/page/4/?c=1-211609

What is the '/?c=1-211609' and why does it exist in that URL?

Recently, I've been noticing pages getting indexed on my blog that end with random strings such as what I pasted above. Where do they come from? How do I stop them? So far, I've been using the Redirection Tool to simply redirect /page/4/?c=1-211609 to /page/4/ - because I'm worried about potential duplicate content from these strings.

Any help would be greatly appreciated!

"?c=1-211609" is a query string that passes data in php.

But why can I visit /page/4/ and then /page/4/?c=1-211609 then?

What sort of data is it?

Anything after the "?" question mark is data that for instance may be used for tracking.

I don't believe that Google sees the pages as duplicate content. Many sites use the data as tracking codes.

I'm not sure what kind of data it is. Perhaps the site has been hacked.

Did you notice that when you do that query in Google almost all of the pages have some reference to "Legend of the Green Dragon"?

inurl:/?c=1-211609

The odd site in the bunch is your Running Online Business site.

I don't know what the relationship is, but there is some connection. You might want to check your server logs to see if a site with a domain related to Legend of the Green Dragon shows up as a referrer.

Legend of the Green Dragon? I have no idea what that even is. :P

This is very strange!

Good idea. There's a great chance that this is the case.
