The last few days I was making pbn links for one of my websites. Always used the main keyword as anchor. I made about 2 links per day. Since last week the main keyword and another keyword went from the Top 20 to nowhere. All pages are indexed on Google. There is no manual penalty. I guess I made too much pbn links with the main keyword as anchor. So I deleted the last few pbn links I made to this website. I think it is not a regular Google Dance, since it seems like the keywords won't come back (I was waiting about 7 days, no movement of the kws). Should I give up on that domain and move the content to another expired domain?
