Here is my review of stans service: In the first sentence of the ad crowdio links are supposed to be "Niche relevant discussions". When I read this I thought wow that's cool so it will look really organic and white hat, no worries here. Comments should be 200 symbols (characters), NO spammy sources, and niche relevant LIVE discussions. Right so now that we know the criteria, lets review what was done. All links are high DAs and TFs (except two with low TFs a 6 and 3, all others 10+) as promised, no problems there. DA average of 53.5 TF average 25 3 links included were already deleted but as stated are guaranteed for 6 months so if he replaces no worries there. 1 link had nothing to do with my niche and was on a hair loss thread - this is a bit bothersome because that looks spammy and unnatural 1 link was on an article and is a blog comment - mistakes happen 16 links came from relevant niche threads (he included 21 links in the 20 post pack) Pretty good mix of discussions, the comments seem relatively natural. For the do follow links, they'll definitely pass juice. I did cancel the monthly service and just did month 1. I'd like to give these links one month to index and see how they move my ranks (if they do at all). I hope Stan can shed some light on the deleted links, non niche relevant link, and the blog comment. Mistakes happen, to me it's not a huge deal, but I hope it can be dealt with in a swift manner. Thanks for the service Stan. Cheers.
