Five years ago, a good Meta campaign was mostly a good audience: carefully stacked interests, lookalikes of the best customers, and ad sets split finely enough to control where the money went. That way of working has been retired, gradually and then quickly. Meta's delivery system now picks the audience itself, and the lever an agency still controls is what it gives the system to work with.
This explains how the system works, from Meta's engineering posts, its business guidance and its July 2026 results, and what that means for how campaigns are set up.
How an ad reaches someone
When someone opens Facebook or Instagram, Meta has tens of millions of ads that could be shown. The first stage, a retrieval system called Andromeda that Meta described in December 2024, narrows those to a few thousand candidates. Ranking models then predict how likely each candidate is to lead to the result the advertiser asked for, and an auction decides which ad is shown.
Both stages keep getting larger models. In July 2026 Meta described the Meta Generative Recommender, which uses large language models to reason about what an ad contains and what a person wants, and said it had put its first generative model into the retrieval stage. Together with other model upgrades, Meta said this had increased ad clicks on Facebook by 8.3 percent and conversions by 15.7 percent. The practical point, though Meta has not put it this way, is that a system that reads the creative itself (what is in the picture, what the words say, who it seems to be for) relies far less on an advertiser telling it.
Why creative is now the targeting
If the system reads each ad and finds the people it suits, then each distinct ad is, in effect, a different audience. Meta says so directly: its guidance calls creative diversification the best lever for finding the most relevant audiences, ahead of narrow targeting.
Diversification is not the same as producing more variations. Meta distinguishes between diversification, which means genuinely different assets for different kinds of people, and iteration, which means small changes to one idea. Ten versions of one video with different headlines look like one ad to the system. A product demonstration, a customer testimonial, a founder talking to camera and a price-led still look like four.
- Brief concepts for different buyers and different reasons to buy, not variations of one concept.
- Mix formats: video and stills, vertical and square, polished and filmed on a phone.
- Meta sets no fixed number of ads per ad set. It recommends a broad portfolio instead.
- Keep the words inside the safe zones, since each asset may run in feeds, Stories and Reels.
Advantage+ campaigns
Advantage+ is Meta's name for its automated campaign settings, and in 2026 it is one structure for sales, app and lead campaigns. A campaign counts as fully Advantage+ only when three settings are on: the budget is set at campaign level, the audience is Advantage+ audience, and it runs on all placements with no exclusions. Meta has closed its older automated campaign types to new campaigns through its API.
Advantage+ audience works with suggestions and controls. Suggestions, such as interests or a customer list, are hints the system may go beyond. Controls are hard limits it will respect: minimum age, locations, languages and excluded audiences. For Gulf campaigns that means the things that matter legally and commercially, the country, the language and the age limit for regulated products, are set as controls, and everything else is left to the system.
Placements are moving the same way. Social Media Today reported in August 2026, from notices inside Ads Manager, that Meta is removing the option to exclude placements from ad sets. Meta had not announced a timeline when we checked. Plan creative on the assumption that every ad can appear in every placement.
Simplify the account
Meta's own framework for performance, which it calls Performance 5, puts account simplification first and calls it the foundation for everything else. Fewer campaigns and ad sets give each one more data to learn from. Meta says advertisers who keep under 20 percent of their spend in the learning phase can cut their cost per purchase by up to 68 percent. The rest of the framework is automation, creative diversification, data through the Conversions API, and validating results with proper measurement.
- Merge ad sets that differ only in a small targeting detail.
- Stop splitting budgets by placement or by narrow interest.
- Send conversions through the Conversions API as well as the pixel, so the system learns from the full picture.
- Judge results over a period long enough for the system to learn, not day by day.
Creators and partnership ads
Meta has been pushing brands toward running ads through creators' accounts. It says partnership ads average 19 percent lower cost per acquisition and 13 percent higher click-through rates. Its Creator Marketplace opened globally in January 2026, and on 15 September 2026, the day Meta One launched, it rolled out a Creator Marketing Hub that brings creator discovery and partnership ads together, with partnership ads from Instagram Live due to become generally available on 29 September. Partnership ads carry a Paid partnership label.
AI tools, and the Arabic question
More than nine million small businesses used at least one of Meta's AI creative tools in the second quarter of 2026, according to Meta. At Cannes in June 2026 it showed an end-to-end creative tool with a brand memory, in testing, and video voiceover translation that includes Arabic. Translated voiceover can be a quick way to test an idea in a second language, but it is not a substitute for creative made in Arabic for an Arabic audience. Review anything generated before it runs, and keep the client's approval on record.
For agencies building their own tools, Meta also opened an ads MCP server and command line tool in beta in April 2026, with controls added in July so a business admin can decide what AI agents are allowed to do in the account.
Gulf billing, currency and VAT
- Ads for advertisers outside the United States and Canada are sold by Meta Platforms Ireland Limited, which is the entity on the invoice for UAE and Saudi accounts.
- Ad accounts can be set up in dirhams, riyals, Qatari riyals or Bahraini dinars. Kuwaiti dinars and Omani riyals are not on Meta's list of supported currencies.
- Meta's help pages for the UAE and Saudi Arabia say VAT is added to ad charges when the account has no tax registration number on file. Add the client's TRN or VAT number to the ad account's business information so the invoice is right from the first charge.
- Since 1 July 2026, Meta charges location fees on ads shown to people in some European countries, including 2 percent for the UK, 3 percent for France, Italy and Spain, and 5 percent for Austria and Turkey, with VAT on top. A Gulf tourism or property client advertising in Europe will see it on the invoice.
- Ads about social issues, elections or politics need authorisation and a Paid for by disclaimer in Saudi Arabia, Qatar and the UAE, which Meta has enforced since September 2022.
What this changes for an agency
The skill has moved from building audiences to building inputs: a simple account structure, clean conversion data and a steady supply of genuinely different creative. That changes what an agency should be staffed and paid for. Media buying hours shrink; creative strategy, production and measurement grow. Retainers priced on the old model should be looked at again.
The ad mockup generator on this site shows one piece of creative in all six Meta placements, with each app's text cuts and safe zones, which is exactly the check that matters when every ad can appear anywhere.
