For "near me" and "city + service" searches in Turkey, the Google map pack captures the majority of clicks and calls. If you operate physical locations, local SEO is not a subset of SEO — it is the main event.
The three levers
Relevance (correct categories and complete profile data), distance (which you cannot control), and prominence — reviews, photos, citations and the authority of your website. Reviews are the fastest lever: count, average, recency and owner responses all feed ranking.
NAP consistency
Your name, address and phone must match exactly across your site, Business Profile and Turkish directories. Inconsistencies — old addresses, format differences — quietly suppress rankings, especially after a move.
Multi-branch strategy
Each branch needs its own Business Profile and its own landing page with unique local content. Pooling branches into one profile is the most expensive local SEO mistake in Turkey, and undoing it later costs months.
