10 Wedding Website Mistakes to Avoid

I've seen a lot of wedding websites, both as a guest and through helping couples build theirs. The same mistakes come up over and over. Some are technical, some are design, some are just oversights. All of them are avoidable once you know what to watch for.

Here's the list, in rough order of how often they happen and how much they affect your guests.

1. Hiding the RSVP button

This is the biggest one. Your guests are on the site to do one thing: RSVP. If the button isn't obvious within three seconds of loading the page, you've lost them.

Bad signs:

• RSVP is buried in a dropdown menu
• The button label is something cute like "Our Favour" instead of the word "RSVP"
• The button colour blends into the background
• Guests have to scroll past the whole story section to find it

Put the RSVP button in the main navigation and as a prominent call-to-action in the hero area. Use the word "RSVP." Don't make your guests hunt.

2. The site doesn't work on phones

Most wedding website traffic comes from mobile devices. If the layout breaks on a phone (text overlapping photos, buttons too small to tap, navigation that doesn't collapse properly), you're losing the majority of your visitors.

Test on a real phone, not just the desktop preview. Tap every button. Fill out the RSVP form. If anything feels off, fix it. For more on why this matters, why your wedding website must work on mobile covers the full picture.

3. Old information that never got updated

The venue address was right when you put it in. Then the venue changed parking rules, or the ceremony time moved by 30 minutes, or the hotel block code changed. If you don't update the site, guests are working off stale info on the day.

Set a reminder to review the site a week before the wedding. Check every field. Update anything that's changed.

4. Too much customization breaking the design

This is the custom-colour trap. You liked the template, so you signed up, and then you changed the main text colour to match your wedding palette. Except now the text is pale peach on a cream background and nobody can read it.

I wrote about this in more depth in custom vs. template wedding websites. The short version: platforms that let you change everything without guardrails are letting you break the design. Pick a builder with thoughtful constraints, or stick closer to the template's original colour palette.

5. Missing an RSVP deadline

A form with no deadline gets ignored. Guests tell themselves they'll RSVP "later" and then forget. The deadline is the forcing function that turns "I'll get to it" into "I'll do it now."

Put the deadline visibly on the RSVP page, in the invitation, and in the reminder emails. If your platform's RSVP form doesn't let you set a deadline, that's a sign the platform isn't really built for guest tracking.

6. Confusing navigation

A good wedding website navigation is short, plainly labelled, and puts the important items first. "Home, Details, RSVP, Registry" beats "Welcome, Our Story, The Day Of, What You'll Need, Our Wishes" every time.

7. Spelling and grammar mistakes

This sounds obvious. It happens on almost every wedding website I review. Names misspelled, venue addresses with typos, dates formatted inconsistently.

Before you launch, read every word on the site out loud. Have your partner do the same. Have one other person (a family member, a wedding-party friend) read it fresh. Typos are invisible to the person who wrote them. Someone else will catch them in 10 minutes.

8. Putting your home address on the site

Your home address does not belong on a wedding website. Neither does any guest's home address. If you need to collect mailing addresses for thank-you cards, do it separately (through a private form or after the wedding). If the site needs a return address for RSVPs, use a PO box or the venue address.

Same for phone numbers. Your personal number shouldn't be on a public page. Use a wedding-specific email or the platform's built-in contact options.

9. Forgetting to share the link

You built a beautiful wedding website. Then you didn't tell anyone it exists. Guests assume you're doing paper RSVPs. Aunts call asking about the dress code. You spend the next month answering questions the site already covers.

Share the link actively, not just on the invitation. Put it in the family group chat. Mention it in save-the-date messages. Send a reminder when RSVPs open. My guide on how to share your wedding website covers when and where to share the link.

10. Letting the site expire unexpectedly

Your subscription renews. Or it doesn't, and the site disappears three months after the wedding with all the guestbook messages and photos still inside.

Know what happens to your site after the wedding before you pick a platform. If it's a subscription, set a reminder to cancel. If it's a one-time payment platform, check what the post-wedding window actually is. Export everything you care about before the site goes away. My post on what happens to your wedding website after the wedding walks through the exit plan.

Bonus: the "kitchen sink" mistake

Adding every feature the platform offers whether you need it or not. Countdown timer, travel blog, Spotify playlist, photo carousel, animated hero, bilingual toggle, three different contact forms. A good wedding website is focused, not exhaustive.

Pick the sections you actually need. Turn off the rest. A site with four clear sections beats a site with twelve sparse ones.

The shortest version of this post

Clarity over cleverness. Mobile over desktop. The RSVP button should be the easiest thing to find. Update the site when things change. Don't add what you don't need. And read everything out loud before you launch.

If you're still planning the site from scratch, my full checklist of what to include covers the sections that actually matter. And if you're mid-build and stuck on the timing of it all, when to do each part of the wedding website has the month-by-month version.
