Definition
Uptime monitoring automatically checks a website at regular intervals and alerts you when it goes down, slows down or returns errors.
Uptime monitoring explained
A monitoring service requests your site, often from several locations, every few minutes. If it gets an error, a timeout or unexpected content, it sends an alert by email, SMS or chat so someone can act before customers notice or complain.
Useful checks go beyond the homepage:
- Key pages such as product, pricing, contact and checkout.
- Response time, to spot slowdowns before they become outages.
- Specific text on the page, so a blank or error page returning a 200 status is caught.
- SSL certificate expiry and domain renewal dates.
Downtime affects SEO as well as sales. Short outages are normal and unlikely to affect rankings, but repeated or long ones mean search engine crawlers keep meeting errors, which can slow crawling and, if it persists, lead to pages dropping from results. Monitoring history also helps you judge whether your hosting is good enough.
Example
Your site's host has a problem overnight and the site returns errors for hours before anyone notices. With uptime monitoring checking every few minutes, you would have been alerted within minutes and could have contacted the host straight away.
Why it matters
You can't fix downtime you don't know about. Monitoring shortens outages and protects revenue and crawling.
