SEO or search engine optimisation is a process of enhancing the quantity and quality of site traffic to either a site or a particular web page by search engines like Google, MSN etc. SEO targets mainly unpaid traffic and not direct traffic from advertisers. This sort of traffic is called organic traffic as the search engine algorithms for this sort of traffic are such that the user does not have any specific incentive to visit a site and hence the site gets more hits on a regular basis, which eventually results in higher search engine rankings for the site. Organic traffic is also more targeted than paying traffic as the user has no definite motive to visit the site and hence the search engines normally give more weight to such sites.
The first thing to do in SEO is to select a keyword or keywords to promote your website or web page. Many people make the mistake of picking irrelevant keywords. Make sure you select relevant keywords that have enough competition in the market. You can also use tags and meta tags to improve the ranking of your site. Meta tags allow you to specify rules for the website page that can be used for generating further information about the keyword.
Keyword research is an important part of SEO and content writing. One should check if the keywords you have chosen are very competitive. A keyword is said to be competitive if it has less searches but still receives enough traffic. Also make sure that you have the correct content on your site. Content writing refers to the creation of content for a web page. It includes text, images, video, and other related material.
