Hello all! I have a very -very- strange serps behavior of a website. This website have some good serps like main keyword #12 , secondary keyword #3, other keywords #3-5 etc.. Main keyword is homepage and all the other subpages. The website have links from private pbn , authority links from sponsored articles and other natural links to our articles. On around May 17(around that month google update) our website drops.. Drops mainly for the main keyword which is now dancing around page 3 and page 6. Also, some times in the serps there isn't show the mainpage( which is the one with the links) but some subpages which doesnt have links neither the content is similar!! The rankings of subpages havent affected or affected a little bit. For your reference : around April we install ssl and do 301 from http to https, google speed is over 90 and the links are good variations with exact,brands,naked,lsi.. What's your thoughts? Onpage issue? About what?
