Nook
How Nook Built an AI-Citation Footprint in a Brutally Contested Category
After a GEO sprint with BrandViz.AI, Nook went from a site AI crawlers couldn’t render to being cited at over half the rate of Calm, a category leader with a decade of content and household-name recognition, across ChatGPT, Claude, Gemini, and Perplexity. On Claude, Nook passed Insight Timer, Smiling Mind, and MindMum. The same foundation also got Nook indexed on Google for the first time.
“LLMs are probably one of the easiest and most effective ways for a new brand to build name recognition against larger competitors. It was surprisingly quick for Nook to start appearing in the same responses as Calm and Headspace. Users are more likely to explore multiple suggestions from an LLM compared to Google, where the first result tends to capture most of the traffic.
Users generally don’t trust companies calling themselves ‘the best’, but when an LLM mentions your brand alongside established competitors, it creates instant credibility with significantly less effort.
Day-to-day, the support went above and beyond, especially around integrating the content and helping guide the strategy. The content itself was good quality and gave us a strong starting point.
For founders whose product is something people compare or research before buying, GEO can provide a huge advantage, particularly for comparison-style prompts where ranking top three on Google can be an extremely long and difficult process.”
60 days. By the numbers.
| Metric | Before the sprint | After the sprint |
|---|---|---|
| Own-site AI citations | none | working footprint |
| Citation share across all models | 0% | 6.3% (vs Calm 11.5%) |
| Claude mention rate | 0.5% | 14.4% |
| Competitive Intelligence queries | 4.2% | 16.2% |
| Sleep Support mention rate | not present | 14% |
| Sleep Support citation rate* | not present | 12% |
| Google Search visibility | not indexed | indexed, clicks flowing |
Baseline: March 9, 2026. Final report: April 27, 2026. Tracked across hundreds of buyer queries every week for the duration of the sprint.
* Citation rate - out of every 100 relevant sleep-support questions, Nook’s own website was used as a cited source roughly 12 times by the end of the sprint, from zero at baseline.
Google indexed Nook for the first time during the sprint
Before the sprint, Nook’s site wasn’t indexed on Google when you searched the brand name. By the end, it was indexed, ranking, and receiving direct organic clicks, a compounding side effect of the same GEO foundation and content work, at no additional cost.
Who Nook is
Nook is built by Dali and Kat Häusler, a husband-and-wife team and the parents of a toddler who, in their words, “thinks sleep is optional.” Dali is a principal engineer of ten years; Kat handles the meditation content and the voice of the brand. Nook is the app they wish had existed when their daughter was born: short, mom-specific guided meditations for the moments no one warns you about. It launched in 2025, built between work, parenting, and nap times.
By early 2026, Nook had real traction: top of the US App Store’s Mom Wellbeing category, an active reviewer base, and a small portfolio of utility apps Dali ran alongside Nook to keep the lights on.
Why Nook decided to run a GEO sprint
Dali had noticed something specific in his download analytics for those utility apps: users finding them were arriving from ChatGPT. The behaviour was quiet but consistent, and it implied a channel he wasn’t measuring. The question that followed was the obvious one: if it’s working for the utility apps, can it work for Nook?
“Before the sprint, AI visibility wasn't really on our radar. After seeing some of our other apps begin receiving downloads from ChatGPT, we became interested in whether Nook could also start appearing in top-of-funnel prompts and recommendations.”
Dali Häusler, Co-Founder, Nook
What was Nook’s AI visibility before the sprint?
Before the BrandViz.AI sprint began on March 9, 2026, Nook had zero own-site AI citations across ChatGPT, Claude, Gemini, and Perplexity. In over a thousand responses to category-relevant questions, Nook’s website was used as a source exactly zero times, and most models could not identify the brand at all when asked directly.
Every existing mention came from somewhere else: the App Store, third-party listicles, competitor pages. The answers to every “best meditation app for moms” query came from elsewhere. Calm and Headspace dominated. Insight Timer, Smiling Mind, and the mom-specific tier of MamaZen and Mindful Mamas filled in the rest. Nook’s own website: zero citations in the baseline report.
The site rendered fine for human visitors but was effectively invisible to AI crawlers. The only reason JavaScript was on the site at all was a runtime translation layer that swapped UK spelling (“mum”) for US spelling (“mom”) depending on visitor region. Crawlers, which don’t execute JavaScript, never saw a coherent page.
The state Nook arrived in was an early-stage app with a real product and an active user base, but no presence in AI search.
How BrandViz.AI ran the sprint
BrandViz.AI ran a 60-day GEO sprint for Nook across three workstreams: fix the technical foundation so AI crawlers could read the site, run a broad first content batch to map which queries were realistically winnable in a category dominated by Calm and Headspace, then build specialist comparison and segment pages against the queries the data identified as capturable.
Technical foundation - so AI crawlers could read the site at all
In week one, BrandViz audited Nook’s site and identified the core problem: a JavaScript translation layer that swapped UK and US spelling at runtime was making the pages invisible to AI crawlers.Every page was also missing the basic metadata models need to identify and contextualise a brand.
BrandViz re-architected the site for proper server-side rendering, added clean metadata across every page, scaffolded the Nook journal, and got Nook listed on the search indexes that feed the AI models. By the end of week two, every model could identify Nook correctly when asked directly. That foundation was what made everything else possible.
Content exploration - to map the category
The first batch of articles went broad: top-of-funnel pieces on overwhelm, guilt, burnout, the mental load. Some of those articles are excellent and remain on Nook’s journal as resources for readers. They were also doing strategic work behind the scenes, generating the citation data BrandViz needed to see which queries in this category were realistically capturable and which weren’t.
Had a quick look today. Looks great.
I really like that it has the references and the studies. That's great.
The signal was clear by week three. In a category dominated by Calm and Headspace at this scale, AI models answer top-of-funnel queries either from their own training data or from clinical sites and global incumbents. That insight defined what came next.
Specialisation and capture - the pages AI now cites
Comparison pages built against the queries the data said were winnable, plus targeted pieces for Nook’s strongest service area (sleep support), and a strategic listicle positioning Nook within the broader category.
By the end of the sprint, the pages BrandViz built for the comparison strategy were the pages AI was using to answer those queries.Each page was built for a specific query a buyer types into ChatGPT or Claude when she’s already comparing options.
“It became very apparent early on, through competitor analysis, that broad top-funnel rankings would be extremely difficult to achieve. Instead of chasing an unachievable goal, we pivoted toward areas where the data showed there was actual opportunity.”
Dali Häusler, Co-Founder, Nook
Which pages drove the most AI citations?
By the end of the sprint, the comparison and segment pages BrandViz built were the pages AI models were using to answer buyer-evaluation queries about meditation apps for moms. The Nook homepage shows up too, but it does the lightest work; structured, targeted pages outperform the homepage every time.

For early-stage founders without a fully defined brand voice, the content provides a starting point to iterate on rather than a fixed deliverable.
How do you get cited beyond your own website?
Off-site citations are the next layer of GEO. BrandViz mapped the publishers AI models cite most often when answering “best meditation app for moms” queries. Dali wanted the full list to work from and messaged David asking for an expanded export with selectable links. BrandViz shipped the export feature the same day.
Awesome that's perfect mate thanks for that.
Each new third-party mention compounds the citation footprint, because AI models weight what other sites say about a brand more than what the brand says about itself. The map turned the sprint into a strategy Nook could keep extending on its own.
“I've been reaching out about ten a day and I've had a few come back. A few said they'd start changing them, which is awesome.”
Dali Häusler, Co-Founder, Nook
Where Nook ranks after the sprint
By April 27, on Claude, Nook was ahead of Insight Timer, MindMum, Smiling Mind, Peanut, and Mumsly: half the tracked field. MamaZen and Mindful Mamas remain ahead in the mom-specific tier; Calm and Headspace remain dominant overall. What’s different is that Nook is now in the hierarchy, present in the conversation when buyers are actively comparing options.
Across all four models combined, Nook’s citation share reached 6.3%, more than half of Calm’s 11.5%. Calm has a decade of content, a billion-dollar valuation, and brand recognition in every household. After 60 days, Nook is being cited by AI at more than half Calm’s rate.
In direct buyer-evaluation queries (such as “What’s the best meditation app for a sleep-deprived mom?”), Nook now appears consistently across all four models. In Sleep Support specifically, Nook’s strongest service area, the brand reaches a 14% mention rate and a 12% citation rate. When someone asks about apps for moms with sleep issues, Nook is part of the answer.
Final-day citation share - April 27, 2026
Nook reached 6.3% citation share across all four models, more than half of Calm’s 11.5%. MamaZen leads the mom-specific tier at 13.4%; Headspace sits at 5.2%.
Smiling Mind (1.2%), Mindful Mamas (2.7%), Insight Timer (3.9%), MindMum (4.8%), and Peanut (0.0%) all sit below Nook in the final report - the bottom half of the tracked field that Nook overtook during the sprint.
The two answers don’t look alike. ChatGPT splits the response into tiers and places Nook in a “mom-focused sleep support” group alongside The Peaceful Sleeper and Beacon Postpartum, separated from clinical CBT-I options. Claude returns a single ranked list with Nook at the top, ahead of Mindful Mamas, Calm, and Insight Timer. What matters is that Nook appears in both - across different models, different query phrasings, and different response structures. That’s the difference between a one-off citation and a real footprint.
AI responses are non-deterministic - no two answers are identical. These screenshots were captured during the sprint period. The visibility metrics above reflect aggregated results across hundreds of queries, which is a more reliable signal than any single response.
How the sprint also got Nook indexed on Google
Nook’s website wasn’t appearing on Google when you searched the brand name before the sprint. By the end, it was indexed, ranking, and starting to receive direct organic clicks.
“From what I understand now, SEO practices are essentially the foundation of GEO. Whether you're ranking your own website for prompt-related searches or getting your brand mentioned on websites that already rank for those searches, the principles overlap heavily. GEO and SEO are very closely connected, but GEO feels more accessible for smaller brands because you don't necessarily need to rank in the top three search results.”
Dali Häusler, Co-Founder, Nook
For small brands going up against entrenched competitors, that asymmetry of being one of the credible options without needing to rank #1 is the entire game.
Search ranking compounds slowly. Three to six months is the typical horizon for a young domain to start ranking competitively. Nook is at the beginning of that curve, with the foundation in place to compound over time, at no extra cost beyond the GEO work that was already paid for.
Is GEO worth it in a contested category?
GEO is worth it in a contested category when three conditions are true: the product solves a clearly defined problem, buyers compare options before purchasing, and there is practical-intent language buyers already use to describe the problem. Nook met all three, which is why a 60-day sprint moved citation share from 0% to 6.3% in a category dominated by Calm and Headspace.
Dali had a related observation from running his other apps:
“Users generally need to prompt with practical intent for apps to be recommended. For example, prompts like 'How do I track contractions?' performed much better than broader emotional prompts like 'I'm scared of birth.'”
Dali Häusler, Co-Founder, Nook
This is why Problem Recognition queries, the early-stage “why am I feeling like this?” questions, don’t really get app recommendations from any provider in the category, including Nook. AI models reserve app recommendations for queries with explicit utility intent. They answer emotional prompts with emotional advice. The implication is direct: build for the utility-intent queries and stop chasing the emotional ones.
Dali’s broader read on which categories GEO works best in:
“GEO really shines in specific situations. If your product is something people naturally compare or research before purchasing, such as B2B software, high-price purchases, or highly defined utility products, GEO can provide a huge advantage. It works particularly well for comparison-style prompts because ranking top three organically in Google can be an extremely long and difficult process.”
Dali Häusler, Co-Founder, Nook
“We also noticed that LLMs seem very attracted to repeated practical information online. If your product solves a clearly defined problem and people commonly mention using apps to solve that problem, you have a much higher chance of appearing in results.”
Dali Häusler, Co-Founder, Nook
Those three conditions are the test for whether GEO will work for your category. The work is identifying which queries are capturable and building the specific pages that capture them. A sprint will tell you in 30 days.
Is your category dominated by a few household names?
Dali knew Nook couldn’t out-spend Calm or Headspace on brand. What he could do was get cited alongside them when a buyer asked an AI which app to try. That changed the conversation from “Who’s the biggest?” to “Which one is right for me?” - a question Nook is built to win.
94% of B2B buyers use AI during their purchase journey, and consumer buyers are catching up fast. In any given category, just five brands capture 80% of all AI-generated responses. If your product is something people compare or research before buying, one of those five spots is worth fighting for.
