Chatter levels are increasing on forums like Webmaster World about yet another Panda update going on now. Right now. For those who like tracking by numerical sequences, this iteration would be panda 2.4.
According to Rand Fishkin at SEOMoz, what makes Panda revolutionary is that it is a learning machine. Perhaps considered by some to be not too unlike the Terminator, always gathering information about and better understanding human behavior. In terms of artificial intelligence, Panda’s view of the world was formed in a soup of months of study and opinion gathering from web activities of real human beings. Google has confirmed that extensive research was performed where people were presented with websites and were simply allowed to vote whether they like the website or they didn’t like the website. This could obviously include factors ranging from colors and appearance to images, animations and graphics to menu systems and of course, the text content and layout of a website.
Panda has since recursively crawled, not the web, but the Google index and evaluated the websites in the index and rearranged the search results based on its learning of what is in the index compared to its core learning algorithm from the research accumulated and somehow translated into the “Panda Intelligence”.
These recursive reviews of the index and subsequent rearrangement of the SERP (search engine results placement) seem to indicate that Panda comes back around each time, apparently about once per month, with a higher level of intelligence and understanding of the web. Whether or not this is the real-time result, it is certainly the theory and it is a theory that Google is so far sticking with.
I have a pretty strong notion that if I am reading content and feel like I’m being gamed with duplicate or rehashed content–and I don’t like that, Panda it is probably going to sense the same thing sooner or later and filter out the same things that I don’t like from search results. That is clearly Google’s intent and if you happen lately to type in a misspelled or incorrect word into Google search you’ll notice that Google has a pretty good idea what you are actually searching for and gives you results for that term first.
