The book I read to research this post was Promote Your Business Or Cause Using Social Media by Dennis Smith which is a very good book which I bought from kindle. This book which is around 170 pages is a reasonable length and a good introduction to this subject although if like me you are quite savvy about social media it might not offer that much new information. There is quite a large section on Facebook which is quite interesting and something I didn't know is if you promote a business or cause on a personal profile page which is quite common that is a serious infringement of their rules. Also if you have a page like a product you don't need to authorize every like button message you get which is the equivalent of a friend's request on a personal profile. There is a substantially shorter section on pinterest and this site boasts predominantly women users and apparently the average user clocks up 89 minutes on this site every month. The figure for Google+ is 3 minutes per month. Twitter is another powerhouse on the social media front with micro blogging which they call tweets which has now become a part of our language. I did quite enjoy reading this book and there is some interesting stuff on BlogTalkRadio where you can upload a podcast and there is the option of using the website which is free or downloading the software which you pay for but has additional features. There website is http://blogtalkradio.com.
