# Usage: bash ping.sh   (edit HOST, KEY and URLS first)
# Purpose: tell IndexNow participants (Bing and others, NOT Google) that URLs changed. Ping only recently changed URLs.
# Checked against the IndexNow docs and FAQ: global endpoint api.indexnow.org, up to 10,000 URLs per POST, submissions are shared with participating engines.
# It proves the request was accepted, not that anything was indexed. Replace every placeholder (example.com and the key).
