If you manage redirects for multiple domains, you have probably encountered this problem: each domain needs its own robots.txt, ads.txt, and the newer llm.txt. Setting these up on redirect domains is tricky — until now.

Why These Files Matter

robots.txt

Controls which search engine bots can crawl your site and which pages they should avoid. Without a proper robots.txt, bots may crawl and index your redirect pages instead of following them.

ads.txt

Authorized Digital Sellers — a text file that declares which ad networks are authorized to sell your inventory. Required by Google AdSense, Google Ad Manager, and most programmatic advertising platforms. Without it, you may lose ad revenue.

llm.txt

A newer standard that tells AI language models (ChatGPT, Claude, Perplexity) what content they are allowed to use. As AI-powered search grows, llm.txt is becoming increasingly important for content publishers.

The Problem with Redirect Domains

When a domain is set up purely for redirects, it typically does not have a web server serving files. Requests for /robots.txt either return a 404 or get caught by the redirect rule — sending bots to your target site's robots.txt, which is wrong.

LinkVice Solution

LinkVice handles these special files automatically. For each redirect, you can enable:

• Redirect robots.txt — Serves the target domain's robots.txt (or a custom URL)
• Redirect ads.txt — Serves the target domain's ads.txt (or a custom URL)
• Redirect llm.txt — Serves the target domain's llm.txt (or a custom URL)
• Redirect favicon — Serves the target domain's favicon.ico/favicon.png

All four are enabled by default for new redirects. You can also specify custom URLs if the files are hosted elsewhere (e.g., a CDN or a different path).

How It Works

When a request comes in for yourdomain.com/robots.txt, LinkVice:

1. Detects it is a special file request
2. Checks if the redirect has the corresponding option enabled
3. Redirects to the target domain's equivalent file (e.g., targetdomain.com/robots.txt)

This means your redirect domains automatically serve the correct robots.txt, ads.txt, and llm.txt from their target domains — with zero configuration.
