Each of these Google algorithms pays attention to specific factors in the sites and ranks the sites based on them, the Google search engine never determines exactly what factors are important for each of the algorithms in Google and you can only make guesses by paying attention to the changes that have been made on the results page.One of the same Google algorithms that was added to the others, which caused a lot of changes in local search results, is Google Possum, which we will learn more about in this article, but first we need to be familiar with the Google algorithm itself.
What is Google Algorithm?
Google algorithms are computer programs that have mathematical functions and formulas and analyze and classify the contents of sites with the help of Google crawlers, Google's goal is to deliver the most appropriate result to the user and provide a positive experience to the user in using the search engine.There are different types of algorithms, among which are Mobile friendly, Page layout, BERT , Your Money or Your Life, EAT, RankBrain and Possum, each of these algorithms pays attention to different factors for ranking sites , and ultimately sites that are more user-friendly and provides user with the answer of their questions faster will be at the top of the search results page.
What is Google Possum Algorithm?
Google Possum Algorithm , is an algorithm that was updated in 2016, and it is an update to rank sites in local search, and as we mentioned, it made changes in local search results, one of these changes was that through this algorithm a number of businesses with the same address, were filtered and not shown in local search results, and also led to other changes, all of which resulted in more satisfaction for users who choose the Google search engine to get the answers of their questions.
What local businesses does Google Possum Algorithm affect?
Various businesses were affected by the introduction of this algorithm, which we will mention.
1. Businesses that had the same location:
Before the introduction of the Google Possum Algorithm , businesses with the same address were displayed in a way that prevented duplicate content from being generated, for example, imagine that a large number of ophthalmologists were located in one building, at this time, as a result only a small number of them were displayed on the search results page, and the rest of them were not displayed because Google was receiving signals that they were duplicates.After the Possum update, similar jobs listed with the same address were being filtered, and for example, and only one or two of them were displayed, this filter can be eliminated and all these results can be shown, but it is not possible for every user because they are not aware of this possibility, so ultimately this algorithm has had a negative impact on many businesses.
