yeah i am having 7years experience with this field .i have handled several projects like forum posting, guest blog post, write article content , building link , and also achieved some page ranking projects.now i develop my carrer using this way .............
experience SEO is as important as SEM
For example I work for a network that generates half billon page views and when we start up a new service we worked hard on SEO.
After one year 60% of the traffic comes from natural searches although the service is linked from every page of the network almost.
Itâ€™s a very good investment, the only issue is you dont have immediate return in the same way you have it in SEM, but when you reach a good rank, the traffic doesnt vanish if you stop spending money for a couple of months
I have worked on three to four different projects one wast related to videos, other two was manual and one was automated. Automated was also good but clients were getting notice from google on the frequent basis while manual was a bit costly but really great and with diversity in links have approached to PR4 from 2 but alexa it came down from 2100000 to 1900000 in a week and became steady at 1900000 till now.
I am newbie in SEO industry but worked on one project i.e., I did social profiling for the period of 3 months and I got to know that to get good rank for the site proper understanding of technique is very essential to succeed in SEO.
