Run ads with Mist

Mist can write ads for your products, check them for claims Meta and Google reject, make images at the right sizes, and create the campaign in your own ad account. Every campaign Mist creates starts paused. Nothing spends money until you switch it on in Meta Ads Manager or Google Ads. Your ad account pays Meta or Google directly. Fluid never handles your ad spend.

​

Before you start

You need these before Mist can launch anything:

• For Facebook and Instagram:
  • A Meta business portfolio (Business Manager) that owns at least one product catalog. Fluid’s Meta connection uses the catalog for your products, and it won’t connect without one.
  • A Facebook Page the ads run as. To run on Instagram too, link an Instagram account to that Page in Meta.
  • An active Meta ad account with a payment method, in the same business portfolio.
  • A person who is an admin of that business portfolio to approve the connection.
• For Google:
  • A Google account that can reach a Google Merchant Center account and the Google Ads account the ads run in. One Google sign-in connects both.
  • A Google Ads account that is enabled and has billing set up. A manager account can’t run ads, so choose the account under it.
• In Fluid: an admin with the Company settings permission, to connect accounts and launch campaigns. Making images needs the Media permission too.

A test store can’t connect Meta or Google.

​

Connect Meta

1. In Mist, type:

   Connect my Meta ad account.

2. Mist opens Meta’s login in your browser. Log in with the Facebook account that manages your business.
3. When Meta asks, keep every permission switched on, including ads access. Share your business, catalog, ad account, Facebook Page and Instagram account with Fluid.
4. Go back to Mist and say you’re done. Mist checks the connection.

You can also connect from the admin: open Settings › Sales Channels › Meta Commerce and click Connect Meta Business. If Sales Channels isn’t in your Settings sidebar, connect from Mist instead.

​

Choose your Meta ad account

Once Meta is connected, Mist lists the ad accounts and Pages Meta shared with Fluid. Tell Mist which ad account and Page the ads run as, and whether to run them on the Page’s Instagram account too. Mist asks you to approve the choice before it saves it. Only an active ad account can run ads. If the account you want is missing, Meta didn’t share it with Fluid. Connect again and share it when Meta asks. In the admin, the Ad account card on the Meta Commerce page shows the saved choice. Use Change to pick another one, or Clear to remove it.

​

Connect Google

1. In Mist, type:

   Connect Google so I can run Google ads.

2. Mist opens Google’s sign-in in your browser. Sign in with the Google account that manages your Merchant Center and Google Ads.
3. Allow every permission Google asks for, including Google Ads access.
4. Go back to Mist and say you’re done.

Mist then lists the Google Ads accounts your sign-in can reach. Choose the one the ads run in. Manager accounts and accounts that aren’t enabled can’t be chosen. You can also connect from the admin: open Settings › Sales Channels › Google Shopping and click Connect Merchant Center. Then pick the account on the Google Ads account card.

​

Launch a campaign

Tell Mist what you want to advertise, who it’s for, and your budget:

Run a Facebook and Instagram campaign for the Daily Greens powder in the US, $25 a day, sending people to the product page.

Mist then works through these steps with you:

1. Brief. Mist asks about anything it needs, such as the audience, the offer, or the landing page.
2. Copy. Mist writes the headlines and text for each ad.
3. Claims check. Fluid checks every line before anything goes to Meta or Google. Mist rewrites any line that makes a claim Meta or Google reject, such as a health claim or a guaranteed result. If a line still fails, Fluid refuses to launch it.
4. Images. Mist uses your product images where they fit each placement’s shape. If none fits, Mist offers to make new ones (see Images).
5. Approval. Mist shows you the ads, images, budget and countries on an approval card. Nothing launches until you approve.
6. Launch. Mist creates the campaign in your ad account, paused, and gives you the link to it.

What Mist creates:

​

Switch the campaign on

Mist never switches a campaign on. Open it in Meta Ads Manager or Google Ads, check the ads, the budget and the audience, and switch it on there. Meta and Google may review the ads before they run.

​

Images

Each placement has its own shape: When your product has no image that fits a shape, Mist can make up to four new ones from your product’s photos and details. Mist asks before it makes any. Images use your company’s AI credits, and they show as Image generation on AI Spend. Mist saves each image to your Media library, tagged ads, so you can find and reuse it.

​

Check how a campaign is doing

Ask Mist:

How is the Daily Greens campaign doing this week?

Mist reads the campaign live from Meta or Google and tells you whether it’s paused or running, what it has spent, and how many people saw and clicked the ads. It also gives you the click-through rate and cost per click. Pick any date range. Without one, Mist reports from the day the campaign launched to today. Mist only reads results. To change a running campaign, edit it in Meta Ads Manager or Google Ads.

​

Troubleshooting

• Mist says Meta or Google didn’t grant ads access. Connect again, and keep ads access switched on when Meta or Google asks. If you keep getting this message, contact Fluid support.
• Your ad account or Page isn’t in the list. It wasn’t shared with Fluid. Connect again and share it, or ask the business admin to give your Facebook or Google account access to it.
• The ad account is disabled or closed. Meta or Google stopped it, often over billing. Fix it in Meta or Google, or choose another account.
• You chose a Google manager account. Choose the Google Ads account under it, where the ads run.
• Mist says the connection expired. Connect Meta or Google again.
• Mist says a launch is still being created. An earlier launch didn’t finish. Check your ad account for the campaign before you ask Mist to launch again, so you don’t end up with two.
• Fluid refused the copy. A line failed the claims check. Ask Mist to rewrite it.
