Search Engine Optimization (SEO) is synonymous with Google now. If you have been in the internet space for a long time, you must be familiar with one or the other aspects of SEO. But due to the significant SEO evolution, the SEO we refer to now is quite different from what it originally was.

In fact, even today, each person seems to have a different definition of SEO in their mind. That is because SEO has and is changing so rapidly that it becomes a daunting task to even keep track of the changes. 

You never know whether you’re stuck in the past or the present version of SEO with the future looming increasingly nearer.

In this article, we will take you through the SEO evolution, the history of SEO, and future SEO trends.

What is SEO?

SEO is the process of improving your website so that it ranks higher in search results. There are various techniques that help in ranking a website. These techniques have evolved over the last few years and this SEO evolution has led to newer and more refined techniques to help rank your website in search results.

Over the years, the key elements for ranking a website have included: 

  • Meta title and description
  • Appropriate keywords
  • Internal and external linking
  • H1 tags
  • Images with alt tags, etc.

Search engines are the driving forces of SEO and as search engines are becoming better and incorporating new trends, so is SEO evolving alongside the process.

Tracing the Ever-Evolving SEO

The concept of SEO now is very different from its initial days. SEO initially focused on the listing, link building, keywords, and using some controversial tactics to rank higher in the search results. The definition of SEO started changing after Google began to refine SEO techniques. Today, the ever-evolving SEO comprises a range of factors that include keywords and links. It also looks at the content quality, search context and takes a human-first approach.

There are still many challenges; however, they are better than before.

The Past Present and Future Of SEO

SEO is constantly evolving. But, how did it all start?

The history of Search Engine Optimization dates back to 1991 when Tim Berners-Lee launched the world’s first website. Let’s go down memory lane to understand SEO evolution, i.e., the history of SEO and future SEO trends.

The 1990s

This was the era of search engines (Yahoo, AltaVista, anyone?), and the landscape was quite competitive. There wasn’t a formal name for SEO, but websites competed to rank in directories, listing sites, and search results.

It was also at this time, in 1998, that paid searches and sponsored links were introduced by, which Yahoo later acquired.

Key factors for ranking included:

  • Enough text and keywords
  • Internal and external links
  • Proper HTML tags
  • Relevant content

However, the emphasis on on-page SEO factors like keywords made tactics like keyword stuffing prominent.

The early 2000s

This was the era of Google. SEO history and even the future of SEO are incomplete without mentioning Google.

The Google Revolution started because, well, Yahoo! Yahoo!, at that time, was a household name, and Google was just a speck in the internet space. Yahoo! partnered with Google and let them power their organic search. (Oops!) Result? All Yahoo! searches had a ‘Powered by Google’ text at the bottom. That’s how Yahoo! helped Google gain popularity, and the rest is history!

The Google Revolution


Google forever changed how information was retrieved through its groundbreaking algorithms for crawling and ranking pages. While earlier, most of the content was ranked based on on-page factors, now the sites were ranked based on both on-page and off-page factors. Google looked at external links, anchor texts, etc., as key components to rank sites. And this, to a great extent, helped curb the problem of keyword stuffing.

However, this led to problems and resulted in an industry of link building and buying links. In 2000, Google also launched Adsense ads, and these paid search results would appear at the top and bottom of the search engine results page.

In 2003, Google acquired and launched Adsense that helping advertisers place contextual ads on publisher sites. This simple monetization technique through websites led to a surge in blogs & bloggers.

Mid to late 2000s

This was the era of localized searches; universal search results in the form of images, videos, news, social media; Google Suggest, and noteworthy Google updates.

Google search results became more geographical as well as personalized in nature. That is, for the first time, the search results of one person varied from the search results of another.

Google also launched two major updates, Jagger and Big Daddy, to curb black hat link-building practices along with its ‘rel=nofollow’ attribute.

Another significant event during this time happened in 2006 when Google acquired YouTube. Google also launched Google Analytics and Webmaster Tools that websites rely heavily on for analytics and crucial data.

In 2007, Google launched two significant updates, Vince and Caffeine, that helped clean up the mess in the Internet space. The update led to a dramatic shift in rankings, where websites of big trusted brands were positioned higher than smaller less-established brands.

2009: Microsoft launched Bing.


This was the era of social media, user-focused content, mobile-first searches, and Google core updates.

This was the time when social media dominated the Internet and while social media doesn’t directly impact SEO, it indirectly validates content through signaling. 

In 2011, Google launched Schema markup to understand the context of search queries. Along with that, it launched Panda & Penguin, two important algorithm updates to define and rank high-quality sites. Further, updates like Knowledge Graph & Humming Update made searches even more contextual and convenient for people.

2015: Year of the mobile — Mobile searches were higher than desktop searches for the first time ever in Google.

2016: One of Google’s biggest updates, RankBrain, propelled its way towards the use of machine learning.

2017: Google declared a Machine learning-first company by Sundar Picha, CEO of Google.

Present & Future of SEO

Today, SEO techniques don’t just depend on on-page techniques but rather on the speed & experience of the site, audience retention, and the quality of content.

Mobile-first searches, voice search, and topical content are some trends emerging in the present. The quality of content matters more than the quantity and it is important to understand the algorithms that are shaping the results of the rankings. 

The future of SEO will be driven by machine learning and intelligent search recommendations. So, taking a holistic approach to SEO is vital.

Key Takeaways

Search engines started as a way to retrieve information and search engine optimization was practiced with the core idea of providing the most relevant information to people.

The history of SEO dates back to 1991 when  Tim Berners-Lee launched the world’s first website. In the 1990s, most of the search engine optimization techniques were on-page techniques like keywords, meta titles & descriptions, tags, and links.

As Google led the search engine revolution in the early 2000s, the quality and techniques of search engine optimization also started evolving.

Google forever changed the way information was retrieved through its groundbreaking algorithms for crawling & ranking pages. While earlier most of the content was ranked based on on-page factors, now the sites were ranked based on both on-page and off-page factors.

This was followed by paid searches (AdWords ads), contextual ads on publisher sites (Adsense ads), localized searches, and universal search results in the form of images, videos, news, social threads, etc.

But black hat SEO techniques posed a threat alongside these developments. Google tried countering it with its algorithm updates and over time the search results have become more contextual, user-friendly, and authentic.

Mobile-first searches, voice search, and topical content are some trends emerging in the present. The future of SEO will be driven by machine learning and intelligent search recommendations. So, taking a holistic approach to SEO is vital.


The history of SEO reveals that SEO is never constant. It is always evolving. From mere information retrieval to intelligent searches and machine learning techniques, SEO has come a long way.

With time, SEO has become more and more human and now relies less on keywords and more on the authenticity of the site, quality of content, and the context of searches.

The sooner we understand the changing nature of SEO and prepare ourselves and our skills accordingly, the better we can ride the wave of change.
