Rebranded a client site last month, old .pl domain to a new .com. Same content, same structure, we set up 301s from every old URL to the matching new one. Or at least I thought we did.
Three weeks in and organic is down around 40%. GSC on the new property shows pages getting indexed slowly, and some of the old URLs still show up in search. The change of address tool was submitted on day one.
What should I be checking first? Is this just the normal dip or did we screw something up?
