Launching ten sites in one week without mistakes
Launching ten sites in a week fails for a different reason than launching one. A single launch fails on things you forgot. A batch fails on things you remembered too well: one value copied from the first site into the other nine, silently, because the template carried it. The fix is not more care per site. It is splitting the work into what is deliberately reused and what must be regenerated, then staggering the batch so a wrong value shows up after site one instead of after site ten.
Decide up front what travels and what never travels
Write this list before you touch the first site. Anything not on the "reuse" side is generated fresh, per site, with no copy-paste.
| Item | Batch treatment | What a silent copy causes |
|---|---|---|
| Page template, theme files, build config | Reuse verbatim | Nothing. This is the point of a batch. |
Canonical host line, sitemap URL, robots.txt host reference | Reuse the file, rewrite the value | Nine sites declaring themselves as site one |
| Admin username and password | Never reuse | One exposed credential opens the whole batch |
| Database name, user, password | Never reuse | Restores and rollbacks stop being isolated |
| Analytics and Search Console property | Never reuse | Nine sites report nothing, or all ten pile into one property |
| Contact form recipient and reply-to | Per site | Leads arrive attributed to the wrong project |
| IP or account assignment | From your map, not from the last site | The separation you paid for quietly collapses |
The last row is the expensive one. If you bought separated addressing to keep projects from sharing a footprint, a template that carries the first site's account or address assignment undoes that on nine sites at once, and nothing visibly breaks. Work from a written site-to-address map instead of from memory, as covered in network planning.
Stagger the batch: 1, then 3, then 6
Never run ten sites in parallel through the same stage. Run one site end to end, stop, verify it from the outside, and only then open the next group.
The arithmetic is the whole argument. A wrong canonical host costs a few minutes to correct on one site. Caught after ten, it costs ten corrections, ten re-verifications, and whatever a search engine already recorded in between. The pilot is not slow. It is the cheapest place to be wrong.
Track state, not tasks
Keep one sheet, one row per site, one column per stage: account created, files deployed, certificate live, canonical set, analytics attached, domain pointed, verified. Two allowed values only: blank or verified. Ban the middle value. "In progress" is where half-finished sites hide, and in a batch of ten you will not remember which half.
Verification means checking from outside your own machine, not from the tab you just had open. Fetch the live URL, read the canonical it returns, confirm the certificate answers on the real hostname, and confirm the analytics property receiving the hit is the one named for that site.
The check that catches the silent repeat
Once the batch is complete, do one comparison pass across all ten instead of ten checks in isolation. Put the ten values side by side for each field that should be unique:
- Canonical URL returned by the live homepage
- Sitemap location and the first URL inside it
- Contact form recipient address
- Analytics property identifier
- Database user name
- Assigned account and address
Any field where two rows match is a copied setting. This pass takes a few minutes and finds the exact class of error that per-site checking misses, because per-site checking asks "is this value present" and never asks "is this value this site's value". Other sequencing playbooks in launch playbooks cover the single-site order of operations that each group in the batch follows.
