Many AI crawlers read the HTML a page sends and nothing more. If your VIN and price arrive later, they may never see them.
Two kinds of page, one URL
Some dealer websites send a nearly empty page and fill in the vehicle with JavaScript after it loads. A shopper in a browser never notices. A crawler that reads only the HTML it was sent sees a page with no car on it.
Search engines have long run JavaScript. Many AI crawlers and the tools assistants use to fetch a page while answering a question don't, or don't wait for it. For them, what's in the first response is all there is.
How to check your own site
Open one of your vehicle pages and view its source (not the inspector, the raw source). Search it for:
- The 17-character VIN.
- The price.
- The year, make and model as text, not only in an image.
What good looks like
Every fact a shopper would ask about is in the HTML, alongside structured data (schema.org Vehicle and Offer) that states the same facts in a form machines read reliably. Our free site check tests exactly this on one of your vehicle pages and shows you what it found.
Virtual Lot pages are built this way from the start: complete in the first response, tested with a script that fetches each page type without running any JavaScript.
