Definition of SEM

Search engine optimization (SEO) is the process of improving the volume and quality of traffic to a web site from search engines via "natural" ("organic" or "algorithmic") search results. Usually, the earlier a site is presented in the search results, or the higher it "ranks", the more searchers will visit that site. SEO can also target different kinds of search, including image search, local search, and industry-specific vertical search
engines.

SEO is not necessarily an appropriate strategy for every website, and other Internet marketing strategies can be much more effective, depending on the site operator's goals.[36]A successful Internet marketing campaign may drive organic search results to pages, but it also may involve the use of paid advertising on search engines and other pages, building high quality web pages to engage and persuade, addressing technical issues that may keep search engines from crawling and indexing those sites, setting up analytics programs to enable site owners to measure their successes, and improving a site's conversion rate.

SEO Vs SEM

Search engine marketing involves click costs. Search engine optimization works through free traffic. Those two facts are the basis of a popular myth: that it’s easier to get good ROI through SEO than it is to get the same ROI through SEM.

In SEM, you decide the landing page your visitors see. In SEO, a search engine spider decides on the landing page visitors see. That’s a difference in control, and that difference makes all the difference.
