However for those who had 20 billion URLs, you must do the identical factor, redirect all of them, John added. However do not count on rankings to not change in any respect, rankings change with new URLs and new CMS platforms. So do not count on to see no rating adjustments when making CMS adjustments.
Right here is the place John stated that:
You are able to do 20 billion redirects. And sure, all website migrations / CMS adjustments WILL have an effect on search. It is a new web site, in spite of everything. You may’t change all the things and in addition count on all the things to stay the identical.
