What are google algorithms ?

Google Algorithms are the set of rules that retrieve data from the from its search index and also they give best possible result instantly for a query. 

Google algorithms understand what users are looking for and rank pages according to relevance and quality.

Types of google algorithms -:

• Panda algorithm

• Penguin

• Hummingbird

• Mobile Update

• Rank Brain Algorithm

• Bert

• Possum Update 

• Page layout algorithm

• Exact Match Domain 

• Payday Loan algorithm

• Hill-Top Algorithm

Let us discuss about this algorithms -:

Panda -:

It is one of Google’s official algorithm update. This update was done to reduce the low-quality data because in 2009 after the caffeine update the low-quality data also became part of the search results. To reduce that google make a new update and named its Panda.
Duplicate Content Plagiarized or thin content User generated spam Keyword Stuffing.

• Duplicate Content

• Plagiarized or thin content

• User generated spam 

• Keyword Stuffing

penguin -:

It was launched in 2012, the same as panda this algorithm also used to promote high-quality data in search results and also to not show the spammy content or low-quality data.

it was launched in 2012, the same as panda this algorithm also used to promote high-quality data in search results and also to not show the spammy content or low-quality data.
Spammy or irrelevant links. Links with over-optimized anchor text.

Hummingbird algorithm -:

This update was launched on 22 August 2013, its main work is to show the query that query on the internet which may not have the same word. It mainly focuses on the intention of the searcher. So hummingbird algorithm is important because sometimes grammatical mistakes occur during typing and results did not show up so this was corrected by using this algorithm. Keyword Stuffing Low-quality content

Mobile Update -:

As the name suggests this algorithm is for mobile search, its task is to show the Mobile-friendly pages on the top when searched from a mobile. This was launched on 21st April 2015 Today, Google ranks all websites based on how fast and user-friendly their mobile versions are. 

• Lack of a mobile version of the page 
• Poor mobile usability.

Rank Brain -:

It is a machine learning algorithm. It is kind of similar to a hummingbird, it's a machine learning from which Google understand and shows the best result. It is one of the important algorithms of Google and was launched on 26 October 2015. 

• Lack of query specific relevance
• Shallow content
• Poor UX

Bert -:

This Google algorithm update uses natural language processing technology to better understand search queries, interpret text, identify entities and relationships between entities. We’ve seen Panda, Hummingbird and Rank Brain updates move away from keywords, and the BERT update is the culmination of this effort — it allows Google to understand much more nuance in both queries and search results.

• Poorly Written Content
• Lack of focus
• Lack of Context 

Possum Update -:

This algorithm is mainly based on the location, it will show the local result according to the location. The nearer you are to the business address, the more chances that you will see it in your search result, and the result may vary on different locations for local addresses. This was launched on 1 September 2016. 

Page Layout Algorithms -:

This update was introduced by Google on 19 January 2012. After the release, this algorithm was updated on 9 October 2012 and the last update till now was on 1 November 2016. This algorithm is linked with the user experience. This algorithm affects those sites which have so many extra ads. So here in this algorithm, those sites in which ads force the user to see content, and approximately 1% of sites were affected.

• Algorithm Links with the user experience.
• Affects those sites which have so many extra  ads

Exact Match Domain -:

This algorithm was introduced in 2012. As the name suggests it works on the exact name and targets exactly what the name suggests. This update was to focus on the exact match of domain despite thin content and the quality of the site. The major weakness of EDM was that the websites SEOs would buy domains with exact match keyword phrases, build a site out, but have extremely thin content with little to no value on them. And it was so easy to do. The result of this update occurred in a way that, non-dot-com domains experienced a more severe punishment than .com counterparts. 

Payday Loan Algorithm -:

This algorithm was released in 2013, cause at that time the spam in Google was increasing. So to reduce Spam websites from Google search results this algorithm was introduced. This was one of the important updates by Google, which targeted Spam queries which were related to super high-interest loans and other heavily spammed queries.  

Hilltop Algorithm -:

The Hilltop algorithm is an algorithm used to find documents relevant to a particular keyword topic in news search. When you enter a query or keyword into the Google news search engine the Hilltop algorithm helps to find relevant keywords whose results are more informative about the query or keyword.
