PPC is still working pretty well, and even some very large firms whose hosting portals are already on front page of Google for their targeted keyterms are still heavily investing in PPC campaigns, why? Because end users would see relevant ads on blogs, forums, directories and other sources of information as they surf and the net and then click on them and study the packages and may even place orders.
Having said that, you can also spend thousands of dollars on PPC and still do not feel very satisfied, again why? Because issues like targeting the right audiences, putting great ads and links in front of potential customers and even selection of the wordings of the commercial can greatly affect the outcomes. You can also consider renting a monthly ad position on a few directories for the start.
