what is the career scope in seo , internet marketing , social media ?

[Paula]

If you are just entering this field without some significant education and background you will be forced to charge almost nothing to get your portfolio built up. So, the answer is yes - you can create a career in these, but experience is winning today over price.

After the US economy took a dive and everyone who ever took a marketing calls "reinvented themselves" as marketers, messed up thousands of businesses with their lack of real knowledge, agencies like mine are cleaning up. The real businesses (the ones with budgets) are hesitant to work with freelancers. They are learning the importance of having strategy, tools, management, implementation and ROI in their marketing.

Go work for a big firm first so you can learn and understand the landscape. For every story like Facebook there are thousands of fizzled and under-funded startups that will not survive.

Good luck!
