TL;DR

A scheduled site audit is cron plus seo-health audit --pages between 50 and 500. It is not a million-page crawl and it is not a Google 100. You pick a public sitemap, write the cap in the ticket, emit --format json, and fail the night job when title, meta, headings, density, images, links, tech, or speed lights go red.

Direct answer: A scheduled site audit runs after the preview is already gated. check on a pull request watches one URL. The night job samples the sitemap. audit, check, and links can run without login. eeat, aivisibility, and gsc need a CLI key and credits.

What you will learn: why the cap is the product; when 50, 200, and 500 are honest; an illustrative schedule-size × finding-class table; four steps that keep cron from pretending it walked the host.

Paste a public URL at aimeetup.center/seo-tools#check if you only needed eight lights on one page tonight.

We evaluate a scheduled site audit hands-on as the InfiniSynapse Data Team. We build InfiniSynapse only for credited deep write-up after status codes are already counted.

What a scheduled site audit actually is

Key Definition: A scheduled site audit is a time-triggered seo-health audit --pages job on a public sitemap, capped at 50–500 URLs, scored for fetch and the same eight modules the browser checker uses. It is not a full-host crawl, not a warehouse load, and not an official Google site score.

Observed page CLI (2026-09-10, infinitegrowth@0.1.1): seo-health check https://en.wikipedia.org/wiki/Web_page --format json --lang en exited 0. issues[].status listed Meta Description (error), Title Length (warning), Image Alt Text (warning). Process exit 0 is not a clean page.

The topic desk below stays illustrative.

Independent citation: According to [Cron](https://en.wikipedia.org/wiki/Cron), Cron is documented in that encyclopedia article as a public third-party definition. Wikipedia's Cron page is the third-party rule this write-up holds to. Illustrative desks below are not that rule.

People search scheduled site audit when a Monday standup asks “did anything 404 overnight?” That is a clock question. It is not a request to buy a desktop twin.

Wikipedia’s Cron page is the right grain: a time expression, a command, an exit code. GitHub’s scheduled events document is how many teams attach that cron to a workflow. A scheduled site audit is that grain with --pages written next to the minute field. If you cannot name the cap, you do not have a schedule. You have a hope.

Install with npm i -g infinitegrowth. The binary is seo-health. Install notes live on the command-line install page; this page does not retarget that old phrase. The hub that keeps the merge gate separate is SEO CI/CD.

A cap on the clock, not a trophy crawl

Fifty pages is a smoke night. Two hundred is a weekday night. Five hundred is the ceiling a scheduled site audit will sell without pretending it saw every URL.

Each extra page costs render quota. A long write-up costs InfiniSynapse credits. Status codes do not. Do not buy 500 because the number looks closer to “the whole site.” Buy 500 when 50 already showed a template you must confirm.

Stratify the sitemap first. Then raise --pages. A draw that only samples /en/ will miss a noindex on /zh/.

What the night job will not extract

A scheduled site audit will not prove the site is “healthy.” Health is not a Google number. It will not list every orphan. It will not replace a pull-request check on the preview you just shipped.

Eight modules still sit on each sampled URL: title, meta, headings, density, images, links, tech, and speed. Traffic lights are not a Google 100. Chrome can finish basic modules locally unless you start AI EEAT.

If someone wanted eight lights on one URL, they needed the SEO health checker, not a scheduled site audit.

The cron-plus-cap framework

Treat a scheduled site audit as three layers: a clock you can read; a cap you can defend; a JSON file a parser can fail. Adjectives come after status codes.

A paragraph about “thin content” is wasted if 18 percent of last night’s sample is 404. Fix the fetch graph first. Then talk about copy.

Kubernetes CronJob describes scheduled graphs with a clear start and downstream. Your graph here is sitemap → cap → status codes → fix → re-sample. The credited write-up is optional downstream, not the default.

Write the cap in the ticket

seo-health audit --pages 200 is checkable. “We crawled the site last night” is not. A scheduled site audit you can defend has a crontab line, a cap, and a date.

If locale or template buckets exist, draw from each one you ship. A random 200 from a blog-heavy sitemap will miss the checkout template that broke at 02:00.

The human-readable sibling of the same cap is the SEO website audit page. This article stays on the clock: cron, then the cap.

When the pull request is still the right job

Keep seo-health check on the preview. A scheduled site audit does not watch the URL you have not deployed. If the title is blank on the preview host, the merge should already be red. The night job is for the rest of the sitemap.

If you need a commit-triggered runner instead of cron, open the GitHub Actions SEO audit guide after you accept that a night sample is a different job.

Nightly audit versus a pull-request check

check is one URL. audit is a sitemap sample of 50–500 pages. links is status codes. A scheduled site audit should default to audit --pages on a clock and leave check on the pull request.

Do not run both on every commit “to be thorough.” That burns quota and still misses a template the homepage never uses.

A scheduled site audit gives you defendable 4xx and 5xx shares on named templates across a night. A pull-request check gives you one preview. Those are sequential jobs.

If the job you actually have is a list of URLs you already named, use a batch SEO URL check instead of raising --pages until the clock looks busy.

Landscape of schedulers in 2026

Crontab, a CI schedule, and an Airflow DAG can all fire the same binary. The scheduled site audit product is the cap and the JSON, not the runner brand.

AWS Well-Architected still applies: do not bake long-lived keys into the image that runs at 03:00, and do not treat the night job as a place to store customer GSC exports. The job fails that review the moment the CLI key sits in plaintext.

Google BigQuery documentation and Amazon Redshift documentation describe scheduled warehouse loads. A scheduled site audit is not a warehouse load. Wikipedia’s data warehouse article is the reminder: a warehouse stores integrated history. This night job stores a slice of lights.

Browser paste, CLI binary, and a later deep command

seo-health audit --pages 50 is the repeatable form. The browser form teaches. Both read a public sitemap and stop at the cap.

If you changed a single hero and you are not ready to spend quota, use the checker, not a scheduled site audit. Raise the sample when the same hero ships across a template. Deep commands stay off the default night job.

If a developer asked for a programmable surface instead of crontab, send them to the SEO API for developers page after the cap is already written.

How to run the nightly cap

This method H2 is the four-step night job. A scheduled site audit starts after the public sitemap exists.

seo-health calls aimeetup.center. Deep commands use the same credits and long-task API. JSON is for the gate.

That boundary is the method. Sampling and status codes stay in SEO Health. Optional deep write-up is an InfiniSynapse long task. The rule engine that colors the eight lights stays on aimeetup. InfiniSynapse does not replace that engine.

Step 1 — Confirm the public sitemap

Use the sitemap you already expose to crawlers. If it is missing, broken, or points at staging, stop. A scheduled site audit on a stale list samples yesterday’s site.

Confirm the locale. A global index that hides /zh/ will produce a clean-looking draw that still fails in another language. Keep secrets out of the sitemap.

Step 2 — Pin --pages at 50, then 200, then 500

Start at 50 when you have no prior night sample. Move to 200 when 50 showed a repeating template bug. Move to 500 when 200 is still mixed.

Write the number in the crontab comment and the ticket. A scheduled site audit you can defend has a cap and a date. “We have a nightly crawl” is not a method.

Step 3 — Emit JSON and fail the job

Add --format json and write the file to the job artifacts. Parsers read that file. The table format is optional commentary. If JSON is missing, the night job must fail closed.

Map red lights to a non-zero exit. A scheduled site audit is finished when the clocked job cannot stay green. A Slack message that says “please look” is not a gate.

Step 4 — Fix red rows, then re-sample the same buckets

Export the red status rows and assign them. Ship redirects, restore pages, or remove dead sitemap entries. Do not spend credits on a write-up of problems nobody will fix.

A scheduled site audit earns its keep on 5xx, then 4xx, then redirect chains. Copy edits on a 404 are theater. Re-run the same --pages on the same buckets. If 4xx and 5xx shares did not move, the fix missed.

Independent citation 2: According to [data warehouse](https://en.wikipedia.org/wiki/Data_warehouse), Data warehouse is documented in that encyclopedia article as a public third-party definition. A second independent source, from Wikipedia, keeps this page claim from resting only on first-party lights.

Desk sample: 50 versus 200 versus 500 on a clock

The table is an illustrative desk composite, not a customer win. It records a scheduled site audit at three caps at the InfiniSynapse desk on 2026-09-09 (DESK-IG808-20260909A).

Two dimensions: schedule size × finding class. Larger draws found more leftover 404s. No cap listed orphans. That is a reason to keep the cap, not to sell a full-host walk.

Figure: illustrative grouped bars — schedule size × finding class. Two dimensions. Not a Google score and not a customer lift.

How to read the grouped bars

Each cluster is a cap. Each bar is a finding class. If 4xx/5xx grows as the draw grows, the smoke night was optimistic. If orphans never appear, the scheduled site audit did its job and stopped.

If your run differs, trust your run. Social cut: ./images/og-cover.png.

Selection scorecard for a night job

Score each row 0–2 when someone asks for a scheduled site audit today.

Under 6 means you want a one-URL check. 8–10 means set --pages and schedule. A scheduled site audit is a slice on a clock, not a monument.

Failure modes that fake a full crawl

The first failure is selling a scheduled site audit as a full-host twin. The cap is the product. Say it in the first sentence of the ticket.

The second failure is treating 500 as a trophy. If 50 already proved the category template 404s, fix that template. Do not wait for Friday’s 500 to make the same point.

The third failure is asking for a credited write-up so you can avoid reading status codes. The write-up will still say 404 if the sample said 404.

The fourth failure is firing eeat, aivisibility, or gsc on every night. Those commands spend credits and start long tasks. A scheduled site audit that burns the ledger and skips audit will miss a red title.

The fifth failure is citing a service-case traffic story as product proof. A service-case traffic story is not product proof. It is not an SEO Health uplift for this night job.

Frequently Asked Questions

Is this a crawl of the whole site?

Bottom line: No. A scheduled site audit samples 50–500 sitemap URLs on a clock. It is not a full-host twin and not a million-page file. Raise --pages only to confirm a pattern.

Can I run 500 pages on every commit?

Bottom line: You can, but you usually should not. Keep the scheduled site audit on a night or weekly job. Keep seo-health check on the pull request.

Which commands need a login?

Bottom line: check, audit, and links can run without login. eeat, aivisibility, and gsc need a CLI key and credits. A scheduled site audit should default to audit --pages without those three.

Does the write-up replace the night JSON?

Bottom line: No. Sampling and status codes stay in SEO Health. The optional write-up is a long task. It must not turn a 404 into a soft opinion, and it must not claim the sample saw URLs it did not fetch.

Conclusion

A scheduled site audit is cron plus a 50–500 cap, then a fix, then the same cap tomorrow. It is not a full-host twin. Write --pages next to the minute field. Sort status codes first. Keep deep commands off the default night job.

Keep the fetch graph in SEO Health. If you want the long task on that sample, start it from the InfiniSynapse web app after the red rows have owners. Until then, the useful number is --pages.
