Predictive 404 is another WordPress plugin inspired by Russ Jones’ post on SEOMoz, that assists in PageRank recovery by:
* Capturing the URL that the visitor or GoogleBot tried to visit.
* Using Levenshtein Distance to figure out the intended URL.
* 301 redirecting to there
For example, browsing to http://gunnertech.com/internet-markteing will automagically redirect to http://gunnertech.com/internet-marketing
