We all know google is the top search engine in the world. ( Thanks to Larry Page & Sergey Brin )
Google always have answers about whatever we asks. Today we can't imagine a life without these kinds of search engines. From simple to complex things we all depend on search engines like google. But can you imagine there was a time when google itself felt that its really falling down to a non trustworthy search engine?? Yes they do!
The three basic functions of google is crawl, index and caching. But in old times websites are not crawlable because at that time they have no idea in marketing. They only try to make website more colorful and attractive by adding bigger size images and flashes. Due to this google takes more time to crawl and failed to give results. So the officials in google gathered and discussed about these issues. At this discussion they found a solution and it is search engine optimization (SEO). But some officials opposed because they thought if they share the optimization tips it will affect google's existence. After many debates and discussions finally they decided to share the optimization tips to webmasters.
Google shared starter guide to webmasters but it wasn't a happy ending. After getting the optimization tips they misused it. Webmasters maintained technical side only, to place their website in top rank. They never tried to provide quality content. In early times google give importance to content specification. After noticing the misuses google updated its algorithm. Google came up with following features in the past years, they are link specific, quality link specific with page rank, passing the juice. Passing the juice huh?! Sounds funny, right?! Lets check it. We can simply say if the page ranked website provide unusual links to other websites then that page ranked website's rank will automatically fall down. This value is passed through hyperlinks. With this they also introduced rel=nofollow, it is a value that tells the search engine that the hyperlinks should not influence the ranking of the website.
From 2009 onward google introduced new features for visitors and they are google suggestions, personalized search results etc. After years of struggle to gain users trust google decide to show results depending of website's rank. Depending on users interaction a websites's rank can be increased or decreased. If the visitor close the website within seconds then the rank of the website fall down, it is called Bounce rate.
From 2010 onward social media became a big hit so google included social media as a part of them, that is if the website shared via social media then its rank increases. To make it more efficient and trustful they introduced social media authority value. In 2011 google became stronger and done strong updations. They introduced new updations to stop misuses and they are Panda updation to find content spamming, Penguin updation for link spamming, Parked domain updation, Exact match domain updation, Humming bird updation to give semantic search result, Mobilegeddon updation to make website mobile friendly and pigeon updation.Panda Updation
Panda updation is to avoid content spamming.
⇨ Content plagiarism
⇨ Content spinning
⇨ Thinny pages
⇨ Keyword stuffing
The first updation was in 2011 and after that many updations done. The panda updation became big hit. In May 2014 google done panda 4.0 update and millions of content duplication pages removed. They added panda updation in main algorithm as a permanent filter. Because due to this updation google can provide quality contents in search results.
penguin Updation
Penguin updation is to find link spamming.It includes:
⇨ Link exchange
⇨ Link selling or buying
⇨ Link farming
⇨ Comment spamming
⇨ Wiki spamming
⇨ Over guest blogging
The first penguin updation was in 2012. In 2016 google done penguin 4.0 updation. They changed link spamming into real time.
Humming bird Updation
Mobilegeddon Updation
Mobilegeddon update is to make websites mobile friendly. That is, the website's text will be readable without tapping or zooming. In this case horizontal scrolling not possible, only vertical scrolling. The first updation was in 21st April 2015. Google done the second updation in 12th May 2016 and it is a strong update. After this if a website is not mobile friendly then in search result google show a text that tells the user this particular site is not mobile friendly.After years of struggle and updations google became more powerful and successful. According to reports google receives about more than 2 billion online searches on a daily basis. Behind every success there is always a story about hard work and struggle. Now you know that story and here I conclude the topic about history and evolution of search engine optimization..😊
