Internal linking remains one of the most powerful yet cost-effective SEO strategies available to website owners. Unlike many digital marketing tactics that require significant ongoing investment, implementing an effective internal linking strategy can deliver substantial returns with relatively modest resource allocation. This article examines various internal linking methods through the lens of return on investment (ROI), helping you identify which approaches deserve priority in your SEO strategy.
Understanding the ROI Framework for Internal Linking
Before comparing methods, it’s important to establish how we’ll measure ROI for internal linking strategies. The calculation involves:
Investment factors:
