Google and Pagerank
We learned in class the importance of pagerank and how Google utilizes this algorithm to make its search engine the best in the world. But from the producer point of view, meaning the people who manage the websites which pop up in the Google searches, they think of the same algorithm when designing their sites. But recently Google is attempting to give credit to the companies who give actual information on their sites and not simply win the system. This is by fact checking and not deciding just on buzzwords or the number of outbound links. So from the point of view of hubpages and authority pages, the next system by Google will filter out the potential spam links which exploit this idea. And this in turn might decrease the levels for hub pages. But this is also a problem because it is rather difficult to detect such accuracies and it might cause the search engine to actually perform worse than what it was doing before.
Changing the current system is unstable from the point of view of Google but will allow users to get more accurate results than before. Initially even it was not completely successful and resulted in lower turnouts but as time progressed, they had to practice filtering the correct and most accurate results to make it to the top. This slightly improved the user experience and gave more precise results.
There was also slight ambiguity initially as to what is most accurate and necessary to be on the top. But a large and experienced company like Google was able to quickly adapt and put the user experience on the top rather than just simply what is easiest. And they were able to link to the sites which might not have been the most spam ridden with links and ads but instead had the content that users were looking for, thus accomplishing the main goal. This was just one method that the tech giant used in the ever changing markets and in the future there might be additional ones it uses.
