What May’s Paid Media Changes Mean for AI Search, Automation and Full-Funnel Advertising

May reinforced how quickly paid media platforms are moving towards AI-led campaign delivery, automated creative production and broader discovery environments. Across Google, Meta and TikTok, the major updates all point in the same direction: advertisers are being given more ways to reach people across search, social, commerce and video-led discovery, but more campaign decisions are being handled by automated systems.

For advertisers, the opportunity is scale. Campaigns can reach users across more placements, formats and moments of intent than before. But this also makes campaign quality, tracking, creative inputs and reporting frameworks more important.

The practical challenge is no longer only how campaigns are set up. It is whether advertisers are giving the platforms enough high-quality signals to make automation work effectively.

In Short: What Matters This Month

• Google Marketing Live 2026 showed how far Google is moving into AI-led advertising across Search, YouTube, Shopping, measurement and creative production.
• AI Search ad formats are becoming more conversational, meaning advertisers may need to think beyond traditional text ad placements and keyword-led performance.
• Meta is projected to overtake Google in global ad revenue, reinforcing its position as a major performance platform, not just a social awareness channel.
• Meta’s May rollouts point to more AI-assisted setup across lead forms, Pixel settings, creative generation and retargeting controls.
• AI referral traffic, AI shopping growth and AI Overview CTR studies

For most advertisers, the key message is that automation is not removing the need for paid media management. It is changing where that management effort needs to sit. Strong campaign inputs, clean tracking, useful creative, clear reporting and proper quality assurance are becoming more important, not less.

Paid Media Is Moving Deeper Into AI-Led Discovery

Business Impact

Advertisers are likely to see more campaign delivery shaped by AI-led formats, automated optimisation and cross-platform discovery journeys.

This creates an opportunity to reach users in more relevant moments, especially across Search, YouTube, Shopping and AI-led placements. However, it also means advertisers may have less control over every individual query, placement or creative variation.

The practical challenge is making sure the platform has strong enough inputs to guide automation properly. Product feeds, landing pages, audience signals, creative assets and conversion data will all play a bigger role in campaign performance.

Google Marketing Live 2026 expanded Google’s AI advertising roadmap

What happened

At Google Marketing Live on 20 May 2026, Google announced a wider set of AI-powered ad and commerce updates across Search, YouTube, Shopping and measurement.

Key announcements included new ad formats built for AI Search, further AI Max expansion, Ask Advisor as an AI collaborator across Google Ads, Google Analytics, Merchant Centre and Google Marketing Platform, plus new AI creative tools in Asset Studio.

Why this matters

Google is moving paid media further into AI-led discovery, creative generation, automated optimisation and agentic commerce.

This means advertisers may have less manual control over every individual placement or query, but more opportunity to appear across conversational, visual and shopping-led journeys if their campaign inputs are strong.

This also means reporting needs to evolve. Advertisers should not only be looking at traditional keyword performance, but also how Search, YouTube, Shopping and AI-led placements work together across the customer journey.

What advertisers should be paying attention to

Advertisers should review whether Search campaigns are ready for AI Max and broader query matching.

Product feeds, landing pages, creative assets and audience signals should be strengthened, as these are becoming more important inputs for automated campaign delivery.

New AI Search and Demand Gen opportunities should be tested carefully, rather than waiting for automatic adoption. Reporting frameworks should also be reviewed so performance is assessed across Search, YouTube, Shopping and AI-led placements, not only traditional keyword activity.

Search Is Becoming More Conversational

Business Impact

Paid search is becoming less about serving a standard ad against a typed keyword and more about appearing within assisted, conversational search journeys.

This could affect how users interact with ads before reaching a website. A user may now engage with AI-generated answers, product information, comparisons and recommendations before seeing or clicking a traditional search result.

For advertisers, this means search performance may become more fragmented across impressions, assisted interactions, product visibility and conversion paths.

Google is introducing ad formats built for AI Search

What happened

Google introduced new ad formats designed for the AI era of Search, including ads that can sit more naturally inside AI-led responses and shopping journeys.

Google described these formats as being tailored to a user’s specific query, offering more context to help users move from question to purchase.

Why this matters

This continues the shift from traditional text ad results into a more assisted, conversational search experience.

Users may interact with Google’s AI-generated answers, product explainers and recommendations before reaching the standard search results page. This could change impression volume, click-through rate and conversion paths.

It also means advertisers need to think about how their ads, product data and landing pages answer user questions, not just how they match a keyword.

What advertisers should be paying attention to

Advertisers should monitor search query behaviour, click-through rate and impression trends as AI Search adoption grows.

Ad assets and landing pages should answer user questions clearly. Product data, commercial messaging and feed accuracy should also be prioritised, especially for retail, e-commerce and product-led advertisers.

AI Search visibility should be treated as part of paid search planning, not as a separate experiment.

Meta Is Becoming A Larger Performance Platform

Business Impact

Meta’s continued growth shows that paid social is playing a bigger role in full-funnel performance, not just awareness or engagement.

This is particularly important for advertisers that still treat Meta as a supporting channel while relying heavily on Google for conversion activity. Meta’s growth is being driven by automation, creative optimisation and newer surfaces that give advertisers more ways to reach users across the funnel.

The opportunity is greater scale. The challenge is making sure creative strategy, tracking and lead quality measurement are strong enough to support that scale.

Meta is projected to overtake Google in global ad revenue

What happened

In May 2026, Emarketer forecasts reported by The Next Web projected that Meta could overtake Google as the world’s largest digital advertising business in 2026.

Meta was forecast to reach $243.46 billion in global net ad revenue, compared with Google’s projected $239.54 billion. The growth was linked to Advantage+ automation and newer ad surfaces, including WhatsApp and Threads.

Why this matters

This reinforces Meta’s position as a major performance platform, not just a social awareness channel.

The growth is being driven heavily by automation, AI-led campaign setup, creative optimisation and new surfaces that expand where Meta can serve ads.

For advertisers, this means Meta should not be treated only as a brand or engagement platform. In many accounts, it may now have a more direct role in acquisition, retargeting and lower-funnel performance.

What advertisers should be paying attention to

Advertisers should review whether Meta is being used properly across prospecting, retargeting and lower-funnel campaigns.

Creative strategy needs more attention, as Meta’s automation relies heavily on creative variety and quality. Tracking quality should also be checked, including Pixel and Conversions API setup.

Meta performance should be assessed using incrementality and lead quality, not only platform-reported ROAS or conversion volume.

Meta Is Reducing Manual Setup Work

Business Impact

Meta is continuing to simplify campaign setup, tracking configuration and creative production through AI-assisted tools.

This can help advertisers move faster, particularly when creating lead forms, testing creative variations or setting up conversion events. However, it also increases the need for quality assurance.

If AI-generated forms, creative outputs or tracking settings are not reviewed carefully, advertisers could end up with weaker lead quality, incorrect event tracking or creative that does not fully match brand expectations.

Meta’s May rollouts point to more AI-assisted setup

What happened

May 2026 Meta Ads coverage highlighted several mid-rollout updates, including AI-generated instant forms from a URL or prompt, new Pixel settings in Events Manager, reported longer purchase audience retention windows, ad-level placement controls and additional Advantage+ creative image generation categories.

Some of these updates appear to be account-dependent and may not be visible everywhere yet.

Why this matters

Meta is reducing manual setup work across lead generation, creative testing, retargeting and tracking configuration.

This is useful for speed, but it increases the need for advertisers to check the quality of AI-generated forms, event setup and creative outputs before campaigns go live.

It also means account audits need to include more than campaign structure. Advertisers should be reviewing platform settings, event quality, audience windows and creative enhancement options regularly.

What advertisers should be paying attention to

Advertisers should check Ads Manager and Events Manager to see which updates are live in each account.

Any AI-generated lead forms should be reviewed before launch to ensure the questions, privacy wording and qualification logic are correct.

Pixel and conversion events should be audited to confirm Meta is receiving clean optimisation signals. Longer audience windows should also be used carefully, especially where purchase intent or product relevance declines over time.

TikTok Is Building A Fuller Advertising Ecosystem

Business Impact

TikTok is continuing to move beyond awareness and engagement into a more complete paid media ecosystem.

For advertisers, this means TikTok may increasingly support more stages of the customer journey, from discovery and creator-led influence through to search behaviour, shopping actions and conversion-focused campaign delivery.

This is especially relevant for brands with strong creative assets, visual products, younger audience segments or content that can be adapted into native-feeling video formats.

TikTok World 2026 introduced full-funnel advertising updates

What happened

TikTok World 2026, announced on 13 May 2026, introduced a broad set of advertising updates focused on AI-powered creative, campaign automation, creator discovery, search visibility, commerce and vertical-specific experiences.

TikTok positioned the updates around turning discovery into measurable business growth.

Why this matters

TikTok is pushing beyond top-of-funnel awareness into a more complete advertising ecosystem.

The platform is trying to connect creator content, search behaviour, shopping actions, AI creative production and campaign optimisation in one environment.

This means advertisers should not only think about TikTok as a place to generate views or engagement. For the right sectors, it may become a stronger test channel for traffic, product discovery, search-led intent and conversion activity.

What advertisers should be paying attention to

Advertisers should treat TikTok as a full-funnel test channel where appropriate, not only an awareness platform.

TikTok creative testing should be used to identify hooks, formats and product angles that can support both traffic and conversion.

TikTok Search and commerce-related placements should be explored where user intent is stronger. Measurement also needs to be set up properly before scaling automated or commerce-led campaigns.

What To Watch Next

• The next few months will be important for advertisers using Google Search, Performance Max, Meta Advantage+ and TikTok automated campaign tools.
• On Google, the key thing to watch is how AI Search changes campaign reporting, query behaviour and user journeys. As ads appear in more conversational and AI-led environments, advertisers will need to understand whether visibility, click-through rate and conversion paths are shifting.
• On Meta, advertisers should watch how quickly AI-assisted setup tools become available across accounts. Lead forms, Pixel settings, creative generation and retargeting controls may reduce setup time, but they still need careful review.
• On TikTok, the main thing to watch is whether new full-funnel tools can turn discovery into measurable performance. Creative quality, search behaviour and conversion tracking will be critical if advertisers want to move beyond awareness-led testing.

What May Tells Us Overall

May’s updates show that paid media is becoming more automated, more conversational and more connected across the full customer journey.

Google is expanding AI-led advertising across Search, Shopping, YouTube, measurement and creative production. Meta is strengthening its position as a major performance platform, while also using AI to simplify setup and creative production. TikTok is building a broader advertising ecosystem that connects creator content, search behaviour, commerce and automation.

The opportunity for advertisers is greater scale, stronger discovery and more ways to reach people before they actively convert.

The risk is reduced visibility and weaker control if campaign inputs, tracking, creative assets and reporting are not properly managed.

That means the role of paid media management is not becoming less important. It is shifting. Advertisers need to spend less time thinking only about manual campaign controls and more time thinking about the quality of the inputs that shape automated delivery.

Strong feeds, useful creative, accurate conversion data, relevant landing pages, clear reporting and regular quality assurance are becoming essential to getting value from automation without giving up strategic control.

Need help?

If you are already investing in Google Ads, Meta Ads or TikTok Ads, now is the time to review how prepared your campaigns are for more automated, AI-led delivery.

The question is no longer only whether your campaigns are live and spending efficiently. It is whether your feeds, assets, tracking, landing pages, creative settings and reporting are strong enough to guide automation in the right direction.
