Brainz x Hulken: AI-Powered SEO That Blew Past Every Goal

INTRO

About the Client

Hulken is the number one eCommerce brand for rolling tote bags, more commonly known as schlepping bags. The bags come in a range of sizes and colours, and up until 2024, Hulken ran as a single-product store. Since then, the brand has broadened its catalogue to include laptop sleeves, carry-on bags, and a growing line of accessories. Hulken brought in Brainz because we are focused on AI-first SEO, to grow their organic search presence, shift the balance between branded and non-branded traffic, and start capturing the LLM audience that most brands were still completely ignoring.

The Problem

When Brainz took on the Hulken account, the brand had a very specific problem that was quietly limiting its growth. Almost all of its organic search traffic was branded, meaning that with 98 non-branded keywords compared to 3,035 branded ones, the site was essentially only visible to people who already knew the Hulken name. That kind of dependency leaves a brand exposed, because it forecloses any meaningful opportunity to reach new audiences who are searching for products like theirs but have never heard of them. Hulken also had minimal visibility in Google’s AI Overviews and no real presence across LLMs like ChatGPT, Perplexity, and Gemini. At just 25 LLM sessions per month in attributable LLM revenue, this channel had barely been touched, which meant there was significant untapped potential sitting there waiting to be activated.

The work that was done

Goals & Targets

Hulken came in with ambitious targets across two core areas, and what Brainz delivered ended up exceeding both of them by a significant margin.

Branded/Non-Branded Keyword Ratio

Google Visibility (Keywords & Impressions)

 

The Strategy: Four Pillars

Brainz structured the campaign around four interconnected pillars, with each one designed to feed into and strengthen the others rather than operate in isolation.

1. AI-Driven Foundation

Rather than relying on existing platforms, Brainz built our own proprietary AI infrastructure from the ground up for this campaign, which gave the team a level of precision and visibility that generic tools simply couldn’t offer. The core components were:

    • Brainz AI, a custom tracking and auditing tool built to monitor LLM visibility, track brand mentions along with their sentiment, benchmark performance against competitors, and surface the kind of actionable recommendations that actually move the needle.

    • AIO Re Ranker Tool, built using insights from Google patents and validated against Google warehouse documentation leaks. The tool applies a mathematical framework to shape content in the format that Google’s AI Overviews consistently prefer to cite.

    • Internal Content Machine, a multi-step content production platform that generates briefs and full articles in line with Hulken’s brand voice, tone, and messaging. All content produced through it incorporates entity-based writing, semantic compression, and answer-first structures built for AI consumption.

    • Custom GPTs for Content Briefs, three specialised models built for distinct stages of the brief process: one to extract AI Overview consensus, one to analyse competitor SERP coverage, and one to pull customer pain points from support tickets and sales transcripts and turn them into content headers.

2. Content for the Right Audience

The team moved well beyond generic top-of-funnel content creation, recognising that pulling visitors to the site was only half the job. The content machine was used to produce material that genuinely connected with the right audience at multiple stages of the purchase journey, covering product use cases, feature deep-dives, and launch-support content that gave new visitors a real reason to stay and buy.

Keyword strategy was rebuilt around high-value intent rather than raw search volume, which meant every piece of content had a clear path to both discoverability and conversion rather than just chasing traffic that would bounce.

3. Trust-Building Elements

The Brainz AI tool flagged gaps in Hulken’s credibility signals that were quietly suppressing conversions even as traffic continued to climb. The team responded by redesigning the About Us page to tell a fuller story about the brand and its founders, and by adding customer review integrations across key product pages to build the kind of social proof that pushes hesitant shoppers over the line.


4. Website Redesign with SEO + UX in Mind

The existing Hulken website had become a conversion bottleneck, because traffic was growing steadily but revenue momentum wasn’t keeping pace. Brainz led a full site redesign that addressed both technical SEO and user experience at the same time, because the two are too closely linked to treat separately. That work covered:

    • Meta tags, structured data, and a topical cluster-based internal linking structure to give Google a clearer picture of site architecture and content relationships.

    • A full review of menu structure, CTAs, footer layout, and blog templates to make the site easier to navigate and more persuasive at key decision points.

    • Performance improvements across product pages, including removing or reworking animated elements that were creating layout shift and dragging down load times.

Results

The results across the board told a compelling story. Keyword rankings climbed sharply across both traditional search and LLM platforms, AI Overview visibility started converting into real purchase-intent traffic rather than passive impressions, and blog content that had previously been sitting at the top of the funnel began driving meaningful revenue as LLMs picked it up as a reference source and funnelled readers toward product pages. The site redesign lifted organic traffic sitewide, brought in a strong wave of new users while also improving retention of existing ones, and pushed conversion rates higher month-on-month, with December delivering a 15% revenue gain on top of what had already been the brand’s strongest Black Friday on record. ChatGPT-attributed revenue grew significantly, LLM session volume multiplied several times over, and the engagement numbers from blog content showed that the audience arriving through these channels was genuinely interested, not just passing through.

In Summary

The numbers speak for themselves, but two things make this campaign genuinely stand out from a typical SEO success story. Proprietary AI Tooling at Agency Scale Most agencies were still struggling to track LLM-driven traffic at all when this campaign was underway, yet Brainz had already built a complete ecosystem to audit, optimise, and measure performance across Google, AI Overviews, and LLMs at the same time. The Brainz AI visibility tool, AIO Re Ranker, Content Machine, and custom GPTs weren’t brought in from outside vendors or bolted together from existing products. They were purpose-built, which meant the team could act on real data and iterate quickly rather than waiting for platforms to catch up with where search was actually heading. Measurable LLM Revenue Attribution This campaign is one of very few that can point to clear, attributable revenue coming directly from LLM channels. While most brands are still at the stage of wondering whether their LLM presence matters, Hulken had the tracking infrastructure to prove it, and the numbers showed that LLM optimisation drives real purchase revenue, not just impressions or sessions that disappear without converting.
