What to do, and how often.
MONTHLY
Apply updates, having backed up Test the contact form from an external address Check the site loads on a phone Confirm backups ran Check for anything obviously broken
QUARTERLY
Check prices, hours and contact details are current Review Search Console for errors Check page speed Review any content that has gone stale Test checkout, if you sell
ANNUALLY
Read the whole site as a visitor Review whether it still describes the business Remove content for things you no longer offer Review who maintains it and whether that is working Full technical review
AFTER ANY CHANGE
Check the page on a phone Check nothing else broke
THE TWO THAT MATTER MOST
Applying updates, and testing the contact form.
Updates prevent compromises. The form is where your enquiries come from, and it breaks silently.
IF YOU DO NOTHING ELSE
Set a monthly reminder for those two.
