Most Shopify store owners are reactive. They find out something is broken when a customer tweets about it, when their sales suddenly drop, or when Google stops sending traffic. By then the damage is done.
The stores that consistently grow are the ones that catch problems early. Here are the six things you should check every single month — before your customers notice anything.
Run your store URL through Google PageSpeed Insights and check your mobile score. Anything under 50 is poor. Focus on your LCP — if it is over 4 seconds you are losing mobile visitors before they see your products. Mobile traffic is now over 70% of ecommerce — this is your most important metric.
Go to your own store right now. Add a product to cart. Go through checkout. Did everything work? Did the cart load? Did the checkout button appear? Shopify app updates and theme changes frequently break checkout flows silently. Test it yourself every month — or automate it with a tool that does it daily.
Your SSL certificate — the padlock in the browser — expires. Most renew automatically but some do not. A lapsed SSL certificate means browsers show a "Not Secure" warning to every visitor. Conversion rates drop to near zero. Check your certificate expiry date and make sure auto-renewal is enabled.
Every time you delete a product, rename a collection, or restructure your navigation — you create broken links. Customers hit 404 pages and leave. Google crawls broken links and reduces your ranking. Run a broken link check monthly and fix anything returning a 404 — especially in your navigation and homepage.
Check that your review app is still displaying correctly on product pages. Confirm your return policy is linked from the footer. Make sure your contact page is accessible. These three signals — reviews, returns, contact — are what customers look for before they buy. If any of them is missing or broken your conversion rate suffers silently.
Theme updates and app installations regularly overwrite your SEO settings without warning. Check your homepage and top product pages have meta titles under 60 characters, meta descriptions between 150-160 characters, and a single clear H1 tag. These take 5 minutes to audit and directly affect how Google ranks your store.
The honest truth is that most store owners do not run these checks every month. They mean to — but between managing inventory, running ads, handling customer service, and everything else — the monthly audit gets skipped.
And that is exactly when things break quietly in the background. A checkout button stops working on a specific browser. An SSL certificate expires. A review app stops loading after a theme update. Nobody notices for weeks.
Cartfy scans your store daily across all six of these categories and alerts you the moment something changes. Most issues are caught and fixed before a single customer notices.
