Eight mistakes people make launching a first website

Nearly every problem that shows up in someone's first week with a live website falls into one of a small number of familiar patterns. None of them are complicated once you know to look for them — they are simply things nobody thought to check before the site went public. Most cost nothing to avoid; they just need to be thought about in the right order, usually before the domain goes live rather than after.

1. Cancelling the old hosting too soon

If you are replacing an existing website, cancelling the previous hosting the moment you change DNS is a common and entirely avoidable mistake. DNS changes take time to spread across the internet, and during that window different visitors are still being sent to the old server. Keep the previous hosting active until you have confirmed the new site is answering everywhere, not just from your own connection. This matters just as much for email as it does for the website — mail sent to the domain during the switchover can still be routed through whichever server the sender's own connection currently resolves to.

2. Testing only on your own device

A site that looks fine on the computer that built it can still be broken for everyone else — a cached old version, a browser extension quietly fixing something, a screen size nobody else uses. Test from a private browser window, a different device, and mobile data before assuming the site genuinely works. It is also worth asking someone else entirely to load it, ideally from a network you have never used yourself, since a shared home or office connection can hide problems that only appear elsewhere.

3. Skipping a proper preview before going live

Pointing a domain at a hosting account and hoping it works is a needless risk when previewing first is straightforward. Previewing a site before changing DNS lets you catch problems while only you can see them, rather than after the domain change has already gone out to visitors.

4. Leaving placeholder content in place

Template text, sample images, and dummy filler paragraphs left over from building the site are the single most common thing found on a first visit to a newly launched page. It is worth a dedicated pass through every page — not just the homepage — specifically looking for content that was never actually replaced.

5. Forgetting that email is a separate setup

Pointing a domain at hosting does not automatically mean email at that domain is ready to go. Mailboxes need creating, and the domain's mail records need to be correctly pointed, which is not always automatic if DNS for the domain is managed somewhere other than the hosting account. Test sending and receiving mail from a new address before relying on it for anything important — a contact form that emails an address nobody has actually verified is a quiet failure waiting to happen. It is worth checking this well before launch day too, since a mailbox that has never actually sent or received a message is not something you want to discover is broken the same week a customer tries to reach you.

6. Choosing a plan based on price alone

The lowest-priced available plan is sometimes the right one, but only when it is genuinely enough for what the site does. A plan too small for its site tends to show up later as unexplained slowness or resource warnings, which usually costs more time to diagnose than the amount saved by starting a tier lower. How to choose a hosting plan you will not outgrow covers matching a plan to an actual site rather than guessing from a price list.

7. Having no backup before making the first real change

The first update, plugin install or design tweak after launch is exactly the moment a backup matters most, and exactly the moment it is most often missing, because nobody set one up while the site still felt like "just getting started". Set up backups as part of launching, not after the first thing goes wrong. Backing up your website covers doing this properly from day one.

8. Not checking the site again after DNS has settled

A site that was carefully tested before launch can still develop small issues once it is genuinely public — real traffic, real form submissions, and search engines actually crawling it all surface things that quiet pre-launch testing does not. Check back a day or two after going live, once DNS has fully spread, rather than treating the initial test as the final word. Look specifically at anything that depends on real visitors to trigger it — a form's email notifications, a checkout process, an analytics tag — since those are the parts most likely to have gone untested during a quiet pre-launch check.

Avoiding all eight at once

None of these require special expertise to avoid — they mostly require doing things in the right order and not skipping a step because the site "seems to work". The website launch checklist puts all of the above, plus the rest of what is worth checking before going live, into a single ordered list you can work through from top to bottom rather than relying on memory.
