Design Scalable Programmatic SEO Systems

Designs systems for generating useful, indexable, search-driven pages at scale using templates and structured data - determining whether programmatic SEO should be done at all, scoring feasibility and risk, and designing a page system that scales quality rather than thin content. Does not implement pages unless explicitly requested.

Use this skill when evaluating whether a programmatic SEO (pSEO) initiative is worth pursuing, designing a scaled page system (templates, data model, indexation rules), or assessing risk of doorway pages/index bloat/algorithmic suppression. If the mandatory Feasibility Index scores below 50, the recommendation is to not proceed and suggest alternatives instead. Not a fit for one-off editorial content or for page implementation itself (that's a separate explicit request).

Requires calculating a mandatory Programmatic SEO Feasibility Index (0-100) before any strategy design, scoring six weighted categories: Search Pattern Validity (20 points - repeatable keyword pattern, consistent intent, sufficient demand), Unique Value per Page (25 points, the single most important factor - pages must differ meaningfully beyond swapped variables), Data Availability & Quality (20 points - data existence, accuracy, defensibility), Search Intent Alignment (15 points - full intent satisfaction with no query-page mismatch), Competitive Feasibility (10 points - beatable current rankings), and Operational Sustainability (10 points - maintainability without long-term quality debt). Each category is scored via four alignment bands (0-15% no alignment, 16-40% partial, 41-80% strong, 81-100% exemplary reinforced by a structural data source).

Feasibility bands interpret the total: 80-100 Strong Fit (well-suited), 65-79 Moderate Fit (proceed with scope limits), 50-64 High Risk (only with strong controls), and below 50 Do Not Proceed. Above 65, Phase 1 assesses business context (product, audience, funnel role, conversion goal), search opportunity (keyword pattern/variables, estimated page count, demand distribution, seasonality), and competitive landscape (who ranks now, editorial vs. programmatic nature of competitors).

Six non-negotiable core principles: page-level justification (every page must answer "why does this page deserve to exist separately?"), a data defensibility hierarchy (proprietary > product-derived > user-generated > licensed > public, with weaker data requiring stronger editorial value), URL/architecture discipline (subfolders, one page type per directory, no parameter-based duplication), intent completeness (fully satisfying informational/comparative/local/transactional intent), quality at scale (100 excellent pages beat 10,000 weak ones), and penalty/suppression avoidance (no doorway pages, auto-generated filler, near-duplicates, or no-value indexed pages).

Lists twelve programmatic SEO playbook patterns (templates, curation, conversions, comparisons, examples, locations, personas, integrations, glossary, translations, directories, profiles), usable only when supported by data, intent, and feasibility score. Phase 2 designs the page system: keyword pattern definition (structure, variables, combination estimate, demand validation), data model (required fields, sources, update frequency, missing-data handling), and template specification (mandatory sections, conditional logic, unique content mechanisms, internal linking, index/noindex criteria).

Phase 3 covers indexation and scale control - indexing only pages with demand, unique value, and complete intent match, avoiding crawl traps, and segmenting sitemaps by page type. Mandatory quality gates include a pre-index checklist (unique value, intent satisfaction, no near-duplicates, performance, correct canonicals) and kill-switch criteria (high impressions with low engagement at scale, thin content warnings, index bloat with no traffic, suppression signals) that halt indexing or trigger rollback. Required output is a structured strategy document: feasibility index with category breakdown, opportunity summary, page system design, and risks/mitigations.

Composes with seo-audit (post-launch auditing), schema-markup (structured data for templates), copywriting (non-templated sections), and analytics-tracking (performance measurement).

SEO strategists evaluating or designing programmatic SEO initiatives who need a rigorous feasibility gate and quality-at-scale design principles rather than a "just generate more pages" approach that risks thin-content penalties.

If Feasibility Index < 50: Do Not Proceed - recommend alternatives.
