LLM Indexing: Get Your Site Into ChatGPT and AI Search

The problem: AI assistants can't cite what they can't find

LLM Indexing is the process of getting your pages into the index that Language Learning Models like ChatGPT use to answer questions. When a page is in that index, it can show up in the responses the chatbot generates. When it isn't, it can't.

Here's the part most people miss: ChatGPT and Perplexity don't maintain their own crawl of the entire web for live answers. They rely on Bing's index for search. So a page that's missing from Bing is effectively invisible to those AI assistants, no matter how good the content is. You can rank in Google and still be a ghost in ChatGPT if Bing never indexed you.

Most founders set up Google Search Console and forget Bing entirely. That gap is exactly where AI visibility leaks out.

How LLM indexing actually works, step by step

1. 1

   An AI assistant gets a question

   Someone asks ChatGPT or Perplexity about your topic. To answer with fresh, factual info, the assistant runs a web search behind the scenes instead of relying only on its training data.

2. 2

   That search hits a real search index

   ChatGPT and Perplexity don't crawl the whole web themselves. They lean on Bing's search index for live results. If a page isn't in Bing, it isn't in the pool the assistant pulls from.

3. 3

   Pages get ranked and quoted

   The assistant pulls a handful of results, reads them, and writes an answer that cites or paraphrases them. Pages that are indexed and relevant get surfaced. Everything else stays invisible.

4. 4

   Indexing is the gate

   You can't be cited if you can't be found. Getting your pages into Bing's index is the prerequisite for showing up in AI search, the same way Google indexing is the prerequisite for classic search.

What IndexMachine does about it

IndexMachine handles the Bing side of LLM indexing for you, on autopilot, so your content actually reaches the index ChatGPT and Perplexity read from. It runs daily and you don't touch it.

• ·Submits your new and updated URLs to Bing Webmaster Tools (the index behind ChatGPT and Perplexity) and to Google's official Search Console Indexing API, automatically every day.
• ·Monitors your sitemap daily and picks up fresh pages the moment you publish, so AI crawlers learn about them fast.
• ·Auto-detects pages that fell out of the index and re-submits them, so you don't quietly disappear from AI answers over time.
• ·Alerts you on 404s and broken pages, and sends a daily indexing report so you always know what's in and what's not.
• ·Runs every domain you own from one multi-domain dashboard, using read-only OAuth access to Search Console. 100% white-hat, no black-hat tricks.

On lifetime plans you get up to 20 URLs/day for Google and 200 URLs/day for other engines. On subscription it's unlimited sites and pages, roughly 600 pages/month for Google and 6,000 pages/month for the other engines.

Who this is for

LLM indexing matters most if your audience has already started asking AI assistants instead of search bars. That's most of them now.

• ·Indie hackers and SaaS founders who want their product pages and docs cited when someone asks ChatGPT for a tool.
• ·Content creators and bloggers optimizing for AI visibility, not just classic Google rankings.
• ·Programmatic SEO operators with thousands of pages that need to reach Bing, not just Google, to be useful to AI search.
• ·Agencies and solopreneurs managing multiple sites who don't want to babysit Bing Webmaster Tools by hand.
