Shared City Names Give Unrelated Local Businesses 50% Keyword Relevance for Links
Cross-niche local link building connects unrelated industries whenever their target keywords share a location.
David Quaid explains that a shared town name makes search terms across separate business verticals 50% relevant to each other.
Even though the businesses operate in different industries, "painting in Slough" and "commercial painting in Slough" map onto "moving services" or "delivery services in Slough" through the shared location term.
Pages that cover other local businesses and can receive links from them help Google understand the relationship between the two domains as long as they help both sites rank.
