Bing and Google Page Rankings
A search engine has specific criteria to determine which webpages will be displayed first in a typical web search. While the exact criteria that determine page rank are generally not released to the public, the general ways that page rank is determined are available. In the case of the search engines Google and Bing, there are some distinct differences with what pages are displayed.
Ignite Visibility, a digital marketing company out of San Diego discusses some of the differences of optimization in the Google and Bing search engines. First, Bing seems to focus more on local businesses than Google does. Second, Bing also focuses more on page authority than Google does. In fact, Bing will get not display webpages if they don’t have enough page authority. Lastly, Bing integrates social media relevance into their rankings. If a website has a high number of likes, retweets, etc., then it will likely have a higher ranking.
With this information, we can also implement a situation of game theory into how a user and a website owner may make decisions in order to best suit their needs. For example, a random person is looking to find a new restaurant to try out. The website owner (small, new restaurant owner) will want to attract that customer into their establishment and wants to optimize their website for a specific search engine. If the random person is wanting to find new restaurants in their area, they will use the dominant strategy of using Bing to find a lesser-known restaurant as prior testing has indicated that Bing is more advantageous to find local businesses than with Google. Likewise, the dominant strategy for the restaurant owner will be to focus on optimizing with Bing as it will probably have a higher page ranking than with Google.
Note: The example assumes that a user would use the best browser to find the information they are looking for.
