Hi folks, I have a site that's was ranking #3 for its intended main keyword. It was pretty stable for the last 3 weeks, with just 1 PBN link and 1 random blog comment link. I added a new PBN link 2 days ago, and within 24 hours the ranking has dropped to 6 or 7. I created the PBN site, which looks legit etc. and put the link straight away. Got the PBN site indexed into big G and then bam, hit. Is this a usual procedure of the big G, or something more sinister? The PBN domain was never used for spam and it is very relevant to the niche. I kinda want to remove the link to see if it improves my ranking, as I'm losing sales, but at the same time perhaps it's a temporary glitch. Any advice appreciated, thanks.
