Automatic llms.txt via Cron Job
Set it up once – runs automatically forever. The cron job regenerates your llms.txt weekly on the server, without a browser, without manual uploads. Exclusive to the Pro plan.
How the Cron Job Works in Detail
The cron job script update-llmstxt.php automatically loads all relevant sitemaps from your shop after setting up your config.json. It refreshes only the URL selection you made in the generator and locked in the package (selection.json) – titles, prices, availability –, orders categories, products and brands by your priority, and writes the finished llms.txt and llms-full.txt files directly to your webroot directory.
Each run logs success, the number of processed URLs and any errors to a local log file – giving you full visibility without manual intervention. If the licence key is invalid, the script aborts safely and existing files remain unchanged.
The recommended cron expression 0 3 * * 0 runs the update on Sundays at 3:00 am – outside peak traffic hours. For shops with frequent product changes, a daily run is also possible. The licence allows unlimited runs and unlimited domains.
Requirements: PHP 7.4 or newer, the cURL extension, and write permissions in the target directory. A complete setup guide and the config.example.json are available in the generator after upgrading to Pro.
