Programmatic SEO

Builds on SEO Foundations@markdowners/seo-foundations — programmatic (template-generated) pages must clear a higher bar for genuine uniqueness, precisely because they're easy to generate in bulk without it.

Uniqueness is the whole game

• Every programmatically generated page must have genuinely unique, useful content relative to every other page in the set — not just a unique URL and a swapped headline over otherwise identical boilerplate. A template that only changes one variable (a city name, a product name) in a sea of shared filler text produces near-duplicate content that search engines actively filter or penalize at scale.
• Before generating thousands of pages from a template, verify each page independently would be worth linking to and worth a user's time — if the honest answer for most of the set is "not really," the template needs more real, page-specific data before scaling, not after.

Data quality

• Every generated page needs real, verifiable underlying data (actual inventory, actual pricing, actual location details) — never generate pages for combinations that don't correspond to something real just to increase page count; empty or fabricated-data pages are exactly the "thin content" search engines are designed to demote.
• Handle the "no data for this combination" case by not generating the page at all (404/410), rather than generating a page with empty sections — a page with nothing real to say should not exist.

Scale and crawl budget

• Prioritize the sitemap and internal linking toward the highest-value pages in the set first — search engines allocate a finite crawl budget per site, and a sitemap of hundreds of thousands of near-identical URLs dilutes attention away from the pages that matter most.
• Add pagination or filtering carefully with canonical tags pointing at the primary variant, so parameter combinations don't multiply the effectively-indexed duplicate surface.

Templates

• Vary sentence structure and section composition across the template's output, not just the substituted variables — pure mail-merge text (identical sentence shape, different noun) reads as machine-generated to both users and increasingly sophisticated content-quality algorithms.
• Include genuinely differentiated sections per page where the underlying data supports it (reviews, real specifications, related-item data) rather than only a title/description swap.

Monitoring

• Track indexation rate (pages generated vs. pages actually indexed) as a health metric — a large and growing gap between the two is an early signal that the template's content quality bar is too low, well before it shows up as a ranking penalty.
