I want to advertise my business on the web.
There are lots of places to advertise on the web. The question is, where are your potential clients looking? What problem do you solve for them? How do you solve their problem? Why should they trust you?
Before wasting your time posting, figure out your strategic marketing plan. Then, you can advertise for the right customer at the right place at the right time (and stand out from all the other free advertisements).
