PPC ads are the largest and most popular form of internet advertising.
Pay Per Click Advertising (PPC) are ads you place for your website on a search engine. The ranking of your website will be determined by how much you are willing to pay per each click.
Pay for Inclusion (PFI) is a directory base web service such as DMOZ, Verizon's SuperPages or Yahoo directory. Why are both of these services important? You may decide to opt out of a website for search engine marketing, however nearly all businesses in this day and age are expected to operate an active website. The best ways to increase revenue for your business is to expand and implement cost-effective marketing strategies. Search engine marketing is a great way to increase traffic flow to your website, leading to new customers as simple as a click away. Free listings such as DMOZ can cost as little as $30 per year. Similarly, pay per click can be inexpensive as you will be able to set limits on how much you are willing to pay per click per day.
You can simply compare your web traffic statistics before and after you have implemented search engine marketing to measure the effectiveness of SEM for your site. In addition, you will need to track your conversion rates. For instance, if your traffic doubled after your search engine marketing efforts, how many new customers have you acquired from the new visitors. Twice as many as before? If just 10 new customers out of 500 new visitors, than you've attained a conversion rate of 2 percent (10 divided by 500).
Pay per click is just one of the many search engine marketing tools available to businesses when it comes to online marketing.
