There are two main types of traffic available to the web surfers when using a Search Engine to locate information. There are Organic / Natural Listings and there are PPC (Pay Per Click) listings. Below you will learn the difference between the two and how to spot these different listings in the top 4 major Search Engines. DEFINITIONS Organic Placement - Organic Placement, also known as Natural and sometimes Free Placement, is the ability for the Search Engines to read your web site (also known as spidering, crawling or indexing) and based on your web site Metas, Content and Search Engine Popularity, place your listings in their displays at NO COST. This is not to be confused with PPC (Pay Per Click) placement where a vendor Pays Per Click to be seen. PPC doesn't care how well written the site is for indexing (IE: Is it Search Engine Friendly?); it only cares that the vendor is willing to pay to be seen. PPC (Pay Per Click) - Pay Per Click Programs are available through companies such as Google Adwords (this data is fed into the Google.com Search Engine), Overture.com (This data is fed into Yahoo and other Yahoo supported Search Engines) and smaller companies such as Find What and Look Smart. Pay Per Click Programs DO NOT CARE if your web site has been developed to be Search Engine Friendly. They simply want you to choose phrases that you want your site to appear on and they want you to pay every time someone clicks on that listing. You will know a PPC listing in any of the search engines because it will be denoted as a SPONSORED LINKS, RESULTS or SITES. So when you see the grouping heading SPONSORED LINKS, RESULTS or SITES, you know that if you click on a listing in that section, the Vendor will have their account charged at the point you click. Every system does their placement and cost structures a little differently, but what they all have is that when their AD gets clicked on, they pay - - - Every Time.

SITE SATURATION Finally, you will note that many of the Case Study examples have a web address and then a / with a file name, and possible sub-directory, appended on the end of the web address. This is because the various search engine(s) have indexed a sub page of the site - not just the home page. Large database sites have many, many sub pages of data that you absolutely want to be indexed. By indexing multiple sub pages, with different Meta Tags, the amount of traffic to those pages increases, thus increasing the overall visitors to the web site. Any web site with more than one page can do this to expand your visibility on the web. Database sites simply offer an abundance of sub pages to index.
