I remain sceptical about the effectiveness of SAPE post Penguin 2.1. Whilst I realise that people are saying the update is still rolling out I am of the belief that Penguin 2.1 and hummingbird in combination may be more of a dynamic update that rolls on indefinitely. (just my own theory based on how encryption has evolved over the years from static encryption keys into something more dynamic that rolls daily, weekly, etc) Back to my SAPE conundrum I purchased the SAPE services through a seller on BHW. I have used the seller before. I had a 4 year old website with very little PA/DA (it was barely a PR1 site). It had 10 pages MAX. It had no other back links apart from SAPE and some blog commenting. I would throw 65 SAPE links for a particular keyword and within a month or so it sky rocketed to Page 1 for the targeted keyword and other relevant keywords and stayed there for at least 3 months until it hit the manual penalty. (I'm happy with that strategy to churn and burn). I used a similar strategy for dozens of websites and they all worked equally well. Since this particular site got hit by the manual penalty I had another site ready to take over. The new site was an aged domain (nearly 8 years), had a few old back links (nothing major though), and has a variety of interesting articles with lots of engaging content (all written by a professional). I have thrown 125 SAPE links for a particular keyword and I can barely get it to page 1. It's hovering around page 2. I decided that I will not diversify link building to much after penguin 2.1 considering that less is more seems to be the new way. So naturally I also decided against any tiered link building because of my own conspiracy theories about hummingbird and my belief that it is more than just a smarter search engine.. rather a more dynamic spam analyser (my delusions drawn from the symbolic characteristics of an actual humming bird and it's ability to fly backwards?. metaphorically speaking I translated that into saying google will look deeper into the links in backward tiers. Okay moving right along, so it's a 1.5 months into my SAPE campaign and I'm struggling to get to page 1. The competition has not changed significantly. I employed a churn and burn strategy before but I can't seem to get it to work as well as before. Do I need to diversify my links considering I never really did that before and still got results? Based on my own experiences I can only conclude that SAPE links have lost value significantly. I am interested to hear of other people's experiences with SAPE post Penguin 2.1.
