Once the redirection is life, it is normal for the first week the traffic to Site A to increase. However, you need to keep in mind that this may be a false alarm only. In our case, it was hardly the result of visitors clicking on Site B’s URL before Google has an opportunity to demote them. For the next two weeks, we’ve experienced a decrease in the organic traffic which means that we’ve experienced no significant advantages from the move.
It is possible the traffic from Site A would decrease anyway, without doing the redirection because of the competition, algorithm updates, and etc. The point is that the redirection was not worth doing.
However, an interesting fact is that the average bounce rate for Site A, after a few days after the redirection increased by almost 10% over the following two weeks moved back down to the point where it was before the redirection. If you stop for a second and think about it, it makes sense. The visitors were clicking on Site B results and they get redirected to URLS that were irrelevant which exaggerated the bounce rates. That is why the Site B has resulted in lowered rank and the bounce rate returned to its normal point.
This is the best way to demonstrate the redirection of a website to a new domain, it would be totally impractical to explain in any other way. Usually, the outcome of redirecting a website to a new domain with different content is the same, including the URL redirections within a single website, where the website owner does not actually understand the procedure or the disadvantages of the process.
