The Fundamental Difference Between SEO and SEM

By Michael Fleischner

Many individuals new to web marketing have some questions about search engine optimization and search engine marketing. Are they one in the same? How are they different? SEO and SEM have many similarities but are not the same.

First, lets focus on how search engine optimization (SEO) and search marketing (SEM) are similar. Each of these online marketing techniques requires a basic and advanced understanding. SEO requires knowledge of search engine and how to effectively optimize a website or web page. SEM requires knowledge and understanding about online marketing, online advertising, and keyword marketing.

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.

SEM success is based on an understanding of running online marketing campaigns across various advertising networks. The largest networks are Google, Yahoo! and MSN. Each works differently but at the same time, the general premise is the same. You place an online ad that displays when users type in specific keywords that you identify. If a browser clicks on your display ad, you pay a fee regardless of whether or not they convert into a customer.

Search engine optimization is unique and different from search engine marketing because the organic result which appears in search engines is driven from your optimization techniques. These techniques are broken down into on page optimization and off page optimization. On page optimization is closely tied to web site design and off page is more associated with in bound links to your website.

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.

Search engine marketing is different than SEO because with SEM you pay only when users take a specific action. Unlike traditional advertising you do not pay for an ad to simply appear. Rather, you pay when a browser clicks on your ad. Your advertising costs are related to a number of factors including keyword competitiveness and ad placement.

Doing business online requires a firm knowledge of both search engine optimization as well as search engine marketing Both internet marketing disciplines can support your online success. If you are not currently comfortable with SEO or SEM, begin with some simple research, explore SEO and SEM products, or subscribe to an RSS feed. Doing so can improve your knowledge and expertise in both of these areas.
