@Siir Selecting and integrating individual keywords that are not directly categorized as primary, secondary, or tertiary can still be important for SEO, particularly if they maintain relevance to the topic of the page. These keywords can contribute significantly to driving additional traffic, especially when they tap into related interests or queries that your target audience might have.
In your example, the inclusion of terms like “innovative hair products” or “hair damages” on a page primarily about hair types can indeed be beneficial for several reasons:
Topic Depth and Breadth: By including related but not directly relevant keywords, you are broadening the scope of your content. This can make your page more informative and potentially more appealing to a wider audience. Search engines favor content that provides comprehensive coverage of a topic because it signals that the content can effectively answer user queries.
User Intent Matching: Different users may have varying intents when searching related terms. Some might be looking for types of hair but could also be interested in how to protect their hair from damage or what products to use. Addressing these related queries can capture traffic from these varied intents.
Improving Keyword Portfolio: Utilizing a diverse set of relevant keywords helps to build a more robust keyword portfolio on your site. This can enhance your site's ability to rank for a broader array of search queries.
Semantic Search Benefits: Search engines like Google use semantic search capabilities to understand the context around words in a query. Including related terms helps align your content with possible semantic interpretations and related searches, enhancing your visibility.
