As we have read in the topic How Google works there was a term algorithms which decide the relevancy criteria of a website. In simple terms you can say these are the rules and regulations which a website must follow in order to rank higher.
Note: Google used to update its algorithm very frequently so you must follow Google News to be up to date with these algorithms.
In this section we will read the different algorithms on which Google works through which it decides the ranking criteria for your website:
A. Google Panda Algorithm:
Initial Release Date: February, 23rd 2011
Description: Now let’s read the different factors which it covers and you must consider for your website content:
- Thin Content: The content of your website must be relevant and should provide in-depth analysis of the topic which you are covering.
- Duplicate Content: The content that you upload on the website must be original (Plagiarism check must be performed). The content within the website must not resemble each other. For example a website that sells its similar product in different parts of country and have different web pages with same for each city will be considered as duplicate content.
- Lack of authority/trustworthiness: Your website must be secured and should not be affected by any type of malware attack
- High ad-to-content ration: Try not to increase the ads ration of your website more than its content. It will eventually lower your website rank.
B. Google Penguin Algorithm:
Initial Release date: April, 24th 2012
Description: These are the two factors it covers:
- Link Schemes: The entire website which contains spam links, paid backlinks from unrelated high rank website were rank out from Google search engine result page after the launch of Penguin Algorithm.
So, in order to make your website Penguin friendly you must remove all the spam links and paid backlinks related to your website.
2. Keyword Stuffing: Under this you cannot over optimize your website on the basis of keywords because it will lead to keyword stuffing. You must maintain a good ratio between your content and keyword.
C. Google Humming Bird Algorithm:
Approx. Release Date: August, 20th 2013
Description: The important factors that it covers (this update doesn’t affect the ranking of webpages):
- Knowledge Graph: Let’s take an example to understand the concept behind knowledge graph. I type a search query How to make chocolate cake and Google show me below knowledge graph:
2. Concept of Semantic Search: In addition to knowledge graphy Google also introduce semantic search which was a concept based search where Google start predicting what we are going to search. See below example:
D. Google Pigeon:
Initial Release Date: August 20, 2013
Description: The advantage that user gets after the Pigeon roll out was that the local searches get improved. Because after the pigeon update Google start showing the results more focused towards distance and location.
Likewise after every updates from Google there is some change in the ranking of websites. Let’s take a look what changes does this update brings:
- The prime focus of Pigeon update is to promote the local business to get online and list them up in order to help Google to showing them to the user who is searching for them. In this way Google start showing the results based on the distance and location of the searcher.
E. Mobile search result algorithm:
Initial Release Date: April 21, 2015
Description: Google start ranking those websites higher who is not only desktop friendly but also are mobile friendly. The reason behind bringing this update might be that Google recognize that the majority of searches are being done on mobile devices. So, Google make it mandatory for the websites owner to make their website both desktop and mobile friendly.
By mobile friendly I mean all the function of that website should work on mobile, resolution should be perfect, loading speed should be same and other important factors should be considered to make it more users friendly.
F. Google Rank Brain Algorithm:
Initial Release date: October 26th, 2015
- This update brings Google’s machine learning into plat while showing the result on Search Engine Result Page (SERP).
- Basic idea behind this update is to make the search results more focused towards what user want. The same it achieve by decoding users intent, data input, location etc. in order to provide best matched result.
- Let’s take an example to better understand this update. For example user search for Cricket Word Cup now Google applies its Rank brain algorithm in order to recognize users intent weather the user looking for cricket world that will be played in 2019 or seeking information related to 2015 world cup. Here if Google runs on simple algorithm will show the result based on the website content where the words have been seen more times, the number hits a specific website have get for it and will display the result but with this update Google will be decoding users intent by taking into consider its location, the way he enters the query, possible intent and other factors before showing the most accurate result.
G. Google Possum Algorithm Update:
Initial Release Date: September 1st 2016
Description: Basically this update affects the local business listing. The result as organic search listing will remain the same however your search results of Google Map listing will fluctuate.
Now let’s analyze it impact on SEO industry:
- Local Listing get affected:
Let’s take an example I search for chicken restaurant nearby me and there might be a chance that there are so many restaurants near me. Initially what happens that Google use to provide you a huge list of 7 or more restaurants in its business listing results page but the same is not true after possum update. Now the local listing result have been shortened and contain some good reviewed listing on the search result page (2 -3 listing only) rest other can be browse after clicking on “more places” option.
B. Business outside the city limit gets a boost:
This point is little tricky let’s take an example to understand it in an easier way.
For example I want to search for plumbing in New Delhi when I hit this search Google is going to boost the results which are at the border or city limits of New Delhi and serving your area.
Confused? Let me explain this example a little bit in details.
What actually may had happened is that the owner might work from home and during Google Map listing he had listed his home address there but when it comes to servicing area he might had mentioned your area so Google boost its search result based on the reviews, rating and other important factors.
C. Filtering by Address:
For all those businesses who have listed those on Google twice or thrice for the same services with the same owner name just get a boost they are outranked by Google.
For example you own a Law Firm and for each service you have multiple attorneys and you list them all separately though they have same services to offer. Now Google have become strict and will out rank you if you follow this technique. Add your services there and associated attorneys should be there in the description rather than creating separate listing for all the attorneys.
D. Adapting to the unique needs of users:
This one is important and most of us follow it as well. This simple means that you must have all the keywords in your listing that user generally types in their search query when they are looking for you.
H. Google Fred Algorithm:
Initial Release Date: March 8th, 2017
Description: It was more based on quality of your website. The website that you owned must follow all the Webmaster guidelines and should not run to earn money via affiliate marketing or Ads instead of maintaining good quality content within search engine guidelines.
Some of the important aspect that Google search for:
- The website owner must give its proper information
- The page description must contain quality content
- The page must be error free, loads quick and must have few technical errors
- The website reputation must be good it contains quality backlinks, review, rating etc.
Other Algorithm that may be of your interest:

- Google Page Layout Algorithm: it was released in January, 2012. The purposed of this algorithm was to downgrade the website which is based on advertisement rather than content. They provide a long set of ads on the top page rather than quality content
- Google Payday Loans Algorithm: It was released around June, 2013. The major focus of this algorithm was to downgrade website promoting spam links on highly competitive keywords. These links generally redirect the user to a malware attack which may even hack their device.
