What this means for your shop
Only 47% of audited sites publish an llms.txt file, so adding one is a step many of your competitors have not taken.
None of the audited sites block AI crawlers (0%), so check that your own settings do not shut them out.
LocalBusiness schema appears on 87% of audited sites and analytics on 80%, so lacking either leaves you behind most of your peers.
