Reference

App Store links: the questions people actually ask

Short answers to the twenty questions that come up most, with links to the full explanation for each.

Uncomfortable

Your Ads Manager is lying to you about clicks

Every ad platform counts a tap that reached a blank page exactly like one that reached the store. There is no column for the difference, and there never will be.

Money

What one broken bio link costs per month

A working model with real numbers: audience size, tap rate, the share that dies on iOS, and what it adds up to over a year.

Uncomfortable

Why your agency never found this problem

It is not incompetence. The failure is invisible in every report an agency looks at, and testing habits actively hide it.

Context

Apple and Meta both benefit when your link breaks

Neither company has a reason to fix the blank page, and understanding why explains all the workarounds.

Meta ads

Install campaigns look better than traffic campaigns for a reason nobody mentions

The gap between the two objectives is not just optimisation. One opens the store natively and the other sends the tap into a browser that cannot.

Myths

Nine things people believe about store links that are wrong

Short corrections to the assumptions that keep this problem alive, each with what is actually true.

Verticals

Subscription apps lose the most from this, and notice it last

High LTV, expensive acquisition and a paywall funnel that hides the leak behind trial numbers.

Seasonal

Check your links before the season, not during it

When most of the year's acquisition happens in six weeks, a broken link costs more than the other eleven months combined.

Creators

The link you hand a creator is the one thing you cannot fix later

Once it is in someone else's bio or video description, you do not control it. What to give them so it keeps working.

Practice

A one-hour audit that finds where your taps disappear

Six checks in order, each with what a healthy result looks like and what to do when it is not.

Practice

Links break silently, so watch them like you watch uptime

Uncomfortable

The worst link setups we have seen, and what they cost

Five real arrangements from live accounts, why each one loses traffic, and the fix for each.

Money

What happens if you just leave it broken

An honest accounting of the do-nothing option, because sometimes it is the right call.

Practice

The cheapest growth win available to most app teams

No creative work, no product changes, no new budget. Just taps that already exist arriving where they were supposed to.

Installs dropped after launch week and nobody changed anything

Four mechanical explanations for a post-launch decline, in the order worth checking, starting with the one nobody checks.

Metrics

Why published conversion benchmarks make this worse

Industry averages include everyone's broken links, so a leaking funnel looks perfectly normal against them.

The first week after launch, in the order that matters

What to check on day one, day three and day seven, with the mechanical checks before the interpretive ones.

Which link should you use? A decision tree

Six questions that lead to the right link type for your case, without a vendor pitch at the end of each branch.

Comparison

What a link-in-bio page costs you at the store step

The extra tap is the small problem. The store button on that page fails the same way any store link does.
