Search for Interflora (a popular flower website in the United Kingdom), and you will find that their website no longer exists in the search results. Not only this, they no longer exist in the ratings for their keywords, such as ‘flower delivery’ and ‘flower’.
It looks like a penalty, because of the fact that in the past websites have lost ratings only because of being penalized by Google for buying links or any other reason for that matter.
When asked about the same from Google’s representative gave the reply –
‘We typically don’t comment on whether we’ve taken corrective web spam action regarding specific companies’
As far as Interflora is concerned, there has not been any official statement from their side. So, there is no confirmation about the real reason for this loss in site rankings.
