Irving Oil's nearest audiences are shaped by regional everyday retail and services — hardware stores, pharmacies, grocery chains, community banks — not other fuel brands. Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 1.0 indicates near-identical audience shape.
Aubuchon Hardware leads the top 10 at 0.95, followed by Hannaford Pharmacy (0.92) and Hannaford Supermarkets (0.92) — three distinctly different retail subcategories, all clustered tightly at the top. Community Bank (0.90) and NBT Bank (0.88) add a second thread: community banking, the kind of institution anchored to the same regional footprint as a local fuel and convenience network. Bob's Big Boy (0.86) and Fox's Pizza Den (0.82) represent casual dining; Label Shopper (0.85) brings value apparel; LBM Advantage (0.83) adds a commercial building-materials thread. Rounding out the ten, Stewart's Shops (0.81) is the only neighbor in the Convenience & Fuel category — and it is a convenience store, not a gas station. No other Gas Stations subcategory entity appears in the top 10.
The scores are spread across a wide range of subcategories with no single cluster dominating, which is consistent with the broad shape: Irving Oil's audience overlaps with the full ecosystem of regional, community-scale commerce rather than concentrating around any one kind of entity.
