Website launch checklist — 8 checks that actually matter

Know what most often goes wrong when launching a first site? Not the design. The site looks great on your machine — and breaks for the very first visitor: won't open on a phone, links go nowhere, the form doesn't submit. Because you tested on your machine, your browser, your internet.

This checklist is about the stranger who arrives for the first time. Eight checks, each catching a real embarrassment. Run them before you invite people. It's not about perfectionism — it's about "the site works for more than just me."

1. Open the site on a phone

Don't shrink the browser window — grab a real phone. More than half your visitors will use one. Check: text reads without zoom, buttons are tappable with a finger, nothing runs off the edge. The most common failure is a site that's perfect on a laptop and broken on an iPhone.

2. Click every link and button

Does each link go where it should? Does "Submit" actually submit? A broken link or a dead form at launch is a lost person who won't come back. Walk the site like a first-time guest, clicking everything.

3. Check the title and description in search

These are meta tags: title and description. Send the link to yourself in Telegram — you'll see how the site looks as a preview. A bare grey card with no description = fewer clicks. It's also the basis of SEO, so people can find you at all.

4. Get secrets out of the code

Critical. API keys, passwords, tokens must not sit in code that ships to the browser or to GitHub. Their place is environment variables. A leaked key in a public repo is found by bots within minutes, and you'll be the one paying for it.

5. Check load speed

If the site takes longer than three seconds, some people will close it before it loads. The usual culprit is heavy images. Compress them (free services exist) and the page flies. Open the site "cold," with no cache, to see it as a new guest does.

6. Run the full scenario

Not individual buttons, but the whole path end to end: arrived → signed up → did the main action → left. This surfaces the seams that worked alone but not together. If the site has login, check both signup and returning.

7. Add analytics

At least a simple counter. Without it, after launch you're in total darkness: how many came, from where, what they clicked. Five minutes to install — and you can see whether the launch is working instead of guessing.

8. Test on someone else's device

The final step. Ask a friend to open the site on their own phone without your hints. You'll watch a real person stumble where everything is obvious to you. It's the best test of all — and free.

FAQ

What's the single most important item?

Items 1 (phone) and 4 (secrets). A broken mobile view loses half the audience instantly; a leaked key can cost real money. The rest matters, but these two you cannot skip.

How long does the whole checklist take?

About an hour for a small site. That's incomparably cheaper than fixing a public failure in front of your first visitors and losing their trust at the start.

Do I need all this for a side project?

The minimum — yes. Even for a "show my friends" project, run items 1, 2 and 4: mobile view, working links, no secrets in code. That's half an hour that saves you embarrassment. The full list is for a serious launch — and don't forget the security checklist.
