Understanding LSI Keywords and Semantic Optimisation
So, what are LSI keywords and why do they matter in modern SEO?
Definition of LSI Keywords and Their Role in SEO
LSI stands for Latent Semantic Indexing, a term that's been around since the 1980s.
However, it's important to note that search engines don't actually use LSI in their algorithms.
What we're really talking about when we say "LSI keywords" are semantically related terms - words and phrases that are conceptually related to your main topic.
These related terms help search engines understand the context and depth of your content.
The Shift from LSI to Semantic Analysis in Search Algorithms
Modern search engines have moved beyond simple keyword matching to sophisticated semantic analysis.
Google's algorithms, like BERT and MUM, use natural language processing to understand the context and intent behind searches.
This shift means that focusing on a broader range of semantically related terms is more important than ever for SEO success.
According to a study by SEMrush, pages that rank for their target keywords also tend to rank for 1,000+ related keywords.
How Semantic Keywords Impact Search Engine Understanding of Content
Semantic keywords help search engines build a more comprehensive picture of your content's topic and relevance.
By including a range of related terms, you're effectively telling search engines, "This content covers the topic in depth and from multiple angles."
This can lead to better rankings for a wider range of related searches, increasing your organic visibility.
Identifying Semantic Keywords for Your Content
Now that we understand the importance of semantic keywords, let's explore how to identify them for your content.
Analysing Top-Ranking Pages for Related Terms
One of the best ways to find semantic keywords is to analyse the content that's already ranking well for your target topic.
Look at the top 5-10 results for your main keyword and note the common themes, subtopics, and related terms they use.
Tools like Ahrefs' Content Gap feature can help automate this process.
Using SEO Tools to Uncover Semantic Relationships
Several SEO tools can help you identify semantically related keywords:
- Google's Natural Language API can analyse your content and identify related entities and concepts.
- SEMrush's Topic Research tool provides a mind map of related subtopics and questions.
- MarketMuse uses AI to analyse your content against top-performing pages and suggest related terms to include.
- You can also use AI, like Claude or Perplexity to discover semantically related keywords. Simply enter your chosen keyword(s) and ask it to provide you with X number of semantically related words.
Leveraging Google's Search Features for Keyword Inspiration
Google itself can be a goldmine for semantic keyword ideas:
- "People Also Ask" boxes show related questions users are searching for.
- The "Related Searches" section at the bottom of the SERP provides closely related terms.
- Google Autocomplete suggestions can reveal common search patterns related to your topic, we like to call this the Alphabet Soup method.

Implementing Semantic Keywords in Your Content
Once you've identified your semantic keywords, it's time to incorporate them into your content effectively.
Naturally Incorporating Related Terms Throughout Your Text
The key to using semantic keywords effectively is to incorporate them naturally into your content.
Don't force them in - instead, use them as a guide to ensure you're covering your topic comprehensively.
For example, if you're writing about "coffee brewing methods", you might naturally include terms like "espresso", "French press", "pour-over", and "coffee grind size".
Balancing Primary and Semantic Keywords for Optimal Density
While it's important to include semantic keywords, don't neglect your primary keyword.
Aim for a balanced approach:
- Use your primary keyword in important places like the title, first paragraph, and at least one subheading.
- Sprinkle semantic keywords throughout the content, especially in subheadings and the body text.
- Avoid overusing any single keyword - aim for a natural, readable flow.
Using Semantic Keywords in Headers, Meta Descriptions, and Alt Text
Don't limit semantic keywords to just your main content. Incorporate them into:
- Headers and subheaders to signal the structure and topics of your content.
- Meta descriptions to improve click-through rates from search results.
- Image alt text to provide context for your visual content and improve accessibility.
Best Practices for Semantic Optimisation
Let's have a look over some best practices to take your semantic optimisation to the next level.
Creating Comprehensive, Topic-Focused Content
Search engines favour content that covers a topic comprehensively.
Aim to create in-depth content that answers all the key questions a user might have about your topic.
For example, a comprehensive guide on "coffee brewing methods" would cover different techniques, equipment needed, pros and cons of each method, and tips for perfecting each brew.
Addressing User Intent with Semantically Rich Content
Understanding and addressing user intent is crucial for semantic optimisation.
Consider the different types of search intent (informational, navigational, transactional, commercial) and create content that satisfies each.
For instance, for the keyword "best coffee makers", you might include:
- Reviews of top coffee makers (informational)
- Links to purchase recommended models (transactional)
- Comparisons of different types of coffee makers (informational)
Avoiding Keyword Stuffing and Over-Optimisation
While it's important to include semantic keywords, don't fall into the trap of keyword stuffing.
Over-optimisation can make your content sound unnatural and may even lead to penalties from search engines.
Focus on creating valuable, readable content first, and let the keywords flow naturally.
Regularly Updating Content with Fresh Semantic Keywords
SEO isn't a "set it and forget it" task. Regularly review and update your content to:
- Include new semantic keywords that have become relevant to your topic.
- Remove outdated information or keywords that are no longer relevant.
- Expand on subtopics that have gained importance since your initial publication.
According to a study by Botify, updating old content can lead to a 74% increase in organic traffic!

Measuring the Impact of Semantic Optimisation
To ensure your semantic optimisation efforts are paying off, it's crucial to track key metrics:

Tools like SEMrush's Position Tracking can help you keep tabs on a wide range of keywords.

Pay attention to the specific queries driving traffic - you might find you're ranking for semantic keywords you hadn't even specifically targeted!
Monitoring User Engagement Metrics

Monitor metrics like:
- Time on page
- Bounce rate
- Pages per session
Improvements in these metrics can indicate that your semantic optimisation is resonating with users.
