Search engine optimization (SEO) is the process of improving the visibility of a website or a web page in search engines via the "natural" or un-paid ("organic" or "algorithmic") search results. In general, the earlier (or higher ranked on the search results page), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine's users. SEO may target different kinds of search, including image search, local search, video search, academic search, news search and industry-specific vertical search engines.
As an Internet marketing strategy, SEO considers how search engines work, what people search for, the actual search terms typed into search engines and which search engines are preferred by their targeted audience. Optimizing a website may involve editing its content and HTML and associated coding to both increase its relevance to specific keywords and to remove barriers to the indexing activities of search engines. Promoting a site to increase the number of backlinks, or inbound links, is another SEO tactic.

Search engine marketing, (SEM), is a form of Internet marketing that seeks to promote websites by increasing their visibility in search engine result pages (SERPs) through the use of paid placement, contextual advertising, and paid inclusion. Search engine optimization (SEO) "optimizes" website content to achieve a higher ranking in search results, for example, by incorporating specific keywords or links associated with the website. Depending on the context, SEM can be an umbrella term for various means of marketing a website including SEO, or it may contrast with SEO, focusing on just paid components.

Hi..flocks..

According to SEO point of view,  SEM is the all encompassing broad phrase that includes SEO as well as paid search activities such as Google AdWords purchases.  SEO, on the other hand, is simply a subset of SEM. Some people mistakenly think that SEM means PPC and SEO means organic SEO but it is not true.

Thanks
