One of our employees is responsible for “tweeting.” The Youtube channel has also proved very successful.
I recently bought cabinets, and maybe because I work for an online retailer, but I chose the cabinet company based on price and quality, but also based on their website and especially because of their youtube channel which took you through the process of ordering, measuring up your kitchen, installing the cabinets, etc.
Blogs are also powerful marketing tools. Our customers are really into the blogs and they send comments and photos of their completed projects (I work for a retailer that sells to DIYers.)
We offer special coupon codes, online specials, and other things through all the online marketing...it brings customers back to the site on a regular basis.
Twitter is also great if you’re a conservative news/blog junkie, or even just a news junkie. BNO News breaks current events on their twitter feed 20-30 minutes before anyone else and it’s pushed onto my desktop. I follow Michelle Malkin, Allahpundit, and a bunch of other great conservative voices.
@chuck_dizzle is hilarious, you have to follow him. :-)
