Over the past four days or so I have been noticing a lot of spammy traffic coming from strange websites. My domain is http://mattwarrell.com and when I go to investigate these pages, my link doesn't appear on them or 404s.
They all seem to have similar themes within well-known websites - like 'home loans' on MSN.com or WordPress.org or foxnews.com or CNN etc. But obviously these all bring up 404s. For example - http://apple.com/advantagerentacar
The other day I had 491 hits but I counted only around 60 of these were from sources that made sense and have backlinks on.
I'm worried whatever or whoever is doing this is going to get my website penalised by Google. Anyone have any advice on this?
