You can see a half dozen or so reviews I've left for Leith on his Spook SEO thread and you can tell how much I love his work. If you look at my review history, you'll notice I don't leave reviews on threads where I don't really like the product and nobody ever gets a second review when I don't love the product.
I say that because what I'm about to say should not be taken lightly. In fact, for the first time ever, I really don't want to leave this review because I don't want my potential competitor's knowing how well this service works. Alas, my core belief is that the more you give the more you receive so here it is.
I took on a new client that had a penalized website. I did A LOT of work to this website to clear the penalty. First I got it back into the first 10 pages. Then page 7. Then page 6. Then page 5. Then page 5. Then page 5 haha. That damn website just refused to move up!!!
It was a pretty darn competitive term I was going for. And trying to rank against websites which averaged 10+ years of domain time and several hundred to a couple thousand very high quality backlinks.
Needless to say I put Ghost rank on it and within 35 days it moved up to PAGE 1 #4!!!!
Now, to be fair, there was a lot at play here. I spent a lot of time and money to make this happen and Ghost Rank was not some magical pill that fixed all of the problems over night by itself. However, it wasn't just coincidence that the website suddenly leaped in rankings. And to be ranked in the top 5??? WOW! As we all know that's when competitive keywords really get competitive.
This service is not cheap. Thank goodness! It will keep the "weekend warrior" at bay which in my opinion is a good thing as that helps keep the quality higher. I spent a lot of time with Leith asking questions about this service. My #1 priority is always the safety of my customers website. I don't care if I get on page 1 for 3 months if the website has a major penalty that knocks it out of the top 10 pages again 4 months later.
After having all of my questions answered, in addition to knowing Leith has proven time and time again to do incredible work and care deeply about high quality lasting work as well, I took that leap of faith and my gosh did it pay off!
Would I recommend this service? If you are an experienced SEO person who has the funds and a strong off page and on page base established on your website, HELL YES!
