Search Engine Optimization can yield powerful results. However, how do you measure the extent of the success SEO can bring? Interfaces such as Google AdWords or Bing Adcenter can provide much needed insight. With one of these tools you can measure the rate at which your site gathers impressions and which of those impressions convert to clicks. Purchasing a sample campaign for a certain “keyword” can bring forth a great benefit. A keyword is a search term or phrase that is typically typed in to search engine inputs prior to commencing a search. For example, if you were hoping to find information about Peyton Manning, typing “Peyton Manning Denver Broncos” into the search bar uncovers the most relevant results. The keyword in the query is Denver Broncos. From this, the most pertinent and relevant data is often discovered based on links and the amount of “hits” or visits each site gets. This leads into the development of the strategy known as SEO or Search Engine Optimization. Search Engine Optimization stresses importance on the placement of keywords that allow your site to gain more “organic” visibility. Traffic to any web site can sometimes be rewarded with financial incentives. The two most common packages are “CPM” cost per mil, implying how much a site gets paid for 1,000 impressions, or pay-per-click which assigns a fixed value every time a site is accessed by clicking on the ad. Both Google Adwords and Bing Adcenter specialize in PPC. Therefore, the value of the sample campaign can be limitless. Impressions as mentioned, are converted to visits in what is called a click-through-rate. Adwords campaigns can give your site more visibility and can accumulate countless impressions in a twenty-four hour period. An excellent click-through-rate is about 30 to 40%. If any site reaches this mark with the given impressions, they will total 1,500 to 2,000 visits per day. At a rate of $3 per visit, the return is astronomical. This concept is a favorite of guerrilla marketing, an innovative approach involving low-cost techniques for maximum gains . However, SEO is the new innovation. The best way to explore SEO is search marketing.
