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. Other forms of search engine marketing (SEM) target paid listings. In general, the earlier (or higher on the page), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine. SEO may target different kinds of search, including image search, local search, video search and industry-specific vertical search engines. This gives a website web presence.

As an Internet marketing strategy, Search Engine Optimization or SEO considers how search engines work and what people search for. 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.

The acronym “SEO” can refer to “search engine optimizers,” a term adopted by an industry of consultants who carry out optimization projects on behalf of clients, and by employees who perform SEO services in-house. Search engine optimizers may offer SEO as a stand-alone service or as a part of a broader marketing campaign. Because effective SEO may require changes to the HTML source code of a site and site content, SEO tactics may be incorporated into website development and design. The term “search engine friendly” may be used to describe website designs, menus, content management systems, images, videos, shopping carts, and other elements that have been optimized for the purpose of search engine exposure.

Another class of techniques, known as black hat SEO or spamdexing, uses methods such as link farms, keyword stuffing and article spinning that degrade both the relevance of search results and the user-experience of search engines. Search engines look for sites that employ these techniques in order to remove them from their indices.

Search engine marketing, or 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 search engine optimization, paid placement, contextual advertising, and paid inclusion.

Social media marketing is a recent addition to organizations’ integrated marketing communications plans.

Integrated marketing communications is a principle organizations follow to connect with their targeted markets. Integrated marketing communications coordinates the elements of the promotional mix; advertising, personal selling, public relations, publicity, direct marketing, and sales promotion.

In the traditional marketing communications model, the content, frequency, timing, and medium of communications by the organization is in collaboration with an external agent, i.e. advertising agencies, marketing research firms, and public relations firms. However, the growth of social media has impacted the way organizations communicate. With the emergence of Web 2.0, the internet provides a set of tools that allow people to build social and business connections, share information and collaborate on projects online.

Social media marketing programs usually center on efforts to create content that attracts attention and encourages readers to share it with their social networks. A corporate message spreads from user to user and presumably resonates because it is coming from a trusted source, as opposed to the brand or company itself.

Social media has become a platform that is easily accessible to anyone with internet access, opening doors for organizations to increase their brand awareness and facilitate conversations with the customer.

Additionally, social media serves as a relatively inexpensive platform for organizations to implement marketing campaigns. With emergence of services like Twitter, the barrier to entry in social media is greatly reduced.

Report from company Sysomos shows that half of the users using Twitter are located outside US demonstrating the global significance of social media marketing. Organizations can receive direct feedback from their customers and targeted markets.
