Choosing What to Fix First: A Prioritisation Method for Small Stores
You cannot fix everything, and the order matters. A simple scoring method sized for one person's time: size of the leak, certainty of the evidence, and cost of the fix, in that order of honesty.
The short answer
Prioritise by three factors, scored roughly and honestly: how many buyers the problem plausibly costs (traffic reaching the step times the size of the drop), how sure you are the problem is real (evidence strength, from a guess up to recordings of people failing), and what the fix costs in time and risk. Work the top of that list, one or two items a month, and re-score monthly as the funnel changes. The method matters less than the discipline: a written order, defended by numbers, beats a month of fixing whichever page annoyed you most recently.
Factor one: the size of the leak
A problem's cost is bounded by the traffic that meets it. A confusing returns policy read by 30 people a month cannot cost more than 30 decisions; a slow product page seen by 3,000 can cost hundreds. Estimate the leak as: sessions reaching the step, times the shortfall you believe exists. You will not know the shortfall precisely - a step rate visibly below its neighbours, or recordings of repeated failure, are enough to rank. Precision is not the point; order of magnitude is. Big leaks first is the whole of factor one.
Factor two: how sure are you
Rank evidence in this order: people observed failing (recordings, usability sessions, support complaints quoting the page) beats step-rate anomalies, which beat heatmap impressions, which beat a competitor doing it differently, which beats a blog post saying everyone should. Weak-evidence items are not banned - they are queued behind strong-evidence ones, or converted into research tasks: watch ten recordings of the page before rebuilding it. This factor is where small stores save the most time, because most fix lists are half folklore.
Factor three: cost and risk of the fix
Cost is your hours plus the chance of breaking something that works. A text change on a product template is an afternoon and reversible. A checkout overhaul on a platform you half-control is a week and touches the page that takes money. All else equal, cheap and reversible goes first - not because it is most valuable, but because a small store's scarcest resource is the owner's attention, and quick certain wins fund the patience for bigger ones. Note platform limits honestly: some checkout fixes are simply not available on some plans, and a fix you cannot ship scores zero however big the leak.
A worked ordering
Illustration: a store's candidate list holds (a) product pages load slowly on mobile, step rate down, fix is image compression - big leak, strong evidence, cheap; (b) add reviews to product pages, currently none, fix is an app and moderation time - medium leak, medium evidence, medium cost; (c) redesign the homepage hero - unknown leak, weak evidence, medium cost; (d) rewrite checkout reassurance copy - small leak, weak evidence, cheap. The method orders them a, b, d, c. Without the method, (c) usually wins because it is the most visible - which is exactly the failure this page exists to prevent.
Re-score on a rhythm, not on a whim
Fix the list monthly, at the same sitting as your baseline review. New evidence arrives (a step rate moved, a complaint pattern formed), finished fixes leave, and the order reshuffles legitimately. What you must not do is re-prioritise mid-month because a podcast mentioned a tactic. The list is a queue, not a mood board. Stores that hold a queue for six months learn their funnel deeply; stores that chase weekly tactics learn nothing twice.
The list you say no to
Every prioritised list creates a second, shadow list: the ideas explicitly deferred. Keep that list written down with a one-line reason - too costly this quarter, evidence too weak, platform cannot do it yet. Deferred ideas have a habit of returning as urgent suggestions in meetings and podcasts; a written deferral with a reason answers them without a fresh argument each time. Review the deferred list at the quarterly re-score: some items graduate when traffic grows or a platform adds the feature, and a few get deleted as the store's shape changes. Prioritisation is as much the discipline of recorded refusal as of selection, and the recorded refusals are what keep a one-person business from spending the year on other people's priorities.
