Search Engine Optimization, popularly known as SEO is the practice of enhancing the quantity and quality of traffic to a website and affecting the visibility of a website or a web page through organic search results. In simple words, the website that occurs more frequently in the search results list receives a number of visitors and these visitors can be converted into customers.
How does it work?
Many of us see the search engine as a website where we type our queries or speak to when in doubt. Whether it is Google, Bing, Yahoo or any other search engine as soon as you ask the question it displays innumerous links in front of you that might possibly have the answer to your question. Well, that's true! But, have any of you wondered how this magic takes place? No? Here's the secret to links: The search engine has a crawler, as soon as you type your query this crawler goes and gathers all information regarding the same. This information is brought back to the search engine in order to build an index. That index is then fed through an algorithm that tries to match all the gathered information with your query. In this manner, related information to your query is delivered to you by the search engine.
Types of SEO:
There are two different types of SEO viz., White Hat SEO and Black Hat SEO. In the white hat SEO, methods and techniques are used in such a manner that it improves search engine ranking of a website which doesn't run into conflict with search engine guidelines. Whereas, the black hat SEO exploits the weakness of the search engine algorithm so that a website can rank high in the search engine. These techniques are a direct conflict with the search engine guidelines.
The algorithms of SEO keep changing on a frequent basis and the techniques and tactics of SEO change accordingly along with the algorithms. So, if anyone is giving you SEO advice don't trust them blindly instead research yourself first and then implement. With SEO you can make your page as most top rated and renowned one, learn SEO and incorporate it in a right manner for amazing results.
