How Meta's Ad Review Actually Works
According to Meta's official Business Help Center, every ad goes through a review process before it can start running. This review typically takes up to 24 hours and examines several components:
- Ad creative — images, videos, and text for policy compliance
- Targeting — audience settings and potential discrimination
- Landing page — whether the destination URL is functional and matches the ad content
Meta uses a combination of automated systems and human reviewers to check these elements. If a landing page returns a 404 error at the time of review, the ad will be rejected. According to digital advertising resource Adamigo.ai, Meta's landing page requirements include: pages must be functional, load quickly, work across devices, and align with the ad's content.
The Critical Gap: No Ongoing Monitoring
Here's the key issue that many advertisers don't realize: Meta's review is a one-time check at submission time. Once your ad passes review and starts running, Meta does not continuously monitor whether your landing page remains functional.
This means that if your landing page goes down — due to a server outage, a CMS update, an expired SSL certificate, or any other reason — your ad will continue to run and you will continue to be charged for clicks, even though every single click leads to a dead page.
A Timeline of How Things Go Wrong
Day 1: You submit your ad. Meta reviews it, checks the landing page (it works), and approves the ad.
Day 1–14: Your ad runs normally. Users click, land on your page, and some convert. Everything is fine.
Day 15: Your IT team updates the CMS. A URL structure changes. Your landing page now returns a 404 error.
Day 15–20: Your ad is still running. Meta keeps charging you. Every click goes to a 404 page. 0% conversion rate. You don't notice because the ad metrics in Ads Manager show "clicks" — not "successful page visits."
Day 20: Someone (a customer? a colleague?) finally tells you the page is broken. You've wasted 5 days of ad budget.
Why Doesn't Meta Monitor Landing Pages Continuously?
There are several likely reasons why Meta doesn't offer ongoing landing page monitoring:
- Scale — Meta serves millions of active advertisers running millions of ads simultaneously. Continuously monitoring every landing page URL would require enormous infrastructure.
- Meta's business model — Meta charges per impression or per click. From a revenue perspective, there is no financial incentive for Meta to stop delivering (and charging for) ads whose landing pages have broken. This isn't necessarily malicious — it's simply not part of their platform design.
- Advertiser responsibility — Meta's Advertising Standards place the responsibility for maintaining a functional landing page on the advertiser, not on the platform. This is consistent with how most ad platforms operate.
- Technical complexity — Some landing pages use dynamic content, personalization, or geo-targeting. A page might work from one location but not another, or work for some users but not others. This makes automated monitoring at Meta's scale extremely complex.
How Other Ad Platforms Handle This
For context, Google Ads has a similar approach. According to Google's support documentation, ads are reviewed at submission for policy compliance, including landing page quality. However, Google Ads also checks periodically and may disapprove ads if the landing page becomes non-functional — this happens through their "landing page experience" quality score component, but it's not designed as a real-time alert system for advertisers.
Neither Meta nor Google Ads provides real-time notifications when a landing page goes down. Both platforms will continue to deliver ads and charge for clicks regardless of the landing page status.
The Metrics That Warn You (If You Look)
While Meta doesn't actively alert you, there are signals in your Ads Manager data that something might be wrong:
- Link Clicks vs. Landing Page Views — A large gap between these two metrics can indicate that users are clicking but not reaching your page. As noted by Meta's metrics documentation, "Landing Page Views" counts only when a user successfully loads the destination page.
- Sudden conversion drop — If your conversion rate drops to zero overnight with no change in ad settings, a broken landing page is a likely culprit.
- High bounce rate in Google Analytics — If your analytics shows visitors arriving and immediately leaving (100% bounce rate from Facebook traffic), your page might be returning an error.
However, monitoring these metrics manually requires checking your dashboards frequently — and by the time you notice the anomaly, you've likely already lost significant budget.
Bridging the Gap with Automated Monitoring
The gap between Meta's one-time review and the reality of ongoing landing page health is exactly why dedicated monitoring tools exist. 404Watcher was built specifically to fill this gap:
- It connects to your Meta Ads accounts via the official Meta Graph API with read-only permissions
- It automatically checks every URL in your active ads every 24 hours
- When a broken link is detected, you receive an instant email alert with the ad name, campaign, and affected URL
- You can then pause or fix the ad immediately — before losing significant budget
Key Takeaways
- Meta reviews landing pages only once — at ad submission time
- After approval, Meta does not monitor whether your landing page remains functional
- Ads will continue running (and you will continue paying) even if your page returns a 404 error
- Neither Meta nor Google Ads will send you real-time alerts about broken landing pages
- Automated daily monitoring is the only reliable way to catch broken links before they drain your budget
