Webmaster Forum / ColdFusion / Getting Started / November 2007Missing Dynamic Pages and SEO
Hello I have a details page that takes the URL parameter Product-Code and displays the details for that product. Now what happens when I remove a prduct from the database and that URL still exists in the Search Engine indexes. I noticed that even though the product code doesn;t exist anymore the page still executes and shows all blank information. So basically I'm going to have all those old product pages in search engines with no info and run teh risk of duplicate content penalty. What shoudl I do. The site is programmed in CF. You can see what I mean by visting the site www.juniorbaby.com and click on a product and change the product code in the URL. The page will load with no info. I feel my ranking has been dropping and this might be the problem. The serach engine must think all those old pages are all the same. Any help would be greatly appreciated. Pete Detect that the product code no longer exists and display a message saying such to the user and the search engine. This would be much friendlier then a blank page. Wouldn't this cause the search engine to believe that the product page still exists. Inturn causing all my old product pages on the search engine to seem identical? How could I let the SE know that this page no longer exists? I just don't want the SE to have lots of pages indexed that no longer exist and have the same title, desciption, etc... The SE will eventually update their content to the error message content. What you may want to do is update your "robots" file so spiders will not index that particular page at all. They will just get their links from the links in the site then, and not actually spider that page any longer, error code or not ... eventually the page reference will disappear from the SE. Just a thought. What if I checked if the product existed and if it didn't I would add a< robot noindex> tag in the header of the page. Would this cause all my details pages not to get indexed. Meaning if details.cfm?PID=1234 doesn't exist and I instruct the SE to not index the page would that cause the SE not to index my other valid details.cfm?PID=validID pages. Any help would be appreciated. 1) SE != spider : some spiders follow rules you set in meat tags, robots.txt, rel ttributes etc, others do not. 2) <cflocation> tag basically means http code 301 "temp moved" (or is it 302?): in cf8 you can set cflocation to return 301 or 302 code (temp/permanently moved, whichever one is which). 3) use cflocation inside cftry/cfcatch (around retrieve product details query) block to redirect your users to a full products listing page 4) google webmaster tools lets you request removal of a url from google's search index - do that. if you are not using google webmaster tools - shame on you! --- Azadi Saryev Sabai-dee.com http://www.sabai-dee.com |
