Review of SERP Launch
OK, sorry it took so long for a review, but I wanted to make sure I had some time to sit down and write a proper review as this is a high quality service.
For the most part, I am very pleased with this service (Note: this is a paid review). I placed my order and received my report in about a day. Very impressive turn-around.
What I Received
111 do-follow wiki links
12 EDU wiki links
350 no-follow wiki links
A massive list of over 40k trackbacks to the Tier 1 wikis
Over 700 social bookmarks pointing to the do-follow wikis
Analysis
I LOVE the link diversity and think it's important to have a good ratio of do-follow to no-follow links. The quality of the content on the wikis is OK. It's not jibberish, but (to my trained eye) obviously spun. I think that the content is good enough to stick on the wikis, though. I checked about 30 of the do-follow wikis at random, and checked all of the EDU wikis, and they are still there.
Results
As far as results, it's interesting because I used this service on a site which was recently penalized. I threw some Xrumer links (stupid, I know) at one of my sites. Hard to tell if the site was penalized or just dancing, but I have seen sites never recover from Xrumer blasts before (the site wasn't sandboxed, as I could still find it on Google, just not for my kw's). That being said, my site is now back at #4 and #8 for my 2 main keywords (local, general keywords). I won't make any guarantees that this service will help get your penalized site back to page 1, but it seems to have done the trick for my site.
Conclusion
Overall, I would definitely use this service for any site that needs a good foundation of links, especially for expanding link diversity. This is a safe service that won't get your site raped by Panda. Zingo's communication is great, and the turnaround time can't be beat. Buy this, add some content to your site, and watch the magic happen!
I will try to follow up with any changes in rankings over the next 2 weeks.
