Press the Opt out button in the product browsing notice, in Meta Business Suite or Ads Manager, before 28 October. Then open each active ad and confirm the setting is off in its Advantage+ creative and Destination sections. Miss the deadline and you can still switch it off ad by ad. It just takes longer.

Our view: opt out now, then test product browsing deliberately, on a small slice of spend, before Black Friday on 27 November. Here is why, and how.

What Meta is switching on for your existing ads on 28 October

The notice began reaching advertisers around 13 to 14 October. Falia reports a specialist urging advertisers on X to opt out on the evening of the 13th, while PPC Land and Ads Uploader place it on the 14th. The headline is blunt.

Starting October 28, 2026, we'll add product browsing to your existing ads.

Meta's notice to advertisers, as reported by The Keyword

According to the notice, people who tap your ad "may see an experience on Facebook or Instagram with product info and personalized suggestions". It applies to ads that are already live, unless you opt out first.

What product browsing actually does

The feature itself is not new. It has sat among the Advantage+ creative enhancements for a while, and you could already enable it ad by ad. What changes on 28 October is the default for live ads, from off to on.

Meta's Help Center describes a personalised browsing experience, with product details and offers, that opens inside Facebook or Instagram when someone taps the image or video. People are then sent to your website to buy. The key line is that it "may send people to an experience on Facebook and Instagram first before your website".

Your creative stays the same. The first screen after the tap does not.

What Meta has and has not published

As of 15 October, Meta had published no Help Center article, changelog entry or newsroom post about switching this on for existing ads. That finding comes from Ads Uploader and Relevant Audience. The 28 October date comes from advertisers who received the notice. We have seen nothing official since, so treat the notice in your own account as the source of truth.

Meta's documentation has an odd gap too. The Advantage+ creative page lists four enhancements that "may be turned on by default": product tags, reveal details over time, spotlights and summaries. Product browsing is not among them, so the public docs still present it as your choice.

Nor is this the first time. Meta flipped the Dynamic Media default for Advantage+ catalogue ads between 1 September and 20 October 2025. Expect more of the same.

Check your own notice

Meta has not documented this change publicly. Search your Business Suite and Ads Manager notifications for the product browsing notice before acting, and screenshot it for your records.

How to opt out before 28 October

There are two routes. One is fast but expires. The other is slow but permanent.

The notice button and its unclear scope

Find the product browsing notice in Meta Business Suite or Ads Manager notifications. It ends with a single blue Opt out button. Several sources report that the button stops working after 28 October.

Ads Uploader says the link opens Business Suite with a product browsing auto-upgrade opt-out built into the address, and describes it as covering the whole business portfolio. Adrise Lab says it covers the ad account's existing ads. PPC Land and Falia both note that the notice never says which. Meta has confirmed neither reading.

Assume the narrowest scope. If you manage several ad accounts, look for the notice in each one and press the button wherever it appears.

Turning it off ad by ad

This route works at any time, including after the deadline. In Ads Manager:

  1. Open the ad and go to the Advantage+ creative section.
  2. Turn off "Add product browsing". In some accounts it appears under "Personalized destinations" as "Product browsing", so labels vary.
  3. Check the Destination section too, because the notice names both places.
  4. Open Advanced preview. Meta says some enhancements can only be turned off there.

There is no bulk switch. Enhancements live inside each ad's creative, and Meta has not announced an account-level option. For large accounts, Ads Uploader suggests launching new ads with enhancements already off, or using an AI agent connected to Meta's Ads MCP for existing ones. That advice comes from a tool vendor with a commercial interest, so weigh it accordingly.

Checking again after the deadline

Plan a second pass on 29 or 30 October. Spot-check a sample of active ads and look hard at anything new or duplicated. Practitioners report that enhancement settings can switch back on when you copy an ad. That is not Meta documentation, but it costs minutes to check, and duplicating winners is exactly what teams do in the run-up to peak.

Add it to your launch checklist

Until Meta says otherwise, add "product browsing off (Advantage+ creative, Destination, Advanced preview)" to the checklist for every new or duplicated ad.

Why we would opt out first and test second

Opting out costs nothing. You can switch product browsing on for any ad later. Leaving it on means testing a new post-click experience with live peak-season spend, no control group and muddied data, at the point in the year when you can least afford any of that.

Common Thread puts the practical risk well. Between the switch-on and whenever you get round to opting out, spend runs through an experience you did not choose, during the Black Friday ramp-up.

The 3% claim in context

The notice says that, on average, businesses saw 3% more conversions with in-app product browsing than with campaigns that did not use it. PPC Land reports the experiment ran from 6 to 21 August 2026 across about 117,700 advertisers.

Sounds persuasive, until you ask the obvious questions. Which conversion event? Counted where? At what cost per result? Meta has not said. It is Meta's own experiment on its own product, with no independent check. And as Storehero points out, conversions are not profit. Three per cent more purchases at a lower order value can leave you worse off. Treat the figure as a claim worth testing, not a reason to leave the default on.

How to test product browsing before Black Friday

If it might help your account, find out on your terms.

Setting up two comparable arms

Pick a proven catalogue ad, ideally one with steady volume. Then either:

  • use Meta's A/B test tool with product browsing as the only difference, or
  • duplicate the ad into a separate campaign with the same budget, audience and placements, product browsing on in one arm and off in the other.

If you duplicate, check that the control arm really has it off, for the reason given above. Let both arms clear the learning phase before you read anything into the results.

Be honest about the window. There are only a few weeks between 28 October and 27 November, and pre-peak behaviour is not peak behaviour. A test this short can show whether product browsing is clearly harmful or clearly helpful. It probably cannot settle a close call. If the result is marginal, keep it off for Black Friday and retest in January.

Judging it on margin, not Meta's conversions

Do not judge the test on Meta's reported conversions. The feature changes where Meta's tracking starts, so its numbers are the least neutral measure you have.

We judge tests like this on store data: Shopify or WooCommerce orders matched back to each arm by UTM or campaign. We look at revenue, average order value and contribution margin relative to spend. The store is the system that records whether you actually made money. If you want a second pair of hands on the setup, this is the kind of work our paid social and analytics support team runs every week.

What it can do to your tracking on Shopify and WooCommerce

Adrise Lab makes the key point. The creative does not change, but the first screen after the tap does, and that screen is where your pixel, GA4, consent banner and landing page view usually start counting.

Before you test, confirm the basics on your own site:

  • Meta pixel and Conversions API. Check that browser and server events are deduplicated, so a purchase following an in-app session is neither counted twice nor missed. On Shopify, this is a good moment to finish moving tracking pixels to Web Pixels on Shopify if you have not already.
  • UTMs. Click through from a test ad with product browsing on and check that your campaign parameters arrive intact. We have not seen Meta document this either way, so test it yourself.
  • GA4. If browser tracking already loses signal for you, server-side GA4 conversion tracking gives you a steadier baseline to compare against.
  • Consent. People who arrive after an in-app browse still meet your banner, so make sure it is configured correctly. If you sell to UK customers, review what a UK cookie banner now needs to cover.

Why sessions and conversion rate will look different

With product browsing on, some people will look at products inside Meta's app and never reach your site. Palai Media warns that this cuts direct post-click traffic and blends performance data, so you cannot tell how much of a sale came from your creative and how much from Meta's in-app catalogue. That is an informed concern, not a measured result, but plan for it.

Expect fewer sessions per ad click and a landing page conversion rate that moves for reasons unrelated to your site. Tell stakeholders before the dashboards change, not after.

Who might benefit and who should leave it off

Adrise Lab suggests testing on accounts with a clean catalogue and a broad range, and opting out where the landing page carries the sale. Common Thread makes a similar call: keep it off where the landing page conversion experience is central.

From a build perspective, ask what lives on your product pages that Meta's screen cannot reproduce. Bundles, product configurators, subscription options, upsell flows and product detail pages you have tuned over months are all lost when the first screen is Meta's. If those drive your margin, leave product browsing off. If you sell a wide catalogue of simple products and your pages do little beyond showing the item and an Add to basket button, it is a reasonable candidate for a test.

What we still do not know

Several basics remain unanswered:

  • whether ads created after 28 October will have product browsing on by default
  • which placements and formats are affected
  • whether you need a product catalogue for it to appear
  • whether the opt-out button covers one ad account or the whole portfolio
  • what the in-app screen actually looks like, since Meta has not published a screenshot

Until Meta documents these, check new ads by hand and tie your judgement to store data rather than platform reporting. If you want someone to check your tracking and landing pages before peak trading, book a free website audit and we will reply within four hours during UK business hours.
