Hi All, We lost a lot of good rankings over the weekend with no obvious cause. Our top keyword went from p3 to p12, for example. Site speed is pretty bad (slower than 92% of sites!) but it has always been pretty bad. I'm on to the dev team to try and crunch this (beyond image optimisation) but I know that something I can effect is the number of 301 redirects we have in place. We have hundreds of 301s because we've been, perhaps incorrectly, adding one every time we find a new crawl error in GWT and it isn't because of a broken link on our site or on an external site where we can't track down the webmaster to fix the link. Is this bad practice, and should we just ignore 404s caused by external broken URLs? If we wanted to reduce these numbers, should we think about removing ones that are only in place due to external broken URLs? Any other tips for safely reducing the number of 301s? Thanks, all! Chris
