Definition:
SEM or search engine marketing is the process of building and marketing a site with the aim of improving its position in search engines. SEM includes both search engine optimization (SEO) and pay-per-click (PPC) or Search Advertising (SEA), as well as the use of all other areas and services offered by search engines.
Difference between SEO and SEM
SEM is the broadest discipline you incorporate into SEO. SEM includes both paid search results (using tools like Google Adwords or Bing Ads, formerly known as Microsoft adCenter) and organic search results (SEO). SEM uses paid advertising with AdWords or Bing Ads, pay per click (particularly beneficial for local providers, as it allows potential consumers to contact a business directly with a single click), advertising and also make sure that seo has been done. A keyword analysis is done for both SEO and SEM, but not necessarily at the same time. SEM and SEO need to be monitored and updated frequently to reflect the evolution of best practices.
The SEM and the PPC
In some contexts, the term SEM is used exclusively in the sense of pay-per-click, in particular in the advertising and commercial marketing communities, which have a personal interest in this definition. Such use excludes the broader search marketing community that is engaged in other forms of SEM, such as search engine optimization and search retargeting.
SEM in Social Networks
Another part of SEM is social media marketing (SMM). SMM is a type of marketing that involves exploiting social media to influence consumers, to convince them that a company’s products and/or services are valuable. Some of the latest theoretical advances include search engine marketing management (SEMM). SEMM refers to activities that include SEO, but focuses on investment management performance (ROI) rather than creating relevant traffic (as is the case with mainstream SEO). SEMM also integrates organic SEO, trying to reach the top search position without using paid means to achieve it, as well as pay per click. For example, some of the attention is placed on the design of a web page and how the content and information are displayed to the website visitor. SEO and SEM are two pillars of online marketing and both run side by side to produce better results by uniting them in turn into a single pillar.
