GOOGLE HISTORY Google began in March 1996 as a

research project by Larry Page and Sergey Brin, Ph.D. students at Stanford University.

It was first named as ‘backrub’ because the system checked backlinks to estimate the importance of a site.

They changed the name to Google, originating from a misspelling of the word "googol”.

Google's original homepage had a simple design.

Why google started with algorithm updations?

Initially very little was needed to fully optimize on page content.

The inverse relationship between query position and weight, simply put one’s important keywords higher on the HTML tag hierarchy.

This was relatively simple algorithm. So webmasters quickly discovered tricks

to vastly boost their SERP .

Page 5: Google algorithm updates

They started practicing link keyword stuffing on page content.

As a result, google removed these sites from its index.

They started to practice this to punish disingenuous webmasters looking to cheat the system.

Each year Google changes its search algorithm hundreds of times.

Google Algorithm Updates have high impact on SEO. As it effects the search result rankings.

from working their way into Google’s top search results.

useful) Poorly written content Content copied from other sites Content that’s not useful

Panda is updated from time-to-time. When this happens, sites previously hit

may escape, if they’ve made the right changes.

Panda may also catch sites that escaped before.

Latest Panda Updation was Panda 4.2, July 18, 2015.

It was the 30th updation of Panda. In which 2–3% of queries were affected

Google Hummingbird

Hummingbird is the name of the new search platform that Google is using as of September 2013.

Its meaning is “precise and fast” and is designed to better focus on the meaning behind the words.

Hummingbird is paying more attention to each word in a query, ensuring the whole query — the whole sentence or conversation or meaning — is taken into account, rather than particular words.

Page 16: Google algorithm updates

Google Hummingbird is designed to apply the meaning technology to billions of pages from across the web, in addition to Knowledge Graph facts, which may bring back better results.

Rank Brain

Rank Brain is an artificial intelligence (AI) program used to help process Google search queries.

RankBrain uses artificial intelligence to embed vast amounts of written language into mathematical entities, called vectors,  that the computer can understand.

Page 18: Google algorithm updates

If RankBrain sees a word or phrase it isn’t familiar with, the machine can make a guess as to what words or phrases might have a similar meaning and filter the result

According to Google it’s the third most important factor in determining the results that appear in your search queries.

Google Payday loan

Google launched the Google Payday Loan algorithm to filter out lower quality websites.

They were using a variety of spam techniques to boost their rankings for heavily trafficked search key word queries.

Google Mobile-Friendly update On April 21 2015,

Google released a significant new mobile-friendly ranking algorithm that’s designed to give a boost to mobile-friendly pages in Google’s mobile search results.

In order for a site to be considered mobile-friendly,

* Its text has to be readable without tapping and zooming.

* tap targets need to be spaced out appropriately.

* The page avoids unplayable content or horizontal scrolling.

As more than 60% of the search is from mobile devices, it is important that the site needs to be easily usable from a mobile device.
