Earn A Good Site Rank

Earn A Good Site Rank Even With A Single Post


Can we earn a good site rank and be at the top 10 of a search ranks easily? Are there any easy ways to earn a top rank at the early stage of a web site or a blog? Do we have to learn a lot about search engine optimization using expensive methods? This is questions that bother lots of young bloggers and web designers.

The answers to all these mind bobbling questions are “yes it can be achieved”. But how? Well.. This is one simple way to do it.

· First think of a topic that you have some knowledge about and a one that you think which is very uncommon.

· Then type that topic on a search engine and see how many search results will appear for that topic. (If the numbers of results are less then you have a better chance of getting a top rank.)

· Design the web site or the blog. Try to make it more interesting for the visitors. Use small pictures and small animations to make things that you are presenting more attractive.

· Don’t forget to put your topic (which is the keyword) as many times as you can inside the content of the web site or the blog.

· Then submit the one that you have created to popular search engines.

Then its done!... Now you will achieve a top rank in search engines.

This is one example of a success story. This “post” is written about the “isass virus”. See the results for yourself.
