Google Ads campaign structure in Bangalore: how many campaigns and ad groups a small budget can feed

If you are spending under ₹40,000 a month in Bangalore, you need one or two Search campaigns, with three to six ad groups between them. The ceiling is not how many campaigns Google lets you build. It is how much conversion data each one collects, and an ad group seeing fewer than about 15 conversions a month gives automated bidding nothing to learn from.

Almost every small account we are asked to rescue has the opposite problem. Somebody built a campaign for every service on the website because it looked organised in the interface, and now nine campaigns are sharing the budget of one.

How many campaigns can a small budget support?

Start from clicks, not from your service list. A ₹30,000 monthly budget is ₹1,000 a day. Commercial service keywords in Bangalore were clearing between ₹45 and ₹90 a click through the first half of 2026, higher for legal, dental and cosmetic terms. That gives the entire account 11 to 22 clicks a day. Split those across five campaigns and each one gets two or three clicks, which is not enough for the bidding system to form an opinion about anything.

Of 26 Bangalore accounts under ₹50,000 a month that we reviewed between January and June 2026, 17 were running four or more Search campaigns. Their median cost per lead was ₹1,180. The nine running one or two campaigns sat at ₹740 for comparable services.

Why extra campaigns make results worse

Three things go wrong at once. The daily budget gets divided until no campaign has enough to reach the auctions it should win. Each campaign restarts its learning period after every meaningful edit, and a campaign with four conversions a month never really leaves it. And campaigns holding overlapping keywords end up in the same auction, where Google picks one and the rest just add reporting noise.

A dental practice in Jayanagar ran six campaigns split by treatment in February 2026, each capped at ₹150 a day. Four of them never exited the learning phase in eleven weeks. Consolidating to two campaigns in April, one for implants and one for general dentistry, brought cost per booked consultation from ₹1,620 to ₹910 over the following seven weeks on the same total spend. Rakesh, who runs the practice, said the part that convinced him was seeing that his implant ads had been offline most afternoons because the budget was gone by lunch.

How many ad groups, and how many keywords in each?

Two or three ad groups per campaign is the right starting point at this budget, each holding three to five closely related keywords pointing at one landing page. Large accounts run seven to ten ad groups per Search campaign, and that range is fine when there are conversions to fill them.

The test for whether two keywords belong together is simple. If they would take the same ad headline and the same landing page, keep them in one ad group. If one needs a different page, it needs its own ad group. Keyword lists that mix "root canal cost Bangalore" with "emergency dentist near me" fail that test, because the person searching each one wants a different page.

When is a campaign ready to be split?

Split when the segment is already producing about 15 conversions a month on its own, or when it needs a budget guardrail you cannot enforce any other way. Different cities, different languages, and offers with very different values are the usual reasons. Wanting a tidier account is not a reason. A split you make early costs you the data you needed to justify it.

What about Performance Max on a small budget?

For a service business under ₹40,000 a month with no product feed, put Search first and add Performance Max later, once Search is losing impressions to budget rather than to relevance. Across those same 26 accounts, the seven running Performance Max alongside Search took a median 62 percent of total spend into PMax and got 31 percent of the leads back from it. That trade only makes sense once your Search campaigns are already capped out.

The settings that undo a good structure anyway

A clean structure still leaks if the defaults were left as Google set them. Search Partners, Display expansion on a Search campaign, and broad location targeting will all pull spend away from the queries you built the structure around. We went through the nine Google Ads default settings that quietly spend your budget earlier this month, and it is worth checking those before you touch the campaign count.

What it costs to set this up properly

Restructuring an account is a few hours of work, not a retainer's worth. Studio Happens keeps performance marketing priced for businesses running small budgets, because a ₹25,000 account that is structured well outperforms a ₹60,000 account that is not, and there is no honest reason to charge agency retainer rates for a rebuild that takes an afternoon.

Frequently asked questions

How many keywords should one ad group have?

Three to five for a small account. Every keyword in the group should be answerable by the same ad and the same landing page. More than about ten, and the ad copy stops matching what people typed, which pushes your Quality Score down and your cost per click up.

Should every service have its own campaign?

No. Give a service its own campaign when it already earns roughly 15 conversions a month or needs a separate budget cap. Below that, keep it as an ad group inside a larger campaign so the bidding has enough data to work with.

Is one campaign ever enough?

Often, yes. Under about ₹20,000 a month, one Search campaign with two or three ad groups is usually the structure that produces the lowest cost per lead in Bangalore. Add the second campaign when the first is losing impression share to budget.
