It looks like the infamous Panda Google update has arrived outside of the USA. According to Google the Panda update (some times called Farmer/Panda) is meant to better identify low-quality pages and sites.
These are the sort of pages (often seen on “content farms”) with text that is automatically tuned to match the query – but may not provide the best user experience. (Google apparently calls it a “high quality sites algorithm.)
I am due to help give a presentation on SEO to a group of RBI’s developers on Wednesday – so guess whos going to be quickly revamping the presentation deck tomorrow – as well as groveling in the Analytics data to see if any of our sites have been hit.
