That's why it's necessary to always stay abreast of developments in the SEO world, so that you can see these algorithm updates coming or you can determine what to do once they’ve been released. The WordStream blog is a great resource for SEO updates, but we also recommend Search Engine Land and Search Engine Roundtable for news on updates. Glenn Gabe of G-Squared Interactive is also a great resource for analyzing the causes and impact of algorithm updates.
I am actually using a free service called Cloud:flood created by Glen of the ViperChill. I had great success with it, making a file available for download (I shared a list of 140 blogs worth following). It has two options, a person can RT the download that will take new people to a post where the download is (or what ever landing page you want them to come to) or they can share it on Facebook instead of tweeting it.
Direct traffic is defined as visits with no referring website. When a visitor follows a link from one website to another, the site of origin is considered the referrer. These sites can be search engines, social media, blogs, or other websites that have links to other websites. Direct traffic categorizes visits that do not come from a referring URL.
