If you are new to Internet marketing, you may have some questions about the difference among search engine optimization and search engine marketing. These core marketing subjects are very different but share a number of similarities as well.

Search engine optimization (SEO) and search engine marketing are similar in many ways. Each online marketing discipline requires a strong understanding of purpose and functionality. The practice of SEO requires a basic knowledge of search engines and how they work at their core. Search engine marketing requires an understanding of online marketing and advertising.

Both internet marketing methods may appear as difficult subject matter but they are relatively easy to understand. The complexity comes in the actual implementation of SEO and SEM programs. SEO can be explained as techniques that used to drive your search engine ranking. Simply state, where your site is ranked on major search engines is based on your understanding and implementation of SEO best practices.

Search engine marketing is the practice of online advertising via major search engines. Even though Google is the largest and most well know, there are literally hundreds of smaller ad networks. Each network functions in much the same way. Advertisers place online ads throughout the network and when a browser clicks, you pay a fee. This is true regardless of conversion.

SEO is different than SEM because it is based on natural or organic search results versus paid results. Search engine optimization techniques can be better defined as on page optimization and off page optimization. On page optimization directs you on how to design your web page in an effort to improve ranking and search ability. Said another way, on page optimization is closely tied to web site design and off page is more associated with factors outside your website itself.

The result is that SEO drives organic traffic. That is to say that after users complete searches on major search engines like Google, the resulting list is based on search engines returning the best result determined by their unique algorithm. When users click on these results you do not pay. Organic search is usually referred to as free traffic.

SEM is different than search engine optimization for one fundamental reason. With SEM, you pay when someone takes an action. Unlike traditional advertising you do not pay for your advertisement to appear, only when someone clicks on your ad. Your cost varies based on how competitive your keywords are and where you want your ad to display.

Online marketing is based on a good understanding of SEO and SEM best practices. These internet marketing subject areas are common among today’s marketing professionals but rarely do you find the level of expertise needed for success.
