Wanted to post a review after giving these links a couple of months to see what they did. I ordered the "Basil" package, which is 20 links for $159/mo, and I got a discount code, which made it about $146/mo.
I placed the order on the 5th of the month, and the order wasn't completed until the 25th, which was a red flag for me. If this was a large package, once could justify drip-feeding, but for 20 links, I would expect a quicker turnaround...especially on a monthly-billed package. My first thought was that they may delay the delivery so I don't have time to evaluate any impact before I get billed for month #2.
I placed the order back in November, and simultaneously placed orders w/ other sellers for other URL's (on the same website with similar competition) for about the same price. This package is literally the only one that I didn't notice any measurable movement on. And, if anything, it was the easiest of the 4 URL/keyword combinations that I tested together.
So, for 3 months of billing, I'm down about $450 and have not seen any results or impact from these links. I have cancelled my subscription today, so as not to waste anything further. Others may have better experiences, but this is just my personal feedback on what I saw with my own order.
