Rosetta Code:Village Pump/Google

It looks like Google is returning weird results. I typed in "powerbasic" (because I'm too lazy to do it right) and, while the first result is correct (PowerBASIC), the second is decidedly not correct: instead of PowerBASIC/Omit, it links to villagepump.rosettacode.org/wiki/Category:PowerBASIC/Omit, which is (of course) 404. (Actually, many of the results are to villagepump.rosettacode.org.) Something just ain't right... or is this expected behavior? -- Eriksiers 00:14, 3 October 2009 (UTC)

To be clear, you were using Google? I tried a simple search, and I saw what you're referring to. It looks to me like Google didn't stop crawling links to villagepump.rosettacode.org, long after that subdomain was dropped. (It used to whole an SMF forum install.) My best guess is that those "pages" were indexed between the time the subdomain was dropped and when I set up the redirect of (x).rosettacode.org/y to rosettacode.org/x/y. It's possible the DNS components weren't dropped (or were cached), while the virtualhost directives on the server no longer trapped the subdomain. If they were trapped by the default domain, and the default vhost served up rosettacode.org/ content, then I could see how those pages would get indexed that way. It doesn't really make sense why GoogleBot wouldn't have figured it out; I'm serving up the correct headers for the error code. And I'm using 301 permanent redirects for the redirect from the subdomain. Might be time to try setting up the sitemap again. --Michael Mol 05:22, 3 October 2009 (UTC)
