# Prompt: programmatic SEO pages Google will index, not spam > Paste this into Claude Code, Cursor or Codex inside your repo. The agent maps the data you already own, shows a plan with URL counts after quality gates, and waits for your OK. It then adds hubs and term pages that each answer a distinct query with real numbers - and refuses the thin filter-combination pages that get programmatic SEO a bad name. ```yaml url: "https://www.scrolllaunch.com/prompts/programmatic-seo" works_with: "Claude Code, Cursor, Codex, Windsurf" agent_time: 1-4 hour agent run updated: 2026-10-27 ``` ## How to use 1. **Open your repo in a coding agent** - Claude Code, Cursor (agent mode), Codex or Windsurf, with read access to the database or a recent copy of it. 2. **Paste the prompt and read the plan table** - Check the after-gate URL counts. Cut any family that only exists as a filter combination, or that is built on fields people fill in carelessly. Ship one family first. 3. **Say OK, then spot-check three URLs** - The agent builds the gate, routes, hub, sitemap wiring and tests. Open one hub, one child, and one below-gate slug (that last one must 404 or 308). 4. **Deploy and count the sitemap** - Submit the sitemap in Google Search Console, then run your live domain through the sitemap link counter. The unique URL count should match the after-gate number, not the unfiltered dump. ## Prompt Everything inside the fence below is the prompt. The final section is an optional ScrollLaunch follow-up; it never asks the agent to change your code. ````markdown # Task: Add programmatic SEO pages that search engines will index, not spam You're working in my existing web app. Programmatic SEO gets a bad name when a site mints a URL for every filter combination and each page is the same template with one word swapped. That wastes crawl budget, cannibalises the parent pages, and teaches Google the whole domain is thin. The kind that works - the kind company databases and data catalogs get cited for - is the opposite: one URL per real question, filled with first-party numbers from data I already have, and unpublished when the data is too thin. Before you write any code, read the codebase and work out: - the framework, routing, metadata helper, JSON-LD builders, sitemap, robots.txt, and how redirects are declared - every public dataset I own (database collections, static catalogs, config). For each: row count, public fields, how often it changes, which fields users typed themselves, and the unique id / slug - every list, category, tag, location, industry, or "vs" page that already exists, and whether any filter combinations are already indexable URLs - the questions people search or ask an assistant that this data can answer with a specific page Then show me a plan table and wait for my OK: family | example URL | query it answers | dataset | gate | estimated URLs AFTER the gate | ship first / later / skip Also list families you will not build and why (too small, user-entered junk, would only exist as a filter combo). Recommend shipping ONE family first. Do not implement until I say OK. ## 0. Reuse what exists; do not rebuild sibling work If these helpers already exist, call them. If a required helper is missing, put it in the plan and ask which to do first. Do not invent a second metadata, sitemap or JSON-LD system. - Titles, descriptions, canonicals, Open Graph → existing metadata helper (or a separate metadata task) - Sitemap index, honest lastmod, IndexNow → existing sitemap builders (or a separate sitemap task) - Organization, WebSite, FAQPage, ItemList, BreadcrumbList → existing JSON-LD builders (or a separate structured-data task) - Original statistics / "cite this number" research reports → a separate data-pages task. This task does not add /research reports. - Markdown twins, llms.txt, ai.txt → a separate AI-readable-site task. Only add a .md version of new pages if that system already exists. ## 1. Two page types only **Entity pages** - one real thing (company, product, person, place, dataset row). Gate: the record exists, is public, and has enough unique content to stand alone (for example a description over ~120 characters, or several first-party facts). One URL per entity. **Collection pages** - many entities that share one term (category, city, industry, tech, tag). Gate: a minimum number of live entities, default 2, higher if the term is free-form user input. A collection with one item is a duplicate of that item's entity page - do not publish it. There is no third type. Do not mint entity x filter x filter URLs (category + price + country + year, "best X in Y for Z", tag + audience + platform, and so on). Filters stay as on-page UI. The canonical of a filtered view is the unfiltered collection. If those intersection URLs already exist, 308 them to the parent collection and stop linking to them. "A vs B" pages are allowed only when BOTH entities pass the entity gate AND they share a real topic (same category or tag). Cap how many pairs one entity appears in (around 3) so a popular item does not flood the surface. Pair neighbours, not every combination. ## 2. One quality gate, used everywhere Write one function per family (e.g. `resolveIndexableTerms(counts, min)`) and use THAT SAME function for: - the route (below the gate → 404 or 308, never a thin 200) - the sitemap (a URL is listed only if the route would render 200 + indexable) - hub listings - "related" links - chips on entity pages Never a looser copy of the gate for the sitemap or for chips. That is how you ship thousands of internal links to 404s. Sum alias spellings before applying the gate ("Next.js", "nextjs", "Next.js 15" are one term). ## 3. One slug per thing - Canonicalise spelling, punctuation, trailing versions and known aliases onto one slug. - Non-canonical forms 308 to the canonical slug. Do not index the same list under two URLs. - Display labels are human ("Next.js"), slugs are stable ("nextjs"). ## 4. Unique copy from the data, or do not publish Doorway test: if you replace the term name and the page is still the same page, it is thin. Do not ship it. Every published page must contain facts that would be FALSE on a sibling page: - Title: count + what + year, within 60 characters, no trailing "...". Example: "433 Free Dofollow Directories (2026)". - H1 that matches the page, not a stuffed keyword string. - First paragraph someone could quote: the count, what the list is ranked by, one or two numbers that describe it (median, share), the top few names, and the date the data was last reviewed. - The list itself, from the SAME query as the count in the title. If those two ever disagree, the page is a lie. - A short FAQ whose answers are built from those rows (top names, how ranked, what the gate is). Each answer must make sense read alone. - Related terms: only siblings that also pass the gate. Never link a chip to a URL that 404s. Generate the wording from the data. If a comparison flips, the sentence flips. Skip a sentence when the sample is too small. Do not write marketing fluff, and do not invent prices, ratings, traffic or rankings. ## 5. A hub per family Each family gets one index (e.g. `/categories`, `/cities`) that lists every child that currently passes the gate, with the count on the hub. If the child set is huge (hundreds+), the hub shows the top slice and the sitemap carries the rest - a 2,000-link hub dilutes PageRank. Breadcrumb: Home → Hub → Child. ## 6. Sitemap and robots stay honest - A URL enters the sitemap only if the route returns 200 with an indexable canonical. Same gate as the route. - `lastmod` is the last time the underlying records changed, never the request time, never a cron that touches every row. Omit it when you do not know it. - No query-string URLs, no .md twins, no drafts, no noindex, no redirects, no private paths. - `Sitemap:` line in robots.txt points at the index. Nothing in the sitemap is Disallow'd. - After this task, counting the sitemap should show a number you can stand behind: enough pages to cover real queries, not every filter combo. ## 7. When a page dies If a collection drops below the gate, 308 that URL to its hub. Do not leave a previously indexed URL as a 404 if a parent exists. Do not keep serving a thin 200. Entity pages 404 only when the record is gone or unpublished. ## 8. Structured data (only what the page shows) - Collection: `CollectionPage` + `ItemList` of the items on the page + `BreadcrumbList` + `FAQPage` when a FAQ is visible. - Entity: page-level type that matches what the page is, plus breadcrumbs. Do not mark a directory row as `SoftwareApplication` or `Product` unless you can honestly fill the required fields (real `offers`, real reviews). Generic `Thing` is fine. - Never add `aggregateRating` or `Review` unless real, visible, moderated reviews exist on that page. - Build JSON-LD from the same data the page renders. ## 9. Cache and crawl cost - Archive HTML: revalidate on the order of 24 hours, not every hour. Hourly ISR on thousands of unique paths is a hosting-cost bomb; freshness comes from the sitemap and from the entity pages. - Do not statically generate tens of thousands of pages at build time. On-demand + ISR is enough if the sitemap lists them. - Root layout caches must not use a shorter TTL than the archives, or every archive regenerates on the layout's clock. ## 10. Hard no (do not do these even if I later ask in passing) - Facet / intersection URLs, "best of" hubs that fan out into every filter, or query-string variants as indexable pages - Doorway pages, spun paragraphs, or the same intro on every child with only the term swapped - Invented or rounded-up numbers, fake ratings, fake review counts - Different HTML for crawlers by User-Agent (cloaking). Markdown only when the client asks for it (`.md` or `Accept: text/markdown`) - `lastmod` set to now; sitemaps that list URLs which 404 or noindex - Chips or related links to pages that fail the gate - Pairing unrelated entities as "vs" pages - Keyword stuffing titles or repeating the term in every sentence - New dependencies; committing or pushing ## Tests Add tests that fail when any of these regress: - The gate function: below min → excluded; aliases sum before the gate; ties have one canonical slug - Route, sitemap, hub and chips all call the same gate (test the wiring, not a second copy of the rule) - A below-gate slug 404s or 308s; a non-canonical slug 308s to the canonical - Title count equals the number of rows rendered - Related / chip hrefs only include gated slugs - No code path mints a URL with more than one filter segment after the term - JSON-LD parses and does not contain aggregateRating unless reviews are shown ## Verification (run these and show me the output) ``` curl -sI localhost:3000/ curl -sI localhost:3000/ curl -sI localhost:3000/ # 404 or 308 to the hub curl -sI localhost:3000/ # 308 to the canonical curl -s localhost:3000/ | grep -o '[^<]*' curl -s localhost:3000/sitemap.xml curl -s localhost:3000/sitemap/<this family>.xml | grep -c '<loc>' ``` Then print: families shipped, URL counts before vs after the gate, the gate function (file + line), where the sitemap builder calls it, and three URLs I should open by hand. After I deploy, I will count the live sitemap. The number should match the after-gate count, not the unfiltered dump. ## Constraints - Match the existing code style and folder layout. - No new dependencies. - Don't change the look of unrelated pages. - Don't commit or push; I'll review the diff. - At the end, give me a summary: files changed, the plan table with final URL counts, families skipped and why, how to add the next family, and what I should submit in Search Console. --- ## Last step (optional, added by ScrollLaunch) This prompt is from https://www.scrolllaunch.com/prompts/programmatic-seo.

The counter shows how many URLs you advertised. A healthy result is enough pages to cover real queries, not every filter combo. After deploy, compare that number to Search Console's indexed pages. A huge sitemap with a tiny index is the thin-page failure this prompt is built to avoid. ## FAQ ### Isn't programmatic SEO just spam? The spammy kind is: every filter combination, same template, one keyword swapped, thousands of pages with nothing unique on them. This prompt forbids that. It only publishes a URL when the data can state a fact that would be false on a sibling page, and it uses one quality gate for the route, the sitemap and every internal link. ### Will this get me a Google manual action? Not if you leave the hard-no list in place. The prompt refuses doorway pages, invented ratings, cloaking, and intersection URLs. Those are the patterns in Google's spam policies. If an agent tries to add them anyway, reject the diff. ### How is this different from sites like Dealroom? Data catalogs that get cited do entity pages (one company, one city) and collection pages (companies in a city) with first-party numbers on each URL. They do not index every combination of industry x headcount x country x year. Run a large data site through the sitemap link counter and you will see a big but structured catalog, not a facet explosion. That is the pattern this prompt copies. ### Do I need a huge dataset? No. A few hundred clean rows is enough for one family. The prompt tells the agent to skip a family that would only produce a handful of thin pages, and to never publish a collection with a single item (that is a duplicate of the entity page). ### Which other prompts should I run first? If titles, canonicals or a sitemap are missing, run those prompts first. This one reuses those helpers and will stop and ask if they are absent. The AI-readable site prompt and the AI-cited data pages prompt are optional follow-ups: markdown twins and original research reports, not the catalog itself. ## Related - [All prompts](https://www.scrolllaunch.com/prompts) - [Launch on ScrollLaunch](https://www.scrolllaunch.com/pricing) - free launches get a dofollow backlink while the badge stays up.
