Secondary Keywords

Secondary keywords are the highly relevant, long-tail variations and conceptually related terms that support the primary target keyword of a webpage. While a page should only have one primary keyword mapped to its title tag and H1, it can rank for hundreds of secondary keywords if the content is sufficiently deep. Injecting secondary keywords into H2 tags, image alt text, and body paragraphs is the foundation of semantic SEO. It proves to Google’s Natural Language Processing (NLP) algorithms that the page exhaustively covers the entire topic, exponentially increasing the total search volume the URL can capture.

Secondary Keywords Simplified

Secondary keywords are all the extra, related words you include in an article to support your main topic. If your main keyword is “running shoes,” your secondary keywords would be things like “best sneakers for jogging” or “lightweight running gear.” They help Google understand the full context of your page.
