the world trade center was attacked on 11 th september 2001 and it is an important turning point in the growth of Google. few peoples are searched for details about the world trade center on Google but to their utter surprise no details was found. The news spread all over like as a fire and became another greatest drawbacks of Google. Google authorities are decide to take a decision to earn people’s trust.
Google processing are 3 ways
1) crawling
2) catching &
3) indexing.
PROCESS IN SEO
SEO consists of 3 main processes like: crawling, catching and indexing.
CRAWLING: Search Engines Spider/ Bot scans the documents in web pages, which is used for identifying the page by following the links on the pages.
CATCHING: After crawling, when the pages are “found”, it takes the snapshot of the website.
INDEXING: After catching, it is then stored into search engines database.
WEB CRAWLER/ SPIDER
It is a Google program which does this indexing process.
Web crawlers is a program for crawling web pages. It scans the web pages and tries to understand its contents. After the contents have been understood then takes a snapshot and saved it under the suitable category in its database. But in olden days, the website designers mainly focused on increasing the attractiveness of the webpages, which could not be crawled by Google contents.
EVOLUTION OF SEO
SEO became niche specific which is a content based technique for improving the ranking of websites. the particular keyword of the technique is present in a large quantity in the website to increase ranking. It is also called as keyword stuffing and it is a black hat SEO practice. Another similar technique is Meta stuffing. this technique Meta tags are filled with target keywords to increasing ranking. When Google realized it, google stopped ranking based on Meta tags in 2009.
Google brought about few changes in the matrix of its algorithm and change from niche specific to link specific. It includes no of websites with larger no of links will have higher rankings. Due to this reason companies began to sell links and web masters began to purchase from them, resulting in low quality websites.
Google then made an updation but this updation leads to a loss of a big revenue and this in turn affected their growth. So they were afraid to make updations.
Web Quality TeamAfter 2008, they created a special team to maintain quality called web quality team. The head of the team was Matt Cutts. In 2009, they build huge quality changes because they obtaines large companies like youtube, Gmail etc. This is updates were done to provide the users with high quality results. They try to transfer their search engine into something far better like a personal assistant. They added features like calculator, ip etc. they already try to make it more user friendly by adding a feature Google suggest so that people would like and depend on Google more. Google can also act as a personal search engine, in which Google stores details about previous searches and displays it to the users. This feature is not provide unless the users have logged in data center
on the basis of user interaction Google bring data centers for storing details about user interaction in 2009 . log in files of the browsers are collected by Google and then transfer to these data centers, which is in turn used by Google to rank websites. If the site is closed as soon as it is opened, Google realized the users do not like the site and Google decreases its rank.
Sticking Pogo
Moz.com is the world’s largest SEO community which introduced a concept called Pogo sticking. If a person searches for a diffrent keyword, then spends few time on one website and hits backspace and opens another website from the search list and spends a lot of time on this new website, the ranking of this website will increase and the other website will decrease.
Bounce rate
Next concept similar to Pogo sticking is Bounce rate. Bounce rate is a percentage of how many people spends lower time on the website without checking the content of the website. it can be used to determine the trust of the site. If the loading time increase then bounce rate also increases.
Exit Rate
next concept which is often confused with bounce rate is exit rate, it is a percentage of users who actively clicks away to other website after visiting the other pages of the website and it is the page on which the visitors have exited.
when social media was used increasingly Google made a change in the algorithm to include social media sharing to affect its ranking in 2010.This is known as social media signal. huge shares and likes will result in high ranking.
