Early Yahoo. #1 ads books. 800 universities. And no read on AI search.
Dennis Yu was at Yahoo in its early years and helped train the people who later built ad products at Google and Facebook. He retired twenty years ago and spent the next two decades coaching agencies, writing books with Perry Marshall (the #1 bestselling titles on Google Ads, Facebook Ads, and TikTok, 800,000 copies sold across the catalog), and building BlitzMetrics into a digital marketing agency and education business. 800 universities run BlitzMetrics training. Their free ebook site pulls roughly 500,000 visits a day.
The team had mastered every traditional discovery channel. Then ChatGPT changed how their buyers research products. The existing analytics had nothing to say about it.
“We want to show up more in ChatGPT. We know people are going to be having conversations with ChatGPT, and that'll partially displace search, not completely.”
Dennis Yu, Founder of BlitzMetricsAI search was changing how buyers researched. Existing analytics had nothing to show.
Buyers were going to ChatGPT before they searched on Google. Dennis had licensed data from Ahrefs, SEMrush, and a handful of other SEO tools, but none of them measured AI search well. Market share inside ChatGPT, citation patterns across LLMs, the bots crawling the site, the prompts BlitzMetrics was missing. None of it was visible in the existing stack.
The team needed a tool that sat alongside Google Analytics, their existing search infrastructure, and their ad stack. An advisory layer specifically for AI search.
Writesonic reached out. BlitzMetrics signed up.
Writesonic approached BlitzMetrics for a partnership. Dennis ran the platform on blitzmetrics.com and used it as the AI-search advisory feed alongside Google Analytics, his Infusionsoft data, and his Ahrefs licensing.
He's shown the Writesonic dashboard at twenty-some industry conferences. The framing he uses with audiences: AI search demands its own measurement layer, because no other tool tells you which bots are crawling your site, what answers you're showing up in, where competitors are mentioned and you're not, and which prompts to chase next.
“Writesonic is best used as an extension, as a multiplier of what you already have.”
The Content Factory: produce, process, post, promote.
BlitzMetrics runs a four-stage workflow Dennis calls the Content Factory.
Produce. Mostly podcasts. The team interviews subject matter experts who already rank for the queries BlitzMetrics is targeting. Roger Wakefield, the most-followed plumber online. A cosmetic dentist for high-end clientele. A SaaS founder. A landscaper. Each interview batches dozens of questions in one session.
Process. Descript handles the video editing. Writesonic handles the AI search advisory: which prompts BlitzMetrics is missing, which competitor citations they could earn, which content gaps to fill. Writesonic feeds the editorial brief.
Post. Each podcast becomes articles, video clips, and social posts. Distribution runs across Facebook, LinkedIn, YouTube, and the BlitzMetrics network of sites.
Promote. Paid ads against the new content drive Chrome clickstream signals, which then feed Google's organic rankings. The cycle compounds.
The Content Factory was working before Writesonic. Adding Writesonic gave BlitzMetrics a continuous feed of AI-specific topics they'd been missing.
Dennis's GEO insight: ChatGPT recognizes individual experts.
Dennis's sharpest GEO insight from running the Content Factory: AI engines weight authorship more than Google's link graph does.
When BlitzMetrics interviews a subject matter expert with their own ChatGPT footprint (Roger Wakefield in plumbing, for example), every published article and clip carries that expert's name. ChatGPT, Gemini, and Claude already know the expert. The next time a user asks ChatGPT a plumbing question, the system has both the answer and the trusted voice attached to it.
That's what Google's E-E-A-T tries to encode: experience, expertise, authoritativeness, trustworthiness. AI engines weight it harder than traditional search ever did.

“AI engines care more about who's saying it. As opposed to building a knowledge graph.”
Goals, Content, Targeting (GCT) is the framework BlitzMetrics layers on top. A prompt alone doesn't reveal who's asking. A cosmetic dentist targeting a successful entrepreneur needs different content than the same dentist trying to answer a price-shopper's query. GCT keeps the persona in scope, not just the prompt.
$200K. 3x human traffic. From AI search alone.
Three months in:
• Weekly AI bot visits: 3,500 → 5,000 (+43%)
• Weekly human visitors from AI: Tripled
• Monthly AI-influenced visits: ~50,000 on blitzmetrics.com
• New clients sourced from AI search: 2 × $100K+ ACV
Dennis is candid about the bot-visit metric. The more BlitzMetrics queries ChatGPT, the more it visits their own site, so bot counts can self-inflate. Human visitors are the cleaner read. Those tripled. The human visitors converted: two new clients, each worth $100,000 or more, both attributing their discovery of BlitzMetrics to AI-driven recommendations.
“We've had a couple of clients come in worth $100,000 each. The investment in time using Writesonic has definitely given us more clients.”
Dennis Yu, Founder of BlitzMetricsDennis's takeaway: every serious site needs AI visibility tracking.
For BlitzMetrics, AI search is now a tracked channel alongside Google Analytics, Infusionsoft, and Ahrefs. Dennis runs Writesonic across three sites today and is moving more onto the platform as he scales the Content Factory.
His advice to agencies and content marketers comes from someone who built search engines for a living before he ran an agency: don't talk about AI search until you've earned the right by doing it yourself.
“If you have not done it yourself, you can't talk about it. We need to stay on top of AI. If we're not direct practitioners ourselves, then it doesn't count.”
