A better ending for zero results
Let your visitors keep searching with SAGE.
Add one small, privacy-forward button to a genuine zero-result page. Nothing is sent to SAGE until the shopper chooses Let SAGE find it. SAGE then checks independent-shop inventory and can keep a private watch running.

<script src="https://indieco.shop/sage-infinite-search-embed.js" data-target="#keep-looking" data-query="YOUR ZERO-RESULT QUERY" data-source="YOUR-SITE-zero-results"></script>Use this only after your own search returns no useful result. Set data-query from the visitor's visible search and give data-source a short name for your site. The script is read-only and does not reserve, buy, message, or track a visitor before they choose to continue.
