Does anyone have a site that has less than 50% keyword anchor text that was still hit by Penguin? I'm sure most of you have seen this article floating around http://www.micrositemasters.com/blog/penguin-analysis-seo-isnt-dead-but-you-need-to-act-smarter-and-5-easy-ways-to-do-so/ They drew a few conclusions based apparently on a large data set. Something sticks out to me when I look at that article: 1) Not every site that had a high % of anchor text backlinks what hit (I know this already from some of my sites, but it makes point number 2 very interesting) 2) Apparently out of all the sites they track NONE of them that had <50% of their backlinks with keyword anchor text were hit by Penguin. If that is true, then having a high % doesn't necessarily mean you will be hit, but having a low percent would (according to their data) guarantee you will not be effected by Penguin. Based on the wording of their article, I'm guessing that they count various longtails and keyword variations within that percentage and are only counting things like raw URL, brand, click here, etc as non-keyword anchor texts. I generally don't do a ton of backlinking to my sites with "click here" though I do some brand and raw URL it's not in THAT quantity in general. IF their data is correct, it would lead me to believe that there are other factors in play with penguin but the main trigger is a lack of non-keyword anchor texts. If the algorithm deems you lacking in variety there, then the other factors come into play and you may or may not be hit. If the algorithm thinks you have enough non-keyword anchor backlinks then the other factors never even come into play. Again, this is just a logical examination of the data presented in that article. I don't have enough of a sample size myself of sites that were hit by Penguin to make a judgment call on this. I'm wondering though if anyone here has a site that contradicts this(it is a whole lot easier to disprove a theory than to look at all the examples that confirm it)? i.e. a site that has at least 50% of its anchor texts consisting of raw urls, "click here", "this site", brand name, etc and yet that site was still significantly dropped by the Penguin update?
