SEO & SEM service
1. SEO
Search engine optimization (SEO) is the process of improving the volume or quality of traffic to a web site or a web page (such as a blog) from search engines via "natural" or un-paid ("organic" or "algorithmic") search results as opposed to search engine marketing (SEM) which deals with paid inclusion. The theory is that the earlier (or higher) 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 web site web presence.

2. SEM
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. Usage of the term "search engine marketing" has been inconsistent. The trade association Search Engine Marketing Professional Organization (SEMPO) includes search engine optimization (SEO), and SEO is also included in the industry definitions of SEM by Forrester Research, eMarketer, Search Engine Watch, and industry expert Danny Sullivan. However, the New York Times restricts the definition to 'the practice of buying paid search listings'.
