Hello everyone, i feel interest on freelancing. For that i want to be an expert on SEO. How can i preparate myself as a SEO expert?
Hi Kibria2841 and welcome to the forums. 
Are you familiar with SEO techniques and wanting to know how to get into the business as a freelancer, or are you a beginner wanting to learn about SEO?
Thanks. Hmm i am a beginner. Really i want to build up my carrier as a freelancer and want to start with SEO.
OK, then I suggest you download Google’s Search Engine Optimization Starter Guide to begin with, and also have a look at some of the sticky threads and other threads in this forum, which contain a wealth of information.
If, after that, you have a specific question which has not been answered, please feel free to start a new thread. Meanwhile, I’m closing this one, as the topic is much too broad to attract meaningful replies.
I should also warn you that you may find it difficult to get work in the SEO field. There seem to be an awful lot of people offering SEO services, and unfortunately the unscrupulous ones have given the sector as a whole a pretty bad name. However, if that’s what you want to do, by all means persevere. Good luck.
