Cost Per Click: It is the amount an advertiser pays each time someone clicks on their ad. CPC programs (CPC affiliate programs or PPC pay-per-click programs) pay the website affiliate or owner a certain amount a click for displaying ads.
PPC Advertising: Experienced affiliates use pay per click (PPC) advertising on Google's AdWords, Yahoo and MSN to promote mini-sites or specially designed landing pages. This is highly effective and an easy way for a beginner to spend more than any commissions earned. While trying this technique, go slow and be ready to do a lot of learning.
Wordpress: WordPress is a blog publishing system written in PHP, backed by a MySQL database. Developed by Michel Valdrighi, it is the official successor of b2\cafelog. On this site you can download or install a software script called WordPress. For this, you need a web host to meet the minimum requirements and time. Completely customizable, WordPress can be used for almost anything. WordPress.com lets you start with a new and free WordPress-based blog in a matter of seconds. However, it is different in several ways and less flexible than the WordPress you download or install yourself.
Backlink: Also called "back links", these are links from other websites to your site. They're also known as inbound links, incoming links or IBLs. As links from your site to others are forward links or hyperlinks, those going the reverse direction are backward links or backlinks.
CPA: Also called cost per action, this is a commission paid by an affiliate merchant or advertiser each time someone clicks a link on the affiliate's website, goes to the merchant site and takes an action like signing up for a newsletter, buying a product or requesting information through a form. "Cost per action" describes action from the merchant's view.
Lead: This, in marketing, refers to information that may eventually help make a sale. If someone enters their name and email id in a form on a website for receiving information on a vacation in Greece, the data entered in the form is a "lead". Advertisers pay for leads, for which there are pay-per-lead (PPL) affiliate programs. PPLs help affiliates earn commission even when no product is purchased.
