REVIEW
DD offered me a review copy of the Rapstar package. I've been using his services for months now, and have been extremely happy with them - I'm pretty sure they're the best value (which means best results for the money, not just best price) on BHW. He also has incredible reports - as mentioned previously, you really could provide them directly to your clients. So when he offered me this review copy, I jumped on it.
I should point out that I used the smallest package, and I still split it over 2 websites. I really wanted to see what it could do. Both sites are for medium-competition local keywords in the same niche, but different cities (competition level for both cities is about equal). Both were hit by Penguin when it first came around, and I set them aside and focused on other projects, so I hadn't done any other SEO on them in a few months. The reason I used 2 sites was because I wanted to compare different keyword mixes (after all, these were hit by Penguin - too many exact-match keyword backlinks).
Site 1:
I honestly didn't expect much of anything from this site. I took a penguin-hit site, and pushed more exact-match keyword anchor links to it (16 different keywords in all). The package proved powerful enough to give me some results, though - several of my biggest-money keywords moved up at least a page or so. One of the very biggest actually went from nowhere to 42 - not bad for half the smallest package. And this was by doing everything wrong - really, I was making my penguin situation worse, but the links were good enough to give me a boost.
Site 2:
This is the one I was really interested to see the results of. If site 1 was the control, this was the experiment. This is where I was really going to test its claims as a portfolio balancer. I provided 119 keywords. 5 were my actual keywords, the rest were all completely generic anchor text. So how did half the smallest package do with this penguin-busting task? It killed it.
Below are their ranks before I submitted this order, the ranks the day after I received the report (about 2 weeks ago), and the ranks today.
KW 1: 60 > 34 > 46
KW 2: 61 > 32 > 38
KW 3: 61 > 36 > 34
KW 4: 100+ > 100+ > 53
KW 5: 48 > 37 > 34
As you can see, lots of movement, a little dancing after delivery (as expected), and some excellent end results. Of the ~40 (I know, overkill) keywords I'm tracking for this site, they all ended up an average of 21 places higher. And remember, this was with half of the smallest package.
Remember, these results are from sites that had already been hit by penguin. You'll have much better luck with exact-match keywords if you don't already have a penalty against you. Use common sense - when you order, use the right keywords for your situation. The fact that you can use so many keywords with this product is what can really make it a penguin-killer.
TL;DR: Portfolio balancer: yes. Penguin buster: it would appear so. Will I be ordering from DD again? Try and stop me.
