Find Semantic Keywords With These Free Tools

With advancements in SEO, marketers no longer focus on targeting a single keyword throughout their web content.

Emphasis is now on building semantically relevant content around a topic. This shift aligns with Google’s consideration of semantic keywords when ranking webpages. Google uses this mechanism to provide its users with relevant results that satisfy their search intent. The best practice for improving search visibility is to find semantic keywords and target them in your web content.

Semantic keywords are keywords or phrases conceptually related to the original keyword. They provide search engine crawlers with more insight into the topic a page discusses, allowing the algorithm to rank web pages accurately.

In this post, you’ll learn about semantic keywords, why they’re important and how to find them.

What Are Semantic Keywords?

The semantic field is a set of words or phrases that belong to the same theme. Semantic keywords are words or phrases conceptually related to your primary keyword that you can use to enrich your content. They help add context to your content, making it easier for users and search engines to understand the theme of your content.

The idea behind semantic search is that when search engines look for web pages to rank, they don’t just look for matching keywords. Search engines identify the intent and meaning of a search based on every word used in a query. And then retrieve information based on the search query’s context and meaning.

What Is Semantic SEO?

Semantic SEO is the practice of producing and optimizing content to satisfy the semantic search. This is done by ensuring that a piece of content covers various relevant, related topics with depth and meaning.

Semantic content is information-rich, in-depth, and satisfies user intent. It helps search engine crawlers better understand and categorize your content. And rank it better in SERPs, improving users’ experience, and providing visibility to your website.

Semantic SEO is about understanding the relationship between keywords and topics and contextualizing them into relevant and thorough content. This differs from traditional SEO, where keyword placement is emphasized.

Websites can use semantic SEO strategies to build topical authority in their industry. This strategy can help you outrank your competitors for crucial keywords in your niche.

Semantic SEO and Google

In the past, Google’s crawlers used to scan websites for keywords to identify the page’s theme, meaning, and relevance. It looked up the frequency of keywords on a page to discover what the page was about. It checked the title tag, content body, image alt text, and headings to discover the information you intended the searchers to learn.

This resulted in marketers using “keyword stuffing” to make their content appear relevant to search engines. This means that they used the primary keyword several times on a page to rank for that keyword.

Google made significant advancements to understand and rank web content better, providing more relevant results to users. These updates enabled Google to easily understand the topic, related subtopics, and entities a piece of content covers.

Some of the advancements made include:

1. Knowledge Graph

This is a large, sophisticated knowledge base that helps Google crawlers understand the relationships between specific entities and concepts.

2. Hummingbird

Google introduced Hummingbird in 2013 to provide more relevant results to users. This update made it possible for Google to understand the meaning and context behind search queries.

The new update changed the way Google’s algorithm delivered search results. Google now processes search queries as a whole instead of interpreting words individually. The algorithm checks for context and synonyms and ensures that the search results content is comprehensive.

Now, search engines watch keyword density closely and penalize websites that engage in keyword stuffing. The algorithm prefers content that provides depth and value for the user. 

3. RankBrain

This machine learning algorithm helps Google better understand and interpret search intent to provide users with more relevant search results.

Benefits of Semantic Keywords

Using semantic keywords in your content can enhance the contextuality of your content and boost your search rankings. Semantic SEO is a crucial marketing strategy that can reap many benefits if done correctly. Some of the benefits include.

1. Helps Google Understand and Rank Your Website in SERPs

Incorporating semantic keywords in your content helps search engines understand your page better and rank it accurately. This way, Google provides users with the most relevant information about their search query.

2. Improves Your Content’s Relevance

Using semantic keywords throughout your content improves the clarity of your content and makes it more search engine-friendly. It also helps prevent “keyword stuffing.”

This increases the number of users who find your content and the time they spend on your page.

4. Presents Your Website As an Expert in Topic Areas

It also makes search engines perceive your website as an expert in a topic and a highly relevant and authoritative website in search results.
