Understanding SEO in the Context of Recent Google Algorithm Changes
Google has always been making changes in its search algorithm. These changes are so frequent that it is difficult to keep a track of all of them. In fact, it is said that Google makes around 500-600 changes in its search algorithms every year.
The many search algorithms that Google makes use of are: Google Hummingbird Update, Google Penguin Update, Google Panda Update, Google Pigeon Update, Google Mobile-Friendly Update, Google Payday Update, Google Pirate Update, Google EDM Update, Google Top Heavy Update and Google Page Rank Update. In order to understand your domain authority on the search engine results page, you need to first understand what these types of search algorithms mean and how they affect the SEO in light of the changes incorporated in them recently.
The Hummingbird Update focused more on the meaning of keywords and phrases rather than exactly matching these keywords or phrases. It laid great emphasis on mobile marketing. The recent changes that Google Hummingbird has incorporated, relate to the usage of Knowledge Graph facts to enhance the search results and also applying the meaning technology to millions and millions of websites from across the globe.
The Hummingbird update did not bring much difference to the SEO. Google now started showing up more relevant pages than before since the meaning of the keywords was now considered.
The Penguin Update, on the other hand, had a basic task of catching those websites that do not comply with the norms of the Google Webmaster Guidelines and try to improve the rankings of their websites by adopting wrong means. This was done to penalize the websites that were adopting such wrong means. Google wanted to send through this search algorithm, the message that those websites with good content will be recognized and a penalty would be given to those that use content that was spam. “Penguin now devalues spam by adjusting ranking based on spam signals, rather than affecting the ranking of the whole site”, says Gary Ilyes, the Google Webmaster Trends Analyst.
The Panda Update was designed to search for all the spam websites on its search pages. This was done to ensure that the users of the website could get more unique results for their searches. This was a major attempt made to penalize those blogs that had copied content from various other sources.
Google Pigeon focused on getting more local content on the search pages. The changes made in this are also reflected on Google Maps. This algorithm was designed to improve the distance and location ranking parameters. It is not a penalty based algorithm. In fact, the local businesses have found an increase or decrease in their referrals after the introduction of this algorithm. This is extremely beneficial to promote local businesses.
Google Mobile-Friendly algorithm basically focuses on using a Mobile-Friendly Test Tool and ranks your websites on the basis of the scores that taken out by that tool.
Google Pirate Update keeps an account of all those websites that have multiple infringement issues regarding copyrights. These results are generated through the DMCA system of Google. It is continuously updated so that the websites that have made corrections are not affected anymore.
Google EDM: EDM, as we all know, stands for Exact Match Domain. This algorithm was launched to keep a track of those websites that are low in content but manage a good rank on the search page due to a match in their keywords. This algorithm makes sure that all those websites with good quality content are not missed by Google if they have keywords similar to websites with poor content.
Google Top Heavy: This algorithm was developed to capture all those websites that were heavily loaded with advertisements. It prevents the websites with high advertisement content in them from getting high ranks in the search results. It also keeps a check on the websites that have updated themselves and removed some ads so that they can get better ranks on the search page.
Google Payday: This update was developed to keep a check on websites that were using various techniques of search engine spamming to improve their rankings on queries related to various spam content.
All the above-mentioned algorithms given by Google have been updated time and again to ensure that the page rankings keep getting revised and not a single page can have a similar ranking every time.
