Are the ‘Facebook’ and other social media sites really help in promoting the traffic to a website?
Social Networking sites are great for traffic, but they are even better for building a following.
When companies use them for traffic, they tend to do it very poorly. They will have a post like:
Check out this great sale at www.mysalesite.com. 30-40% off most things seems crazy!
This is straight up, an advertisement and no body cares. It will actually hurt your authority because people will start to see you as someone that is just trying to sell rather than interact and help.
Instead you want to give them useful info, like point them to a review that points at your site. ( you can even write the review.. or pay someone to do it... like on squidoo or hubpages)
I actually reached SuN off of a newsletter discussing a topic on Social Media. This particuliar topic discussed other "social" avenues such as SuN. The article I am mentioning can be found here: http://www.openforum.com/idea-hub/topics/marketing/article/13-ways-to-network-beyond-facebook-and-linkedin-john-jantsch
To stay on topic.. social media when used effectively is great. Not only can it assist in directing traffic to your site/product/service.. but it is also a great way to establish/maintain brand recognition. Another big point, especially with a startup is that many of the social media sites are free and give you access to endless amount of potential customers.
twitter and FB have both been instrumental to my success. when possible, link the sites and get more bang for every bit of effort. for ex, i have my FB and TW linked. all blog posts are distributed automatically to FB, which sends a tweet to my twitter account
