Dealer sites turn away an AI crawler
At least one refused — most often OAI-SearchBot, ChatGPT-User, Claude-User.
Your fixAllow AI crawlers in your site’s firewall or bot settings — usually a single setting.
VIN Index publishes your inventory as pages AI can read and cite — straight from your feed, with no change to your website — and every enquiry goes to you. The first dealers here to do it are competing with almost no one.
Website figures: the newest VIN Index AI-readiness check of every Sioux City area dealership website we track (18 sites, Oct 16–Oct 16) — wider than the 12 dealerships on the leaderboard, which are the ones we match by name in answers. Each card counts only the sites where that particular check gave a clear result, so each has its own total. Sites may have changed since. Totals across dealerships, never about one.

The dealership’s own tracked questions, not this page’s sample, and none names a dealership. “Named” compares the same questions and assistants in its first ten days of checks (Jul 18) and its latest ten (Sep 28). Citation counts are from our checks, not buyer traffic. One dealership’s result, not a guarantee.

Where the answers send buyers
Which websites the 215 answers pointed buyers to. The marketplaces publish a price and a payment for every car in one place — exactly what a budget question asks for — so that’s where the answers go.
85%
of answers cite a listing marketplace
31%
of answers cite a local dealership’s own website
Linking isn’t recommending: an answer can list a dealer’s page among its sources — any dealer’s, not only the 12 on the leaderboard — without naming that dealer to the buyer. That’s why this is higher than the 29% of answers that name one.

How we measured this
One saved sample: 12 questions asked in each of Sioux City, Spirit Lake, Odebolt, Spencer, Storm Lake, Le Mars, answered by ChatGPT, Gemini and Perplexity with web search on October 16, 2026. Five monthly-payment, five cash-budget and two dealer-discovery questions per location. No question names a dealership. Answers in the consumer apps can differ, and a new sample can differ from this one.
Every answer figure uses the same 215 successful answers. “Name a local dealership” means the answer text names one of the 12 dealerships we track in this area, identified from their own websites; that list is not every dealer in the area. “Cite a marketplace” means the answer’s sources include a listing marketplace or national online retailer.
These counts describe what the answers said. They are not shopper traffic, sales, or a dealership’s position within an answer, and they do not show why any dealership was or wasn’t named. Differences between individual areas rest on 36 answers each and are not reported.
