What "Limited by bid strategy" and "Eligible (Limited)" mean, the four real causes, the 5-step fix, and when ignoring the warning is the right call.
"Limited" in the bid strategy column means your automated strategy is running, but something (usually a bid limit or an aggressive Target CPA/ROAS) is keeping it out of auctions it could otherwise win. It is not the same as "Limited by budget", and it does not always need a fix. Hover the status for the specific cause, then decide.
"Bid Strategy Limited" tells you the strategy is active but constrained. The auction algorithm wants to bid higher (or relax a target) and the settings you chose are preventing that.
The fastest first check: open the Status column in your Campaigns table and hover the warning. Google names the specific limiting factor right there.
Bid strategy status is an indicator in Google Ads that shows whether your automated bidding strategy can operate without obstruction. The full official list is short.
Learning and Limited get confused often. Learning is temporary and expected, usually for the first one to two weeks after a change. Limited is structural and stays until you adjust the underlying setting (or accept it on purpose).
Three labels in the interface look almost identical and mean different things. This is where most accounts misdiagnose the problem.
| Status label | What it means in one line | Where to look |
|---|---|---|
| Eligible (Limited) | Campaign is in the auction. One or more factors are dampening performance. | Campaign Status column |
| Limited by bid strategy | The automated bid strategy itself is constrained (bid limits or target). | Bid strategy column |
| Limited by budget | Daily budget is too low for the campaign's bid level and demand. | Campaign Status column |
Eligible (Limited) is the umbrella. Limited by bid strategy is one of the things that can live under that umbrella, alongside low search volume, low ad strength, and the budget issue. "Limited by budget" is its own separate label with its own Google Ads fix guide, and we wrote a deep dive on the budget side in Google Ads not spending full budget. Mixing the two up is the number one reason advertisers raise budgets when their bid limits were the real problem.
Four causes cover roughly 95% of cases.
Bid limits set too narrow. You attached a Max CPC bid limit (or a min) to a portfolio or standard strategy. The algorithm wants to bid above the ceiling to win, the ceiling holds, and a chunk of impressions slips by. Concrete shape: bid limit set at $1.50, the median winning bid in the niche is closer to $2.40, and your impression share lost to rank sits at 90%-plus. The lid, not the demand, is the problem. If raising the ceiling produces runaway CPC instead, the auction is the wrong shape, and the playbook in Google Ads cost per click too high covers the nine causes behind that.
Target set too aggressively. Target CPA below the account's real CPA, or Target ROAS above what the account has historically achieved. The strategy refuses to buy traffic it predicts will miss the target. The direction matters: for Target CPA the trouble is "too low"; for Target ROAS the trouble is "too high". Both create the same outcome, which is a strategy that holds back. If your ROAS dropped before the warning appeared, the trigger may be upstream of bidding (see Google Ads ROAS dropped suddenly).
Conversion volume too low for Smart Bidding. Smart Bidding strategies (Target CPA, Target ROAS, Maximize Conversions, Maximize Conversion Value) get better with more data. With very few conversions, the algorithm leans defensive and underbids. Google does not publish a hard threshold. The industry rule of thumb is roughly 30 to 50 conversions per month per campaign before Target CPA or Target ROAS settles in, and Google itself only says to measure performance after enough data has accumulated. Volume that low can also be a tracking artifact: if a tag is dropping fires, the algorithm sees a starved campaign that is actually converting fine. Google Ads conversion tracking not working walks through the 90-second triage.
Structural conflicts and recent disruption. Targeting set too narrowly (a single ZIP code, a single device, an exotic language). A shared budget where the strategies don't match the policy that all campaigns in a shared budget must use identical portfolio strategies. A change you made yesterday that is still inside the learning window. These look like "Limited" too, even though the cause is different.
Diagnosis takes about two minutes in the interface, before you change anything.
A simple interpretive rule covers most cases. If your actual CPA is well below the target and spend hits a bid ceiling, the ceiling is the problem. If the target is more aggressive than the account's history, the target is the problem. If conversions are under roughly 30 per month, the data volume is the problem.
The fix depends on the cause. There is no single button.
The "Limited" status does not always require action. Sometimes it is the strategy working as designed.
Three scenarios where ignoring it is correct:
Practitioners on r/PPC reach the same conclusion: review the alert, then generally do not act on it unless results are off. Agency blogs that paint every yellow status as an emergency rely on the panic. Status warnings are signals, not verdicts. If you are also questioning whether to keep paying for that agency in the first place, the framework in Google Ads without an agency is built for exactly this stage.
Bid limits drift. Targets that were correct in March become tight by July as auction prices rise and seasonality shifts. Catching this manually means logging in, reading hover tooltips, comparing 30-day averages, and deciding. Every week. Across every campaign.
B6 is an AI agency that lives inside the cabinet. The agents do the watching and the comparing, then show their reasoning before they apply anything. Buzz tracks bid limits and impression share. Maximus keeps Target CPA and Target ROAS aligned with the account's profitability bands. Aegis reviews any risky change before it goes live. Echo packages the week into a digest you can read in three minutes. It is not "AI advises". It is "AI does, and shows every step".
Pricing is straightforward: $99 Co-pilot, $199 Approval, $399 Autonomous. No setup fees. See B6 pricing.

What does "limited by bid strategy" mean?
It means your automated bid strategy is operating, but a setting (usually a Max CPC bid limit or an aggressive Target CPA/ROAS) is preventing it from winning auctions it would otherwise win. The strategy is active, not stopped.
What is "limited by bidding target"?
It is one specific cause inside "Limited by bid strategy". The target you set is too aggressive for the account's recent performance, so the algorithm refuses to bid into auctions it predicts will miss the target.
How long does the Google Ads bid strategy learning phase take?
Google does not publish a fixed duration. The industry rule of thumb is 7 to 14 days for Search campaigns, and roughly 30 to 50 conversions before Target CPA or Target ROAS stabilizes. Treat these as ranges, not guarantees.
What is a maximum bid strategy / Max CPC bid limit?
A ceiling you can attach to portfolio or standard strategies that caps how high the system can bid. It exists to protect against runaway CPC. The trade-off is that a ceiling too low produces the "Limited by bid strategy" warning.
Is "Eligible (Limited)" bad, should I worry about it?
Not by itself. Eligible (Limited) just means the campaign is in the auction and one or more factors are dampening reach. Hover the status for the specific factor, then judge whether that factor is actually a problem given your goals.
How is "Limited by bid strategy" different from "Limited by budget"?
"Limited by budget" means the daily budget is too low for the campaign's bid level and demand (Google Ads Help). "Limited by bid strategy" means the bid strategy itself, not the budget, is the constraint. Same word, different problem, different fix.
Can I just ignore the "Limited" status?
Often yes, if results are on plan. If the strategy reflects deliberate margin discipline, the warning is the price of that discipline. Ignore the label, watch CPA, conversions, and profit instead.
Connect your Google Ads account. On the first run, B6 surfaces every campaign with a bid-limit or target-induced "Limited" status, ranks them by potential impact on CPA, and proposes the change. You approve, B6 applies. See how Buzz handles bidding, or jump straight to B6 pricing.
Connect Google Ads, and B6 surfaces every campaign where a bid limit or target is the actual constraint, with a one-click revertable fix attached to each.
