Homepage conversions dropped after a change? Check these

Key takeaways

If homepage conversions dropped after a change, check four things in order: tracking (is the key event still firing?), routes (do the form, phone link and booking still work on phones?), speed (did the change slow the first screen?) and message (did the headline, proof or main button move?). Most drops after a change are broken tracking or broken routes, not the new design.

• 1. Tracking: is the key event still firing?
• 2. Routes: do form, phone and booking work on phones?
• 3. Speed: did the first screen get slower?
• 4. Message: did the headline, proof or button move?

Why do conversions drop after a homepage change?

Conversions drop after a change for technical reasons more often than design reasons: a tracking tag lost in the update, a form plugin that stopped sending, a button that now sits behind a chat bubble on iPhones. Design reasons follow: a headline that became vaguer, proof that moved down or a main button that lost its prominence.

• Why your homepage is not converting visitors into customers
• Conversion rate dropped suddenly? What to check first

Step 1: is the tracking still working?

Check GA4's realtime or DebugView while you submit a test enquiry and tap the phone number. If the events do not appear, the drop may be in the data, not the business. Compare with your inbox: if real enquiries are steady, fix tracking before anything else.

• Track homepage button clicks in GA4
• Clean homepage data: bots, staff visits and consent gaps

Step 2: do the enquiry routes still work?

Submit the form and check the email arrives, including in spam. Tap the phone link on a phone. Complete a booking. Do it on an iPhone and an Android. Many drops are a route that fails silently on one browser after an update.

• Is your homepage broken on someone else's phone?
• Contact form emails going to spam? Fix it before leads go

Step 3: did the first screen get slower?

Run PageSpeed Insights on mobile and compare Largest Contentful Paint with before the change, if you saved it. New hero images, video, fonts or scripts are common causes. Even a second or two can matter on phones.

Step 4: did the message or action move?

Put screenshots of the old and new homepage side by side on a phone. Did the headline become less specific? Did the trust line or reviews move down? Is the main button smaller, renamed or competing with a new one? Restore the element that changed most, then measure again.

• Change one thing at a time: a homepage change log
• One primary call to action on your homepage

When is the drop not about the homepage?

Check seasonality, traffic volume, Google Business Profile changes and any campaign that ended. Compare with the same period last year and look at whether homepage sessions fell. A drop in traffic will lower enquiries even if the page converts just as well.

• Homepage conversion by traffic source

What does this look like in practice?

A pattern we see: enquiries fall by half after a 'small refresh', and the owner wants to roll back the whole design. The real cause is a form plugin update that stopped emails reaching the inbox. Fixing it takes an hour and the new design stays.

Conversion drop checklist

• Test that key events still fire in GA4.
• Submit the form and check the email arrives.
• Tap the phone link and complete a booking on two phones.
• Compare mobile LCP with before the change.
• Compare old and new screenshots on a phone.
• Rule out season, traffic and campaigns.

• Clean homepage data: bots, staff visits and consent gaps
• Wrong visitors reaching your homepage? Check traffic first

Next step

Before changing anything back, submit a test enquiry through your homepage on your phone and check it arrives. That one test rules out the most common cause.
