It’s funny, people that are these SEO, Social Media, Internet Geniuses, whatever people are full of it. They think that they know it all and refuse to give others any credit and they are wrong and give incorrect info out. I’m no guru, not a genius, not the best but I know that most websites don’t need you to type www. before the domain. I know what permalinks mean. I know about The INTERNET and I can help you learn. I don’t charge much 
Seriously, these “internet specialists” are a bunch of misinformers and are NOT who you need to hire to teach you or market for your company.
Here is an example of bad web development. http://state.nj.us does NOT work, but put a www. before the state and it does. So, Chris Christie , maybe your Social Media dude that you hired should fix that. What do you think?
