I have been promoting a forum named WDP Forum. Whenever I make search with google writing WDP Forum then the forum appears on 1st position on 1st page but when I click that link then google take me to http://www.websitedp.com/archive/index.php this link. I am not getting that how google took this link? I am using Mozilla firefox.
I just did a Google search with "WDP Forum" and your site is nowhere to be found. However when I go to the archive link you provided, then click on the Full Version, your unarchived site comes right up.
Yes you have been affected by google cookies. Because you have been to that site google thinks you are interested in that site and lists it for you. You need to make sure you are not logged into google and clear your cookies. Then search again and you will be able to see what everyone else can see.
My site hasn't on first page or on position one. Sometime my site is seen on first page and sometime it shows on 2nd. My position with the keyword WDP Forum is not fixed.
I'd guess that in your forum settings you have it that Search Engines are supposed to index the archive version of the site.
I found your website on page 2 of Google and when I click on the link I go to http://www.websitedp.com/index.php Have you solved the issue then?
You must check in webmaster tool is there any malware attack or any issue with your site . You can do reconsideration in webmaster tool and google will reconsider in some days. Might be it help you to get your site back .
