Should B2B software companies choose Search or Performance Max?

Search vs Performance Max: for B2B software, start with a Search campaign on buying intent. Your market is small, a click quickly costs tens of dollars and you want to justify every keyword. Only add Performance Max once you feed qualified leads from your CRM back to Google. Then it is an add-on for extra reach, not a replacement.

Your Google rep suggests Performance Max, or your budget is going up and you are unsure which campaign type should get it. If PMax already brings you mostly junk leads, read our guide to Performance Max campaigns first. Here we put the two side by side and say when to choose which. The wider context is in what SEA is.

Performance Max or Search campaigns for B2B software?

Choose Search first. Three reasons make it almost always the right start for B2B software.

• Clicks are expensive. Across 106 search terms from Benelux software categories, a click costs a median of about 22 dollars (Google Ads data, September 2026). For “crm software” it is about 39 dollars in the Netherlands and 26 dollars in Belgium. A click on an irrelevant placement really costs you money.
• Demand is small and sharp. Few people search for your category, but those who do want to buy. With keywords like “[category] software”, “[competitor] alternative” and “compare [category]” you catch exactly those people.
• PMax needs data you often do not have yet. With a handful of demos a month, the algorithm does not know what a good lead is.

Performance Max becomes interesting when Search exhausts your buying-intent volume and you feed back qualified leads. Then set it up with its own budget and measure it on pipeline, not on forms. What a click costs in your sector is in our CPC benchmarks by industry.

What does a Search campaign do?

A Search campaign shows text ads in the search results at the moment someone searches for a term you chose. You decide the keywords, the copy and the landing page. Someone searches for “accounting software for SMEs”, your ad appears and the click leads to your page.

Its strength is intent. In B2B, search volume is often low but buying intent is high. You choose which terms you show up for and which you exclude, and you see which keyword produced which conversion.

The downside: Search is capped by search volume. If nobody searches for what you offer, there is nothing to bid on. And it needs upkeep, because keywords, bids and exclusions have to stay right.

What does Performance Max do?

Performance Max, or PMax, works the other way round. You give Google a goal, assets (copy, images, video) and your conversion data. The algorithm decides where you show up: on Search, YouTube, Display, Discover, Gmail and Maps. One campaign, every channel.

You trade control for reach and automation. You are no longer completely blind, though. Google now offers a search terms report for Performance Max, and you can block irrelevant terms. Negative keywords there only apply to Search and Shopping placements. Which channel produced a conversion stays less visible than in Search.

Why does Performance Max run on your conversion data?

Performance Max is exactly as good as the conversion data you put into it. Let it optimise for a form or a download and it gets very good at bringing in forms. Including from people who will never become customers. Your dashboard turns green, but sales gets junk.

The fix is to make your data smarter. Send back which lead became qualified, which opportunity became a deal and what that deal was worth. How that works is in importing offline conversions from your CRM. Then PMax optimises for leads that turn into revenue. The basics are in Google Ads conversion tracking.

The same goes for Search, but you feel the pain there more slowly. Because you pick the keywords yourself, you already filter out a lot of noise. With PMax that human filter largely disappears, so your conversion signal becomes the main steering wheel. You do not have to give up your grip entirely: with brand exclusions, search themes and exclusions you keep control over Performance Max.

When do you choose Search and when Performance Max?

In most B2B projects, Search is the backbone. Demand is targeted and you want to justify every euro. A well-built Google Ads campaign on Search often delivers the cleanest leads. Launch PMax too early or with weak data and it works against you.

Can you run Search and Performance Max together?

Yes, and Google designs PMax as a complement to your Search campaigns. Worth knowing: a Search campaign with an exact match keyword takes priority over Performance Max when the query matches it. Search themes in PMax carry the same priority as phrase and broad match.

In practice, put your most important buying-intent terms on exact match in Search. PMax picks up the demand Search does not see. Exclude your brand name in PMax, or it claims the cheap brand conversions and looks better than it is. Steer both on the same lead-to-deal data.

When we are not the right choice

Do you sell to consumers with high volume and a quick purchase? Then Performance Max can work fine without a CRM link, and you do not need us. If you only want someone to set up campaigns without looking at your pipeline, another agency is a better fit. As a Google Ads agency we steer Search and Performance Max on qualified leads and deals. Tell us your goal, your search volume and how you measure today, and we will tell you honestly which combination fits. Get in touch.
