In memory of Warren Blumberg, my boss at Kelsey National. He was right about the homepage.
On July 30, 1995, healthinsurance.com and dentalinsurance.com went into the .com registry on the same day. Registration was free. The National Science Foundation was still paying Network Solutions to process new names, and the $100 fee for a two-year registration didn’t start until September 14. Forty-six days.
On July 29, 2019, one day short of 24 years later, a public insurance distributor called Health Insurance Innovations signed a stock purchase agreement for “a corporation, which owned and operated HealthInsurance.com.” Its cash flow statement for 2019 has a single line called “Acquisition of domain name.” The amount is $8,133,000.
The filings don’t name the seller. Kentucky’s business registry still carries an inactive record for HealthInsurance.com, Inc., a Delaware corporation registered there in 2000, with its principal office at 3030 South Bundy Drive in Los Angeles.
I know that address. In 2004 it was in my email signature, under “Kelsey National Corporation” and above links to both sites.
Health Insurance Innovations renamed itself Benefytt Technologies and filed for Chapter 11 on May 23, 2023. HealthInsurance.com now calls itself “a site owned and operated by Health Insurance Associates, LLC,” an agency in Daytona Beach. DentalInsurance.com is still Kelsey’s. The footer says so, and a 2023 press release credits Mark Kelsey with launching it in 2001 and calls it “the pioneer of comparing dental plans from different insurers within a single online marketplace.”
Warren Wanted the Big Red Box
Kelsey National goes back to 1964. When I worked there it was a family business, an insurance marketer and third-party administrator run by Mark Kelsey. I was there about a year. I wrote DentalInsurance.com in Classic ASP and built the reporting in .NET, and the company ran an affiliate network that sent traffic to both the health and the dental sites.
The best thing about the job was that it was close to Tito’s Tacos on Washington Place. The worst was the drive home to the Valley. The 405 through the Sepulveda Pass at rush hour was bad enough that some nights I killed time at the Century City mall until it cleared.
Warren Blumberg was my boss. He was a classic salesman. He used to sleep in his office, so whenever I walked in he looked like he had just gotten up. He also knew exactly where the money came from.
On Friday, March 5, 2004, I sent him a homepage redesign. My friend Lowell had put it together in about twenty minutes in Photoshop, because I’d asked him to keep it light and keep the design to a minimum. My email admitted that I’d forgotten to tell him no teeth. It also said I didn’t think I could talk him into a big bulky red box to match HealthInsurance.com.
Warren answered at 8:53 on Monday morning. The colors didn’t carry over from the new homepage to the comparison page. He didn’t like the black background behind the teeth, or the color of the logo. He wanted language that told individuals and families exactly where to enter their information to sign up, and he wanted Submit Express, the firm doing the site’s search optimization, to assure him the redesign wouldn’t affect its work. He closed with two sentences.
While you say this cannot be done the Kelsey way, we also cannot afford to make a mistake. This is a key driver of revenue for the company and a failure will be very, very costly.
He had his reasons. Google’s Florida update had landed on November 16, 2003, and knocked many small retailers and affiliate sites out of the rankings right before the holidays. Rankings didn’t settle until early 2004. Google itself was still five months from going public. A homepage change on what Warren called a key driver of revenue, less than four months after Florida, was a real risk, and he treated it like one.
I thought the big red box was ugly. Warren thought it was the business. Warren was right. Click “See Plans” on DentalInsurance.com today and you get a form that asks for a ZIP code, a county and a date of birth, with buttons to add a spouse and a child. Individuals and families, and exactly where to enter their information. Twenty-two years later, that’s still the page.
Warren died last year. I found out while I was putting this piece together, and it’s dedicated to him.
The Name Did the Selling for Twenty Years
A category .com cost nothing in July 1995, and for most of the next twenty years it paid like an annuity. Someone typed “dental insurance” into a search box, or straight into the address bar, and the exact match came up. They clicked. A quote form took it from there, and a carrier paid the commission.
That was the directory business. The site stood between people who needed a plan and the carriers who sold them, and it got paid for standing in the doorway. Some of that still works. Semrush estimates 189,600 visits in October 2026 and puts 35.3 percent of them at direct traffic, which for a name like this mostly means people typing it.
The rest is moving above the links. Pew Research Center tracked 900 American adults through 68,879 Google searches in March 2025. When an AI summary appeared, people clicked a traditional result on 8 percent of visits, against 15 percent without one. They clicked a link inside the summary 1 percent of the time. On 26 percent of the pages with a summary, they ended the browsing session right there, compared with 16 percent on pages without one.
Seer Interactive’s 2026 update covers 53 brands and 2.43 billion organic impressions. Organic click-through on queries with an AI Overview fell from 3.19 percent in January 2025 to 1.31 percent that December, then climbed back to 2.36 percent by February 2026. Per million informational impressions, Seer counted about 33,500 organic clicks when no AI Overview appeared, about 20,700 when the brand was cited inside one, and about 9,400 when it wasn’t. The query types a comparison site lives on are the ones most likely to get a summary. In Seer’s data, comparison queries triggered an AI Overview 95.4 percent of the time, and queries about price, cost or buying did 83.4 percent of the time.
Then Google made the summary the product. At I/O in May, it said AI Mode had passed one billion monthly users, made Gemini 3.5 Flash the default model worldwide, announced it was merging AI Overviews and AI Mode into a single experience, and declared that Search is entering “the era of Search agents.”
On October 12, I searched “dental insurance” from Las Vegas. The AI Overview says individual plans there typically cost “between $20 and $60 per month” and cites UnitedHealthcare for it. The rest of the answer leans on Delta Dental, Anthem, YouTube and a dental office in Summerlin. None of the citations I can see point to DentalInsurance.com.
DentalInsurance.com has a more specific number. Its Nevada statistics page, updated August 26, 2026, sampled 22 plans and found an average premium of $50.58 a month for a 35-year-old woman, from $12.95 at the low end to $89.00 at the high. Google went to the carriers anyway. The middleman got skipped by a machine that read the carriers’ pages and did the comparing itself.
The Comparison Table Is the Part That Dies
There are two standard reactions to numbers like these, and both are lazy. The first says directories are finished and there’s nothing to be done. The second sells a fix, usually some mix of llms.txt files, machine-readable feeds, content chopped into chunks and a dashboard that counts AI mentions.
Google answered the second one itself. Its guide to optimizing for generative AI search, last updated in July, says site owners don’t need new machine-readable files, AI text files or special markup to show up in its AI features, “as Google Search itself doesn’t use them.” Chunking content, rewriting it for AI and chasing inauthentic mentions are on the same list of things to skip. The AI features, in Google’s words, are “rooted in our core Search ranking and quality systems.”
What dies is the comparison table as a product. A model builds one in a second from the carriers’ own pages, which is exactly what the Las Vegas answer did. What survives is the part a model can’t do. It can’t hold an insurance license. It can’t get appointed to sell for a dozen carriers, put a licensed agent on the phone, or enroll anybody in anything. Kelsey has been in that business since 1964. Its homepage still leads with the word “compare.”
Somebody at Kelsey Is Already Working on This
DentalInsurance.com isn’t asleep. Its robots.txt opens with a header dated September 2026 that states a strategy in one line, “Allow search/retrieval bots, block training bots.” It points to a plan data feed, generated in April, that describes itself as “intended for AI search systems, aggregators, and structured data consumers.” The state statistics pages carry 2026 data drawn from 1,196 plan records. Somebody there is paying attention.
The traffic isn’t collapsing either, at least by Semrush’s estimate. Organic visits went from about 10,000 in September to 52,640 in October, and paid traffic went from nearly nothing to 17,670. Fall is open enrollment season for employer benefits and Medicare, and these are modeled estimates, so I wouldn’t build a forecast on one month.
The trouble is what the traffic is made of. The average visit lasts about a minute and touches 1.07 pages. The top keyword in the estimate is “ameritas provider portal,” 4,400 searches a month from people trying to log in to another company’s system for dentists. The site named DentalInsurance.com ranks 18th, on page two, for “dental insurance plans,” a phrase searched 74,000 times a month. It ranks first for its own name.
Then there’s the robots file. The strategy is sound. The file doesn’t carry it out.
Anthropic publishes three crawler names. ClaudeBot collects content that may be used for training, and Anthropic says restricting it signals that a site’s future content should be excluded from training data. Claude-SearchBot indexes for search, and Claude-User fetches pages when a person asks Claude something. DentalInsurance.com lists ClaudeBot in its allowed group of “search/retrieval bots.” Under a comment that reads “Block Anthropic training crawler,” it blocks anthropic-ai, a name that isn’t on Anthropic’s current list. The two retrieval crawlers aren’t named at all, so they fall through to the default rules and get in anyway, which is fine. The training crawler is the one the file welcomes by name.
Google is subtler. The file blocks Google-Extended under the comment “Block Google AI training (Gemini).” Google’s crawler documentation says the same token also controls whether a site’s content can be used for grounding answers in the Gemini app, and that it has no effect on Google Search. So the site stays eligible for AI Overviews, where clicks are scarce, and opts out of being a source when somebody asks the Gemini app about dental plans. That may be the right trade. It should be a decision. The comment reads like a label.
A Feed Built for Machines Will Mislead Them
The plan feed is the more interesting mistake, because the idea behind it is right. The company has detailed data on 56 plans and wants machines to have it. Three things go wrong.
The robots file declares the feed as a sitemap. Google reads XML sitemaps, RSS and Atom feeds, and plain text lists of URLs, and a custom XML document built around a list of plans is none of those. Even if it were, Google’s AI guide says Search doesn’t use special machine-readable files.
The feed is also frozen. It says it was generated on April 9, 2026, and every plan I checked carries that same lastUpdated date. The quote engine on the same site prices plans by ZIP code and age on request, and the page for MetLife’s TakeAlong Dental HMO-Managed Care 245 shows $11.02 a month and an application for a November 1 effective date. The feed is a snapshot from the spring.
The third problem is the one a model will repeat. The feed defines planPays as the percentage the insurance plan pays. For HMO-style plans, the same field holds a flat copayment, and a copayment is what the member pays. So that MetLife HMO shows a crown at planPays “$245.” The member pays the $245. The same plan lists a cleaning at planPays “0%,” which by the feed’s own definition means the plan pays nothing for a cleaning. It means the member pays nothing. Guardian’s Managed DentalGuard is marked as covering implants, with details that read “No coverage.” Anthem’s Essential Choice Premier links to the page for Essential Choice Basic.
I build retrieval pipelines and MCP servers for a living. Retrieval quality is capped by the corpus, and no model upgrade fixes a field that means one thing for a PPO and the opposite for an HMO. A model grounded on this feed would tell a customer in Sacramento that MetLife pays $245 toward her crown, and it would cite DentalInsurance.com while it did. Either nobody reads the feed, or somebody reads it wrong.
What I’d Do With the Name
Start with the robots file, because it’s an afternoon. Name Claude-SearchBot and Claude-User in the allowed group, decide on purpose what to do about ClaudeBot, and drop the anthropic-ai line. Make the Google-Extended call with the Gemini app in mind, not a comment about training.
Next, rebuild the feed from the same database the plan pages use, every night, with a date that moves. Split the field. Plan pays goes in one column and member pays in another. Put “you pay” in front of the $245 on the plan page while you’re in there, and stop calling the file a sitemap. If other systems want the data, document it as an API.
The state pages need the most work. The Nevada statistics page from August says the average premium is $50.58 for a 35-year-old across 22 plans, then sends readers to the Nevada plans page for “actual Nevada plans and pricing.” That page says it was updated on October 6, 2023. It quotes 2023 sales data and a $43.99 average for a 33-year-old across 35 plans. Two averages for one state, three years apart, on one domain. A retrieval system has to pick one.
The best sentence on that old page starts with “Using 2023 sales data from DentalInsurance.com customers” and goes on to name the three most popular plans in Nevada. No carrier will publish that about its competitors, and no model can generate it. That is what Google means by non-commodity content. Google’s own example of the opposite is “7 Tips for First-Time Homebuyers,” and the Learning Center’s “What are Dental PPO Plans?” is the dental version. Publish the bestsellers by state every quarter. Publish what the call center hears, from the waiting periods that catch people off guard to the questions that come right before a purchase. Put the names of the agents who answer the phones on it.
Then video. Pew found YouTube among the three sources Google’s AI summaries cite most, along with Wikipedia and Reddit, and YouTube showed up more than once in the Las Vegas answer. Put licensed agents on camera answering the questions the phones get every day. That’s first-hand content, in the format the summaries already cite.
Measure it in Search Console’s Generative AI performance report, which Google built for exactly this, and stop grading the year on sessions. In Seer’s numbers, being cited inside the answer is worth more than twice the clicks of being skipped by it.
The bigger project is a door for the agents. Google says Search is entering the era of agents, and its own guide points site owners toward the Universal Commerce Protocol, which it says “will allow Search agents to do more.” In the Las Vegas answer, the machine went straight to the carriers. Kelsey’s pitch to the agents should be the one it made to people in 2001. A dozen carriers in one place, and a real price for your ZIP code. That means a quoting tool an assistant can call, one that takes a ZIP code, ages and needs and returns real plans with real premiums, and a handoff that puts a licensed agent on the line before anything gets signed.
I’ve shipped this pattern. At Prana Entertainment I built an autonomous customer service and payment agent that runs inside PCI scope, and the MCP plumbing was the small part of the job. The real work was deciding which steps a human has to own, writing that down, and logging every call the model makes. A dental quote server has the same shape, with one tool that quotes and another that opens an application and books a licensed agent. Insurance adds state rules, required disclosures and signatures. That friction is the moat. A model can summarize a dental plan. It can’t sell you one without a licensed company on the other end.
Tito’s Never Needed a Directory
Tito’s Tacos has been on Washington Place since 1959. One location, hard-shell shredded beef tacos, a line at lunch. Nobody needs a summary of a taco. People drive there.
DentalInsurance.com has the name, the licenses, the carriers and a homepage that still does what Warren asked for in 2004. It should be where people finish buying dental insurance. Right now it’s built for where they start looking.
If Mark Kelsey or anyone on his team wants to go through any of this, I’m easy to find. I still miss the tacos.
