Has any else noticed that the Penguin update is very inconsistent? I've seen websites for keywords, that have link profiles that are full of blog/forum comment links, and also 100's of exact anchor text matches. To the point where if you were to analyse a site, their backlinks, their on page and try and follow a similar strategy, you are in theory doing exactly what Penguin is clamping down on? Any thoughts on this? Im basing this on what I have read around this forum with regards to where Penguin has apparently hit sites the hardest.
