Businss...online market?

How can a business best use a Web Site, Facebook, a blog, Flickr, YouTube, and Twitter to create an effective online marketing campaign?

            A business can use a website to have a effective marketing campaign due to the users. Many people use those sites to talk, chat or even video to each other. Some people use you tube to blog and use it to show reviews of products or leak products or even explain the product that is going to be coming out. Any one can have an effective business threw these sites by reaching out to their audience and having ads in the most popular web sites like gaming sites or social networks. I know from personal account that when I use the online market website Ebay.com I also use youtube to see reviews of the product and research if its real and worth buying. I also keep my eyes out for reviews and actual peoples personal reviews to see both sides of the products effect.

what not to do.

Do not use random colors.( have  a nice color scheme that matches and is not hard on the eyes.)
Do not use mystery meat navigation.( weird navigation is confusing.)
Do not try and fit as much info as possible and not make other pages to that website.
Do not use crazy fonts.
Flashy colors are a no no.
Do not throw in random pictures or videos to take up space.
Sideways navigation is confusing.
