"Limited by budget" means the campaign is active and showing ads, just not as often as it could, because the average daily budget runs out before the day's searches do. It is not an error, and it is often fine. The mistake is treating every status label as a reason to spend more. Learning, Eligible (limited), Not eligible and Under review each ask for something different, and the budget simulator and the Ad preview and diagnosis tool tell you which one you actually have.
The status labels, with Google's own definitions
The Status column mixes campaign statuses, bid strategy statuses and ad statuses, and they are documented on different pages. The table puts the labels a business owner meets side by side, each with the page where Google defines it.
| Status label | Google's definition | What it means for you | Official source |
|---|---|---|---|
| Eligible | "The campaign is active and can show ads." | Nothing to fix at campaign level. If there are no impressions, look at the ads and keywords. | Campaign status definition |
| Limited by budget | "The campaign is active and can show ads, but not as often as it could due to budget constraints." | Normal for a tight budget. Decide whether more clicks at this cost per lead are worth buying. | Campaign status definition |
| Eligible (limited) | "The campaign is active, but showing ads only occasionally due to budget constraints." | The milder cousin. Same decision as above. | Campaign status definition |
| Limited by budget soon | A forecast status based on seasonal events that can raise traffic temporarily. Shown when the simulation predicts a 5% or more drop in weekly traffic at the current budget. | Open the budget simulator and decide before the season, not during it. | Troubleshoot Limited by budget soon |
| Learning | A bid strategy status shown after a new strategy, a composition change or a goal change. "It never lasts more than 7 days." | Do not judge results or change settings during it. Changing budget does not trigger it, but changing the bid strategy does. | About bid strategy statuses |
| Limited (bid strategy) | "Your bid strategy is limited by one of the following 4 factors", namely inventory, bid limits, budget constrained, or the bidding strategy itself. | Hover the status. Only one of the four is solved by budget. | About bid strategy statuses |
| Misconfigured | A conversion based strategy with no usable conversion action, or a Maximize strategy sharing a budget with campaigns on other strategies. | Fix conversion tracking or the shared budget. Money does not help here. | About bid strategy statuses |
| Eligible (Misconfigured) | "Your website is missing a Google tag", usually meaning no biddable conversions were recorded in the last 28 days. | Install or repair the tag before touching bids. | About campaign status |
| Not eligible | "Campaign is inactive because there are no ad groups, all ad groups are paused or deleted", or all ads or keywords are paused or deleted. | Something inside the campaign is switched off. Open it and look. | Campaign status definition |
| Pending | "The campaign has a start date in the future, so its ads have not started running yet." | Check the start date. Nothing else is wrong. | Campaign status definition |
| Paused, Ended, Removed | "The campaign and its ads aren't running because you have paused it", passed its end date, or was permanently deleted. | Paused and Ended can be resumed. Removed cannot. | Campaign status definition |
| Under review (ad) | "The ad is still being reviewed and will be eligible to serve if we determine that it complies with our policies." | Most reviews finish within one business day. Do not edit the ad, since edits restart the review. | Find your ad status |
| Campaign paused / Ad group paused (ad) | The ad is fine. Its parent campaign or ad group is paused. | This is the "Paused by" case most people search for. Resume the parent. | Find your ad status |
| Low search volume (keyword) | The keyword rarely qualifies to show ads because it gets very little search traffic. | No budget fixes this. Broaden the term or the match type. | About keyword status |
What each one means for a business owner
Three questions sort the whole table. Is the campaign switched on? Is it allowed to show? Is it being outbid or starved? Not eligible, Pending, Paused, Ended and the "Campaign paused" family answer the first question. Under review, Disapproved and the verification holds answer the second. Limited by budget, Eligible (limited), Learning and the Limited bid strategy family answer the third, and only the third involves money.
The two expensive confusions are between Learning and Limited by budget, and between Limited by budget and Not eligible. Learning is time. Google says the status never lasts more than 7 days and that budget changes do not trigger it, on the bid strategy statuses page. Raising the budget while a strategy is learning adds a variable to a system that is already recalibrating. Not eligible is structure. A paused ad group or a disapproved ad is not fixed by a bigger budget, it is fixed by turning something back on.
When "limited by budget" is actually fine
The label appears whenever Google believes it could spend more on your targeting than you allow. Its own page says the status is applied in two cases, when "Your campaign is underperforming due to a limited budget" and when "You're using Maximize Clicks bidding and could increase traffic by adjusting your budget", and that no recommended budget is shown if you rarely meet the average daily budget or the campaign has limited data, per the page on fixing the status.
Neither case says the campaign is broken. A plumbing company with a fixed number of trucks, a clinic with a full calendar, or a business whose cost per lead is already at the ceiling is correctly limited by budget. The question is not whether Google could spend more. It is whether the next lead at this price is worth having, which is the arithmetic in whether ten dollars a day is enough and in what a good cost per click looks like in your industry.
Two mechanics matter before you react to the label. Google may spend up to twice your average daily budget on a given day, and over a month no more than 30.4 times that daily figure, according to the page on average daily budgets. So a limited campaign still has busy days, and the monthly cap is what you actually control. If you work from a monthly number, divide it by 30.4 to get the daily budget, as the budget basics page recommends.
The trap of raising budget to fix a bidding problem
Here is the pattern I see most in audits. A campaign shows Limited by budget, the owner raises the budget, spend goes up, leads do not. The label was true, but the cause was the bid strategy. Google's own troubleshooting page separates the two. It says a Limited by budget status may call for an increase of about 20%, and in the same list it says low bid targets win fewer auctions and suggests raising a Target CPA by 10 to 20% or lowering a Target ROAS, per the page on campaigns not running or with low traffic.
The tell is in the bid strategy status. When it reads Limited and the hover says "Bid limits" or "Bidding strategy", the constraint is the bid, not the budget. When it says "Budget constrained", it is the budget. And when it says "Inventory", there are simply not enough searches, and neither lever helps, per the bid strategy statuses page. The same troubleshooting page gives the sizing rule that stops most of this. A budget of at least 10 times the expected cost per click, or 2 to 3 times the Target CPA, and 30 or more conversions in 30 days before leaning on a conversion based strategy, according to the same page.
There is a quieter version of the trap. Conversion tracking counts a page view or a form that nobody qualifies, the strategy optimizes toward it, the campaign spends its budget efficiently on the wrong thing, and the label says Limited by budget. More budget buys more of the wrong thing. That diagnosis is in the guide to Google Ads that is not converting.
How to see whether the ad is really not showing
Searching for your own ad is the wrong test, and Google says so. The Ad preview and diagnosis tool "helps you understand why your ad or ad asset might not be appearing" and shows a preview of the results page for a term, and using it "avoids accumulating ad impressions and impacting your performance statistics", per the tool's help page. Every time you search and do not click, you add an impression with no click to your own ad, and the ad's expected click rate pays for your curiosity. The tool sits under Tools, in the Troubleshooting section.
The tool has limits that are worth knowing. It simulates one auction. It does not reflect your search history, location, device or the live competition, and an ad that does not appear in the tool is not necessarily failing to appear at all, according to the page on why you may not see your ad. The same page lists what to check instead. Paused or Removed statuses, a campaign limited by budget, a bid strategy that reads Inactive, Limited or Misconfigured, keywords with Low search volume, Ad Rank, and whether the account has valid billing information, since ads do not run until it does.
The timing rule from Google is useful for owners who panic on day one. New or edited ads go through a one to 2 day policy review, and ads with no impressions after 3 business days should be checked against the common causes, per the troubleshooting page. Most reviews finish within one business day, and an ad still under review after more than a week is a reason to contact support, per the ad review process page.
What to do today
- Read the whole Status column, not just the campaign row. Open the campaign and check that the ad groups, ads and keywords are enabled and that none says Disapproved or Under review.
- Hover the bid strategy status. Write down which of the four Limited factors it names.
- Open the budget simulator from the chart icon next to the campaign. It shows the clicks you would get at other budgets, which is the only honest way to see what more money buys, as described on the page on the status.
- Check the conversion action the strategy is using. If it is not a lead you would pay for, fix that before any budget change.
- Run the Ad preview and diagnosis tool for your three most important terms and your main location.
- If, and only if, the bid strategy says Budget constrained and the cost per lead is one you want more of, raise the budget. Then leave it alone for a week.
While the campaign settles
After a budget or bidding change, Google asks for one to 2 conversion cycles before judging performance, on the troubleshooting page, and the Learning status can take up to 7 days. During that time, resist the second change. Each one restarts the clock. Use the week to tighten what does not disturb the strategy. Add negative keywords from the search terms report, following a negative keyword framework, so the limited budget stops buying searches you would never want.
On the money side, treat the monthly cap as the real budget. The daily figure times 30.4 is what Google can charge, and a campaign that spends twice its daily budget on a Tuesday is behaving as documented on the average daily budget page, not misbehaving. If that monthly number is too high for the business, the fix is a lower daily budget, not a complaint to support.
How to avoid the confusion next time
- Set the daily budget from the monthly number divided by 30.4, the figure Google gives on its budget basics page, and write the monthly number where you will see it.
- Size the budget to the cost per click before launch, using the published ranges in how much Google Ads costs.
- Put a real lead, not a page view, behind the conversion action before any automated strategy goes live.
- Hover statuses before acting on them. The hover text names the factor.
- Use the Ad preview and diagnosis tool, never a Google search, to look for your own ad.
- Change one thing at a time, and wait a week between changes.
If the account has had three budget increases this year and the lead count has not moved, the problem is upstream of the label. An independent PPC audit reads the statuses, the bid strategies and the conversion setup together and tells you which lever is actually stuck.
