The higher the number of inbound links a website had, the better would be its PageRank. Google also provided a toolbar on Internet Explorer for webmasters to check the PageRank effectively. Adwords had also begun during this time and you could see paid results alongside organic search results.\u00a0<\/span><span>At this time link quality was not measured. Webmasters were not really following a &#8216;White-hat&#8217; way to get rankings as suggested by Google.\u00a0<\/span><span>It is then that Google started off with its algorithm updates.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"florida-update-%e2%80%93-2003-2004\"><\/span><span>Florida Update &#8211; 2003-2004<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div style=\"text-align: justify;\"><span>Google rolled out the Florida update in the year 2003. This is when quite a few sites lost their search engine rankings. Many sites who were doing keyword stuffing got penalized. 2003 was also the year when Google acquired Blogger.com and created the blog monetizing platform Adsense. <\/span><\/div>\n<div style=\"text-align: justify;\"><span>The development did pave the way to a blogging revolution of sorts. But at the same time, there were many blogs which were creating poor quality and thin content and using Adsense to monetize and make quick money. It was 2004 when Google started considering geographic intent when providing results for search queries. This was when local SEO was born. The same year Google also initialized personalized search by utilizing searcher data such as search history and preferences.\u00a0<\/span><\/div>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"no-follow-links-%e2%80%93-2005\"><\/span><span>No-Follow Links &#8211; 2005<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div style=\"text-align: justify;\"><span>This was the year of two key developments: Introduction of no-follow link attribute and Google Analytics.<\/span><\/div>\n<div style=\"text-align: justify;\"><span>This year also saw the advent of Google Instant &#8211; the technology helped improve search engine results while social signals became an important ranking factor.<\/span><\/div>\n<div style=\"text-align: justify;\">Some of the key updates during this time included Jagger and Big Daddy.

The Penguin update penalized websites with irrelevant and bad quality links. The update dealt with all kinds of sites that purchased links from spammy blogs or directories. Here is a brief history of Google Penguin Updates till date and how you can protect yourself from it:<\/span><\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\"><strong>Penguin 1.1 (March 2012)<\/strong><\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">This was not exactly an update to Google&#8217;s algorithm. This Penguin release punished all those spammy sites which were missed in the original release. At this time, the webmasters who had worked on improving their link profiles saw their rankings go up.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\"><strong>Penguin 1.2 (October 2012)<\/strong><\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">This release too provided fresh rankings and penalized English as well as Non-English International sites.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\"><strong>Penguin 2.0 (May 2013)<\/strong><\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">This was a major algorithm update. Google crawlers now started checking websites more thoroughly. They checked suspicious sites beyond their home page and category pages.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\"><strong>Penguin 3.0 (October 2014)<\/strong><\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">This release too refreshed the rankings and penalized sites which had escaped the earlier updates. Webmasters who had worked on their link profile saw their rankings improve, with this update as well.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\"><strong>Penguin 4.0 ( September 2016)<\/strong><\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">Penguin now became a part of Google&#8217;s core algorithm. It became a real-time update and if you worked on your link profile after this update, you would not have to wait for the next update to see better search rankings. Post this update Penguin would not punish sites with spammy backlinks, rather it would consider spammy backlinks equivalent to no backlinks.<\/div>\n<div>\n\t\t\t<div class=\"course-cta\">\n\t\t\t\t<div class=\"title\"> Wish to Become <strong>World-Class SEO Expert?<\/strong> <\/div>\n\t\t\t\t<div class=\"sub-title\"> Sharpen Your Search Engine Optimization Skils <\/div>\n\t\t\t\t<div class=\"btn\">\n\t\t\t\t\t<button class=\"enrollBtn\"> Attend Live Orientation Session <\/button>\n\t\t\t\t\t<a class=\"amp-btn\" href=\"#gform_wrapper_286\"> Attend Live Orientation Session <\/a>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\n\t\t\t<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\"><strong>Things to Remember about Penguin<\/strong><\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">\n<figure id=\"attachment_110728\" aria-describedby=\"caption-attachment-110728\" style=\"width: 301px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" src=\"https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Penguin-Update-262x300.png\" alt=\"Brief History of SEO\" class=\"wp-image-110728 \" width=\"301\" height=\"345\" title=\"\" srcset=\"https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Penguin-Update-262x300.png 262w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Penguin-Update-894x1024.png 894w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Penguin-Update-131x150.png 131w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Penguin-Update-600x688.png 600w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Penguin-Update-220x252.png 220w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Penguin-Update-436x500.png 436w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Penguin-Update-595x682.png 595w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Penguin-Update-1080x1238.png 1080w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Penguin-Update-980x1123.png 980w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Penguin-Update-480x550.png 480w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Penguin-Update.png 1117w\" sizes=\"(max-width: 301px) 100vw, 301px\" \/><figcaption id=\"caption-attachment-110728\" class=\"wp-caption-text\">Google penguin update<\/figcaption><\/figure>\n<\/div>\n<div style=\"text-align: justify;\">After Penguin, you need to ensure that your backlinks are relevant and come from sites that have high-quality content. You need to have diverse anchor texts for each of your backlinks. You should not use targeted keywords in your anchor texts &#8211; rather go for anchor texts that make your links more natural. Buying links and link-building automation are not advisable as well. All you can do is aim for quality backlinks and brand mentions &#8211; the trick is to consistently pitch interesting story ideas and tips to journalists.<\/div>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"introduction-to-the-knowledge-graph-%e2%80%93-2012\"><\/span><span>Introduction to the Knowledge Graph &#8211; 2012<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div style=\"text-align: justify;\"><span>Google introduced the knowledge graph to further enhance the quality of search results. It started showing knowledge panels, boxes, and carousels to online searchers. This was another of Google&#8217;s technical developments towards making search more intelligent. It was the search engine&#8217;s move to go beyond keyword-based search &#8211; to a more semantic, meaningful approach. Google now started understanding the meaning of search queries and their relevance to real-world entities. \u00a0This helped the search engine to predict the intent behind searcher queries and provide the right answers to complex questions from online searchers.<\/span><\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">\n<figure id=\"attachment_110726\" aria-describedby=\"caption-attachment-110726\" style=\"width: 672px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" src=\"https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Unknown-11.png\" alt=\"Brief History of SEO\" class=\"wp-image-110726 size-full\" width=\"672\" height=\"388\" title=\"\" srcset=\"https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Unknown-11.png 672w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Unknown-11-300x173.png 300w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Unknown-11-150x87.png 150w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Unknown-11-600x346.png 600w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Unknown-11-220x127.png 220w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Unknown-11-595x344.png 595w, https:\/\/www.digitalvidya.com\/blog\/wp-content\/uploads\/2018\/02\/Unknown-11-480x277.png 480w\" sizes=\"(max-width: 672px) 100vw, 672px\" \/><figcaption id=\"caption-attachment-110726\" class=\"wp-caption-text\">Knowledge graph example<\/figcaption><\/figure>\n<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"hummingbird-%e2%80%93-september-2013\"><\/span><span>Hummingbird &#8211;\u00a0<\/span><span>September 2013\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div style=\"text-align: justify;\"><span>The algorithm update from Google was designed to address natural language and conversational search queries. The Hummingbird update came as an improvement in Google&#8217;s search technology and would impact 90 percent of the searches worldwide.

From here on, mobile-friendliness of web pages would become a key ranking signal. \u00a0This update affected search rankings on mobile devices only, on all languages globally and applied only to individual pages of a website.

RankBrain uses Artificial Intelligence to make sense of searcher queries. The update is applicable to all languages and to countries across the globe. The technology is most active in case of new and unknown searcher queries. RankBrain basically works as a Natural Language Processor, that attempts to understand the meaning of searcher query just like humans do and then provides the best solution to it.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"possum-update-%e2%80%93-2016\"><\/span>Possum Update &#8211; 2016<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">This was Google&#8217;s local algorithm update that happened in September 2016. The update mainly impacted local search results and results shown through Google Maps. Prior to this update, many businesses that were just outside the city limits found it very difficult to rank for keywords that included the city name. Google Maps also showed them to be outside of the city. All of this changed after the Possum update. This update also ensured that businesses with the same address in a business category were being filtered out in the search results. One more essential aspect of this update was that local search results started depending on the searcher&#8217;s physical location. Studies showed that after this updated Google&#8217;s organic filter and local search filter work independently of each other.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"over-to-you\"><\/span><span>Over to You<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div style=\"text-align: justify;\"><span>The history of SEO, as you can see, has been quite exciting.
