How We Structure an Ecommerce Growth Funnel: Acquisition, Conversion and Retention

An ecommerce marketing funnel has three jobs: bring in people who are likely to buy, make it easy for them to buy once they arrive, and give them a reason to buy again. In practice we look at it as seven connected parts: acquisition, the landing experience, product and collection structure, conversion, remarketing, retention, and measurement across all of it. When growth stalls, the cause is usually in one of the middle parts, which is why more traffic is rarely the first fix.

The textbook version (awareness, consideration, purchase) is fine as a diagram, but it does not tell a store owner what to change on Monday. The version below is organised around the decisions that actually move revenue, and the order we check them in.

What an ecommerce funnel needs to do

For most stores, the funnel is the whole path from the first ad, search result or social post to the second and third order, and each part affects the others:

• an ad that promises something the product page does not deliver wastes the spend
• a strong product page cannot fix traffic that was never going to buy
• a good first order is worth much less if nothing brings the customer back
• none of it can be improved reliably if the tracking is wrong

So the question is less "how do we get more people into the top" and more "where are the people we already have dropping out, and why".

Acquisition: bring in the right traffic

Acquisition covers paid search and shopping, paid social, organic search, marketplaces, email capture, partnerships and anything else that brings new people to the store. The aim is traffic from people likely to buy, at a cost the margin can carry.

Useful questions here:

• Which channels bring customers who actually buy, and at what cost?
• Are campaigns optimised for purchases, or for clicks and traffic?
• Is spend split sensibly between finding new customers and re-engaging people who have already visited?
• Is the brand paying to win searches for its own name that it would mostly win anyway?

When BlueAnt moved into direct-to-consumer sales right before Black Friday, the paid media account was rebuilt around how people buy: clear product and category structure, a proper split between prospecting and retargeting, and campaigns set up to drive purchases rather than traffic. The detail is in the BlueAnt case study.

Landing experience: does the page match the ad or search?

The page someone lands on has to continue the conversation the ad or search started. If an ad shows a specific product and price, the click should go to that product, not the homepage. If a search was for a category, the landing page should be that category, filtered sensibly.

Mismatch here is one of the most common reasons paid traffic does not convert. It shows up as high bounce rates from paid channels, low add-to-cart rates on landing pages, and customers searching the site again for the thing they just clicked on.

Product and collection structure

How the range is organised affects both acquisition and conversion. Clear collections give search engines and shopping feeds sensible pages to show, and give customers a way to find what they want without scrolling through everything.

Good structure usually means collections built around how customers shop (by use, room, size or occasion, as well as by internal category), product titles that describe the product, variants grouped properly, and filtering that works on mobile. For My Divine Home, a homewares and furniture store in Busselton, part of the work was operational: products came from the point-of-sale system without shipping information, so larger pieces could only be collected in store. Giving every product a shipping size and pricing delivery by size and region meant more of the range could be bought online at all.

Conversion: where customers stop

Conversion is where most stores have the most room to improve, and where guesswork is most expensive. Rather than applying generic tips, look at where customers actually drop out:

• product page to add to cart
• cart to checkout
• checkout to payment
• the specific step where mobile users leave and desktop users do not

Common causes include unclear delivery costs and timing, missing product information, weak images, slow pages, surprise fees at checkout and limited payment options. Our article on ecommerce mistakes that hurt conversion goes through these in more detail.

Remarketing without pretending every visitor is equally valuable

Remarketing works best when it reflects intent. Someone who abandoned a checkout is in a very different position from someone who viewed the homepage for three seconds. Treating them the same wastes money and annoys the people who were never close to buying.

Practical segmentation might separate cart and checkout abandoners, product viewers, past purchasers and email subscribers, with frequency limits and exclusions so recent buyers are not chased with ads for the thing they just bought.

Retention and repeat purchase

For many stores, the margin is made on the second and third order, because acquiring the first one costs the most. Retention covers post-purchase email and SMS, product education, replenishment reminders where products run out, loyalty offers where they genuinely suit the business, and the delivery and returns experience itself.

Email and SMS marketing in Australia must meet the Spam Act: consent, clear identification of the sender, and a working unsubscribe. The ACMA's guidance on avoiding spam sets out what that means in practice.

Measurement across the whole journey

Measurement ties the funnel together. At a minimum, purchases need to be tracked accurately in the store's analytics and in each ad platform, with values, and the business needs a view of revenue and cost that does not depend on any single platform's own reporting.

Server-side tracking, such as Meta's Conversions API and Google's enhanced conversions, helps platforms receive more complete conversion data. It does not replace a sensible view of overall marketing cost against revenue and margin.

Where we would look first when growth stalls

When a store's revenue has flattened, this is roughly the order we work through:

1. Check tracking is accurate, so decisions are based on real numbers.
2. Look at conversion by device and by traffic source, to find where customers drop out.
3. Check landing pages match the ads and searches sending traffic to them.
4. Review product and collection structure for the best-selling and highest-margin lines.
5. Review retention: repeat purchase rate, email and post-purchase flows.
6. Only then decide whether more acquisition spend is the right next step.

Our article on the ecommerce growth levers we review before increasing ad spend looks at that last decision in more detail.

If traffic is growing but revenue is not moving with it, we can review the store, campaigns and customer journey together. Our ecommerce work covers the store and its marketing as one system, and paid media is where campaign structure and spend sit.
