I've noticed an enormous spike in pages indexed through WMT in the last week. Now I know WMT can be a bit (OK, a lot) off base in its reporting but this was pretty hard to explain. See, we're in the middle of a huge campaign against dupe content and we've put a number of measures in place to fight it. For example: Implemented a strong canonicalization effort NOINDEX'd content we know to be duplicate programatically Are currently fixing true duplicate content issues through rewriting titles, desc etc. So I was pretty surprised to see the blow-up. Any ideas as to what else might cause such a counter intuitive trend? Has anyone else see Google do something that suddenly gloms onto a bunch of phantom pages?
