Semantic Search and Why It Matters for SEO: A Guide for Online Businesses

by | Sep 6, 2024 | blog, Business, Content Marketing, writing

Search engine optimization, or SEO, has evolved continuously since its inception in the early days of the commercially viable internet. A full history of this evolution (or even a decent summary, frankly) would be a book-length endeavor, so suffice it to say the days when stuffing your website with the right keywords to guarantee a spot at the top of Google search results are long gone.

Today, Google’s algorithms are smarter. While some tech influencers are quick to nebulously chalk every advancement up to “AI” without further elaboration, newer technologies like semantic search are totally different, and maybe even more meaningful, than the large language models (e.g., ChatGPT) that have dominated the tech journalism landscape for several years now. 

What Is Semantic Search?

“Semantic search” is not a specific product or platform but a term that refers to the way Google and other modern search engines interpret the meaning and intention behind the words in a search query. Prior to the advent of semantic search technologies, Google and its competitors took a more literal approach to search, essentially trying to match website keywords to search keywords in hopes of delivering relevant results.

Today, Google strives to deliver a web search that can “understand” the user’s wants and needs. Because of this fundamental change in the way we think about web searches, semantic search promises an improved user experience that goes far beyond crudely running search terms against a database.

Semantic Search in Practice

If you searched the phrase “pizza near me” using old-school, Web 1 search technology, you would indeed receive a list of pizza places, but if you’re searching late at night, many might not even be open. Perhaps you’ll get a link to a pizza place that was shuttered by the health department three years ago, but the website, hours, and contact info were never taken down. 

Worse, shady pizza places–even shady pizza places several states away–might be able to “hack” their way into your top search results just by packing their website with key phrases like “pizza near me” and “closest pizza places” to deliberately prey on people’s misunderstanding of search technology. 

With semantic search principles employed, however, many of these worries are mitigated or overcome entirely. Today, Google knows that a search for “pizza near me” should only return results in the user’s geographic area, and it can even prompt the user to act if the search service does not have the necessary access to the device’s location data. It also knows to prioritize restaurants that are currently open because people who search for pizza often intend to order it in the immediate future.

One great thing about semantic search is that, because it is so focused on the concept of understanding, it keeps search engines primed to improve and scale indefinitely alongside advancements in artificial intelligence, large language models, and data analytics. For many in the tech space, the next logical step seems to be pairing these semantic search principles with custom AI “assistants,” leading to an even more personalized and targeted search experience for each user.

Google’s Semantic Search Ecosystem

While semantic search itself is a high-level concept rather than a specific technology, you will probably run into a few key pieces of the sprawling Google machine as you continue learning about semantic search and its likely effects on your SEO strategies. These include:

  • Knowledge Graph – A knowledge graph is a widely applicable data tool used in tech and many other industries. It involves creating a model of a semantic network that can help people (or machine learning systems) better understand the relationships between the various data points, or nodes, that make up the network. Wikipedia is an example of a popular product that uses knowledge graphs in a user-facing way. Google search also employs a knowledge graph extensively–one that includes over five million objects.
  • Hummingbird – Hummingbird was the code name given to a major update to Google’s search algorithm circa 2013. In some ways, this marked the beginnings of what we call semantic search today, as Google pivoted away from keyword calculations and began striving to analyze the context and intent of a user’s search.
  • Voice Search – It’s interesting to note that the pivot to understanding-based semantic search coincides with a rise in voice-based searches, such as those conducted through a personal assistant app on a smartphone, or a smart speaker device. The two concepts make a compelling pairing, as users relying on voice search tend to ask questions in a more conversational way versus those typing their search queries. Even as technological capacity increases, both tech users and the tech itself are trending towards more natural, human language.
  • RankBrain – RankBrain is essentially the engine behind Google’s industry-owning search platform. It is best described as a comprehensive system of algorithms and programs to analyze search terms and patterns and then use that understanding to deliver more useful, accurate results.

Semantic Search and Your SEO Strategy

You’re likely wondering what this means for your own website and its SEO. In short, having well-written content will be much more important than calculating keyword density. “Well-written” can be a subjective term, but you’ll want to make sure your websites, posts, and blogs are authoritative, reliable, concise, and engaging. Going forward, Google will rank these well-written websites higher, while websites relying on old-school keyword-packing strategies will suffer for their failure to modernize. 

If you’re concerned about adapting to this context-rich future of search, here are some concepts to keep in mind:

  • Focus on User Intent – Don’t just aim to understand what your audience is searching for–aim to understand why they’re searching for it. You can then use your web presence as a platform to answer those questions, which creates value for your customers, builds trust in your brand, and–in the age of semantic search–improves your website ranking. Don’t just think about intent broadly; analyze the specifics and meet the implied need as exactly as possible. For example, someone searching “best work boots” probably wants links to good work boots they can purchase–not a 2,000-word, keyword-dense article meandering around the topic of what makes a good work boot.
  • Topic Clusters Are In; Keywords Are Out – Instead of generating a list of keywords and writing a blog post or two focusing on each one, plan your content more intelligently around a cluster of key topics. Start by making a concise “pillar” page for each of these topics that will help keep your content well-organized and give your website a sense of intuitive flow.
  • Optimize for Voice Search – People today are using their phones and smart speakers to ask search engines questions in natural, conversational language. Seize the opportunity for your content strategy to leverage this paradigm shift. Make sure your content is easy to read and answers common questions in a direct way. FAQ pages are one way to lean into this concept, but also keep the question-and-answer format in mind when crafting your other content.
  • Invest in Your SEO – In truth, it isn’t always realistic to expect yourself to run a successful business and become an SEO expert all at the same time–and that’s okay! If you need an extra set of hands working on your SEO or content strategy, help is available. Better Content Matters offers powerful content creation and SEO campaigns informed by a peerless understanding of Google’s latest algorithm updates.
  • Diversify Your Strategy – While Google still has an immense majority of the global search market captured today, it can be useful to remember that not everyone searches through Google. If you have a target audience that prefers finding information through some other platform, consider tweaking your strategy accordingly.
