It does not matter if you’re purely an online operation!
Google research shows:
What is Local Search?
To be clear: Local search happens when users search for products & services using geographically constrained phrases. For example: ‘electronics Sydney’
Even a pure online operation can benefit from listing that is linked to the area where their offices are located. If you have multiple branches or offices in multiple cities, so much the better. These kinds of links will boost the authority of your domain and indirectly lead to higher rankings.
While it may seem paradoxical for an ecommerce store to be concerned about local search the Google My Business program can make a significant difference to ranking in search results.
Context Matters for Mobile
Context is especially important for mobile search. Because Google knows your location when you enter a search query from your mobile, it will try to understand your intention, so that it can deliver you a more useful search result.
