Latest Trends in eCommerce Marketing

Common Mistakes eCommerce Brands Make

Avoid these common pitfalls to ensure your eCommerce strategy stays on track:

  • Slow Site Speed and Poor Mobile UX: Slow load times and a subpar mobile experience can frustrate users, resulting in high bounce rates and lost sales.
  • Over-reliance on Ads: Relying solely on paid advertising without a balanced organic strategy can lead to unsustainable costs and missed long-term growth opportunities.
  • Neglecting Email Marketing and Retention: Focusing only on customer acquisition without nurturing existing relationships, like email marketing, can hinder repeat business and long-term customer loyalty.

eCommerce Marketing ROI – What to Expect

When investing in eCommerce marketing, here’s what you should expect in terms of ROI:

  • SEO vs. PPC: SEO provides long-term, organic growth, while PPC delivers immediate results through paid campaigns. A balanced approach that incorporates both can maximise results.
  • Key Performance Indicators: Measure success with key metrics like conversions, Customer Acquisition Cost (CAC), and revenue growth to ensure you’re reaching your business goals.
  • Agency vs. In-house: Consider whether to work with an agency for expertise, scale, and efficiency, or keep it in-house teams for more control. The right choice depends on your resources, goals, and desired outcomes.
