Over the past few weeks, Meta has quietly moved more decisions from advertisers to its AI. If you run Facebook or Instagram ads, some of your ads may no longer look, behave or measure exactly the way you set them up. None of these changes is dramatic on its own. Together, they're a good reason to check your account this week.

What's changed (as of 3 November 2026)

• More AI-made creative. In October, Meta made its tool for turning static images into video generally available and expanded its AI creative features. These can change images, add motion and music, or rework your text.
• Product browsing switched on for existing ads. From 28 October, Meta began adding product browsing to existing ads unless advertisers opted out, so some clicks may open an in-app shopping experience instead of your page.
• Fewer placement controls. More campaign types have lost the option to exclude specific placements, so your ads can appear in more places by default.
• A Pixel measurement change on 12 November. A setting that measures conversions on shoppers' own devices is due to switch on by default.
• New ad terms on hold. Meta planned updated advertiser terms for 30 October, then 20 November, and has since said it won't make the changes without consulting industry groups. For now, the existing terms still apply.

Why it matters

The ad your customer sees, the page they land on and the way a conversion is counted can now all differ from what you originally set up. Meta's AI optimises for the results it can measure. It doesn't know your brand guidelines, your margins or the claims you're allowed to make. That part is still your job.

Five checks to make this week

1. Review creative enhancements on every live ad. In Ads Manager, open each ad's creative settings and see what's switched on. Keep what genuinely helps, and turn off anything that changes your logo, product images, prices or claims.
2. Preview before you publish. Check the preview for every placement, especially any video versions generated from your images.
3. Decide on product browsing. If your landing page does the selling (a lead form, a WhatsApp chat, a booking page), check whether product browsing is on and opt out where it doesn't fit.
4. Get ready for 12 November. Write down your conversion numbers for the week before, then compare them after the Pixel change. If numbers jump or drop, find out why before you move budget. Make sure your privacy policy and cookie consent cover how you measure.
5. Keep a simple change log. Note what Meta changes and what you change, with dates. When results move, you'll know why.

The bigger lesson

This is the AI + marketer question in practice. Meta's tools can save time and find results you'd miss. But someone still has to decide what's acceptable for the brand, what counts as a conversion and when to switch something off. AI does the volume. You do the decisions.

If your team runs Meta ads and isn't sure what's switched on in your account, a monthly review is exactly what our consulting covers.
