I put up a post a few days ago about a test I was going to do with 6 different parasites. However, here's what I'm going to do now. In fact I've already done it: 3 Spamfinity packages (each package is around 6000 backlinks with social signals) 2 Spam Dynasty packages (each package is around 10,000 backlinks with social signals) 15 SAPE link from Daniyal (for high trust flow) 575 SAPE links from SpeedRank/t0mmy Doge-Links from T0mmy - the $167 package (this has lots of different kinds of links so it's great for link diversity plus it's got great reviews) A lot of people seem to have gotten success with one SpeedRank package alone along with t0mmy's Doge-Links. A lot of people seem to have gotten success with combining Daniyal's SAPE links with Colby's Spamfinity and Dynasty packages. Here they are - all pointing to the same parasite - Rebelmouse, with x3 Spamfinity and x2 Spam Dynasty. Worth nothing that the SAPE links too are from two different sources, both very reputable. Keyword is medium competition. Difficulty of around 68% according to SEMrush. I was able to rank a 75% difficulty keyword to position 2 on the first page using just SAPE links a month ago. Ahrefs reported around 500 links when it hit that spot. I have spent around $1500 on all the packages. Now let's see if this works. If it doesn't its sheer bad luck. Or it just means I went too hard when I could have been more gentle (with the backlinks)? I don't know. Let's see. As of now, the URL is not showing up for the target keyword anywhere in SERPBOOK. It is for some long tail useless keyword. But that's understandable since its only been a couple of days since these packages were ordered. Ahrefs showing only 9 links right now. NOTE: Pre 2014 May Update I have been able to rank for this keyword at will 4 to 5 times, with a 100% success rate using PBN's only.
