How much does Google Ads cost and what budget should you choose?

Last updated: 2026-09-16

Search is often a better fit to start with for services with clear search demand. This applies when a potential client types the name of a specific service or a description of a problem and expects a directly matching answer. However, this is a practical recommendation, not a rule for every industry, location and budget level.^[7][8]

Performance Max is best treated as a next step, once a business can reliably measure results and feed the campaign the right data. Official Google materials don't set a single budget threshold or number of conversions beyond which the campaign becomes the right choice.^[1][3][4]

Choose Search to start

When customers are actively searching for specific services, the business needs control over search queries and wants to put tracking in order first.

Consider Performance Max

When conversion goals are correctly defined, lead quality can be assessed and the business has the landing pages and assets needed to run the campaign.

Combine both campaign types

When Search handles specific demand for services and Performance Max is to play a controlled, expanding role.

Hold off on the decision to scale

When the report shows only the number of contacts but doesn't let you determine which of them were valuable.

Before choosing a campaign, you need to answer three questions: are customers searching for a specific service, does the business have its own definition of a qualified lead, and can it check what happened after a form submission or phone call? If tracking ends at the contact itself, more automation won't solve the lack of data.

Search focuses on queries users type into the search engine. Performance Max is a goal-based campaign that can use many Google inventories, including Search, YouTube, Display, Discover, Gmail and Maps. The availability of a specific inventory, however, depends on the campaign's goal, settings and eligibility. It also doesn't mean the budget is spread evenly across the channels.^[1][2]

When Search matches the way people look for a service

Search is a justified direction when the offer responds to a recognizable need and the user can name the service or problem. The popularity of queries alone, however, doesn't settle the quality of demand. The fit of the offer, the service area and whether the page responds to the intent of the person clicking the ad also matter.

The ad message and the page content should form a consistent path. A separate preparation step can be a service page for Google Ads campaigns, because the campaign type won't replace a clear description of the service and the way to get in touch.

What Performance Max automates

Performance Max hands a bigger share of decisions on bids, targeting and asset use to Google's automation. The mechanism uses the goals set and conversion data, but it doesn't guarantee a business result. How it works depends on the quality of the goals, data, creatives and tracking configuration.^[1][3]

Greater reach shouldn't be a standalone argument for choosing Performance Max. The business also has to know which user actions are valuable to it and how to tell a real quote request from a random or ill-matched contact.

Performance Max is justified when the system can receive signals as close as possible to real business value. For lead campaigns, Google recommends using clearly defined goals and valuable conversions, such as a qualified or converted lead. However, setting up a goal alone doesn't guarantee that the contacts acquired will be valuable.^[4]

A conversion isn't always a valuable lead

A technical conversion can be a form submission, a click on the phone number or another recorded action. A qualified lead, on the other hand, is a contact that meets criteria set by the business. A sale is a further stage still. These three levels should be reported separately, although expert sources don't present one methodology suitable for all service businesses.^[7][8]

Organizing technical events can include contact form conversion tracking, but recording a form submission still doesn't answer whether the contact matched the offer and ended with a sale.

The data worth passing to optimization

In Performance Max, conversion data is part of the signal steering optimization. If an action unrelated to real value is set as the primary goal, the system may optimize the campaign for easier contacts instead of the ones the business considers valuable.^[1][3][4]

Defining a conversion

The business knows which actions are merely a technical signal and which mean a valuable contact.

Qualification criteria

You can determine whether the lead concerns the right service, location and scope of the offer.

Information from a later stage

The business can mark the outcome of the contact, e.g. qualification or a sale. This doesn't mean every business has to use a CRM.

Conversion value

If used, it should reflect the real hierarchy of the value of actions, not arbitrary amounts.

Website and ad assets

The offer, landing page and assets provided to the campaign are ready to use.

The lack of an official, universal minimum of data, budget or conversions means that readiness for Performance Max shouldn't be judged by a single number. A safer criterion is the ability to recognize a valuable result and pass that information to the optimization process.

Yes, both campaign types can work together. However, they should have separate roles, and the business must control brand-related traffic, unwanted queries and the quality of leads from each campaign.

Search and Performance Max aren't completely separated. Google describes the rules for prioritizing them, and campaign settings and budget constraints can affect auction participation. These rules don't automatically create a quality-based split of leads, so campaign overlap has to be assessed based on the account's configuration and data.^[1]

Brand traffic and brand exclusions

Brand traffic covers queries containing the name of the company or brand. When combining campaigns, you need to decide whether such traffic should be handled separately and plan the control of unwanted queries. For this purpose, Google provides, among other things, brand exclusions and negative keywords.^[5][6]

Brand exclusions aren't the same as a regular negative keyword list. They can cover variants of the brand name, but their use requires caution: settings that are too broad can also limit some valuable traffic. They also don't provide a complete manual split of all queries between campaigns.

A staged rollout model

1. Define the role of Search. Assign it specific services and queries that correspond to active demand.
2. Organize conversion goals. Separate technical actions from qualified leads and the sales result.
3. Define the role of Performance Max. Treat it as a controlled expansion test, not an automatic replacement for Search.
4. Set rules for brand traffic. Assess the need for brand exclusions and unwanted queries, taking into account the risk of limiting valuable reach.
5. Compare quality, not just volume. Analyze which campaigns deliver contacts that move on to further sales stages.

Before expanding reach, a website audit before ads and SEO can also be useful. It lets you assess the readiness of the destination separately, without attributing every problem to the campaign type itself.

The accuracy of the choice should be assessed at the level of qualified leads and sales, not just the number of conversions visible in Google Ads. The specific metrics depend on the sales process, the way of contact and the data available in the business.

If Performance Max increases the number of reported conversions but doesn't improve the number of qualified leads or sales, you need to reassess the conversion goals, input data and the campaign's role. Such a result doesn't automatically mean that the campaign type itself is wrong.

There's no single benchmark result that fits every service. The outcome depends on factors such as the specifics of the industry, location, sales process, demand, landing page, ad assets and data quality. For this reason, the advantage of Search or Performance Max shouldn't be declared based solely on a change in the number of technical conversions.
