What is horizontal intertextuality?

Horizontal intertextuality refers to the relationship between texts of the same type or genre, where ideas, themes, or structures connect and influence each other across similar content. Just like comparing product reviews or guides within the same category, understanding horizontal intertextuality helps readers see patterns and shared meanings. In the same way, when exploring cooking tools, multiple discussions about a Gas Toaster Grill across blogs or articles help build a clear picture of its features, benefits, and everyday use through related, comparable texts.
