What are Google Algorithms?

With the growing popularity of Internet Marketing, Google Algorithm is the term we all have heard about. But before talking about Google Algorithm, let’s talk in general what algorithm is. An algorithm is a set of rules for solving a problem in a defined number of steps.

Google Algorithms follow the same rules but frequently change with time. Google has an immensely complex algorithm for searching. Though they have not made their exact algorithm public, we still tried to figure out a few elements which may have an impact on the search results. They are:

• The appearance of keywords in page content, meta description tags, and header tags
• Organic backlinks to your site
• Website performance on mobile devices
• Website ranking in SERP

Google Algorithm process for Search

Google’s algorithms have developed dramatically in the past few years, and now they rely on more than 200 unique signals that enable the users to find what they are looking for on the web. The process starts with crawling and indexing the web pages for which Google, as well as other search engines, have their own robots, crawlers or spiders, known as ‘Googlebot’. These robots move from one page to another to analyze the content and crawling.

Google Algorithm Major Updates

Let’s have a look at the most significant Google Algorithm updates of all the times:

1. Google Panda: Launch Date: 24^th February 2011

Google Panda is one of the major updates as it evaluates websites based on content quality. High-quality content pages are rewarded with higher ranking positions and vice versa.

This update is primarily to maintain good quality content. A ‘quality score’ has been assigned to each web page, which is used as a ranking factor to rank for sites in SERP.

To overcome Panda’s effect, webmasters should keep an eye on duplicate or thin content of their website.

2. Google Penguin: Launch Date: 24^th April 2012

Google Penguin targeted websites with bad or spammy links. The primary objective of this update is to decrease rankings for websites with webspam or those violating Google’s quality guidelines.

To overcome Penguin’s effect, do a regular backlink audit of your website and remove spammy or irrelevant links.

3. Google Hummingbird: Launch Date: 22^nd August 2013

Hummingbird is considered one of the most significant changes in Google’s Algorithm history. This Algorithm pays attention to each word user is asking as a query and gives you the best result. Its primary objective is to make interactions more human by making search results more relevant.

To overcome its effects, webmasters should expand their keyword research and focus more on concepts and not keywords.

4. Google Pigeon: Launch Date: 24^th July 2014

Pigeon affects those websites with on and off page SEO. Users started focussing on their Local search results and start investing in off-page SEO.
