A sales funnel is the buyer's path from first contact with your store to a paid order, broken into stages. At every step part of the audience drops out, which is why the funnel narrows. You measure a funnel through the conversion of transitions between stages: that shows exactly where the store loses orders and what to fix first.
Why an online store needs a funnel
Without a funnel, a store owner sees only two numbers: how much was spent on ads and how many orders came in. If orders are few, the reason is unknown — maybe traffic is low, or maybe traffic is fine but people never reach payment. The funnel breaks this black box into stages and reveals the specific bottleneck.
The practical value is simple: raising the conversion of one step by a few percent is usually cheaper than growing traffic by the same amount. Advertising costs money every month, while a fixed cart page works for free and permanently.
Stages of the sales funnel
For an online store the classic funnel has five or six steps. Names may vary; the substance does not.
1. Impressions / reach
How many people saw you: ad impressions, impressions in search results, reach of social posts. This is the widest part of the funnel and the only stage you scale with money.
2. Visit to the site
Who clicked and actually arrived. Here ad quality and promise-to-page match decide everything: if the ad promises one thing and the page shows another, the person leaves within seconds.
3. Product view
The visitor reached a product page — that is, found what they were looking for. A drop at this step means a problem with navigation, categories or on-site search.
4. Add to cart
The product was interesting enough to be picked up. Price, availability, photos, specifications, delivery times and reviews decide the outcome here.
5. Checkout started
The buyer moved to checkout. This is the most expensive traffic in the funnel — the person is almost a customer, and every loss here costs the most.
6. Paid order
The final stage. Stores with cash on delivery should add one more step "confirmed order" — because part of the placed orders is never collected.
How to measure the funnel: formulas
All funnel maths comes down to three formulas.
Online store conversion = orders / visits × 100%
Stage conversion = count at the next stage / count at the current stage × 100%
End-to-end conversion = the product of all stage conversions
Example: 10,000 visits, 3,000 product views, 600 add-to-carts, 300 checkout starts, 150 paid orders. Stage conversions: 30%, 20%, 50%, 50%. Overall store conversion: 150 / 10,000 × 100% = 1.5%. It is immediately clear that the weakest step is product view to cart.
Next you convert this into money, and that is where the funnel becomes a decision tool:
- Average order value = revenue / number of orders.
- Revenue per visit = revenue / visits. Shows what one visitor is worth and how much you can pay per click.
- Lost revenue of a stage = people who dropped out × conversion of the rest of the funnel × average order value. This number tells you which step to fix first.
Stage metrics: what to watch
Universal "normal" numbers do not exist — they differ by niche, product, and traffic source. So use your own dynamics as the benchmark: calculate your metrics monthly and compare with the previous period.
| Stage | Metric | Warning sign and what it means |
|---|---|---|
| Impression → visit | Ad / snippet CTR | Low CTR: the ad does not match the query, or its price is not competitive |
| Visit → product view | Share of visits reaching a product page | Most people leave the landing page: poor navigation, slow site or irrelevant traffic |
| View → cart | Add-to-cart rate | Products are viewed but not taken: weak photos/descriptions, out of stock, unclear delivery |
| Cart → checkout | Share moving to checkout | A shipping-cost surprise at the cart stage is the most common cause |
| Checkout → payment | Checkout completion | Long form, forced registration, too few payment methods |
| Payment → repeat purchase | Share of repeat orders | Customers do not come back: no service, no newsletter, no reason to buy again |
The data for these calculations comes from analytics: orders and revenue by period are visible in the Turboshop store dashboard, and visitor behaviour in the web analytics system you connect to the site. What the platform does out of the box is on the store features page.
Where stores lose orders most often
- Irrelevant traffic. Ads bring people who do not need the product. A cheap click does not mean a cheap order.
- A slow or awkward mobile site. Most people arrive on a phone; every extra second of loading takes away part of the funnel.
- Out of stock. The most expensive loss: the person already wanted to buy. Accurate stock levels are basic hygiene.
- Hidden costs. Shipping fees that appear only in the cart destroy trust instantly.
- Complicated checkout. Forced registration, ten form fields, no suitable payment method or delivery service.
- Silence after the order. No confirmation and no tracking leads to returns and uncollected parcels.
- No work with the customer base. The store buys each customer from scratch instead of selling to existing ones.
Traffic is what you pay for. Conversion is what you control. A store that fixes one funnel step every month overtakes the one that simply raises its budget.
Abandoned carts: a story of their own
An abandoned cart is when a product was added but the order was never placed. These are the hottest lost customers in the whole funnel, so work with them systematically:
- Show the full price including delivery as early as possible — already on the product page.
- Allow ordering without registration, with a minimum of fields.
- Offer several payment and delivery options — choice removes the barrier.
- Remind about the cart by email or message within a few hours.
- Display return terms and contacts on the checkout page — it removes anxiety.
How to increase online store conversion
The order of work should be: first find the weakest stage using the formulas above, then fix exactly that one. What usually delivers the biggest effect:
- Product pages. Several quality photos, complete specifications, honest availability, clear delivery times, reviews.
- Speed and mobile version. The cheapest way to lift the whole funnel at once.
- Simplified checkout. Minimum fields, guest checkout, saved details.
- Quality traffic. Precise keywords and the right audiences lower cost per order at the same budget; the basics are on the SEO for online stores page.
- Trust. Contacts, return terms, real photos — everything showing there are people behind the store.
- Repeat sales. The cheapest conversion in a store is the one you already paid for once.
If you are still planning your store, most of these are best built in from the start — we covered the step-by-step order in the guide on how to open an online store.
Frequently asked questions
What online store conversion rate is considered normal?
There is no single norm: it depends on the niche, product price, traffic source and even the season. The correct benchmark is your own dynamics: calculate conversion monthly with "orders / visits × 100%" and compare it with previous periods and across channels.
How many stages should a funnel have?
As many as you can actually measure. Start with four: visit → product view → cart → order. Once that data is stable, add checkout, repeat purchases and order confirmation.
How is a funnel different from conversion?
Conversion is one final number (orders / visits). A funnel breaks that number into steps. Conversion says there is a problem; the funnel says where it is.
How do I measure a funnel when sales are still low?
On small numbers percentages jump around, so look at longer periods — a month or a quarter — and at absolute values. Until statistics accumulate, focus on the obvious barriers: availability, site speed, completeness of product pages, ease of checkout.
