Welcome to the Q&A Forum

Just recently we did a redirection from a website that is ranking very well.  The redirection was done through redirecting the page of the website A to the related page of website B.  Website B raked massive traffic in the first week and have increased its ranking among Google searches but recently the traffic seems to decline.  Website A which was ranking very well before redirection is now nowhere to be found on Google search. Is this a consequence of doing redirection?  Please help.
