How to see phantom AI traffic on your Ghost site, and turn the best of those made-up URLs into real posts or redirects. - Author: Michal Wlosik - Tags: Guides, SEO Ask ChatGPT about your niche and it may recommend your site, with a link. Sometimes the link goes to a page you never wrote. The URL looks right, follows your site's pattern, even has a sensible slug like `/blog/ghost-pricing-2026/`. The visitor clicks, lands on your 404 page, and leaves. It also helps to give AI tools a clean map of your site with [llms.txt](https://www.ectobuilder.com/blog/ghost-llms-txt/). That's phantom AI traffic: real people, sent by an AI assistant, to a page that doesn't exist. This guide covers how often it happens, how to see it on your own site, and how to turn the best of those URLs into posts that do exist. ## How often do AI assistants link to pages that don't exist? Not often, but more often than Google. Ahrefs looked at clicks from AI assistants to millions of URLs and checked how many landed on a 404 page. Across assistants, 0.43% of clicks hit a missing page, nearly three times Google Search's 0.15%. ChatGPT had the highest rate at 1.01%. ![Bar chart: share of clicks that land on a 404 page. ChatGPT 1.01%, Claude 0.58%, Copilot 0.34%, Perplexity 0.31%, Gemini 0.21%, all AI assistants 0.43%, Google Search 0.15%](https://www.ectobuilder.com/content/images/2026/10/ai-404-rates-chart.webp) Data: Ahrefs, 16 million URLs studied, September 2025. SE Ranking ran a separate test in December 2025 on 100,000 ChatGPT prompts and found that 1.22% of the URLs it cited returned a 404, about twice the rate of Google's AI Overviews. Some of those 404s are pages that existed once and were deleted or moved without a redirect. Others never existed at all: the assistant guessed a URL that fits how your site is built. Either way, the visitor is gone. ## Is it worth your time? Be realistic. Ahrefs estimates AI assistants send around 0.25% of a typical site's traffic, and only a fraction of that hits a missing page. For most sites this is a handful of visits a month, not a growth channel. But two things make those visits more interesting than the numbers suggest: - **They're high intent.** Someone asked a specific question and was told your site has the answer. That's a warmer visitor than most search clicks. - **They're free topic research.** When an assistant keeps inventing the same URL on your site, it's telling you what people expect you to have written. A phantom URL that gets ten visits a month is a post idea with demand already attached. ## How to see phantom AI traffic on your site You need two facts per visit: the page was missing, and the visitor came from an AI assistant. Most analytics tools record the second but not the first. ChatGPT helps a little by adding `utm_source=chatgpt.com` to the links it shows, and other assistants pass their own domain as the referrer. In Ectobuilder, **Log missing pages** records both. Your theme's 404 page reports every missing URL with its source, and the list in **Settings β†’ SEO** marks visits from ChatGPT, Claude, Perplexity, Gemini and Copilot so they stand out from old links and search traffic. ![Ectobuilder missing pages list: /blog/ghost-pricing-2026/ with visits from ChatGPT and Perplexity, /ghost-seo-checklist/ with visits from Claude and Gemini](https://www.ectobuilder.com/content/images/2026/10/missing-pages-panel.webp) AI sources are highlighted in the list. Example data. Switch it on, deploy your theme, and give it a few weeks. Phantom URLs come in slowly, and the useful ones repeat. ## What to do with each phantom URL Go through the list from the top. For every URL with AI visits, pick one of three answers. ### 1\. Write the page If the URL describes something you could genuinely write, and it keeps getting visits, write it. Use the exact slug the assistant invented, so the existing links start working on the day you publish. `/blog/ghost-pricing-2026/` getting a dozen visits a month from ChatGPT and Perplexity is a strong hint that a Ghost pricing post would find readers. Make it a real post that answers the question, not a thin page made to catch the click. A page with nothing on it is a worse experience than a 404, and it won't earn citations of its own. ### 2\. Redirect to the closest real page If you already cover the topic under a different URL, redirect. The assistant guessed `/ghost-seo-checklist/`; you have `/blog/ghost-seo/`. In Ectobuilder, type the target into **Redirect to…** next to the row (it suggests your real posts and pages), click **Redirect**, then download `redirects.yaml` and upload it in Ghost Admin under **Settings β†’ Labs β†’ Redirects**. ### 3\. Dismiss it One visit to a URL nobody will ever ask about again isn't worth a redirect. Dismiss it and move on. Don't redirect every miss to your homepage either: search engines treat that like a 404, and the visitor still doesn't find what they wanted.

Ahrefs suggests the same: - **A search box**, so the visitor can look for what the assistant promised. - **Your most popular posts**, as a short list of links. - **A newsletter signup.** These visitors were looking for your expertise; some will subscribe even without the page they wanted. In Ectobuilder the error page is a page like any other: open it in the editor and add a posts section, a signup form or a search link from the library. ## Help assistants get your URLs right You can't stop an assistant from guessing, but you can make the right answer easier to find: - **Keep URLs predictable.** Short, descriptive slugs that match the title make an assistant's guess more likely to be a real page. - **Never delete without a redirect.** Many "hallucinated" links are old pages that were removed. If you retire a post, redirect it. - **Keep your sitemap current.** Ghost generates `/sitemap.xml` for you; make sure nothing blocks it. - **Add structured data.** Breadcrumbs and FAQ markup give search engines and assistants a clearer map of your pages. Ectobuilder's SEO settings add both. ## The other source of 404s If you recently moved to Ghost, most of your missing pages will be old URLs from your previous platform, not AI guesses. The same list catches both. See [how to find every missing page after moving to Ghost](https://www.ectobuilder.com/blog/ghost-migration-redirects/) for the redirect patterns that cover WordPress, Substack, Squarespace and Wix. ## FAQ #### Why does ChatGPT link to pages that don't exist? Sometimes the page existed once and was removed. Other times the model builds a URL that fits your site's pattern and the topic, without checking that it's real. #### How do I know a visit came from ChatGPT? ChatGPT adds utm\_source=chatgpt.com to the links it shows, and most assistants send their domain as the referrer. Ectobuilder's missing pages list reads both. #### Should I create a page for every URL an AI invents? No. Only for URLs that keep getting visits and describe something you can write well. Redirect the rest to the closest real page, or dismiss them. #### Will a redirect fix the link inside ChatGPT? No, the assistant may keep giving the same URL. The redirect makes sure that whoever clicks it still lands on the right page. ## Sources - [Ahrefs: How Often Do AI Assistants Hallucinate Links?
