SOZO’s clients started asking a question the whole industry was catching up on.
SOZO is a 25-year UK B Corp agency. Christian Goodrich leads its 10-person search team, serving 60+ active ecommerce and lead generation clients across the UK and globally. He has spent 18+ years helping ambitious brands turn SEO, paid search, CRO and AI search into measurable growth, including 10 years as Head of Search at SOZO.
In the last twelve months, every conversation with clients started circling the same question. What does our brand look like on AI search? SOZO’s clients had spent years investing in traditional SEO. Now their buyers were going to ChatGPT, Gemini, and Google AI Overviews to research products before any blue link got a click. Like every agency, SOZO had no clear way to see where their clients stood, because the tooling to measure it barely existed.
“We've been having conversations over the past year with clients, many of whom weren't able to tell us or have any kind of insight into what their brand discoverability was like across AI-driven search.”
Christian Goodrich, Head of SEO & AI Search at SOZOOne agency, a full SME portfolio. The tool had to scale.
The shift in buyer behaviour wasn’t theoretical. Users were bypassing Google entirely, asking AI platforms which marketing automation tools, skincare brands, or B2B vendors they should consider. For agencies like SOZO, that meant client investment in SEO flowed through a channel nobody could yet measure.
SOZO needed something that worked across every account, not a one-off for the biggest clients. The solution had to be deployable on a sustainability-focused DTC brand and a lead-gen B2B client in the same week, with the same playbook.
brightonSEO. A demo. An enterprise partnership.
SOZO found Writesonic through their own research and conversations at brightonSEO, the UK’s largest search marketing event. The team demoed the platform, met the Writesonic team in person at the conference, and onboarded as an enterprise partner six months ago.
Since then, Writesonic has become a core part of SOZO’s AI search delivery. The agency uses it to measure discoverability, surface competitor intelligence, analyse brand sentiment, and prove the impact of every site change to clients.
Three jobs Writesonic does inside SOZO's workflow.
Pre and post-launch measurement. Before any major site change, SOZO establishes a baseline of AI visibility across ChatGPT, Gemini, and AI Overviews. After launch, the same dashboard shows the lift or loss. Clients now see how every strategic decision lands across the AI platforms SOZO tracks.
Action Center. This is where the SEO team starts most mornings. Pre-launch, it surfaces technical blockers that hurt AI discoverability so the team fixes them before the site goes live. It also exposes which Reddit posts, articles, and external sources AI platforms are pulling from when they cite competitors. That competitor intel feeds SOZO’s strategy briefs directly.
“We can now say to our brands where exactly they're positioned in AI search and build a picture for them in a way that we weren't able to do previously.”
Brand Sentiment workshops. SOZO has built a recurring client workshop around Writesonic’s Brand Sentiment feature. The agency walks each client through what AI platforms say about them, whether the sentiment skews positive or negative, and which sources are shaping that perception. The workshop format moves the conversation past rankings to how AI describes each brand and what that does to buyer behaviour.
“That's been really powerful and has helped us really speak in a more data-driven way into how to uplift conversion rate.”
A Shopify migration. Thousands of SKUs. +30% on Gemini.
SOZO ran a Magento 2 to Shopify migration for one of their SME clients. Scope: thousands of SKUs, hundreds of collections. Migrations like this are high-stakes by default. In traditional SEO, a botched migration tanks organic visibility for months. The same risk now applies to AI search, and the tools to measure it have lagged behind.
SOZO used Writesonic across the migration timeline. The team established a pre-launch baseline of AI visibility across every targeted prompt, identified which pages drove the most discoverability, and prioritised those pages in the migration. Sentiment monitoring ran before and after to confirm AI’s description of the brand didn’t worsen. Post-launch, the same dashboard measured the lift across every major AI platform.
Within 30 days of launch:
• All AI platforms combined: +10% within 30 days
• Google Gemini specifically: +30% within 30 days of launch
“It helped give us clear strategic direction and to support the migration to ensure it was a success.”
Christian Goodrich, Head of SEO & AI Search at SOZOSOZO published their own case study on the migration with screenshots and video documenting the results.
What “enterprise partnership” actually means.
For SOZO, the platform is half the story. The relationship is the other half.
The dedicated Slack channel with the Writesonic team has been the most practically useful piece. When Christian’s team needs a fast answer for a client, the Writesonic team replies in the channel without a support ticket queue or an email chain.
“Just having you guys available for when our team have any urgencies or questions, as an enterprise partner, that's been really valuable to us. We can pass that value onto our clients.”
The two teams have met in person at brightonSEO. The working relationship runs across sales, customer success, and support, and Christian’s read on it has been consistent.
“We've always had a fantastic experience with the Writesonic team. We've got to know certain team members really well and networked with them at brightonSEO and met them in person, which was great.”
The next problem to solve: attribution.
Christian was direct about what AI search measurement still hasn’t cracked. Most users interacting with AI platforms don’t click through, so traditional attribution models break.
“A lot of clients are asking: how does this impact our revenue? How does this impact our leads?”
Christian Goodrich, Head of SEO & AI Search at SOZOWhat SOZO can show is the direction of travel. Branded search up 17% year on year. Attributed organic revenue climbing. Return on search investment at 26x, up 65%. Strip out homepage traffic and that return is up 96%, non-brand demand growing rather than brand traffic alone.
SOZO treats AI search as the top of that funnel, the discovery layer that shapes a buyer before they search a brand by name or click a link. The harder question is no longer whether AI visibility creates commercial value. It is how to draw a precise line from a single AI mention to the revenue it influenced. Christian sees that as an industry-wide gap, not a Writesonic one.
He flagged two ways forward: product features that connect AI discoverability to revenue and lead outcomes, and an agency-focused content guide for the ROI conversations clients are starting to push for. Both are on the Writesonic roadmap.
