Should I Increase My Google Ads Budget? What Changed on September 24, 2026

If you run Google Ads, you have probably been asked this question by the platform itself: should I increase my Google Ads budget? Google has started answering it for you, twice, and on the same day. On September 24, 2026, two changes landed in the same account. One ties the budget-increase prompt to a projected weekly conversion value whenever a campaign is marked budget-limited. The other adds Holistic and Growth modes to the Recommended Investment Strategy, which reallocate or add budget automatically without asking first. Both are sales prompts wearing an optimization label. Neither one knows what a booked job costs you.

Here is what each feature does, why accepting it on faith raises your cost per booked job more often than it lowers it, and the one check to run before you click accept this month.

What changed on September 24, 2026

Two separate updates went live the same day, both reported by Search Engine Roundtable:

• Budget-increase prompts now show a projected weekly conversion value. When a campaign is flagged as budget-limited, the recommendation panel forecasts how much more conversion value you would get by raising the daily budget, framed as a specific number rather than a vague nudge. (seroundtable.com, Sept 24 2026)
• The Recommended Investment Strategy added Holistic and Growth modes. Holistic mode reallocates existing budget across campaigns based on where Google’s models see the best return. Growth mode goes further and adds budget on top, not just moving it around. Both can act with less manual sign-off than the standard bidding recommendations most owners are used to reviewing.

Individually, either change sounds like Google getting smarter about spend. Together they mean the platform now has a cleaner story to tell you about why you should spend more, and a faster way to spend it once you agree.

Should I increase my Google Ads budget just because Google says to?

Not automatically, and not on the forecast alone. The conversion forecast is a real number, calculated from real signals in your account. It is not a guess pulled out of the air. But it answers a narrower question than the one you actually care about. It tells you what more budget could produce in conversions inside Google’s own tracking. It does not tell you what happens to those conversions after they leave the ad and land in your business.

A conversion in Google Ads is usually a form fill, a call click, or a booking widget submission. A booked job is something that happened after that: someone answered the phone, someone followed up within the hour, someone quoted the work and the customer said yes. Google’s forecast stops at the first event. Your P&L cares about the last one.

This is the gap that makes the question worth asking properly instead of clicking accept. Raising budget on a campaign that is already converting well and following up well is often the right call. Raising budget on a campaign that is generating leads your team is slow to call back just buys you more leads that go cold, at a higher total spend.

What the conversion forecast actually measures

The forecast is built from the campaign’s own recent conversion rate, your current bid strategy, and the auction pressure Google is seeing on your keywords right now. It is a reasonable extrapolation of recent performance, scaled up. What it cannot see:

• Whether your CRM logged the lead and assigned it to someone within minutes, or whether it sat in an inbox until the next morning.
• Whether the lead that converts at a higher rate is also the lead that shows up, is a good fit, and pays the invoice.
• Whether a second campaign, one that is not flagged as budget-limited, is quietly producing your cheapest booked jobs while the flagged one produces your most expensive.

None of that is a criticism of the forecast. It is doing exactly what it was built to do: estimate more conversions from more spend inside the auction. The mistake is treating a Google Ads budget recommendation as a business decision instead of what it actually is, which is an auction-level estimate with no visibility into your calendar.

What Holistic and Growth modes do to your account

The Recommended Investment Strategy already existed before September 2026. What changed is the addition of two modes that act with less friction:

• Holistic mode moves budget between your existing campaigns toward whichever one Google’s model currently favours. If Campaign A is producing cheap leads that never turn into booked jobs, and Campaign B is producing fewer, better leads, Holistic mode can still shift budget toward A if A’s on-platform conversion signals look stronger. It has no way to know which campaign your team actually closes.
• Growth mode does not just reallocate, it adds. It is the automated version of accepting every budget-increase prompt in the account at once, on an ongoing basis, without a human reading the forecast each time.

For an owner managing one account part-time, automation that removes a manual step sounds like a win. It is a win, right up until the automated reallocation starts favouring the campaign with the worst follow-up, because follow-up is not a signal Google Ads measures.

Why the forecast can be right and your cost per booked job can still go up

This is the part worth sitting with before the next prompt shows up. The forecast can be completely accurate about conversion volume and value inside Google Ads, and your cost per booked job can still climb, because those are two different numbers measuring two different points in the funnel.

Take a real pattern we see across trades and clinic accounts: a campaign converts at $146 per lead, right in line with account averages. Budget doubles on Google’s recommendation. Lead volume doubles too, exactly as forecast. But the front desk was already stretched thin handling the original volume. Response time on the new leads slips from under five minutes to over two hours. Show rates drop. The cost per lead stayed the same. The cost per booked job went up, because more of those leads never became jobs.

Google Ads has no line item for that. It cannot see your call tracking, your CRM’s response-time log, or your close rate by lead source. The forecast is honest about what it measures. It is silent about what it does not.

The one check to run before you click accept

Before accepting a budget-increase prompt or turning on Growth mode, pull one report: cost per booked job by campaign, for the last 60 to 90 days, cross-referenced against average lead response time for that same campaign. Not cost per lead. Not conversion rate inside Google Ads. Cost per booked job, tied to actual jobs on the calendar or invoices issued.

If the flagged campaign already has a fast, consistent follow-up process and a cost per booked job that is at or below your account average, the increase is probably a reasonable bet. If response time is slow, if the campaign’s leads convert to jobs at a lower rate than others in the account, or if you cannot answer the question at all because lead source and job outcome are not connected in your CRM, fix that connection first. Adding spend to a campaign with a follow-up problem does not fix the follow-up problem. It just makes it more expensive.

This is the same principle behind fixing conversion and follow-up before increasing ad spend generally, and it applies with more force now that Google is making it easier to increase spend without a second look. The platform’s forecast and your business outcome are not the same measurement. Treat the prompt as one input, not the decision.

If your account is already reporting cost per booked job by campaign, this check takes ten minutes. If it is not, that gap is worth closing before the next Growth mode nudge or budget prompt, not after. Our Google & Meta Ads work is built around exactly this: campaigns reported on cost per booked job, not cost per lead, with the follow-up system checked before spend goes up.

Book a call before you accept the next Google Ads budget recommendation. We will look at your account, your response times, and what a booked job actually costs you by campaign, and tell you plainly whether the increase Google is suggesting is one worth taking.
