Programmatic SEO with LLMs (Real Playbook)
AI is changing SEO, but not in the ways most people think.
Setting the Context
Most operators I've seen fail here get stuck because they underestimate how much backlink competition matters. Content quality alone hasn't been enough to rank since 2019.
To answer this properly, we need to look at real data, not opinions. Fortunately, the Common Crawl project publishes monthly snapshots of the public web graph, giving us access to 4.34 billion backlink edges. This is the same data agencies pay $99+/month to access through Ahrefs.
The Data Says...
Real winners in this space have one thing in common: they use paid or free tools consistently to understand their competitive landscape before making moves.
Analyzing 262 million hosts across the Common Crawl 2026 dataset, several patterns emerge. Domains with 50+ referring domains show measurably better SERP performance than those with fewer than 10. Domains with 500+ referring domains often outperform brand-new sites in the same niche within 90 days of acquisition.
What This Means for You
If you're building a site from scratch, you have two paths:
- Slow path — Build backlinks organically over 12-24 months
- Fast path — Acquire an expired domain with existing authority
Neither is wrong, but they have very different economics. Tools like backlink data api help you evaluate the fast path without spending $99/month on Ahrefs.
Real Example from My Notes
The example that changed my thinking on this was a client project last quarter. They were in a competitive niche, and their previous SEO agency had given up.
Last month I was researching developer platforms for a client, and I found an expired domain with 12-20 referring domains available for $10 registration. Within 90 days, we the site broke into the top 10 for its main target keyword. That's a return no organic strategy can match at that speed.
Making a Decision
The decision framework I use:
| If you have... | Then... |
|---|---|
| Time, no budget | Build organically, use free tools |
| Budget, need speed | Acquire expired domains |
| Both | Do both in parallel |
Where to Start
For research, I use the daily drops list from seo-backlinks.net — it's free, updated every morning, and shows real referring domain counts. If you graduate to paid tier ($9-29/mo depending on country), you unlock bulk lookups and API access.
Closing
The main takeaway: you don't need to spend $500/month on tools to win. You need to spend the right time on the right work, informed by real data. Free and $9-29/mo tools cover 80% of what most operators need.
