Whereas it is easy to see how Google can conclude a sights content has been copied from elsewhere in its Panda updateit is hard to see how it can judge whether content is useful when the algorithm only sees words and cannot be expected to make sense of sentences.
However as well as hitting the intended internet spammers the massive update also hit a lot of innocent bystanders who have quality websites.
So what can you do if you feel you were innocently caught out in the spam fight crossfire? Well searchengineland confirm that it is not worth appealing to public opinion because Google has categorically stated this is an algorithmic change and not manual review. There is no white list or blacklist of favoured sites like in the case of Blekko so there is no need of feeling personally aggrieved.
Google admits mistakes can be made with any such change since no algorithm can produce 100% perfect results.However Google is keen to learn of any casulties in a quest to perfect the algorithm so so it has put a thread in their forum for those who feel they were unfairly affected. So if you – think you’re affected by the recent algorithm change? Post here.
