As predicted, Google has eventually launched its big list of algorithm changes for the month of April. It’s recently been an interesting month, as you would expect, without only the Penguin update, but a few Panda updates sprinkled in. There’s not really a whole lot about either of the people on this list, however, that is a real proof of exactly how many things Google is constantly doing to alter its algorithm – signals (some of them, at the least) which may help or hurt a person in different ways aside from the hugely publicized up-dates.
We’ll definitely be searching a little more into a few of these in future articles. In a quick glance, I noticed some more freshness-related tweaks. Google has additionally broadened its index base by 15%, that is interesting. As far as Penguin goes, Google does talk about: “Keyword stuffing classifier improvement. [project codename "Spam"] We have classifiers designed to detect when a website is keyword stuffing. This change made the keyword stuffing classifier better.”
Keyword stuffing is in opposition to Google’s quality guidelines, and also was among the specific things Matt Cutts pointed out as part of his announcement of the update.
Interestingly, in contrast to previous lists, there isn’t any mention of Panda in any way on this list, though there have been 2 known Panda data refreshes during April.
