Google “Panda” Algorithm Update

Google’s recent algorithm update aimed at improving the quality of search results has captured a great deal of attention – both positive and negative. The general consensus seems to be that the results are in fact better now, but still not perfect. Perfection will likely never be achieved, but there are still some glaring criticisms out there about Google’s most recent attempt.


Having had some time to reflect, what is your opinion of the update? Let us know in the comments.

Despite the improvement in overall search quality in general, there have been many sites to suffer the consequences of the update – some deservedly and others maybe not so much. As Google will never reveal its secret recipe in its entirety, there are plenty of clues out there, and even facts that Google will share. You can criticize Google’s mystique all you want, but there’s not denying that they do communicate with the webmaster community to a great extent, even if they don’t always tell you everything you want to hear.

Google’s Matt Cutts and Amit Singhal – two of the most instrumental voices in the recent update – shared some clues and insights in an interview with Wired this week. Before we get to specifics, there were some interesting things mentioned by the two that are worth noting. For example, Caffeine, which sped Google’s indexing, led to a flood of content – both good and bad. This seems to have helped the “shallow” kinds of content that this most recent update targeted – not stuff that is quite spam, but…well, shallow. We also learned that Google calls the update “Panda”.

They revealed that prior to the update, they sent out documents to outside testers/raters, and asked them questions about quality. It would be interesting to know who these raters were, but no such luck there. Users were asked things like whether they would feel comfortable giving a site their credit card info or giving medicine from the site to their kids (I wonder if anyone was asked if they felt comfortable getting their brain cancer information from a freelance eHow writer with no credentials in the field), whether they considered the site to be authoritative, whether it would be ok in a magazine, whether it has “excessive” ads, and other questions. It would be great to be able to know more of those questions, but we can only work with what Google has revealed.

“And based on that, we basically formed some definition of what could be considered low quality,” Singhal is quoted as saying.

“We actually came up with a classifier to say, okay, IRS or Wikipedia or New York Times is over on this side, and the low-quality sites are over on this side,” said Cutts. “And you can really see mathematical reasons…”

“I got an e-mail from someone who wrote out of the blue and said, ‘Hey, a couple months ago, I was worried that my daughter had pediatric multiple sclerosis, and the content farms were ranking above government sites,’” Cutts is later quoted as saying. “Now, she said, the government sites are ranking higher. So I just wanted to write and say thank you.’”

Again, why is eHow still ranking for “level 4 brain cancer”?

Google says it still looks at feedback, and Cutts even said that if someone has a specific question about why a site dropped, he thinks it’s “fair and justifiable and defensible to tell them why that site dropped.” He also said that Google’s most recent algorithm contains signals that can be gamed (hence the lack of full transperency). In other words, it can still be optimized for.

Finally, the site Suite101, which data from SearchMetrics lists as the biggest loser in percentage (in its organic performance index) was brought up in the interview. Suite101 and eHow are often compared and labeled as “content farm” type sites. When asked why Suite101 took a much bigger hit than eHow, Cutts simply said, “I feel pretty confident about the algorithm on Suite 101.”

It would be very helpful to understand the differences Google sees between these two sites. It doesn’t seem very clear by looking through the sites that there are obvious differences in quality. I’m sure it varies on both.

We reached out to Suite101 a few days ago for comment on the update and its impact, but have yet to receive a response. I’m even more interested to hear what they have to say, now that these comments have come out. Update: Suite101 referred us to an open letter from CEO Peter Berger to Google’s Matt Cutts.

CEO Peter Berger stressed the importance of quality in content when we spoke with him last year.

“Every week, several thousand people apply to become Suite101 writers,” he told us. “While we only accept a portion of applicants based on our non-negotiable quality standards, we do have many successful writers on our site who do not consider themselves ‘writers’.”

“We see it as Suite101′s mission to enable people – anyone who can write well and with deep understanding of a subject – to achieve their goals,” he said. “These might be earning money, addressing large audiences, building up a personal professional brand, or simply enjoying creative freedom in a nurturing, peer-oriented environment.”

Results from people with a deep understanding of a subject should lend themselves to quality. Whether or not Suite101 delivers on this is open for debate. Clearly Google doesn’t think so, practically making the site the poster-child of what not to do. The mysteries continue…
