REVIEW:
My order was placed on 10/5 and completed on 10/19. I was told to wait ~5 days for SERP changes, so now that it is the 24th, I feel comfortable writing a review.
The Good:
Article quality is good, KW is used naturally in the body of the content, and each post has an image associated with it. It was very important to me to get uniquely written content (not just spun), and that's exactly what I got. In addition to looking like a quality backlink, I see no risk of having the content taken down due to spamminess.
I submitted 6 KWs and 2 urls, the KWs ranged from easy to hard in difficulty. My easiest KW started at #3, moved to #1, and held its position. My medium difficulty KWs started at #9 and #15, and have hovered around there mostly (they are at #11 and #18 today, but were #9 and #14 yesterday). My hardest KWs never broke into the Top300, and would probably require a larger package (I ordered the smallest) to see an effect.
Since I started this campaign, my daily traffic has more than doubled.
The Bad:
One area of concern for me is that I have also been tracking some other closely related KWs on these pages, particularly my most profitable one (which I intentionally did not use for this campaign). This is a medium difficulty KW and initially went from #9 to as high as #6 two days ago before dropping to #12 and #11 yesterday and today, respectively. I am hoping to see the page recover its Page 1 position, and expect that this is just a Google dance.
All in all, this service does what it says on the tin. Unique content that is easy to read and obviously handwritten. For the price, I am pleased with the value I received and look forward to further SERP improvements down the line.
Rating: 9/10. Best of luck to you in your sales, howard_hughes!
