What is a topic sentence?

A topic sentence is the first sentence of a paragraph that introduces its main idea. It tells the reader what the paragraph will discuss and creates a logical connection to the overall argument or narrative.

Why are topic sentences important for SEO content?

Clear topic sentences improve content scannability, helping both readers and search engines quickly understand each section's purpose. Well-structured paragraphs with strong topic sentences improve dwell time and content comprehension.
