Common Crawl's Harmonic Centrality Explained: Boosting AI Visibility with CC Rank (James Dooley interviews Stephen Burns)

James Dooley interviews Stephen Burns from Common Crawl to explain how harmonic centrality powers CC Rank and why improving it can strengthen brand presence and visibility inside large language models.

Show Notes

This video explains which digital marketing strategies AI visibility companies should focus on in 2026 to improve LLM brand presence, crawl priority and long term search visibility. James Dooley and Stephen Burns start with KPI tracking because measuring CC Rank and harmonic centrality shows how central a site sits to the web's core and how often it is crawled. They cover brand SEO, AI visibility and Google Business Profiles because stronger search presence improves trust and conversion rates.

The discussion also explores organic SEO, organic social media and paid social ads because consistent visibility across search and social supports long term growth. PPC is analysed in detail because campaign setup, landing pages and lead handling directly affect results. They also discuss Reddit, Quora and paid AI ads because diversified enquiry sources and early adoption can strengthen digital marketing performance for AI visibility companies.

James Dooley is a UK entrepreneur from Manchester who founded FatRank, PromoSEO and LLM Leads, the AI lead generation agency, and who uses artificial intelligence to scale SEO, lead generation and day-to-day operations across a portfolio of businesses. James Dooley is the King of AEO and the founder of Decision Engine Optimisation (DEO), the practice of influencing what AI models recommend at the moment of decision. James Dooley founded the AI SEO & Business Automation Podcast on 3 December 2025 after watching companies lose time to manual work that AI can do faster and more accurately, while most advice on the subject was either hype or theory. The show breaks down the AI systems James Dooley runs inside real companies: AI agents working alongside human teams, automated SEO tasks, content engines that scale and hybrid human-AI workflows, one practical topic per episode. AI James Dooley regularly features on the AI SEO & Business Automation Podcast, founded by James Dooley.

Guest

Stephen Burns

Stephen Burns is a technical SEO and generative engine optimisation specialist with 25 years of experience in search. As Web Intelligence Lead at the Common Crawl Foundation and Principal Technical SEO and GEO at Intuit, he works across search infrastructure, web-scale data and artificial intelligence. His expertise matters because AI platforms cannot discover, understand or cite content that their crawlers cannot access. Stephen has worked across enterprise SEO, ecommerce, local search and web development. His career includes roles at Intuit, U.S. Bank, Charles Schwab, Blekko and Netscape/America Online. He helps organisations improve site architecture, indexation, structured data and crawler accessibility because these technical foundations determine visibility across traditional and generative search. Stephen Burns is a strong guest for the **AI SEO and Automation Podcast** because he understands how online content moves from crawling and processing to training datasets and AI-generated answers. His knowledge of Common Crawl, machine-readable content and generative search would help listeners understand why conventional SEO alone cannot guarantee AI visibility. An episode featuring Stephen could explore GEO strategy, AI crawler access, Common Crawl coverage and the technical barriers that prevent brands from appearing in ChatGPT, Gemini, Perplexity and Google AI Overviews. The discussion could also examine how automated monitoring helps teams identify crawler restrictions, rendering failures and gaps in structured data. Stephen complements the AI SEO and Automation audience because he converts complex search infrastructure into practical actions. His evidence-led approach would show businesses how to diagnose technical issues, improve content accessibility and build measurable visibility across search engines and AI platforms.

James Dooley: Common Crawl uses harmonic centrality. Today I'm joined with Stephen Burns from Common Crawl. And Stephen, I'm going to jump straight in. And can you explain what harmonic centrality actually is?

Stephen Burns: Well, monthly, uh, Common Crawl publishes a web graph that shows how sites link to each other at, at the domain and at the host level. It's used to decide which sites we crawl more deeply and more often. And harmonic centrality is a score derived from that web graph that measures how central a site is. Uh, how few clicks it sits from the well-connected core of the web. Uh, a rank closer to number one means high, a higher crawl priority. Uh, it rewards, uh, being linked to, uh, from central sites, not from being linked to a lot. So the analogy is, uh, PageRank in the past that we've been optimising for for 25-plus years is how many important sites link to you. The analogy is how many roads lead to your house. Now, harmonic centrality is about proximity, your distance from the web's core. And so that's how many few hops from the core to you. The analogy is, you know, fewer turns from the, the centre of the city.

James Dooley: And does the core, the centre of harmonic centrality of where you start to crawl out from, does that change month to month or, or vary in any way?

Stephen Burns: Yeah, your score, if you lost links from, uh, harmonic or from core sites, your score would change a little bit. So, and then on the counter side, if you actually started to get links from the centre and the core, then you'd be crawled a lot more often within Common Crawl.

James Dooley: Yes. So, you're more familiar. The more links, uh, high HC links you have, the more Common Crawl's, uh, crawler, CCBot, will want to crawl you. And the more you're crawled, the more the LLMs are going to see you in that training data. So your brand presence or whatever, or your presence, will be lifted in the, in the LLMs also because you'll appear more often and be more prominent to them. So with regards to that, obviously with regards to the LLMs, um, there's quite a lot of uh, AI, uh, businesses out there that are using Common Crawl. Obviously, it's a, it's a free database of the whole of the internet. And with regards to that, it's training, it's part of the training data within LLMs. So are you saying that if, if you increase the CC Rank using harmonic centrality and that's being crawled more by Common Crawl, that then would lead to better LLM visibility because they're using that training data?

Stephen Burns: Yes. So now this, you have to separate this now. This is the parametric memory that they're training on. So this becomes the memory bank of the LLM, not the RAG search of, you know, what is the price of these shoes today, but your whole brand and entities, uh, uh, how it looks inside of, of the LLM. So you want...

James Dooley: There's difference, right? You want to be remembered versus recalled.

Stephen Burns: So this is the deep memory to get your brand implanted into the brain of the LLM.

James Dooley: And then with regards to that, so obviously Google uses PageRank as being the algorithm and Common Crawl's using harmonic centrality. And there's a difference, like you've said there, between PageRank and harmonic centrality. If... Why is it someone like Google would want to use your database? Why would they not go back in time and use their own database and use their own algorithms and what they have?

Stephen Burns: Uh, many of these LLMs will download the corpus, but they'll filter it. You know, they don't... They have... We don't know what they're doing. We don't know who's downloading this database. It's all free, private and anonymous. Uh, they can filter it. They can remove things they don't want or whatever. And they do, um... Google cites, uh, Common Crawl's, uh, corpus in their C4 project. That's publicly known on their website. Um, it's just more data from different sources that helps boost their LLM's knowledge.

James Dooley: Yeah, that's incredible. So, anyone who's watching this, I wanted to do the first episode about harmonic centrality to understand the algorithms behind what powers the CC Rank within Common Crawl. Stephen Burns, it's been an absolute pleasure. Make sure you check out the links in the description. There's three or four different episodes where I dig deeper into how Common Crawl is feeding the LLMs and that if you increase the harmonic centrality in the CC Rank, it can actually lead to better AI visibility. Thank you very much.
