siteRadius

What Is siteRadius?

Before publishing a new page, ask yourself: does this topic truly belong on my website? Pages with a high siteRadius — far from the core topic — may not only rank poorly themselves but can also weaken the topical authority of the entire domain. If a topic is important but doesn’t fit your website, a separate project or a guest post on a thematically appropriate platform is often the better choice.

siteRadius is an internal Google signal that measures the thematic distance of a single page from the overall topic of the website. Think of the website as a circle: the center is the core topic, and a page’s siteRadius describes how far it is from that center. A page about SEO audits on an SEO website has a small radius, while a cooking recipe on the same domain would have a large radius.

For content planning, siteRadius provides an important insight: pages with a large radius — content thematically far from the core — may be ranked lower or crawled less frequently. Google recognizes when content doesn’t match the topical authority of a domain. This explains why niche-specific websites often rank better for their core topics than large generalist sites.

When you align your content strategy with siteRadius, it means: expand your topics concentrically. Start with the core and work outward step by step into related areas. Use a Topical Map to plan the thematic structure. Your domain’s siteFocusScore benefits from this, and the site2vec Embedding also becomes more coherent.
