In ecommerce, two acronyms dominate the conversation: SEO (Search Engine Optimisation) and CRO (Conversion Rate Optimisation). Both are essential for driving growth, but they serve very different purposes. 

While SEO is about getting people through the digital door, 

 is about encouraging them to complete a purchase once they arrive and complete their desired action. Understanding the difference between ecommerce SEO and CRO and how they work together is key to building a high-performing online store that not only attracts traffic but also converts visitors into loyal customers.

 is the process of optimising your website so that it appears higher in search engine results for relevant keywords. When your product and category pages are visible to potential customers on platforms like Google, you increase the chances of attracting organic traffic without relying solely on paid ads.

SEO is a long-term strategy. It takes time to build momentum, but the rewards are sustainable and consistent. To succeed with SEO in the ecommerce space, your strategy needs to cover several key areas, including:

What is CRO (conversion rate optimisation)?

, on the other hand, is all about what happens once users land on your site. 

CRO is the process of improving your website to boost the percentage of visitors who take a desired action, whether that’s buying a product, filling in a form, signing up to a newsletter, or adding an item to the basket.

CRO can offer quicker wins than SEO. Small changes can often lead to significant improvements in performance, especially if your site already has a steady flow of traffic.CRO is a practical, data-driven discipline that revolves around refining the customer journey.

 are both essential to online success, they focus on entirely different stages of the customer journey. SEO is about attracting the right people to your website, while CRO is about encouraging those people to take action once they arrive. To get the most from your ecommerce store, it’s important to understand how these two strategies differ in their goals, methods, and the tools they rely on. 

SEO: The main objective of ecommerce SEO is to increase organic visibility in search engines like Google. This means more potential customers can discover your products through relevant search terms.

CRO: CRO is focused on turning those visitors into customers by improving your site’s usability, design, and messaging to encourage conversions.

SEO: Primarily concerned with off-site and on-site elements that influence search engine rankings – such as keyword usage, site architecture, technical performance, and backlinks.

CRO: Focuses entirely on the on-site experience, looking at how users interact with your pages and what can be improved to boost conversions (e.g. clearer CTAs, better product images, faster load times).

SEO: Results often take several months to appear, especially in competitive niches. However, once rankings improve, traffic tends to be steady and cost-effective.

CRO: Changes can deliver results more quickly. You might see an uplift in conversion rates within days or weeks after running A/B tests or improving key pages.

SEO: Tracks metrics like keyword rankings, organic traffic volume, impressions, and click-through rates from search engines.

CRO: Monitors performance indicators such as conversion rate, bounce rate, average order value (AOV), and the number of completed goals (e.g. purchases or sign-ups).

SEO: Often uses tools like Google Search Console, Ahrefs, SEMrush, and Screaming Frog to analyse rankings, technical health, and backlink profiles.

CRO: Relies on tools like Google Analytics, Hotjar, Microsoft Clarity, and Optimizely to assess user behaviour, run experiments, and test different versions of pages.

SEO: Strategic work often involves long-form content creation, keyword research, metadata optimisation, and technical audits – all with the aim of ranking higher and attracting more relevant traffic.

CRO: Strategy is more experimental and iterative. It’s about using data to identify friction points in the customer journey and testing solutions to improve performance.
