Welcome to the Q&A Forum

We are re-launching a client site that does very well in Google. The new site is on a www2 domain which we are going to send a controlled amount of traffic to, 10%, 25%, 50%, 75% to 100% over a 5 week period. This will lead to a reduction in traffic to the original domain. As I don't want to launch a competing domain the www2 site will not be indexed until 100% is reached. If Google sees the traffic numbers reducing over this period will we drop? This is the only part I am unsure of as the urls and site structure are the same apart from some new lower level pages which we will introduce in a controlled manner later? Any thoughts or experience of this type of re-launch would be much appreciated. Thanks Pete
