Clients started asking a question SOZO couldn't answer.
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's worked in AI-driven search for nine years.
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. SOZO had no way to measure where their clients stood.
“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 AI Search & SEO 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 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.
Brighton SEO. A demo. An enterprise partnership.
SOZO found Writesonic through their own research and conversations at Brighton SEO, 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% in the days immediately post-launch
“It helped give us clear strategic direction and to support the migration to ensure it was a success.”
Christian Goodrich, Head of AI Search & SEO 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 Brighton SEO. 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 Brighton SEO 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. Clients want to know how AI visibility translates into revenue and leads. Most users interacting with AI platforms don't click through to brand sites the way they would from a Google result, so traditional attribution models break.
SOZO currently positions AI search as a top-of-funnel discovery channel that influences brand consideration earlier in the buying journey. Clients want a clearer line from that influence to pipeline.
“A lot of clients are asking: how does this impact our revenue? How does this impact our leads?”
Christian Goodrich, Head of AI Search & SEO at SOZOChristian sees this as an industry-wide gap, not a Writesonic-specific 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.
