I don't understand the question, and even moreso do not understand the answer by the second poster.
Please elaborate and we might be able to provide you with a helpful answer.
Ok. And I know this has been covered before, but I just got a little panic, so wanted to run past. I may need to better understand what is viewed as a "duplicate page" by the engines. Before I clarify, is it correct that a website can be unindexed if it is displaying pages that have the same content on them. In my search tonight in this forum, I cam across a thread where a person mentioned that a website had this problem - where they were ranking well, and then lost all rankings and it was because of duplicate content on that website. The person removed the duplicate content, and rankings eventually returned.
I can certainly understand why pages with the same content on them, on the same domain, would be viewed as a bad thing. It's just not helpful to the reader.
That said. If this is in fact true, what makes a page? We have an asp/SQL website, where content pages are identified with a 5 digit number. The menu/navigation and content manager were custom built, so we had to think through how to make our menus work to 1. pull the right site style and 2. open the correct left hand navigations. These details aren't really that important, except to know that there are 3 ways to get to one page on our site. Of course, we didn't set out to purposefully have 3 urls going to one page (which pulls that article page that is IDed by five digets), it just turned out that way after we customized everything.
So, these URLs all go to the same place:
/article.asp?ClickedLink=293&ck=10212&area=27
/article.asp?ck=10212
there is a third, but I can't remember it. It's some form of the above. When we are internally linking our content, we use /article.asp?ck=10212. This produces the correct left navs to open to the correct sub page when you click on a text link. However, when you get to a page by clicking on left menu, you get the first and longer example. The sets of numbers stand for the specific left menu, then the article, then the main section which has a color theme assigned to it.
Sorry that was so long. Would these URLs constitute as duplicate pages?
Further, if you have http pages, and those pages are also available as https pages for the same site, do those count as duplicate pages.
Perhaps all of this is a non issue. Thanks for reading!!
