About Error code: 403
from our crawl and measurement
Error code: 403 is a business whose own site puts it this way: "We’ve mapped thousands of public transit routes all over the world, but for some reason, we can’t find this webpage." As far as answer engines are concerned it may as well not exist yet: 2.6 out of 10.
The gap is on the page itself: the site is missing structured data describing the business, an llms.txt file, a sitemap, which are the first things an answer engine looks for.

Why your brand doesn't show up in ChatGPT answers (and how to fix it)
ChatGPT doesn't crawl the web like Google does. When someone asks Claude about the best project management tools, the model isn't searching your website in real-time. It's pulling from training data that stopped months or years ago.
