“Issues, not strings.”
This was Google’s well-known quote referring to the launch of its Information Graph again in 2012.
It meant that, for the primary time, Google’s algorithm may comprehend real-world entities (folks, locations, issues, and many others.) as an alternative of simply matching strings of key phrases.
It was additionally the delivery of entity search engine marketing, which laid the inspiration for AI-powered platforms like ChatGPT, Perplexity, and Google’s AI Overviews.
That’s as a result of information graph affiliation is how machines like massive language fashions (LLMs) can correctly determine entities.
With the prevalence of AI Overviews and AI search instruments, entrepreneurs want to emphasise entity recognition and entity reinforcement over uncooked key phrase analysis.
Why?
As a result of establishing your self as a related entity in your area of interest is the way you construct sufficient credibility to earn AI citations and model suggestions.
This marks a stark shift from the largely keyword-focused days of legacy search engine marketing.
Within the following information, we’ll cowl how search advanced from key phrases to entities, together with how one can put entity search engine marketing into follow at this time.
The Key phrase Period (Pre-2013, Early 2000s)
Let’s begin by analyzing the key phrase period of search engine marketing, which is every little thing that occurred earlier than Hummingbird’s introduction in 2013.
Whereas 2012’s Information Graph was a strong step within the course of semantic search, Google didn’t make semantic understanding a full-blown a part of its algorithm till 2013.
Earlier than that, the way in which search algorithms ranked content material was fairly primary.
Particularly, Google’s algorithm relied on issues like exact-match key phrases and authority indicators coming from backlinks.
The primary takeaway?
Key phrases have been king, and the extra exact-match key phrases you possibly can stuff inside your content material, the higher.
It was additionally commonplace follow to jam key phrases inside meta descriptions and meta tags.
Whereas skilled entrepreneurs all the time centered on content material high quality to make sure a strong consumer expertise alongside prime rankings, the sheer simplicity of the system attracted a number of spammers and ‘black-hat’ practitioners.
Even when the inclusion of repetitive key phrases made content material awkward, issues like content material high quality and helpfulness have been typically an afterthought (if even thought-about in any respect).
The key phrase period’s formulation for fulfillment
The formulation went one thing like this:
- Conduct key phrase analysis to find key phrases that have been trending along with your audience. Let’s use the instance key phrase ‘dental providers St. Petersburg’.
- Entrepreneurs would then create content material containing the precise phrase in strategic areas just like the title, first 100 phrases, and quite a few occasions within the physique of the content material (like ‘Offering the most effective dental providers St. Petersburg has ever seen,’ and many others).
- Pair the keyword-heavy content material with a big quantity of backlinks.
For a few years, this recipe produced constant rankings, even when the content material wasn’t very useful.
Google was effectively conscious of the rampant rise in spam, which is why it will definitely moved towards an entity-based mannequin as an alternative of specializing in key phrases.
Within the meantime, Google launched the Penguin replace as an try and curb the quantity of manipulative content material showing in its outcomes.
Step one of the evolution into entity search engine marketing was the introduction of the Information Graph in 2012, however the first main change got here the very subsequent 12 months.
The Rise of Semantic Search (2013 – 2015)
In 2013, Google launched the Hummingbird replace, which added semantic understanding to Google’s core rating system.
The beforehand launched Information Graph was solely a search outcomes characteristic and didn’t influence the rating of outcomes.
It was the primary time that Google’s algorithm had any type of pure language processing. Earlier than Hummingbird, phrases have been simply phrases. The algorithm had no means of decoding the that means behind the phrases or the connections the phrases needed to different entities.
Out of the blue, customers have been in a position to make use of longer, extra conversational queries on Google, and the algorithm was capable of perceive what they meant.
Hummingbird additionally launched the idea of search intent, or the ‘why’ behind a consumer’s search. The algorithm may now inform if a consumer wished to purchase one thing, discover info, or navigate to a sure web site.
This led to an improved consumer expertise and better ranges of consumer satisfaction with Google’s search outcomes.
It was additionally not as simple to recreation the system, which made key phrase stuffing methods much less efficient.
As a substitute of cramming key phrases into content material, it was extra necessary to provide content material that was really related and useful.
AI-Powered Entity-Based mostly Search (2015 – Current)
2015 noticed the discharge of RankBrain, which formally launched AI and machine studying to Google’s rating system.
Whereas Hummingbird was adept at decoding most searches, it was thrown off by some forms of long-tail queries. RankBrain was launched as a part contained in the broader Hummingbird algorithm to boost its semantic capabilities.
It’s additionally capable of be taught from consumer conduct in real-time, and it adapts accordingly. For instance, if RankBrain notices that you simply select sure forms of outcomes for comparable queries, it’ll prioritize these pages for future searches.
In that sense, RankBrain is ready to personalize every outcomes web page primarily based on consumer preferences.
With the Information Graph, Hummingbird, and RankBrain on board, Google was lastly beginning to look extra like an entity-based search engine than a keyword-focused one.
But, the ultimate transition into full-fledged entity search engine marketing didn’t come till the introduction of Google’s AI Overviews (AIOs) in 2024. At this level, AI search instruments like ChatGPT already existed for a number of years, however they paled compared to Google’s recognition.

The keyword-based methods of the previous have been all of a sudden rendered ineffective, and visibility started to hinge on AI citations as an alternative of key phrase rankings.
That’s as a result of the LLMs that energy AI search instruments use information graphs to determine entities and perceive the relationships they share with each other. This immediately ties into how they generate solutions, pull sources, and weigh credibility.
In different phrases, entity recognition is how algorithms and LLMs reply the query, “Which factor do you imply?”
For example, think about that an LLM encounters the phrase Paris in a sentence. Entity-wise, this might confer with a number of issues.
There’s the town in France, however there’s additionally the movie star Paris Hilton, the Greek mythological determine Paris, and different cities named Paris, simply to call a number of.
