Content Optimization: Keyword Density & LSI Keywords

Content optimization is about crafting website content that's both engaging for readers and easily understandable for search engines. Two key aspects of this are keyword density and LSI keywords.


1. Keyword Density:

Keyword density refers to the percentage of times a specific keyword or phrase appears on a webpage compared to the total number of words. Historically, high keyword density was seen as a way to rank well, leading to practices like keyword stuffing. Modern SEO discourages this.

Why it matters (but shouldn't be abused): A reasonable keyword density signals to search engines what the page is about.


Example: If your target keyword is "dog training," a good keyword density might be around 1-3%. This means "dog training" would appear 1-3 times for every 100 words.


Don't stuff!: Overdoing it (e.g., "dog training dog training professional dog training") makes your content unreadable and can get you penalized. Focus on natural integration.


2. LSI Keywords (Latent Semantic Indexing):

LSI keywords are words and phrases that are semantically related to your primary keyword. They provide context and help search engines understand the topic of your page more thoroughly. Think of them as synonyms, related concepts, and supporting terms.

Why they matter: They demonstrate that you're covering a topic comprehensively and naturally. Search engines use them to confirm the relevance of your content.


Example: If your primary keyword is "dog training," LSI keywords might include:

"puppy obedience"

"crate training"

"positive reinforcement"

"dog behavior"

"leash training"

"dog commands"


How to use them: Incorporate LSI keywords naturally within your content. They should flow with the writing and add value to the reader's understanding of the topic.


In Summary:

Optimizing content with a balanced keyword density and relevant LSI keywords helps you create content that is both search engine-friendly and reader-friendly. The goal is to inform, engage, and provide value to your audience, while also signalling relevance to search engines. Focus on creating natural, high-quality content above all else.
