Search engine marketing (SEM) is related to SEO in that they both deal with digital marketing outreach on search engines like Google and Bing. However, SEO typically refers to internal, organic website optimization while search engine marketing is commonly known as advertising through a paid media budget. While SEO will help your website traffic increase through natural algorithmic means, SEM earns traffic through the process of purchasing ads on search engines. In the image to the left, you will see a search engine results page that is the result of typing the keyword “digital marketing” into Google. The top four results have a small green box that says “ad” underneath the primary title link. This signifies paid advertising, or search engine marketing, where a brand or business has paid Google to display their ads at the top of the page for that specific keyword.
Consider the current status of your website. When you create a marketing strategy, look for the “low-hanging fruit”, or the opportunities that will make the biggest impact with the least amount of work Click & Tweet! . So before you launch a search marketing campaign, research your website to see where you may have the potential to grow an organic SEO strategy that is already working before putting money into an SEM campaign.
In 1998, two graduate students at Stanford University, Larry Page and Sergey Brin, developed "Backrub", a search engine that relied on a mathematical algorithm to rate the prominence of web pages. The number calculated by the algorithm, PageRank, is a function of the quantity and strength of inbound links.[22] PageRank estimates the likelihood that a given page will be reached by a web user who randomly surfs the web, and follows links from one page to another. In effect, this means that some links are stronger than others, as a higher PageRank page is more likely to be reached by the random web surfer.
Thanks for the helpful information discussing the differences and similarities between SEO and SEM. The information was enlightening because a search engine optimization company like the one that I own is relatively new at starting. We believe everyone should always check out their sources because every different perspective is very different so all approaches can be understood differently.
