What Limited by Budget and Eligible Limited Mean in Google Ads

A Google Ads campaign marked Limited by budget is still running, but Google is holding its ads back because the daily budget cannot cover all the traffic the campaign could win. Eligible (Limited) looks similar in the Status column but can mean something quite different, from a policy restriction on an ad to a bid strategy that is still learning. Reading each status correctly decides whether the answer is more budget, different bids or no change at all, which is why status checks belong in any routine of Google Ads management for growing businesses.

The sections below set out Google’s own definitions for each status, the causes behind them and how impression share lost to budget and rank shows which problem a campaign has. They finish with the changes that fix each cause and the cases where a limited status is safe to leave alone.

What Limited by Budget Means in Google Ads

Limited by budget means the campaign’s average daily budget is lower than the amount Google recommends to capture all the impressions and clicks available for its current settings. Google’s help page on the Limited by budget status explains that Google Ads reduces how often the ads appear so the budget does not run out too quickly. The campaign keeps running but misses some of the auctions it could have entered.

The status appears in the Status column of the campaigns table. Google’s glossary entry for campaign status adds that placing the mouse over the bubble next to the status shows the recommended budget for that campaign.

Google names three common causes for the status. Bid adjustments for locations, devices or audiences can make ads eligible for more auctions without a matching rise in budget. Target CPA and Target ROAS strategies can aim for outcomes that need higher bids than the budget supports. A daily budget can also be set too low for the targeting and the competition around the chosen keywords.

Google changed how its bidding systems treat these campaigns from 17 August 2026. Its notice on changes to bid strategies that use targets explains that campaigns limited by budget and using Target CPA or Target ROAS now deliver more closely to the target that has been set. A campaign that was beating its target may see results drift towards it. Google will not adjust budgets or targets automatically, so any campaign with a target well away from its recent results needs a manual review.

What Eligible (Limited) Means for Campaigns and Ads

Eligible (Limited) means the campaign or ad can run but is held back in some way. The reason depends on whether the label sits on a campaign or on an ad, because Google uses the same words for two different problems.

At campaign level, Google’s page about campaign statuses describes Eligible (Limited) as a campaign that is active but showing ads only occasionally because of budget constraints or a limited bid strategy. The same page lists Limited, Misconfigured and Learning as bid strategy statuses that surface in the campaign Status column.

At ad level, Google’s Eligible (Limited) definition covers ads that comply with its policies but are restricted in where and when they can show. Google’s guide to finding your ad status adds a separate status, Eligible (limited all locations), for ads that cannot run in the targeted locations because of policy restrictions and targeting settings.

A campaign can carry more than one of these at once, such as a budget limit on top of a bid strategy that is still learning. Working through them in the order of the table separates a spending problem from a policy or data problem before anything is changed.

Policy Limits Behind an Eligible (Limited) Ad

An ad marked Eligible (Limited) is usually held back by an advertising policy rather than by its budget. Google’s definition names policies such as Alcohol, Gambling, Healthcare and Trademarks, which stop certain ads showing in some locations, to some age groups or on some devices.

The restriction can also come from the website rather than the ad. Google notes that an ad can be limited when the website contains terms linked to regulated industries, even when the products or services being advertised are compliant. Healthcare is one of the policies Google names, so healthcare PPC campaigns need landing page copy checked as carefully as the ad text.

The reason for the limit shows in the Policy details column. Google’s ad status guide explains that this column, added from the Attributes section when modifying the columns on the Ads page, shows why an Eligible (Limited) ad is limited to a certain audience.

If the label looks wrong, Google allows an appeal. Its definition page points to the process for fixing a disapproved ad, which is also the route for challenging a policy restriction that has been applied in error.

Bid Strategy Learning and Limited Bid Strategies

A campaign can also show Eligible (Limited) while its bid strategy is learning or limited, which has nothing to do with policy. Google’s page on bid strategy statuses says a Learning status appears after a new strategy, a setting change or a change to the campaigns, ad groups or keywords the strategy covers.

Google’s guide to the duration of the learning period says it can take up to around 50 conversion events or three conversion cycles for a strategy to calibrate. The length depends on conversion volume, the time a click takes to become a conversion and the bid strategy itself. Google’s troubleshooting advice for a campaign showing Eligible (Limited) after a budget increase or bid strategy change is to allow 7 to 10 days for the system to adjust.

A Limited bid strategy is different, because a setting or a shortage of searches is stopping it from bidding as it would like. Google names four factors that cause it. Hovering over the status in the Status column shows which one applies.

• Inventory, where ads are eligible for only a small number of searches and the fix is broader targeting or more relevant keywords
• Bid limits, where maximum or minimum bid limits stop the strategy setting the bids it wants
• Budget constrained, where many keywords using the strategy are limited by budget so bids cannot rise enough to meet the goal
• Bidding strategy, where Google recommends moving the campaign to a fully automated strategy

Bid limits and targets are the two settings Google points to for a strategy that is limited by bid strategy. Its troubleshooting page describes a maximum CPC that is too low, a Target CPA set too low or a Target ROAS set too high, so those settings deserve a review against recent results before the budget is raised.

Our guide to Google Ads bidding strategies covers how each automated option chooses its bids. The choice matters here because the learning period runs longer when a strategy has few conversions to learn from.

Low Search Volume and Narrow Targeting

Low search volume limits a campaign when its keywords or targeting leave too few searches to bid on. Google’s definition of Low search volume describes a keyword status for terms with very little search history on Google. Those keywords stay inactive until search traffic for them rises.

Google checks the status regularly and reactivates a keyword once searches pick up. Its suggested fixes are to wait, to remove the keyword and find new ideas in Keyword Planner, to broaden the match type or to make the keyword less specific.

The status is unrelated to Quality Score, bids or ad text, so editing those will not change it. Broadening the match type is one of the routes Google suggests. Our guide to Google Ads keyword match types explains how phrase match and broad match widen the searches a keyword can reach.

Narrow targeting causes the same symptom at campaign level. Tight location targeting, a short ad schedule or a small audience all shrink the pool of auctions, which is the Inventory factor Google flags when a bid strategy is limited by available search volume.

How to Read Impression Share Lost to Budget and Rank

Impression share lost to budget and lost to rank show whether a campaign is held back by money or by how competitive its ads are in the auction. Google’s guide to impression share defines it as the impressions your ads receive divided by the total impressions they were eligible to get. Eligibility is estimated from targeting settings, approval statuses and quality.

Two columns split the missing share by cause. Google’s instructions for getting impression share data define Search lost IS (budget) as the percentage of time ads did not show on the Search Network because of insufficient budget. Search lost IS (rank) is the percentage of time they did not show because of poor Ad Rank.

The two columns sit under Competitive metrics in the column picker. Search lost IS (budget) is only available at campaign level, so budget questions have to be answered campaign by campaign.

A high lost IS (budget) with a low lost IS (rank) points to a budget problem. The campaign is competitive when it shows, so a larger budget or a tighter spread of keywords and locations would win more of the auctions it is already good enough to enter.

A high lost IS (rank) points to an Ad Rank problem that more budget will not solve. Google’s definition of Ad Rank includes the bid, the quality of the ads and landing pages, the competitiveness of the auction and the context of the search. Our guide on how to improve Google Ads Quality Score covers the quality side in more detail.

Google’s tips for improving impression share list higher budgets and higher bids alongside better ad quality. They also point out that widening location targets adds potential impressions, which can lower impression share unless the budget rises with it.

What to Do When a Campaign Is Limited by Budget

The fix for Limited by budget is to give the campaign more budget or to ask it to cover less ground with the budget it already has. The right route comes down to whether the extra traffic is worth paying for.

Google’s tips for optimising an average daily budget include lowering bids slightly in campaigns marked limited by budget, which can reduce the average cost of each click so the budget stretches further. Google warns that lowering bids too far can cut clicks once bids stop being competitive, so check the campaign again a few days after any change.

Google also shows a recommended budget for campaigns that regularly reach their average daily budget but could earn more clicks and impressions. The budget simulator in the campaigns table estimates how much more exposure a different budget might bring, which gives a starting point for deciding whether more spend is justified.

Campaign structure plays a part as well. Separate campaigns for brand terms, core services and lower value searches let each one carry a budget that matches its value, rather than one budget being spent on whichever searches arrive first. Our guide to Google Ads campaign structure for B2B sets out how to split campaigns along those lines.

Budget changes also move spend from day to day. Google’s page on overdelivery and the average daily budget explains that a campaign can spend more than its average daily budget on a given day to make use of changes in traffic, while the month as a whole stays within a monthly limit. A day that overspends is not a sign that the budget has been raised. A quiet day is not a sign that the campaign is broken either.

When a Limited Status Needs No Action

A limited status needs no action when the campaign is meeting its goals and the limit is expected. Google says a campaign that is limited by budget can still be successful and meet advertising goals, even though it is likely missing some impressions, clicks and conversions.

Some budgets are deliberately capped. A campaign covering lower priority searches can sit at Limited by budget for months while most of the budget goes where it earns the most. Eligible (Limited) on a certified gambling advertiser’s ad is simply how Google expects that ad to run.

Google also notes that Eligible (Limited) is sometimes shown as a recommendation. Where performance is good, dismissing the recommendation may clear the status within a day or two.

What matters is knowing which status is which and checking them on a schedule rather than only when results dip. Priority Pixels reviews campaign structure, keyword match types, bidding strategies and conversion tracking setup when it audits an existing Google Ads account. Our guide to what to expect from a Google Ads audit covers what a full review of an account should include.
