Search engine optimization (SEO) is a set of activities aiming to improve the visibility of a website in organic search results (also referred to as non-paid or natural search results) for a specified set of keyphrases (search queries selected for promotion).SEO is one of the most efficient strategies for getting maximum benefit from your online presence. A company that offers such services is called an SEO company.
Search engines use specific algorithms to determine what website will be ranked higher for some particular query in search results. These algorithms are kept strictly confidential, but their general concepts and principles can be found if you spend some time and analyze search engine behavior.
These algorithms are constantly changing, so you will have to constantly track these changes. Besides there are some prohibited SEO techniques that you should know if you do not want to be penalized by search engines. That is why it is still better to order SEO services from some SEO experts, if possible.
