The September 2026 Paid Media Round-Up: What B2B Marketers Need to Know

Paid media platforms are becoming increasingly automated.

Google is giving its systems more control over bidding, targeting and campaign setup, while Meta is putting more emphasis on the creative itself when deciding who sees an ad.

For B2B marketers, that means the role of paid media is changing too.

September brought a few updates that caught our attention and, more importantly, raised some interesting questions. What does paid media look like when platforms take care of more of the mechanics?

Google Ads: More campaigns are moving to AI Max

September marked the start of Google's automatic migration of certain Search campaigns to AI Max.

From 1st September, Google began progressively upgrading campaigns using campaign-level broad match or standalone Automatically Created Assets to AI Max. The migration is taking place throughout September, with Dynamic Search Ads following a separate migration process in February 2027.

It's another step towards Google taking more responsibility for how Search campaigns are managed and optimised.

As platforms become better at handling the tactical side of campaign management, the things marketers control directly, such as conversion signals, creative, landing pages, messaging and measurement, become increasingly important.

What should you do?

If your campaigns have been migrated, don't assume that "AI" means you can leave them alone.

Review performance before and after the change and look at the metrics that matter to the business.

That means going beyond clicks and conversions to consider:

• Lead quality

• Cost per qualified lead

• MQLs and opportunities

• Pipeline generated

• Revenue, where you can track it

It's also worth checking your conversion actions. If Google is being given more control over optimisation, you need to make sure you're giving it the right signals to optimise towards.

Google Ads: Language targeting is changing

Another Google Ads change that took effect in September is the removal of campaign-level language targeting for Search and AI Max for Search campaigns.

Instead, Google will use the language of the ads as part of its matching process. For Performance Max, campaign-level language targeting will still apply across some channels, but will no longer be used for ads shown on Google Search.

On the surface, this might seem like a relatively minor campaign-setting change.

But it's another example of Google removing manual controls and relying more heavily on its automated systems to determine relevance.

For international B2B campaigns in particular, it's worth understanding how this affects your account rather than assuming your previous targeting setup is still working in exactly the same way.

What should you do?

If you're running multilingual campaigns, check your ad and landing page language carefully.

Make sure:

• Ads are clearly written in the intended language

• Landing pages match the language of the ads

• Your international campaign structure still makes sense

• Performance is monitored separately across markets where appropriate

The broader takeaway is the same as with AI Max: the platforms are making more decisions automatically, so marketers need to pay closer attention to the signals those systems are using.

Meta: Is the creative becoming the targeting?

Meta is testing a new approach to audience targeting that allows some advertisers to add audience suggestions at the ad level, rather than the ad-set level.

At the moment, the test allows advertisers to suggest an age and gender for an individual ad. Meta can then use those suggestions as signals when deciding who should see it.

It's an interesting development because Meta is already putting a huge amount of emphasis on the creative when deciding who is likely to respond.

So, rather than thinking about targeting and creative as two completely separate parts of a campaign, we're moving towards a world where the creative itself can help determine the audience.

For B2B marketers, that could have some interesting implications.

If the platform is increasingly responsible for finding the right people, the job of the creative is not simply to make someone stop scrolling.

It needs to clearly communicate who the product is for, what problem it solves and why it's relevant.

What should you do?

Don't abandon audience strategy but start thinking more carefully about the role your creative plays in communicating audience relevance.

Test different:

• Pain points

• Industry-specific messaging

• Job-role hooks

• Use cases

• Value propositions

The more clearly your creative communicates the audience and problem it's relevant to, the more useful it can potentially be as a signal to the platform.

What can B2B marketers take from September?

The biggest theme running through this month's paid media updates is automation.

Google is giving AI Max more control over Search campaigns and reducing some of the manual settings advertisers have historically managed. Meta is increasingly using creative as a signal when deciding who should see an ad.

That doesn't mean marketers are becoming less important.

It means the job is changing.

When platforms handle more of the mechanics, marketers have more reason to focus on the things that platforms can't understand as easily: strategy, positioning, creative ideas, audience insight and commercial context.

That final point is particularly important for B2B.

The platform might be able to optimise towards a conversion.

It can't know whether that conversion is going to become a £5k opportunity, a £50k opportunity or nothing at all unless you're giving it the right signals.

As we head into Q4, it's worth asking:

Are your paid media campaigns optimised for what the platform can measure or what your business actually values?

We'll be back next month with another round-up of the paid media changes and updates worth knowing about.
