What to Look for in an eCommerce Marketing Agency

Platform experience

Choosing the right eCommerce marketing agency means finding one with hands-on experience in your specific platform - whether that's Shopify, Magento, or WooCommerce. Having technical familiarity ensures smooth implementation and faster results.

Revenue-focused KPIs

Prioritise agencies that track revenue-focused KPIs. It's not enough to drive traffic; you need a partner that ties their efforts directly to revenue growth.

Proven CRO & retention strategies

If you're looking to scale, proven strategies for conversion rate optimisation (CRO) and customer retention should be non-negotiable. These are what separate vanity metrics from meaningful outcomes.

Transparent pricing & contracts

Pay close attention to how the agency structures pricing and contracts. Avoid providers with vague deliverables or rigid lock-in periods that limit your flexibility.

Technical capabilities

Finally, assess their technical capabilities. Can they handle GA4 setup, schema markup, page speed improvements, and backend integrations? These details make a real difference to your long-term scalability and visibility.

FAQs

How much does an eCommerce marketing agency cost in the UK?

Most agencies charge £1,500–£5,000/month depending on services and scope of the campaign. Some offer performance-based pricing or fixed retainers.

Can I hire an agency just for SEO or PPC?

Yes, many agencies offer service-specific packages. If you’re only looking to improve organic traffic or paid ads, you can hire accordingly.

Do these agencies work with Shopify and WooCommerce?

All agencies listed are platform-agnostic, but several specialise in Shopify or WooCommerce specifically. 

What should I ask during an agency discovery call?

Ask about platform experience, case studies, client retention, data reporting processes, and what success metrics they prioritise.

Do I need to commit to a long-term contract?

Some agencies offer month-to-month, but most require a 3- to 6-month minimum to show results. Clickslice set themselves apart here by offering a rolling contract - you can stop at any time.
