1. List on Google My Business (formerly Google Places), Bing Places and Yahoo Local
Listing on these directory sites can improve your website search ranking and the good news is, visitors looking for music equipment on local listings are more likely ready to purchase. Overall, listing your business online increases visibility which in turn increases website traffic and awareness which increases sales. Cha-ching!
2. If you don't have a blog you should start one right away.
Blogs are a great, free way to demonstrate your expertise and build relationships with your existing and future visitors to your music store. Share your informative blog posts with potential customers as a way to introduce yourself and your business. Write about things that your core customers are interested in and based on questions that they frequently ask. This way your content will attract people who are just like them and who will be more willing to do business with you.
