Rule: For Ontario service-business clients in 2026, the Google Business Profile is still the primary local-lead surface — lock it down before anything else

Rule: For any Ontario service-business client, GBP optimisation precedes content, paid, and AI-surface work. Claim and fully optimise the profile — every field, accurate NAP, correct categories, services, weekly photos, active review generation — first.

Why: AI Overviews appear on only ~15% of simple local-intent queries (e.g., "electrician near me", "[city] roof repair") per Whitespark Q2 2025 local-search study — AI Overviews appeared on 15% of simple local-intent queries vs 92% informational vs 97% hybrid; local pack appeared on 93% of local-intent vs 6% of informational and ~17% of commercial queries per Local Falcon (2025) — AI Overviews on 17.2% of commercial queries vs 58.3% of informational; including a location name reduced AI Overview appearance (35% vs 46%). The local pack appears on ~93% of local-intent queries. With only 3 slots in the pack (since Pigeon update (July 24, 2014) — tied local algorithm to core web-ranking signals; credited with shrinking the local results from 7-pack to 3-pack), GBP is the single highest-leverage local-SMB asset and feeds AI local answers too.

How to apply: Stage 1 of any new client engagement. Before redesigning the site, before writing content, before turning on ads. Audit the existing profile, fill the gaps, set up the review-generation cadence. Re-evaluate this rule only if AI Overviews begin appearing at scale on the client's core "near me" / commercial queries.
