Canonical nightmare! Help!

[JM67]

Hi all, I really hope someone can help, I'm new to Moz and think I've done something really silly.

Last night I changed some settings in Magento for how it handles Category paths and Canonicals to those that most SEO people recommend. Everything looked fine and products that had 4 URL's all seemed now to have only one.

I then tried the dropdown menu on iOS and it just didn't work (worked fine on PC). In a panic I changed the settings back, cleared cache etc...

Now I try to grade a page in Moz and I'm scoring an F on every one, critical errors everywhere! Top of the list is that it's returning HTTP code 200.

Has anyone heard of navigation that can be broken on only iOS or can anyone shed any light on how the canonical changes could have affected navigation?

Thanks, any help or suggestions really welcome.

I'd have to assume the changes in Magento broke your site because adding Re="canonical" tags wouldn't have done anything like what you're describing and with such intense speed considering you did this the other night.

Also a 200 HTTP Status is the Response Code for OK... which is what live and functioning pages should return.

JM67,

Mike is probably on to something. 200 status is usually followed by OK which means you are good to go.

I would suspect that you may have a different issue when it comes to MOZ page rank. When you go from a good page rank to an F rank It usually means your are somehow linking the wrong  Keyword to the page. So in your case check for something as simple as having "HTTPS" vs "HTTP" or www version vs non www. That makes all the difference.

Yeah, a status code of 200 is generally a good thing. Could you direct message me through the site and tell me which campaign you're seeing the errors on. I can log in and try to take a deeper look.
