Hello guys. I did KW research and found a very easy to rank KW. After writing a very detailed 2000 words post on that I published it on my blog with PA 25 and DA15. After two days the post got indexed and got ranked at 20 straight away. Afterwards I posted two or three manual highly relevant blog comments to see where things go. SERP rose to 19. It then started moving in between 20 and 25 (for four days) and finally got settled on 24. Then I got a no follow link from EXAMINER.com and SOCIALMEDIATODAY.COM from somebody. The content was high quality of-course as they wont allow low quality content. Links got indexed almost instantly but it has been two days since those two links were indexed but no SERP improvements. The post now stands at 25. I created this thread to get some answers from experts who follow google algos closely. Has google got slow with SERP updates? Can I expect to see some improvements in near future? Am I doing anything wrong here with these links? Please can somebody answer? and give expert opinion?
