It was a real pleasure working with Seed on our recent SEO project. As an organisation with nearly 30 years of history, we knew our website needed technical updates to stay accessible and visible to service users and supporters alike. We're delighted with the results and wouldn't hesitate to recommend them.

We joined Seed in March aware that our Social was underperforming. In the first week of Seed posting to our Instagram account we received more likes than we ever had. A fantastic achievement!

Our approach
Our CRO methodology
We don't guess. We research, hypothesise, test, and scale. Every improvement is grounded in real user behaviour and validated through rigorous experimentation. Our methodology combines quantitative analytics with qualitative user research to understand not just where visitors drop off, but why. This evidence-based approach means every change we make is backed by data, every test has a clear hypothesis, and every insight compounds into a deeper understanding of what drives your customers to convert.
We map your entire conversion funnel using heatmaps, session recordings, scroll depth analysis, and funnel analytics, identifying exactly where and why visitors are dropping off. We complement this quantitative data with qualitative user research: moderated testing sessions, customer interviews, and survey data that reveals the motivations, fears, and objections your visitors experience. This dual approach ensures we understand the full picture before designing any tests.
CRO/UX FAQs
Common CRO/UX questions
You need sufficient traffic to run statistically valid tests, typically 1,000+ conversions per month per page being tested. For lower-traffic sites, we focus on qualitative research, UX improvements, and expert heuristic reviews.
