Search Engine Optimisation

The ultimate search engine... would understand exactly
what you mean and give back exactly what you want.

Larry Page


If a tree falls in the woods, but nobody's there to hear it, does it make a sound? Probably not.

A strange analogy maybe, but if your website doesn't rank well for relevant search terms on the likes of Bing and Google, no one will know you, or your business exists. In today's world, SEO is more important than ever.

In fact, according to a recent study, marketers see SEO as becoming more effective, with 82% reporting effectiveness is on the rise and 42% of the same group stating effectiveness is increasing significantly.

Since first rearing its head, the notion of search engine optimisation (SEO) has evolved massively, changing the way brands and businesses inspire, campaign and connect with their target audience.

But before we delve any deeper, you might be asking yourself...

What is SEO?

Search Engine Optimisation is the name given to any activity that exists to improve search engine rankings for search engines like Google. For instance, Google ranks or references pages it considers to be relevant and authoritative. Authority is measured by analysing the number and quality of links from other web pages, quality of content, and overall relevance to a search term.

you maintain healthy link profile

The art of SEO can seem mysterious,

but in today’s world it's about building high quality content and developing a user experience that’s as human friendly as possible. Google has evolved its algorithm over the years to eliminate nasty ‘blackhat’ (playing dirty and cheating) tactics that compromise a user’s search experience. But it hasn’t always been that way.

SEO history timeline


Evolution_of_SEO Final

In July 1945, Dr. Vannevar Bush, the (back then) director of the Office of Scientific Research and Development, published an article in The Atlantic proposing the compilation of a 'collection of data and observations, the extraction of parallel material from the existing record, and the final insertion of new material into the general body of the common record'. In essence, an analogue version of Google.

SEO wasn't quite a thing, as it were, by this time; however, Eric Ward publicised the notion of looking for people you want to link to based on relevancy and connection. A big part of Google's ranking factor, even today.

Google launched in September of this year and changed the face of the web forever.

Talking again of blackhat SEO tactics: over the years online marketers learned that 'stuffing' their web pages full of relevant keywords to rank well on Google, so the search engine fought back with its first major Google algorithm. Bestowed with the name FLORIDA, this development prevented the adoption of blackhat tactics and enhanced the user experience ten-fold.

Search engines, chiefly Google, continued to evolve, and this year, the search engine launched its “rel=nofollow” attribute, a page level meta tag that stops page rank and authority from being passed on. This helped webmasters to clean up poor quality links that had been put in place to manipulate search engine rankings. Later in the same year, the Jagger and Big Daddy algorithms were launched to tackle link farming and other black hat SEO tactics.

Google released something known as the Suggestion Box. This service gave SEOs the power to gain further insights into how users surf the web and interact with certain pages, shifting the focus onto the consumer.

Google algorithm Panda 1.0 was released to the digital world affecting over 12% of search engine rankings. The search engine started to focus a lot more effort on site content, and sites with weak, poor quality or irrelevant content took a real hit.

The Google Penguin update was released targeting websites that violated Google's Webmaster Guidelines. In particularly websites that were buying links or obtaining them through link networks designed primarily to boost Google rankings.

Google evolved to reward websites that placed their efforts into engaging users by answering their questions with rich, information and original content. Inbound marketing became the order of the day, resulting in a stronger focus on blog posts and social media marketing, among other disciplines.

Google introduced a sophisticated machine called RankBrain in a bid to deliver even smarter, more targeting search results. Did you know? As a machine learning technology, RankBrain learns like a human does. In fact, an experiment conducted by Google, in which Google's search engineers went head-to-head with RankBrain in a test, showed that RankBrain scored 80%, beating its human counterparts by 10%. Mind Blowing stuff, to say the least.

Google's Head of Search, Andrey Lipattsev, confirmed that the search engine's three most vital ranking factors are: links, content, and RankBrain.

Duplicate content is a big no-no, as is keyword stuffing, buying cheap links, and any other lazy kind of search activity. Today's search engines won't tolerate such behaviour, so SEO has to focus on the user - no shortcuts.

A huge driver of this change comes down to Google's algorithms.
Let's take a quick look at the algorithms that haven't yet been mentioned, but served to change SEO in a big way…
