If you use blogging, you need to also promote your blogs..You can not just blog and let it sit there then expect it to help your SEO work

We utilize all of them...

I would use everything, in effective manner for marketing either products or websites. Digg, stumbleupon, and delicious are the best options out there. It works, really works. I just have to maintain the level.

I know how frustrating it is to find a
clear answer to social marketing.
Been there done that.

Have you considered this?

Each of the social marketing methods have
strong supporters because each are effective
to varying degrees; however, I don't read much
on people taking advantage of the vast pool of
highly targetted traffic Facebook offers.
Consider each person is identified by age,
interest, grouping,etc. You can reach huge
numbers with a carefully thought out presentation targetted to your specific interest.



If you need further help, contact me, or
post your questions here on the forum.

i was opened to the blog industry a year ago but i thought it was just personal entries. until recently a friend opened me to internet marketing and that gave me a more clearer picture of blogs and site purpose...

Social Media is a great source of Traffic if you know How to use them effectively. because I belive each social media site has it's own strategy. You have to understand that by being a expert user. When you will become a active member of any of the system I wish you will be able to know how to use them best for marketing.

I used to do alot blogging but u have to make sure the page rank of the blog u are posting.

I am also nvery new in the blogosphere, but enjoying it entirely. Information overload needs to be managed though. I have a blog (<URL SNIPPED>CRMtutor). The most important things in terms of SEM, and specifically SEO, are tracking and reporting. Test you way to success.
I contribute to other blogs (like daniweb!) and link building at this (early) stage and have looked at the bookmarking sites, but that still seems pretty daunting to me. I realise however, it is something of value (and also freely available) and therefore needs to be put in practice, then action. Currently, I have managed to use Facebook and Twitter to contribute traffic to my blog.
My 2c's worth, enjoy!
