Google Adds Examples to Destination Not Working Policy

Google added new examples to its Destination Not Working ad policy on September 30, and one 403 error served to its AdsBot crawler can keep ads disapproved.

Google says the update clarifies the policy and does not change enforcement, according to its Ads Policy Help Center announcement. For an ecommerce owner it still matters. The new examples read like a punch list of the exact ways high-ticket stores break their own ads: bot filters that lock Google out, geo-redirect apps that loop, pricing pages hidden behind a login, and hosting that times out. Readers of Ecommerce Paradise who sell $2,000-plus products on Shopping, Performance Max or Search lose real money every day a final URL fails.

Google’s Destination Not Working Policy: Nine Failures It Names

Search Engine Land reported on October 1 that Google expanded the guidance on its “Destination not working” policy, per author Anu Adegbola’s write-up. Google’s own notice, dated September 30, says it “has updated the Destination not working article to provide additional examples for destination issues for advertisers” and that this “does not change enforcement of the policy.”

The policy page itself now carries a table of causes. It names nine: HTTP 4xx and 5xx errors, DNS errors where the hostname cannot resolve, redirect URLs that run too long, empty or bad redirects, private IP addresses where a site sits behind a firewall, malformed HTTP responses, timeouts, redirect loops, and pages that require authentication. Visible failure pages count too. Google cites “You’ve reached this page in error,” “Whoops! Nothing to see here!” and “Site Under Construction.”

The sharpest line concerns the crawler. Per Google’s policy text, HTTP 403 Forbidden, 404 Not Found and 500 Internal Server Error responses returned to Google AdsBot are violations. Search Engine Land adds that ads may stay disapproved while a landing page returns one of those codes to AdsBot, which blocks the campaign from running.

Google also flagged a setup trap. Per Search Engine Land, a missing asset group configuration can trigger an “invalid final URL” error during campaign setup even when the destination URL itself works. That one hits Performance Max builds, where each asset group needs its own final URL.

On enforcement timing, Google’s policy page states that “a warning will be issued at least 7 days prior to any suspension” of an account. The fix path it lays out: check landing page and tracking parameter URLs for typos, test globally on common browsers, override the user agent in Chrome DevTools to simulate AdsBot, then edit the ad to point at a compliant page or file an appeal once the issue is fixed. Google tells advertisers the policy applies to “common browsers and devices globally,” so a page that loads in your office but fails from another region still counts.

AdsBot Skips Robots.txt Wildcards and Trips Over Bot Filters

The policy is not new. What is new is how specific Google got about the failure modes, and that specificity lines up with a failure one practitioner documented in a September post.

AdsBot is not Googlebot. Google’s special-case crawler documentation says AdsBot-Google ignores the global wildcard (*) user agent in robots.txt, so you control it only by naming the specific token, AdsBot-Google, or AdsBot-Google-Mobile for the mobile version. Google verifies its crawlers through reverse DNS and published IP ranges, and warns that anyone can spoof the user agent string. That last point matters: a firewall that checks IP ranges will treat a fake AdsBot differently from the real one.

Bot filters are the clearest example I found. Jonathan Bird, in a post published September 2 and updated September 16, described an August 2026 incident with about two weeks of downtime in which a Cloudflare bot setting blocked organic search, Google Ads and Merchant Center at once while the site loaded normally for regular visitors. He names three culprits: custom firewall rules that block overseas or automated traffic, Bot Fight Mode, and Super Bot Fight Mode or managed rules. Per his steps, you find the damage in Cloudflare’s Security Analytics, filtering events for the AdsBot-Google user agent and looking for “Block” or “Managed Challenge” actions.

Cloudflare’s own Bot Fight Mode documentation confirms the constraint Bird describes. It states that “you cannot bypass or skip Bot Fight Mode using WAF custom rules or Page Rules,” and it describes the feature as a simple, free product. Bird says Super Bot Fight Mode, by contrast, supports skip options.

Here is the counterpoint. Google says enforcement is unchanged, so nothing about the September 30 update puts a store in new jeopardy by itself. Bird’s account is one reported case, not a count, and I found no Google statement on how often bot filters cause these disapprovals. Google’s policy page covers Ads. The Merchant Center spillover in Bird’s story is his report, not something Google confirmed in the pages I reviewed, although Google’s Merchant Center rules do list sites that are “just not working” as violations. Treat the Cloudflare angle as a well-documented risk, not a Google-confirmed epidemic.

For context on how fast Google’s shopping surfaces are shifting, I covered the sponsored grid test that mimics free listings on September 30. Paid visibility keeps getting more valuable, which makes any silent block more expensive.

What a Blocked Crawler Costs a High-Ticket Shopping Campaign

My read: the policy text matters less than the failure pattern. This problem is silent. Your customers load the site fine, your team sees nothing wrong, and the only symptom is disapproved ads in a Google Ads dashboard that someone may not open for days. A store that gets most of its leads from paid Shopping traffic can lose its main channel without a single error alert going off. I laid out why high-ticket ad spend needs a full system around it in my piece on complete conversion systems, and a crawler lockout is the cheapest way to break that system.

Here is hypothetical math, not a reported figure. Say your store spends $200 a day on Shopping and Performance Max at a 4x return, so $800 a day in attributed revenue. With a $1,800 average order, that is roughly one order every two days. A bot filter that gets final URLs disapproved for 10 days costs about $8,000 in attributed revenue, or four to five orders. If the block runs two weeks, as in the incident Bird described, the same store books around $11,200 less. I would also expect the campaigns to need time to recover their bidding data afterward, though I have not seen Google quantify that.

Scenarios, with thresholds:

If a handful of ads show “Destination not working” and the rest run, you have a page-level bug. Fix the URL, retest, and appeal the same day. If disapprovals spread across many final URLs at once, treat it as a sitewide outage and look at the firewall before touching a single ad. If Google Ads shows an account-level warning, Google’s own policy gives you at least 7 days, but I would not spend a single one of them waiting.

Four kinds of high-ticket stores are most exposed. The first runs Cloudflare with Bot Fight Mode switched on, which cannot be skipped per the docs above. The second runs a geo-redirect or currency app that can loop or misroute a crawler. The third gates dealer pricing or “request a quote” pages behind a login, which Google lists as a failure under its authentication cause. My comparison of geo-redirect tools for Shopify covers the loop risks in that second group. The fourth redesigned its theme recently, and the new Shopify Canvas feature that lets Sidekick redesign your whole store makes a mass URL change easier than ever, so every redesigned collection and product page deserves a status check.

Timing makes this worse. Holiday spend ramps in the next few weeks, and I wrote about Prime Big Deal Days starting October 6 for exactly that reason. A week of lost impressions in October is a bad week to lose.

Infrastructure is the other half. A timeout is a destination failure, and so is a DNS error. If your host is slow, moving to managed hosting like Cloudways is a real fix for WooCommerce builds. SiteGround is the other host I would price out before deciding.

If your domain registrar is the weak link, Namecheap gives you DNS control you can monitor. On Shopify, the platform runs hosting and DNS for you, which is one reason I keep pointing new high-ticket owners there. You still own the apps, redirects and any CDN in front of the store.

Disruptions like this belong in your continuity plan too. I covered the basics in building an e-commerce business continuity plan. The same logic applies to payments, and I wrote about it in why your processor is a single point of failure.

Audit Your Final URLs for AdsBot This Week: 6 Steps

Run these in order. Each one takes under an hour for a normal-sized catalog.

Export every final URL in your account, including Performance Max asset groups, sitelinks, and any tracking template or final URL suffix, then crawl them for status codes and redirect chains. A site crawler such as Semrush will flag anything that is not a clean 200. Confirm every asset group has a final URL, since Google says a missing configuration can throw an “invalid final URL” error on its own.
Override your browser’s user agent in Chrome DevTools to the AdsBot-Google string and load your top 20 landing pages. Google recommends this test. Remember that your browser is not Google’s IP range, so a pass here does not clear you if a firewall checks by IP.
Read your firewall and CDN logs for AdsBot-Google hits. In Cloudflare, per Bird’s steps, use Security Analytics, filter the user agent for AdsBot-Google, and look for blocks or challenges. If Bot Fight Mode is on, turn it off or move to a tier that supports skip rules, because the docs say it cannot be bypassed.
Open your robots.txt and look for any rule that names AdsBot-Google or AdsBot-Google-Mobile. A disallow under the wildcard does not affect AdsBot, but a named rule does.
Test redirects from outside your country, since Google says the policy applies globally. A VPN such as Surfshark lets you load pages from other regions and catch geo-app loops, www and non-www conflicts, and http to https chains. Fix any chain longer than a single hop.
Put the check on a schedule. Assign a weekly sweep of Policy Manager and a status check on your 20 best landing pages to a VA, and an OnlineJobs.ph hire is the cheapest way I know to cover it. If you want a second set of eyes on your whole setup, book a call at my discovery page.

Keep tracking tags in mind while you audit. Google is also changing how tags work, which I covered in Google turning every Google Tag into a GTM container, and a bad tracking template is one of the typo sources Google tells you to check.

Frequently Asked Questions

Did Google change how it enforces Destination Not Working?
No. Google’s notice says the update adds examples and “does not change enforcement of the policy.” What changed is how clearly it names the failure causes, including 403, 404 and 500 responses to AdsBot.

How do I test my store the way AdsBot sees it?
Google’s fix steps say to override the user agent in Chrome DevTools to simulate AdsBot. That checks your site’s response to the user agent only. For a firewall that verifies Google by IP range, read your server or CDN logs for real AdsBot requests, as covered in the Google crawler documentation.

Does a robots.txt rule that blocks all bots stop AdsBot?
Not through the wildcard. Per Google, AdsBot ignores the global user agent entry, so only a rule naming AdsBot-Google or AdsBot-Google-Mobile controls it. Make sure you never added one by accident.

Will Google suspend my account over this?
Google’s policy says a warning arrives at least 7 days before any suspension. I would expect disapproved ads, not a suspension, from a single blocked crawler. Fix the cause, retest, and file the appeal from Policy Manager once the page returns a 200.

Does this affect my free Merchant Center listings?
Google’s Destination Not Working page is about ads. Google’s Merchant Center rules separately list sites that are “just not working” as violations, and Bird reported that his August Cloudflare block hit organic search, Ads and Merchant Center together. Fix the access problem and you cover both. My guide on turning Google Shopping clicks into sales covers what to do after the traffic arrives.

Can I keep dealer pricing behind a login and still run ads to it?
Google lists pages that require authentication as a cause of this error, so send ads to a public page and keep the gated area behind it. A public quote form is the safer destination, and it pairs well with the phone number you should already show on every page.
