TL;DR: Master SEO in 2026 with Topical Authority Metrics
Google's leaked metrics, Site Radius and Site Focus Score, reveal a new emphasis on topical authority in content ranking.
• Site Radius measures how close individual pages are to your site's central theme. Stay coherent for better scores.
• Site Focus Score gauges the narrowness of your site's niche. Focused themes rank higher.
This evolution favors consistent, niche-specific content, helping smaller teams outrank resource-heavy competitors. Avoid one-off content and build "topic clusters" like "semantic authority," as seen here.
Start with an audit, organize content into clusters, and interlink to improve site cohesion. Tools like Screaming Frog can help tighten focus. Build authority early to lead your niche today. Ready to get started?

The SEO world was rocked in 2026 with revelations surrounding Google’s leaked metrics: Site Radius and Site Focus Score. As a serial entrepreneur operating across deep tech and gamified education spaces, I, Violetta Bonenkamp, dissect insights like this through the lens of someone trying to tackle SEO as part of a scalable, no-code-first strategy. The key takeaway here? Google’s new emphasis on topical authority signals a radical shift in how content is evaluated and ranked.
These aren’t just abstract concepts, they’re trackable, mathematical models designed to measure content accuracy, cohesiveness, and relevance at a granular, site-wide level. The implications are crystal-clear for startups, freelancers, and solopreneurs, especially those like me who handle multiple ventures simultaneously: understanding these metrics and optimizing for them has now become non-negotiable in staying SEO-competitive. Here’s a complete breakdown, straight from a practitioner who builds systems for scaling startups without burning out.
What Are Site Radius and Site Focus Score?
Both metrics are core components of Google’s revamped topical authority evaluation as revealed by leaks in 2024 and corroborated through real-world SEO tests. They answer critical questions about your website: “Are you staying on topic?” and “How closely does your content align with your overarching theme?” While these terms may sound complicated, they can be simplified into actionable insights.
- Site Radius: Measures the distance between individual page topics and the central topic identity of your site. A low site radius signals a highly-coherent site (good!), while a high radius indicates scattered, off-topic content.
- Site Focus Score: Captures how narrowly or broadly focused your overall site theme is. A niche blog about “green smoothies” would naturally have a higher site focus score than a general lifestyle blog covering everything from travel to tech tools.
If your content drifts into unrelated territory, you undermine the authority Google attributes to your main theme. Worse, your ability to rank erodes over time.
Why Should Entrepreneurs Care About These Metrics?
Many entrepreneurs, especially solo founders or those running small, lean teams, find SEO intimidating. Trust me, I’ve been there. Whether you’re launching a new product, growing blog traffic, or aiming to create a strong personal brand, ignoring Site Focus and Radius is no longer an option. Here’s why:
- High Engagement Up For Grabs: Sites optimized for topical authority tend to attract loyal, engaged audiences. Readers view you as an expert within your niche.
- Compounding Visibility Benefits: Once Google identifies you as credible in a subject, your future content ranks faster within the same domain, it’s almost like achieving “SEO interest on your expertise.”
- Outranking Larger Competitors: Even small teams can dominate hyper-focused niches by staying cohesive in their topics, bypassing resource-heavy but unfocused competitors.
How Can Founders Master Topical Authority in 2026?
In my experience founding CADChain and Fe/male Switch, systems thinking is critical. This also holds true when tackling SEO. Treat your site like a tightly interconnected system, not a mishmash of unrelated posts. Below, I share a straightforward framework you can implement immediately:
- Conduct a Site Audit: Use tools like Screaming Frog or Ahrefs to evaluate where your content doesn’t align with your site’s overarching theme. Identify the outlier pages diluting your topical authority.
- Build Topic Clusters: Organize your content into themed clusters. For example, if your main focus is “startup education,” create content pillars like “gamification for learning” or “AI tools for entrepreneurs.” Interlink these posts for better visibility.
- Prune or Reposition Outliers: For pages not fitting your main focus, decide whether to delete, redirect, or repurpose the content. For example, I transitioned several off-topic personal blog posts into case studies for Fe/male Switch, making them educational assets instead of distractions.
- Leverage Data-Driven Iteration: Monitor metrics for success. Google Search Console’s query section now reveals data on which topics Google associates most with your domain. Use this to prioritize future topics.
Common Mistakes That Kill Topical Authority
- Poorly Defined Niche: A generic focus dilutes signals to Google. Pick a clear, specific niche like “blockchain legal compliance” instead of “blockchain solutions.”
- Ignoring Internal Linking: Without proper interlinking, search engines and readers fail to connect the dots across your content.
- Frequent “One-Off” Content: Writing disconnected blog posts breaks cohesion instead of building topical authority. Ensure every post supports your greater content strategy.
- Failing to Update or Refresh: Outdated content that doesn’t reflect the latest trends and terminology can poison your site’s focus.
What’s Next for SEO in 2026?
Simply put, foundational SEO strategies are evolving from keyword density to topic depth and user-specific satisfaction metrics. I foresee an even stronger shift toward engagement signals like time-on-site and “dwell time” over the next couple of years. In that context, fulfilling user intent won’t just win you clicks, it will secure repeat visits and brand trust. Entrepreneurs, here’s my advice: keep iterating your SEO workflows and invest in AI tools to maintain relevancy.
As Google becomes more sophisticated, so should our strategies. By focusing on topical depth and cohesion today, you’re essentially future-proofing your online presence. Remember the mantra I frequently preach: entrepreneurs who adapt early, those who analyze leaks, invest in understanding technical SEO, and implement changes, will inevitably lead their niches tomorrow.
If you’re feeling overwhelmed on where to start, consider experimenting with tools tailored to entrepreneurs and small teams. Whether it’s auditing your website, clustering content, or even automating mundane SEO tasks, make sure that staying relevant online is woven into your long-term strategy. Hear it from someone who scales companies through trial, error, and yes, strategy. Let’s become more than entrepreneurs, we’re builders of relevance and trust in 2026.
