WP Plugin: DupPrevent DupPrevent WordPress Plugin helps you avoid being penalized by Google for duplicate content by inserting NOINDEX meta tag in pages that might trigger Google’s duplicate content filters. Plugin also contains a robot.txt file to disallow spider access to files that need not be included in engine’s index.
What a cool idea for a plugin. I see much of my content duplicated since setting up redirects from my old numeric URLs to my new word-based URLs. Can this plugin help with that? Maybe I’ll just install it and see. 🙂
Technically there isn’t a need for that so long as you use redirects.
Anyone that uses mod_rewrite or a redirect php script (such as Scott Yang’s Permalink Redirect) shouldn’t need to worry about Google penalizing their site – just make sure you use 301 (permanent) rather than 302 (temporary) redirects. However, that’s just SEO, you won’t be actually punished for it.
Google only punishes duplicate, non-redirecting content. Anything that redirects is safe.
Therefore, this plugin is useful for those *not* using Scott’s excellent plugin, and have multiple permalinks (that don’t redirect) pointing to the same exact content/post – don’t need to use it otherwise.
Hi, I downloaded your plugin but after enabling it, my page would not validate as XHTML 1.1 so I poked around the plugin a bit and after reading some parts of the XHTML 1.1 standard it seems that the meta parameters must be given in a certain order. This is how the plugin should add the meta tags if you want to use it in a XHTML 1.1 compliant document:
$robots_meta = ”;
} else {
$robots_meta = ”;
Honestly I don’t know if I’m better off running this or not, but I do know I use mod_rewrite and I have a lot of duplicate entries in Google. My 200 pages are some 500 results. UTW Tags are responsible for a lot of bulk, which I notice this plugin marks as NOINDEX.
Seems worth a shot. I’m all for a lot of results, but I’m not trying to spam Google with content already listed.
