I have had a lot of experience with penalties this year, and I have a few websites that have been hit, and recovered. During my research I came across these articles explaining how Google treats 400 level header responses in regards to link juice and signals. Let's see if my test proves these articles to be true. [h=1]Want To Disavow Links In Google Now? 404 The Target Page [/h] HTML: http://www.seroundtable.com/404-links-google-15427.html [h=1]Google: Spam Links To 404 Pages Won't Hurt You [/h] HTML: http://www.seroundtable.com/google-bad-links-14660.html The scenario that's playing with me right now, is I went a little heavy with a linkbuilding package on a new url on an older site. Not nearly enough diversity in my keywords. Soon after the links were built, the entire site dropped in rankings. What I've done is, copied the new page and duplicated it on my site with a different url of course. And then deleted the old page and made sure that it returns either a 404 error, or 410 error. Not sure if it matters which one. Make sure to change any instance of your internal links pointing to the old url, and also make sure wordpress isn't automatically redirecting the old url to the new url. I know a few seo plugins that do this on auto. I'll see in a few days to a week if it makes any difference to have completely removed the page that is causing the penalty for my website. In my case it's nothing to drop the penalized page because it's new and I have done no linkbuilding except one package. If you have a very valuable page that's been hit, I suggest doing the same thing except maybe keep building diverse links to the 404 url, in hopes that some time down the line you can reinsert that url that you've spent months/years building links to. Has anyone ever tried anything like this? What were your results?
