SEO stands for Search Engine Optimization. This is a strategic procedure which helps a website to be recognized by search engines. Literally, SEO improves a website’s digital footprint, global visibility on World Wide Web.

Every search engine works upon a basic set of algorithms. These algorithms identify the websites and short list them according to priority and popularity when a related thing is being searched. The term popularity means traffic. A simple logic works over here, “if a internet user gets some useful information in a domain, then he or she will return to the same domain next time he or she needs something relevant.” Here comes the concept of quality. People would visit a second page on that domain if the landing page is informative and useful, easy to use and not complex in looks. Every online business sites can have these features. Still, to be at the top of the list enlisted by the search engines or to appear in the front page, the web contents are optimized.
There are numerous ways to optimize a website for the search engines. Few of them are:
-On-page optimization (Meta-tags)
-Off-page optimization (Link Building)
-Keyword Research
-Article submission (Directories)
Out of these four methods, the on-page optimization is the most genuine and permanent one. It includes adding of landing pages to a certain domain, where articles or texts (written as per the search engine optimized keywords) are displayed with a call to action to site’s services.
Link building is like dragging traffic to a website by diverting them. The website’s link is given on other website’s landing pages and customers are redirected accordingly. In case of directory submissions, if a certain directory gets enough traffic, it gets republished. The parent domain gets benefited with traffic with no extra efforts.
Still algorithms like Google Panda and Penguin are capable of identifying genuine information and sites, SEO isn’t necessary at all, but competition brings it into existence.
