I know what you are thinking – What a hassle, I do not have space, there is little profit.
But what if I told you that you could double your traffic to your website, bring new customers to your shop, bring old customers back to your shop more quickly to purchase new bikes, make a little extra cash, and is a free service that only takes about an hour a week, then would you be excited?
If you are having a promotion, add information (and a link) to your promotion at the bottom of each Craigslist ad and you see a substantial rise in interest for that promotion from people that would never have become aware of your shop or promotion.
There is a reason that newspapers are going out of business and it is Craigslist. You need to use it in your everyday promotion of your bike shop.
