  Parmveer Singh Sandhu: I've a strange issue with my keyword rankings, I would highly appreciate if any SEO Expert would help me.
  
  Earlier the pages from my site were ranking well (almost top) but now its appearing like there is some problem in google's algos. ;
  
  Check ranking using moonsy[.]com/google-keyword-rank-checker/ tool. ;
  
  E.g. for keyword A, page B is ranking; for keyword B, page C is ranking ..... ;
  
  check for keyword 'internet marketing course in jaipur' & url quibustrainings[.]com irrelevant page is ranking
  
  why this is happening, can anybody suggest? And its happening with all of my keywords
