Hey there i have coded a plugin for vBulletin 4 that prevent thin content. This mod will add the meta noindex tag to threads with a word count equal or below the setting you specify. For example: The word count within a thread is under 200 words and the thread is older than 60 days, the <meta name="robots" content="noindex, follow"> tag will automatically placed in the header. When someone post in the thread and the word count is higher than 200 words the <meta name="robots" content="noindex, follow"> will removed automatically. That will increase time on site and page views per visit. Websites with shallow content aren't helpful to searchers, so as a company trying to promote the best search experience possible, it makes sense that Google is trying to ensure only the best content is surfaced in the SERPs. As for thin content, Panda will slap you with a low score for short or unsubstantial articles. I will sell the product for 66$. If you are interested, please send me a private message.
