A lot of people now use Google Maps (GMaps) to search on their phones for a business - mainly so they then get directions immediately, rather than googling it, then switching to GMaps.
Recently, I was trying to find a Vietnamese restaurant that someone told me about. I did a search on Google Maps for Vietnamese
and couldn't find it. Thankfully, we had a rough idea where it was, so we drove to the car park nearest to where we thought it was and then walked around : it was in front of us! Actually, we'd actually driven past it hundreds of times as its only 50m back from a main road.
The food at the Vietnamese place was delicious - the Banh Mi was just like ones I've eaten in Hanoi, so I had a chat with the owners and they "claimed" the business and set their details.
Naturally, after a couple of days to ensure that the search engine, etc had been updated, I went on to GMaps and added a review and some photos.
I saw them again recently and the said that their sales have increased since they went onto GMaps.
