I'm not sure what blogs you have been to Admin but the ones that I frequent are pretty awesome, full of useful information. Of them all, my favorite one has to be this one:
SmartPassiveIncome blog- This isn't exactly an Internet Marketing blog but it has more information about IM than any other blog out there. The thing that I like the most about this blog is the fact that the blogger -
Pat Flynn, posts from a newbie's point of view, with all the trial-and-error involved. It gives you an opportunity to step into his shoes to and learn things as he did.
Thing to look for: Search for this topic called
Niche Site Duel. You can find it on the blog's right sidebar. It is full of information about backlinking, marketing, etc. - super useful!
