What is a Semantic Search and How to Use It?

Semantic search

In the past, search engines were not smart enough to understand the meaning of words. That meant that the results you got back were often unrelated to what you were actually looking for. However, today’s search engines have improved their understanding. They can analyze words and their relationships to each other in order to provide more relevant results. In this article, we will go over what semantic search is and how it works so that your website benefits from it too!

What is Semantic Search?

Semantic search is the process of searching for meaning. It involves looking at the context of what you are searching for rather than just the words themselves.

Semantic search engines use natural language processing (NLP) to understand what you are asking for so that they can give you more accurate results based on their understanding of what those words mean to humans in context. This means that a semantic engine would understand that “cat” means “domestic feline” and not “a card game” or any other interpretation. In contrast, regular keyword searches wouldn’t be able to tell these two uses apart without additional information such as synonyms or definitions included with each query result link as well as some kind of user feedback mechanism like thumbs up/down buttons shown next to links when clicked on by someone using your site’s interface–which isn’t always practical because most users won’t go through all this extra effort so that they can find something quickly!

Algorithm’s Ability to Analyze Words

The algorithm works by analyzing words. It understands that “cat” is a noun, and “dog” is also a noun. The algorithm also knows how to find the relationship between these two words: they both refer to animals.

The algorithm can also detect hidden meanings behind words–for example, if you search for “pizza,” it will know that you want pizza from the restaurant rather than homemade pizza or frozen pizza from the grocery store. It can even find synonyms (words with similar meanings) and antonyms (words opposite in meaning).

The Relationship Between Words

Semantic search is a technique that uses the relationship between words to improve search results. For example, if you were searching for information on the word “horse,” you would expect to see results related to horse riding or horses in general (the word “horses” may also show up).

Semantic relationships don’t always have an exact meaning; they can be vague or abstract. Google uses this information in order to improve its understanding of what someone is looking for when they enter a query into the search bar–and then displays those results at the top of its pages.

How Google Uses Semantic Search

Google uses semantic search to improve its ability to understand the meaning of your content. For example, write an article about “the history of the Roman Empire”. Google can understand that this is not just about a history book or movie but also about an actual empire that existed in ancient Rome.

Google uses several different methods for understanding this type of information:

What Is a Latent Semantic Indexing?

Latent semantic indexing (LSI) is a search technique that uses statistical methods to determine the relationships between words in a document. It’s used by search engines to find the most relevant documents for a given query and works by analyzing the meaning of words and phrases within a document.

LSA uses an algorithm called Singular Value Decomposition (SVD), which identifies similar concepts based on their usage patterns within multiple documents. In other words, LSA groups together word with similar meanings so they can be easily found when users search for them in future queries

Use natural language in your content instead of keyword stuffing.

Semantic search is a search engine that uses natural language processing to determine the meaning of your content. This means that you should use natural language in your content instead of keyword stuffing. Semantic search engines are able to understand what users are looking for based on their query and then return results based on this understanding.

Semantic search engines also use machine learning algorithms to improve their understanding of queries over time as they receive more data about them from users’ searches and click behavior (i.e., what people click on).


Understanding the difference between keyword stuffing and the semantic search will help you build better, more effective content for your website. When you use natural language in your content (instead of keyword stuffing), Google can better understand what your page is about and rank it higher in search results because of this understanding.
