For years, the SEO industry operated on a simple equation: more backlinks equals more rankings. Buy links, build links, earn links — whatever it took. Then something shifted. Sites started scaling without traditional link building. Programmatic SEO projects grew from zero to hundreds of thousands of monthly visits with no active outreach campaigns. And long-time SEOs began questioning whether the rules had fundamentally changed.
We sat down with David, a practitioner with years of hands-on experimentation behind him, to dig into how Google’s ranking systems actually work — not the myths, not the speculation, but what the evidence actually suggests. Here’s what we found.
How many Backlinks do I need to rank?
This is the wrong question: the question should be: what authority do I need to rank? And thats answered by
- What authority do you have
- What authority does your competitor have
Google Is a PageRank Engine Surrounded by Myths
Let’s start with the foundation. Despite years of Google communications about E-E-A-T, schema markup, content quality signals, and a hundred other ranking factors, the underlying architecture of Google Search remains deeply tied to PageRank — the link-based algorithm Larry Page and Sergey Brin built in 1998.
That doesn’t mean other signals don’t exist. It means the industry has a habit of overstating their importance. Schema markup, for example, is widely implemented as a ranking factor when it primarily serves rich results in the SERP. Implementing it won’t move your rankings. Neither will most of the technical tweaks that dominate SEO Twitter on any given week.
The mental model that actually helps: treat Google as a content-agnostic system that distributes authority through links and then uses relevance signals to decide which authoritative pages match which queries.
You Can Scale Without Backlinks — Here’s How
One of the more surprising findings from David’s experimentation: certain sites can and do grow rankings substantially without any active link building. This runs counter to the standard SEO playbook, so it’s worth understanding why it happens.
Topical Authority as a Ranking Lever
When a site comprehensively covers a narrow subject area, Google appears to assign it domain-level relevance for that topic. A site that answers 200 questions about home espresso machines is likely to rank for espresso-related queries even without external links pointing to every page — because its topical depth signals authority in a way that a broad generalist site cannot replicate.
This is the engine behind many successful programmatic SEO plays. By building deep, structured coverage of a topic space rather than random broad content, sites can establish relevance signals that partially substitute for link equity.
Internal Authority Flow
Perhaps the most underappreciated lever in modern SEO: how you distribute authority inside your own site. PageRank flows through internal links just as it flows through external ones. A site that earns 100 high-quality external links but has a flat, poorly structured internal linking architecture is wasting a significant portion of its link equity.
The reverse is also true. A site with fewer external links but a deliberate internal linking strategy — funneling authority toward priority pages, creating topical clusters, ensuring crawl depth is managed — can outperform a competitor with more links but less structural discipline.
User Behavior Signals: Real Factor or SEO Folklore?
Few topics generate more debate in SEO than whether Google uses click behavior to influence rankings. The concept of “pogo-sticking” — where a user clicks a result, quickly returns to the SERP, and clicks a different result — has been discussed as a ranking signal for over a decade.
David’s position: the evidence suggests these signals are real, even if Google denies using them directly. The mechanism may be indirect — Google’s own Chrome browser collects engagement data, and the correlation between strong engagement metrics and strong rankings is consistent enough across experiments to be meaningful.
The practical implication: optimizing for the user experience isn’t just good practice for conversion rate — it may directly affect your ability to hold rankings once you’ve earned them. Traffic flowing through a page, and users staying on that page, appears to matter more than many SEOs credit.
The Risks of AI Content at Scale
AI-generated content has made programmatic SEO cheaper and faster than ever. It’s also introduced new risks that many practitioners are underestimating.
The danger isn’t that Google can detect AI content per se. The danger is what AI content tends to produce at scale: thin coverage, repetitive structure, no genuine differentiation between near-duplicate pages. These are the characteristics that trigger site-wide quality assessments — what some practitioners refer to as Google’s “site quality score.”
A site that publishes 10,000 AI pages indiscriminately is not building topical authority. It’s building topical noise. And once a site earns a negative quality signal at the domain level, recovering from it is significantly harder than avoiding it in the first place.
Structural Decisions That Compound Over Time
Several architectural questions came up in our conversation that have outsized long-term impact:
- Subfolders vs. subdomains: For most sites, keeping a blog on a subfolder (yoursite.com/blog/) rather than a subdomain (blog.yoursite.com/) consolidates authority more effectively. Subdomains create separate authority pools.
- Near-duplicate keywords: Separate pages are often warranted even for closely related search intents, as long as the content genuinely differs. Consolidating too aggressively can mean missing keyword variants with distinct user intent.
- Entering new niches: Expanding a site into adjacent topic areas requires careful sequencing. Moving too fast, or into areas too disconnected from your established authority, can dilute topical signals rather than build them.
- Exact match domains: Still relevant in competitive niches, particularly for local search and specific query types — but not a substitute for genuine authority building.
- Forums and UGC: Forum content can contribute positively to topical authority when managed well, but dilutes it when quality is low. The volume of UGC is less important than its relevance and engagement.
Real Business Relationships Beat Link Building Campaigns
One of the clearest signals of the current SEO environment: many experienced practitioners have stopped buying backlinks entirely. Not because links don’t matter — they do — but because the risk-to-reward calculation has shifted.
Google has become significantly better at identifying link schemes, and the penalty risk for aggressive link buying is substantial. Meanwhile, links generated through genuine business relationships — partnerships, integrations, press coverage, supplier pages — are both safer and more valuable.
There’s also an interesting nuance around link value: a link from a page with high organic traffic flowing through it may deliver more ranking benefit than a link from a high-authority site where no one actually visits the linking page. The signal isn’t just who links to you — it’s whether real users are following those links.
In SEO, Authority Is a System, Not a Checklist
The SEO practitioners winning in 2026 share a common trait: they think about authority as something that flows through systems — from external links into a domain, through internal links across pages, and from user engagement back into Google’s ranking models.
Backlinks still matter. But they’re one input into a larger architecture. Sites that grow intelligently — building topical depth, structuring internal authority deliberately, earning links through real relationships, and creating pages users actually engage with — are the ones compounding over time.
The link-obsessed playbook of 2015 isn’t dead. It’s just no longer sufficient.
