I'll be the first to admit that i am newbie when it comes to this stuff. I have tried to rank a website for a local business with relatively low competition. After about 6 weeks I made it to rank 12 for one of the key words and rank 20-22 for the rest of them. I didnt know much about keywords so when i pulled up my competition on SEMRush, i noticed that my competition had like 250 keywords and they were the number #1 spot for quite a few of the highest traffic ones. I only had like 8 keywords according to SEMRush. So i thought, I'm a newb and i need to immolate what these guys are doing. So that's what I did. I took around 100 of the keywords that my competition was using and added them to my website. I am also using a 15 website PBN and RankerX web 2.0s as my tier 1s and then I GSA spammed for my tier 2s. Also, I'm pretty sure i didnt do everything right when building my PBNs (first time doing it) but I did all the obvious stuff, like only hosting 1 website per server. Using different names for every single one. After i did the keyword update on my website my rank went from 12 to 42 on the keywords I had already ranked. Is this common or did the big G discover my PBN and penalized me?
