How to tell if a company advertising on Facebook is a scam: 7 checks that take 10 minutes

Start with the odds, not the ad

This is now the single most expensive way ordinary people get scammed. FTC data shows that in 2025 nearly a third of everyone who reported losing money to a scam said it started on social media, with reported losses hitting $2.1 billion. Investment pitches were the worst of it — about $1.1 billion — followed by fake stores and romance scams that pivot to 'opportunities.'

None of that means every Facebook advertiser is a crook. It means the base rate is high enough that 'it was in my feed, so it's probably legit' is exactly backwards. Treat an unfamiliar advertiser as unproven until it clears the checks below — the same way you'd treat a stranger knocking on your door with a deal.

Look the advertiser up in Meta's own Ad Library

Meta runs a free, public database of every ad currently running across Facebook and Instagram: facebook.com/ads/library. Search the company name and read the history like a background check. The tells: a Page created only days or weeks ago, a Page that has been renamed several times (the 'Page transparency' section lists past names — legitimate brands rarely churn identities), and an account blasting out dozens of near-identical ads at once.

Known scam operations show this pattern plainly. Investigators documented one advertiser running the same fake-spending-card ad more than 40 times, and a fake 'senior benefits' operation pushing 250-plus ads to over a million people. A page that's a week old running 40 versions of one pitch is a loud signal.

One caveat, so you calibrate correctly: Meta has been criticized for making flagged scam ads harder to find and pulling them after the fact, so a clean-looking history is not proof of safety. Use the Library to disqualify, not to fully clear. A thin or freshly created advertiser is a stop sign; a long history just means you keep checking.

Check how old the website is — and who owns it

Pull the store's domain (the part after https:// and before the first slash) and run it through any free WHOIS or domain-age lookup. A site registered days or weeks ago that claims to be an established brand is one of the most reliable red flags there is. Fraudulent stores are disposable by design; they're often registered right before an ad blitz and abandoned after the chargebacks land.

Watch two variations. Typosquatting: a domain that's one letter or hyphen off a real brand (nike-outlet-store.shop, amaz0n-deals.com). And repurposed domains: scammers buy expired domains that once belonged to a real business to inherit a bit of age and trust. If the name is almost-but-not-quite a company you know, slow down.

Then look at who stands behind it. Private/anonymous registration combined with no physical address, no phone number, and only a web form or a free Gmail address means they don't want to be found. A real company that wants your repeat business tells you where it is.

Follow the payment: how they want to be paid tells you almost everything

This is the fastest tell of all. Gift cards, cryptocurrency, wire transfers, and 'friends and family' sends on Zelle, Venmo or Cash App all have one thing in common: once the money leaves, you cannot claw it back. The FTC is blunt about it — only scammers demand payment in cryptocurrency up front, and no legitimate seller asks you to pay with gift-card codes. If those are the options, you already have your answer.

A credit card is your friend here, because it gives you chargeback rights and a dispute process if the goods never arrive. If a checkout quietly steers you off the site to an unbranded payment portal, or the only methods offered are the irreversible ones above, close the tab. A real store wants to make paying easy and safe; a scam wants to make refunds impossible.

Reverse-image-search the product and the 'founder'

Drag the product photo into Google Images or TinEye. If the identical image turns up on AliExpress and a dozen other 'brands' under different names and prices, you're looking at a generic dropship — at best you overpay and wait a month; at worst nothing ships. Do the same with the founder's headshot and any 'as seen in' badges; stolen and AI-generated faces are cheap.

Be especially ruthless with celebrity and doctor endorsements. AI deepfakes now put famous faces behind no-name products. If a celebrity or physician is pushing an unknown product in a Facebook ad, assume the endorsement is fabricated until you find it on that person's own verified channel. These campaigns are not fringe: a small set of scam advertisers racked up hundreds of millions of impressions on Meta, and the majority landed on users over 65.

Read the reviews for the burst pattern, not the star rating

Stop counting stars and start reading timestamps. Manufactured reviews arrive in a burst — a wall of five-star ratings all posted within the same few days, all vague ('great product, fast shipping, love it'), all oddly similar in phrasing. AI writes these by the thousand now. Genuine reviews trickle in over months and describe specific, mixed experiences.

Since October 2024, the FTC's fake-reviews rule bans buying, selling or generating fake reviews — including AI-written ones — with civil penalties up to about $51,744 per violation. That tells you two things: the practice is widespread enough to warrant a federal rule, and honest companies don't touch it. Then go off the seller's own site: check the BBB, an independent review platform, and a plain Google or Reddit search for '[company name] scam.' Read the one- and two-star reviews specifically — real complaints name real failures.

Find the refund policy and a real human — before you pay

A real store states plainly how to return an item: to what address, within how many days, who pays return shipping, and how to reach support. A scam is vague or silent on every one of those. If the refund policy is a paragraph of feel-good copy with no address and no timeframe, treat it as nonexistent — because functionally it is.

Test the support channel before you buy, not after. Send a simple pre-sale question — 'What's your return window and where do I ship returns?' Silence, a bounce, or a nonsense reply is your answer. It's much easier to walk away from a $60 gadget now than to chase a refund from a company that has already vanished.

The ten-minute verdict: if the Page is new, the ads are new, the domain is weeks old, the only payment options are irreversible, the reviews arrived in a burst, and no human answers a basic question — that's not a business having a rough launch. That's a countdown. Close the tab and keep your card in your pocket.
