So I check ahrefs every day to see how my site is progressing. I checked it on Monday and all was looking fairly normal, but something weird happened between then and last night: - My backlinks jumped from 66 to 120, most of which have the anchor text of my main keyword. - My "404 Redirected" plugin on Wordpress shows that there are about 240 new URLs showing up (e.g. people are trying to access URLs that don't exist and they are being redirected to the main page) These URLs do not exist on my site, although I happen to know that my domain was used before; they appear to be from that old website that used to be on it. What's the deal with this? Somehow, ~80 backlinks to old URLs from the previous site just get indexed overnight? I guess it's a good thing to have more backlinks, but does anyone know specifically what happened there? Thanks.
