It’s often said that it’s easier for a business to keep existing customers than to gain new ones. But it also works the other way around. It’s often easier for customers to buy from the same business than to look for a new supplier.
A photography customer that already has a go-to photographer will continue to use that photographer, (unless the photographer really messes up), because it’s easier than trying find a new photographer. A search for the phrase “toronto photographer” can result in 50 pages of search results. No one has time for that.
It’s always easier to continue doing things the usual way because there’s little or no risk. The usual way produces the usual results.
