When it breaks
The AdSense ad serving limit
Your Policy center shows "Ad serving is currently limited," impressions fell off a cliff, and the account still logs in like nothing happened. This is limbo, and it runs on Google's clock, not yours. Here is what Google actually says about it, quoted from its own pages, plus what helps while you wait and what quietly makes it worse.
Not sure this is your failure? Impressions collapsing with a Policy center notice is a serving limit. Revenue falling while impressions held is a different problem. If you have not diagnosed it yet, start at the triage quiz.
What it is
A throttle, not a ban
Google says it "may sometimes place a limit on the number of ads your AdSense account can show." Your account stays fully accessible, your content keeps ranking, and the details of the enforcement sit in the Policy center inside your account. Nothing is closed. What has changed is that Google is filling far fewer of your ad requests while it assesses your traffic.
That distinction matters, because the two failure modes get conflated in every forum thread. A serving limit is Google slowing down while it decides whether your traffic is clean. An account closure is Google deciding it was not. They have different mechanics, different timelines, and only one of them has an appeal. If your notice says the account is closed or disabled, you want the disabled-account page instead.
The two kinds
What Google names, in Google's words
1. Account being assessed
Google's description: "Ad serving on your account is being temporarily limited while we assess your traffic quality." Its help page frames this kind as "a temporary ad serving limit while we get to know you and evaluate your traffic quality," which is why it shows up so often on new accounts and after sharp changes in where traffic comes from. On duration, the same section is blunt: "We'll automatically review and update this limit as we continue to monitor your traffic. Unfortunately, we can't say how long this will take."
2. Invalid traffic concerns
The second kind is heavier: "Ad serving on your account is currently being limited due to invalid traffic concerns." Same automatic review, same open-ended clock, but the cause is named: something in your clicks and impressions looks, to Google's systems, like it is not coming from genuine reader interest. Google's resources for this state point at the usual suspects: purchased traffic, your own clicks, and traffic sources you do not actually understand.
Which kind you have is not a guess. Open the Policy center in your AdSense account; the enforcement notice names it.

Duration
How long it lasts: the honest answer
Google publishes exactly one sentence on this, and it is a hedge: "While this ad serving limit typically impacts publishers for less than 30 days, it may take longer in some cases." That is the whole commitment. There is no fixed end date, no progress bar, and, in Google's own words, no answer to "how long": the review is automatic and continuous as it monitors your traffic.
Google's Guide for Ad Serving Limits adds the detail most posts leave out: "If we detect any issues after lifting a limit or no longer have sufficient information to evaluate, we may need to reinstate the limit while we evaluate further." A lifted limit can come back. So when serving resumes, do not restart whatever traffic source you paused; that is the most common way to end up in limbo twice.
One more thing worth saying plainly: Google's pages offer no appeal form and no expedite path for a serving limit. Anyone selling you a "limit removal service" is selling you the calendar.
While it runs
What to actually do
- 1. Keep publishing. Google's own advice for the assessment state: "Continue to build your content and audience while we assess your site traffic." The limit throttles ads, not rankings. The site you have when it lifts is the site that earns.
- 2. Read the Policy center notice. It tells you which of the two kinds you have and holds the details of the enforcement. Everything else you will read about your situation is inference; this is the one primary source you have.
- 3. Audit where your traffic comes from. Google's resources for the invalid-traffic state are about knowing your own acquisition. Open your analytics and look for what changed before the limit: unfamiliar referrers, a geography spike out of pattern, a traffic vendor, a social blast, an exchange or widget sending "visitors." If you cannot explain a source, that is the finding.
- 4. Stop anything that buys visitors. Google's serving-limits page points publishers with invalid traffic concerns at its purchased-traffic guidance, and its closure FAQ asks appellants directly whether purchased traffic caused the surge. "Real human visitors" packages are not an exception; they are the category.
- 5. Never touch your own ads. Clicking your own ads, even to "check they work," is the first item on Google's list of common causes. Screenshots exist.
Anti-patterns
What usually does not help
| The tempting move | Why it does not work |
|---|---|
| Open a second account | AdSense terms allow one account per publisher, and Google says it may close accounts it determines are related to a closed one. This converts a temporary limit into a permanent problem. |
| Shuffle ad units and layouts | Both kinds of limit are traffic assessments. Nothing in Google's description of either is about placement, so placement changes cannot address the thing being assessed. |
| Buy traffic to make up the revenue | Google's escalation note is explicit: "your account may be subject to further enforcement actions or may be permanently closed" if invalid activity is detected. Buying traffic during an invalid-traffic review feeds the review. |
| File tickets and forum posts asking for a lift | The review is automatic. Google publishes no human queue, no appeal form, and no expedite path for serving limits. The community threads are full of people waiting; none of them waited faster. |

Use the quiet weeks
Google publishes no statistics on how limits resolve; serving returns when the assessment ends, and a lifted limit can be reinstated. While the clock runs on Google's side, the layout is the one thing fully on yours: the free scan reads your live setup with no ad revenue required, and the AdSense playbook is the ranked list of what to fix before the impressions come back. If it ends badly instead, the closure process and its one-shot appeal are covered on the disabled-account page. The rest of the failure modes live at When it breaks.
