NightroBot

Ad landing pages

The pages a business's Google Ads send people to: every 20 minutes, and every address in its ads once a day

Pages in an ad change

Before Nightro sends the change to Google Ads, each with one made-up address beside it

Website Doctor

The business's own site, when a person starts a check: up to 40 pages and a sample of links and images, 6 checks a day at most

Speed test

Up to 3 page loads in Chrome per Website Doctor check, as a phone and a laptop, with the files each page loads

Other

OpenStreetMap place lookups, one a second at most, and Google's connection check page

Only for businesses that run their Google Ads with Nightro.

Website Doctor crawl

At most 4 requests at a time; a 150 ms pause after each page or link checked

Speed test

One page load at a time, beside the crawl

Ad landing pages

Every 20 minutes; a page that fails, once more

robots.txt

Before the first request to a site, then every 60 minutes

User-agent: NightroBot

Followed by every request

User-agent: *

Followed by the Website Doctor's crawl. Other checks follow only the NightroBot group, as Google's ad robot follows only its own.

Block NightroBot

User-agent: NightroBot
Disallow: /

Nightro then can't check those pages, and sends Google Ads no change that points to them.
