After launch: the first 90 days

What happens after a website or app launch: the first 90 days — measure, fix, and improve from real usage. The post-launch loop I run instead of going quiet.

After launch: the first 90 days cover

The first 90 days after launch are for learning, not coasting: watch real usage, fix what's confusing or broken, and improve the few things that move your goal. A launch is the start of the work, not the finish. The sites and apps that succeed treat the first three months as a tight loop — measure, prioritize, ship a small improvement, repeat — instead of going silent the day they go live.

What should you do right after launch?

Watch how real people use it. Check that analytics and forms are firing, see where visitors actually go versus where you expected, and catch the confusing or broken bits that only show up with real traffic. The first week is for fixing friction you couldn't see in testing. Real usage tells you more in seven days than months of planning did — so the job right after launch is to read it and respond, fast. A short launch-week checklist helps: confirm analytics is recording, submit the sitemap to Google Search Console, test every form end to end on a real device, and watch for any error spikes. The first week is less about new features and more about making sure what you launched actually works for real people.

What does the 90-day loop look like?

A simple rhythm: measure what's happening, pick the single highest-impact fix or improvement, ship it, then look again. Early on that might be clarifying a confusing page or speeding up a slow one; later it's improving conversion on the steps that matter. Small, steady improvements compound over a quarter into a meaningfully better result. The discipline is doing one useful thing at a time, guided by data, instead of redesigning everything at once. Concretely, I run it weekly: each week, look at the numbers, pick one improvement that moves the goal metric, ship it, and note what changed. Over twelve weeks that's a dozen deliberate, measured improvements — which compounds into a far better product than one big redesign you can't attribute to anything.

What's the biggest post-launch mistake?

Going quiet. Treating launch as the finish line means the product never improves from what real users teach you, and early friction calcifies into lost customers. The opposite mistake is thrashing — changing everything at once so you can't tell what worked. The sweet spot is one measured change at a time. Launch quietly, then iterate deliberately; that's where the real gains live, not in the launch-day splash. A close second is vanity-metric tunnel vision — celebrating signups or pageviews while the number that actually matters (activation, conversion, retention) goes unwatched. Pick the one metric that maps to real value, and let it, not applause, decide what you build next.

What should you measure in the first 90 days?

Three things, in order of importance: activation (do new users reach the core value — the "aha" moment — or drop before it?), retention (do they come back?), and conversion (do they take the goal action — buy, book, subscribe?). Traffic and signups are easy to celebrate but mean little if people arrive and bounce. The honest scoreboard is whether real users get value and act on it. I instrument those few events before launch so the answers are there in week one, not reconstructed from memory later — the setup I cover in analytics from day one.

How is iterating different from a redesign?

Iterating is a scalpel; a redesign is a sledgehammer. After launch, the temptation when something underperforms is to redo the whole thing — but a full redesign throws away what's working along with what isn't, and you can't tell which change caused which result. Iteration is the opposite: one targeted improvement at a time, measured against the metric, kept if it helps and reverted if it doesn't. It looks slower but compounds faster, and it's how a product gets genuinely better instead of just different. Save the redesign for when the data says the whole direction is wrong, which is rare.

How do I run the first 90 days?

I instrument the core events before launch, then use the first weeks to fix friction and improve the metric that matters, the way I set up in analytics from day one. It's the same iterate-from-usage model behind my services and how I shipped Coloring Forge (case study) — launch the core, learn, improve. The plan starts before launch day, so the loop is already running.
