Sorry this took longer than expected, I should have gotten this done earlier. My review and examples of Dripable
Back in 2011, I took the keyword classic cars for PR4 website from page 18 to page 2 in google for the keyword classic cars and muscle cars
by only using dripable links. I shot them straight to the money site, and was actually just running some tests. The results were amazing, on autopilot was able to get to page 2 in google for a very hard to rank for keyword. I really think the PR of the website had a lot to do with it, but still, that shows you the previous power of these links.
However doing that today will probably get yourself a link velocity penalty and or a serious penalty, I don't even think the owner would recommend using these links to your money site now. But these links are Extremely effective as part of 3 tier seo strategy.
Lets look at my keywords for a PR1 site in the most competitive insurance keywords on the internet
My dripable account was reactivated on July8th since then I have seen 20 to 60 point positive jumps in my keywords, and like I said these are very very competitive insurance keywords, that you can confirm the difficulty using Ultimate Niche Finder, by Clyde an amazing keyword tool.
I expect my keywords to keep showing positive ranking increases as I keep using new and high authority tier2 links and then keep pounding them with dripable links as my tier3. I am also currently using backblasts (terrible name) and can't report any impact yet, as I haven't set up my account correctly, thus I can't measure their impact yet, but I can say both back blasts and dripable have great support and I have used dripable for a long time and can easily measure its impact on using a 3 tier link strategy, hope this helps.
