Key takeaways
- A good ecommerce marketing strategy starts with margins, not channels.
- Fix conversion first: more traffic to a leaky store just costs more.
- Balance fast channels (Shopping ads) with compounding ones (SEO, email).
- Grow repeat purchases: existing customers are your cheapest sales.
Start with your numbers
Every effective ecommerce marketing strategy starts with a few figures. Without them, it's impossible to know how much you can afford to spend to win a customer, or which channels are really profitable.
| Metric | Why it matters |
|---|---|
| Gross margin | How much of each sale is left after product and fulfilment costs. |
| Average order value (AOV) | How much a typical order is worth. |
| Conversion rate | The share of visits that become orders. |
| Customer acquisition cost (CAC) | What you spend in marketing to win a new customer. |
| Repeat purchase rate and lifetime value | How much a customer is worth over time, not just on the first order. |
Set a target cost per acquisition: if your margin on a typical first order is £30 and customers usually buy again, you can decide how much of that you're willing to spend to win them. That number guides every ad budget.
Fix conversion before buying traffic
Doubling your conversion rate has the same effect on sales as doubling your traffic, and it's usually cheaper. Before scaling ads, make sure your store does its job:
- Fast pages on mobile, where most shoppers browse.
- Clear product pages with great photos, honest descriptions and visible delivery and returns information. See our product page best practices.
- A simple checkout with guest checkout and popular payment methods. Our guide to reducing cart abandonment covers the details.
- Trust signals: genuine reviews, secure payment and real contact details.
Choose the right mix of channels
| Channel | Speed | Best for |
|---|---|---|
| Google Shopping and Performance Max | Fast | Capturing people already searching for your products |
| Ecommerce SEO | Slow, compounding | Long-term traffic to category, product and guide pages |
| Email and SMS | Fast with an existing list | Repeat purchases, abandoned carts and launches |
| Paid social | Fast | Creating demand for products people don't search for yet |
| Organic social and content | Slow | Brand, community and trust |
Most stores start with Shopping ads for immediate sales and SEO for long-term growth, then add email automation to increase repeat orders. Our guides to Google Shopping feeds and ecommerce SEO explain both.
Grow repeat purchases
Winning a new customer is expensive; selling to an existing one is not. Build retention into your strategy from the start:
- Welcome series for new subscribers and first-time buyers.
- Abandoned cart and browse reminders, sent quickly and politely.
- Post-purchase emails with care tips, review requests and related products.
- Win-back campaigns for customers who haven't ordered for a while.
- Replenishment reminders for products people run out of.
Our email automation setup (welcome, abandoned cart and win-back flows) starts from £800 as a one-off project.

Common mistakes
- Judging channels on revenue instead of profit.
- Scaling ad spend before the store converts well.
- Discounting so often that customers wait for the next sale.
- Ignoring existing customers in favour of new ones.
- Unreliable tracking, so nobody trusts the numbers.
Keep promotions honest. UK consumer law bans fake "was" prices, false urgency and misleading reviews. Under the DMCC Act 2024, the CMA can fine businesses directly for these practices.
Ecommerce marketing FAQs
Which marketing channel is best for a new online store?
Google Shopping usually brings the fastest sales for products people search for, while SEO and email build longer-term growth. Paid social works well for products that need to create demand.
How much should I spend on marketing?
Work backwards from your margin and the cost you can afford to win a customer, then start with a test budget and scale what's profitable.
What's a good ecommerce conversion rate?
It varies widely by product, price and traffic source, so compare against your own history and aim to improve it steadily rather than chasing a generic benchmark.
How long does ecommerce SEO take?
Usually several months to build momentum, depending on competition and your site's starting point. It's best paired with paid channels for sales in the meantime.
The bottom line
A profitable ecommerce marketing strategy starts with your numbers, fixes conversion before buying traffic, mixes fast and compounding channels, and grows repeat purchases. Track profit by channel, review monthly and scale what works.
