Hundreds of thousands of results will appear before the user on searching for a well known topic on any search engine. In this competitive scenario, Search Engine Optimization or SEO enables a firm to come within the top search results for a search relating to a specific word. Finding a place within the topmost results on common searches increases the number of people who are drawn to your website and therefore you do more business. That is the reason why SEO has become so important.

There are two types of SEO – white hat and black hat. The tools used in black hat SEO for ensuring a place for the website in the top results are not seen as fair practices. In contrast, white hat SEO follows all the principles laid down by the search engines and concentrates on the techniques which are commonly approved of.

The search engines previously matched a webpage with the search for a given word by making use of Meta data, which is generally embedded in the code of a webpage. However, these days most search engines use extremely sophisticated algorithms, involving the use of more than 200 different factors to come up with the results.

SEO experts have to be aware of all the new developments made by search engines and guess the relative weight of different factors in a search algorithm. This knowledge helps them fine-tune the SEO techniques for their clients so that they stay competitive for important keywords. Some time back, when the search engines relied upon Meta data and the text on the page, this process needed taking care of the Meta tags and ensuring a reasonable density with which a keyword existed on the page.

Although these factors are still quite significant, search engines now give much more weight to the popularity of a web page. The popularity of a web page is estimated based on the number of links to it from other web pages. Every single link is therefore taken as a vote for the page and the algorithm becomes democratic in nature. Because of this significant change, SEO now also involves many offsite strategies like distributing free content to get inbound links, and creating an extended presence through blogs and other forms of social media.

The important aspect of SEO to be always remembered is that it is not a one time task. The field is constantly changing and your techniques need to adapt to those changes. This is what makes utilizing the services of a professional SEO consultant so vital.
