I’m trying to set up a Google Ads campaign, of the “Performance Max” type (so including tpc.googlesyndication.com bot requests), and I keep getting a “Destination Unreachable” policy violation which limits the ads. Before you ask, YES! I’ve allowed the Google ASN 15169, and known Google User Agents, and any source URL’s I can find like googlesyndication.com - these are done with a Skip rule in WAF. I also allow Known Bots in a second Skip rule, before a Country blocking rule.
What needs to be added to WAF, or done otherwise, to allow the ads to work unhindered? To be clear, these are not ads ON my site, rather ads which POINT TO my site via Cloudflare.
This actually seems more like a Cloudflare problem in not allowing Google Syndication bots as a Rule option or inclusion in Known Bots, as opposed to a Google problem in not playing nice with Cloudflare.
