People searching for a lot to build a home are often concerned with avoiding roads with a lot of traffic, but the opposite is true for a retail business. They want plenty of potential customers driving by every day, and it is often one of the reasons they find a particular location suits them. Their business sign is an invitation to come and look at their wares, and their visibility to commuters will help get their name out into the local community.
A busy street has other advantages for a business, but it may depend upon how much room they can devote to parking. A small lot will only offer space for a limited number of customers, but the business may have more parking in back. Those that do often find the convenience of being able to park near a door is what will drive customers in to make purchases, so they do their best to find a location where they can provide for that necessity.
Deliveries can be an issue for businesses that require large trucks to deliver a great many goods at one time, so being able to handle that type of traffic is important. Smaller roads are often weight restricted, so avoiding them can be a good idea when a company is expanding. Rather than being in a quiet neighbourhood with only local traffic, the idea of commuters and large trucks passing them on a regular basis could be the ultimate draw.
Businesses and homes are two very different worlds, and the needs of a growing company are many. Finding just the right location depends upon the individual business needs, but traffic is a major plus for most retail outlets. The location alone can be part of their advertising budget, and it can make them easy to find and use when potential customers are ready to buy.
