Getting a Real-World Perspective on SEO Partnerships

To get beyond the theory, we had a chat with 'Sarah Jenkins', a Digital Marketing Manager for a UK-based retail brand, about her experience.

Us: "Sarah, what was the biggest challenge you faced when first hiring an SEO agency in London?"

Sarah: "Honestly, it was transparency. The first agency we worked with produced beautiful reports full of vanity metrics—traffic was up, but qualified leads and sales weren't. It felt like we were paying for smoke and mirrors. Our key learning was to find a partner who could directly correlate their SEO efforts to bottom-line results, like revenue and lead quality. We needed someone who would talk about conversion rate optimisation, not just rankings."

Us: "So, what changed in your approach?"

Sarah: "Now, we start with a paid audit. We ask two or three shortlisted agencies to conduct a technical and content audit of our site. It costs a bit upfront, but it’s invaluable. You see their real expertise, their communication style, and their strategic thinking before you commit to a 12-month contract. It’s a test drive. We look for those who identify opportunities we missed, not just the obvious fixes."
