What is semantic SEO and why is it important for search in 2022?

As search engine technology has progressed, semantic search has become increasingly important for SEO. Learn what it is, why it is important, and how to make it work for you.

Many things have changed since 2010, when SEO was all about acquiring as many backlinks as possible and stuffing as many keywords as possible.

The focus in 2021 will be on understanding purpose and action, as well as the context – semantics – that surrounds them.

As a result, our understanding of search engines has grown, and we’ve modified how we optimize for it. The days of reverse-engineering content to improve its ranking are gone, and discovering keywords is no longer sufficient.

Now you must know what those terms imply, give rich information that contextualizes them, and have a strong grasp on user intent.

These factors are critical for SEO in the age of semantic search, when machine learning and natural language processing aid search engines in better understanding context and users.

You’ll discover what semantic search is, why it’s important for SEO, and how to optimize your content for it in this article.

What Is Semantic Search?

Semantic search refers to a search engine’s attempt to produce the most accurate SERP results possible based on the searcher’s intent, query context, and word relationships.

  • People ask and answer questions in a variety of methods, languages, and tones.
  • The nature of search queries might be confusing.
  • It is necessary to comprehend the links between words.

Interactions between entities, as well as human choices and relationships, are crucial.

Google spends a lot of money on patents in this field. This works when a user types in [top 10 movies of 2021] and Google offers a list of options/websites for them to check out.

Semantic search, in layman’s terms, aims to grasp natural language like a person would.

“What is the largest mammal?” you may ask a buddy, for example. “How large is it?” she asked after that. Your companion would realize that “it” is a blue whale, the world’s biggest animal.

The context of the second question was not understood by search engines prior to 2013.

Instead of responding to the question “How large is a blue whale?” Google would look for certain keywords in the phrase “How big is it?” and return webpages that included those phrases.

Today, you’ll see a new result with a highlighted excerpt and a better grasp of the context behind the query, as well as additional information.

Google may also use semantic search to differentiate between distinct entities (people, places, and things) and interpret searcher intent based on a range of characteristics, such as:

  1. User search history.
  2. User location.
  3. Global search history.
  4. Spelling variations.

This all helps Google achieve its objective of providing a better user experience by delivering quality information and prioritizing relevant content results.

A Brief History of Semantic Search

The Knowledge Graph

The Knowledge Graph, initially introduced in 2012, was Google’s first step toward emphasizing entities and context over keyword strings – or, as Google put it, “things, not strings.”

The Knowledge Graph laid the groundwork for future large-scale algorithmic advances.

The Knowledge Graph gathered information that was considered public domain (e.g., the distance to the moon, Abraham Lincoln’s presidential term, the cast of “Star Wars,” etc.) as well as the qualities of each object (people have birthdays, siblings, parents, occupations, etc.).


Google’s Hummingbird upgrade, released in 2013, is widely regarded as the start of the modern semantic search era.

Hummingbird employs natural language processing to guarantee that “pages that match the meaning do better than ones that match only a few words.” In practice, this implies that pages that better fit the context and intent of searchers will rank higher than ones that repeatedly repeat context-less terms.


Google introduced RankBrain in 2015, a machine learning system that serves as a ranking element as well as a smart query analysis AI.

RankBrain, like Hummingbird, tries to figure out what users are looking for. The machine-learning component of RankBrain is the key distinction between the two.

RankBrain is constantly learning and evaluating the best-performing search results, looking for commonalities across the pages that visitors find useful.

As a consequence, even if a website doesn’t include the precise terms from the query, RankBrain may consider it a “excellent response” to the query.


BERT (Bidirectional Encoder Representations from Transformers) was launched by Google in 2019. This focuses on better understanding intent and the context of conversation search.

BERT makes it easier for consumers to access useful and reliable information.

According to Google, this was the biggest step forward in search in the last five years and one of the biggest in history. It directed advertisers to focus on longtail inquiries and phrases with more than three words, as well as ensuring that content answers consumers’ requests.

It also meant that SEO experts had to change their attention to writing for people, with clear, succinct, and understandable material.

How Does Semantic Search Impact SEO?

Users Turn to Voice Search

Because of the growth of voice search, semantic search has progressed significantly.

Mobile speech instructions have become popular, with 33 percent of high-income households utilizing voice commands on devices other than their smartphones.

Voice search optimization differs from traditional SEO in that you must go right to the point (for intent-based searches) and make your content conversational.

What You Can Do

Before digging into more technical information, provide content that answers a typical inquiry simply and concisely at the top of the page.

Use structured data to aid search engines in comprehending your content and context.

A sports goods store, for example, may create a checklist of things to bring for a day trek, along with information on area species, fishing and hunting rules, and emergency contact information.

Focus Shifts from Keywords to Topics

It’s past time to abandon keyword-driven content.

Instead, choose big themes in your field that you may explore in greater depth.

The objective is to provide materials that are comprehensive, unique, and of high quality.

What You Can Do

Consider generating “ultimate guides” and more complete resources that your readers will find useful instead of dozens of small, disjointed pages, each with its own topic.

Searcher Intent Becomes a Priority

One of the most effective techniques to keyword targeting is intent targeting rather than keyword targeting.

You may come up with a list of subjects to generate content around by looking at the searches that bring users to your website.

What You Can Do

Make a list of keywords and categorize them according to the user’s purpose.

[iPhones vs. Android battery life] and [compare Apple and Samsung phones], for example, plainly fit under the umbrella goal of [compare smartphones].

In contrast, [where to buy iPhone 12] and [top Samsung Galaxy offers] both convey a desire to buy.

Instead of developing content around specific keywords or broad subjects, once you understand searcher intent, start creating material that precisely meets their purpose.

Technical SEO is just as important as content SEO.

Despite Google’s shift from strings to objects, the algorithm isn’t yet intelligent enough to deduce meaning or comprehension on its own.

You must continue to improve your site and assist Google in comprehending your material.


Yes, keywords are still important. Use a content analysis tool to look for frequently asked queries and associated long-tail keywords that you may use in your article. As long as it fits organically, include keywords in your title tags, URL, body, header tags, and meta tags.

Link building

Backlinks from authoritative sources are still one of the most essential ranking factors. Make material that organically draws links a priority. Also, don’t forget to generate deep linkages to other useful material you’ve developed using suitable internal linking structures.

Structured data

To help clients locate your business and search engines index your site, use Schema markup. You may also use review and organization markup to provide further detail.


When feasible, avoid redirects and instead rely on 301 redirects for missing pages. Per page, there should be no more than one redirect. Also, for multiple versions of your website, use rel-canonical tags.

Site speed

Minimize resources, compress pictures, use browser caching, and follow Google’s checklist for website performance optimization.

Optimize site structure

Maintaining a logical site structure can aid search engines in indexing and understanding your content’s connections. Sensible site architectures also boost UX by guiding people around your website in a logical manner.

Focus Shifts to User Experience

In the age of semantic search, user pleasure should guide all of our SEO activities.

Google values customer pleasure and is constantly fine-tuning its algorithm to better understand and please searches.

UX should be a priority for SEO practitioners as well.

What You Can Do

Improve page speed as much as possible, ensure your mobile site is optimized (particularly now that Google indexes mobile sites first), and monitor metrics like bounce rate and session duration.

Run A/B trials whenever you believe you can enhance anything to see if you can increase engagement.


Understanding how Google intelligently recognizes intent is critical to SEO. When generating content, keep semantic search in mind. In addition, keep in mind how this relates to Google’s E-A-T principles.

Poor content and outdated SEO tactics will no longer suffice, especially as search engines improve their knowledge of context, connections between concepts, and user intent.

Content should be relevant and of good quality, but it should also focus on the purpose of the searcher and be technically optimized for indexing and ranking.

If you can achieve that equilibrium, you’re on the correct course.
