There are many net classified sites where you can place your free classifieds. Some of the best ones are Craigslist, Kijiji (owned by eBay), BackPage, and Hoobly but you can see plenty more if you try a search on any search engine. Sites vary in what the free membership includes and you can always upgrade to a nominal monthly charge if you’re feeling that it is necessary to get the features you need.
In any case, post as many classified advertisements as the site allows. You can likely have to go through a little bit of trial – error with many different advertisements before you start to see what it really working and what isn’t. Another reason that the Internet and advertising are so compatible is actually because your ad will feature a hyperlink to your internet site. So your audience just clicks on the link and they’re immediately at whatever it is that you need to offer. Even if you capture your audience’s interest, they may easily forget your website when it comes time for them to log on.
