

A cross-signal snapshot for the 25 most LLM-recommended domains, showing values across all tracked signal categories — from backlinks and crawl data to Reddit, Wikipedia, and search engine visibility.

Domains appearing most frequently in Google search results for HVAC service contractors queries — counts are filtered to only the search queries associated with this industry.

Compare with the LLM recommendations chart above. Gaps between the two — domains that rank high in search but low in AI, or vice versa — reveal strategic opportunities or risks depending on your channel focus.

Domains ranked by backlink authority signals derived from the Common Crawl web graph: PageRank, total backlinks, link authority (AUC), and harmonic centrality.

Backlink authority is one of the strongest predictors of LLM visibility in most industries. Domains with high PageRank but a low LLM score may be underrepresented in AI recommendations despite their web authority — a potential gap worth investigating.
