The thing about using all these platforms to market on is it takes time. When you take the time to do it of course it can lead to great results. I have 2 other Blogs beside this one, One twitter account, plus I use Twello to gain more followers, FaceBook, StumbleUpon, Press Releases, Forums, Directories etc.
The only optimization I have is using the same keywords and correlating links. when I update these, I cannot track how each link or keyword performs except for the only analytics I have on my host control panel. I cannot see what long keywords or keyphrases are attracting the most visitors or what the most clicked on links are on these other inbound markets. I use Google analytics, but that is good for my own site.
so I have resorted to a Inbound Marketing Software called Hubspot. They make all this simple for me. I can optimize each keyword, or keyphrase for my blogs and site, get true analytics, and even handle my leads all with their simple to use easy software. I have signed up for their affiliate program because I believe in their software. Give them a try for free!
