Google’s Matt Cutts Explains Fluctuating Page Rank

Results Change Over Time as Algorithms Determine Relevance

Google’s fluctuating page rank can be confusing.

Your new site or page might rank well initially but, after a week, it begins to drop, declining over time to a middle-of-the-pack slot. Why?

Matt Cutts, head of Google’s Webspam team, recently put together a video to explain the phenomenon.

Cutts said Google’s algorithms can, initially, have a hard time figuring out the original source of new content. Time changes that, however.

“Writing a search engine is kind of a complex task,” Cutts said. “You’re trying to make sure you return the best quality result but you also have to do that with limited information.”

Cutts likened the ranking process to the reporting of breaking news during an earthquake.

For instance, he said, one minute after an earthquake occurs there is limited information about what happened, ten minutes later there is slightly more information and an hour later a lot more information.

“With any event that has breaking news, it can be hard to know (what is accurate) even if multiple people are saying the same thing,” he said. “One person might be the original author another person might be using an RSS” feed to relay information.

“It can be difficult to try to suss out … where this content was appearing originally. And, over time, over the course of hours, days or weeks, that gets easier. But it can be hard after just minutes or hours.”

Cutts said initial rankings are often Google’s “best guess” on how relevant a page or piece of content is.

As more information becomes available, Google incorporates its new knowledge into the mix and, “typically, things settle down into a steady state,” Cutts said. “When there is a steady state, we’re better able to guess how relevant something is.”

Armed with that information, Google can then determine if the page or content would be better served by QDF (queries that deserve freshness) or evergreen.

QDF is a component of the Google algorithm for queries that need frequent updating, such as breaking news stories.

If Google determines the best results for a particular search will change daily, or even hourly, it will designate the search QDF. Such designations means new and relevant content will make its way to the top of the search results. It also means, however, that content will quickly be bumped as newer relevant content is posted.

Evergreen, on the other hand, is a term Google applies to pages or sites that are frequently updated and are likely to attract both first-time and repeat visitors.

“A lot of people think there should be one set of rankings, it should be completely uniform, everybody in the world should see the exact same thing,” Cutts said. “The fact is, we have different results for people in different countries, even in different cities.

“And the results can change over time. Not just because links change or the content on the page changes, but because we are better able to assess which pages are more relevant.”

    I noticed a better ranking after getting several new links pointing to a domain name and after a few days the results drop again. Is that for the same reason described above?

    I saw this video last week, not that it was any news. It has been easy to see how the way Google tries to use fresh content in results for a while and how rankings can fluctuate in the first stages of a page going live.

    Few a days ago, one of my site’s internal page rank went down from 3 to 0, while the home page page rank did not affected, but still the internal page rank is 2 but I couldn’t understand the reason.

    How do “reference” sites fit into this scheme? Medical content, for example, is updated only occasionally.

    Hi Lenore,
    I am not certain how reference sites would be ranked. It could be that they would be termed as ‘brown’ which is for websites that are not updated frequently. Unfortunately, Matt didn’t explain how sites that don’t fall into QDF or evergreen are affected.

    Thanks for this article Jennifer. It gives a very useful insight into the google algorithm.

    Thanks for the feedback Michelle.

    It’s a good possibility Angy.

    Help! My PageRank didn’t just fall to zero – it apparently no longer exists! Can you stop by, take a look, and help me out?

    Hi Dave,
    Unfortunately I wouldn’t be able to help — I’m far from being an expert. I’m just a journalist.

    A little difference in search rankings is understandable. However, for one of the keywords that I am targeting, we are ranked at #11 when searching from India, 100+ in the US, and around 75 in UK. The term is relevant to all three countries though so the ranking should not be so different… 🙁

    The earthquake idea, and how the information of an event may be assessed differently after an hour, day, week or months is an excellent way to illustrate ranking variations. The idea of an evergreen site is also worth knowing. However every one knows an evergreen site that never changes, and has used black hat manipulation to achieve top position, but Google just doesn’t see it.
    That’s frustrating!

    Yes, sir you are saying write it will take time must syndicate unique content.Thanks sir.
