Why are some supplements everywhere in ads?

Because the people running those ads are usually paid only when you buy, and a large share of the price often goes to them. Offers that convert well attract more affiliates, and each affiliate runs its own ads. ClickBank's "gravity" score tracks that crowd. A supplement that is everywhere in your feed has many affiliates behind it, which says nothing about whether the formula is any good.

What is ClickBank gravity?

Gravity is a number ClickBank calculates for each offer in its marketplace. ClickBank's help center says it reflects how many affiliates have earned a commission by promoting the offer in the past 90 days, with more recent activity counting more. ClickBank's own blog describes the same score as a rolling 12-week window. Either way, it is roughly the last three months.

Two details matter. First, gravity counts affiliates who made at least one sale, not the number of sales or the revenue. ClickBank treats rank, which follows sales volume, as a separate signal. Second, ClickBank itself notes that a higher gravity means more affiliates are successfully promoting an offer, but also possibly more competition. It says nothing about what the product does for a buyer.

How are affiliates paid?

An affiliate promotes an offer with a tracking link, and earns a commission only when a customer buys through it. The seller sets the commission, either as a percentage of the sale (revenue share) or as a flat fee per action (CPA). If the sale includes a recurring part, the commission on that part can be different.

The amounts are not small. ClickBank's seller guidance says affiliates are more likely to promote products when the commission they are offered is between 50 and 75 percent. It also says a flat CPA fee lets affiliates know exactly what they will earn per conversion without worrying about refunds or chargebacks, which matters most to affiliates running large paid campaigns. In the same guide, ClickBank tells sellers that giving affiliates ready-made branding and marketing content is a good way to attract them.

Put those together and the pattern behind the ads is easy to see. A seller who pays a large share, supplies ready-made creative and wants volume will get many affiliates. Many affiliates mean many ads, often with the same claims, because they start from the same material.

What do gravity numbers look like in our list?

On September 28, 2026, we saved a list of 447 health offers from the ClickBank marketplace with their gravity scores. The median offer scored 1.7. Only 29 offers scored 20 or more, and the highest was 100.4. Most health offers have few affiliates behind them. A small group has a lot.

Here is how some of the offers we have reviewed sit on that scale, with the verdict we gave them after checking the label, the price, the refund terms and the seller:

Offer	Gravity (Sept. 28, 2026)	Our verdict
ProstaVive	49	Worth a look
ProDentim	45.9	Worth a look
Joint Genesis	42	Worth a look
Audifort	31.5	Doesn't add up
Prostadine	26.6	Doesn't add up
Liv Pure	20.3	Worth a look
KeySlim Drops	2	Doesn't add up
Leptozan	1	Worth a look
VivaSlim	0.7	Worth a look
MannaFlux	0.3	Doesn't add up

The first group is the one you meet in feeds and search ads. The second group has so few affiliates that you are unlikely to see them advertised at all. Gravity moves over time, so treat these numbers as one day's snapshot.

Does high gravity mean a better supplement?

Not in our data. Of the reviewed offers with gravity of 20 or more in that list, 21 in all, none earned our top verdict, "Holds up," and none scored above 6.3 out of 10. Seven of them landed in "Doesn't add up." Across all 518 of our reviews, only three reached "Holds up," and all three are ClickBank offers with a gravity of 0.7 or less.

That is not a rule. Our reviews cover a limited set of offers, and a low gravity can simply mean a new or niche product. The point is narrower: popularity among affiliates is a measure of selling power. It is not a quality check, so do not use it as one. Our review method scores the evidence, price, refund and transparency instead.

Why do the ads for one supplement look so alike?

Three reasons stack up. Affiliates start from the seller's own pages and creative. They also follow what already converts, so the same hooks, such as a "secret" ingredient or a hidden cause, get repeated. And the listings are written for the people who sell, not for you. In the saved list, one dental offer is titled "The Biggest Monster In The Dental Niche" and another "Made to Convert." Those are pitches to affiliates, and they show who the first audience is.

When you see five ads for one product, you are often seeing five affiliates, not five independent opinions.

What does the FTC require of affiliates?

The FTC's Endorsement Guides Q&A says an affiliate should disclose the relationship clearly and conspicuously, so readers can decide how much weight to give the endorsement. It adds that the closer the disclosure is to the recommendation, the better. It also warns that "affiliate link" alone may not be understood by consumers, and that a "buy now" button is not an adequate disclosure.

The FTC's health products guidance adds that claims about the health benefits or safety of dietary supplements need competent and reliable scientific evidence, and that anyone who participates directly in marketing, or has authority over it, has an obligation to check that claims are truthful and supported. In plain terms, an affiliate cannot treat a seller's claim as someone else's problem.

We follow the same standard. Many links on DoseAudit are affiliate links, we say so on our affiliate disclosure page, and a commission never changes a score. Offers that fail our checks are published with a negative verdict.

How should you read a supplement ad?

1. Look for the disclosure. If the page earns a commission and says nothing, treat it as an ad.
2. Find the seller and the label. A named company, a full Supplement Facts panel and a physical address are good signs. Many offers have none.
3. Compare doses with research. Our weight management reviews and other categories show how that comparison looks.
4. Check the refund before you pay. Our ClickBank refund guide explains who handles it and how to ask.
5. Ignore popularity. A million impressions are not evidence. A reviewed label and a checkable study are.
6. Ask a professional. A doctor or pharmacist can tell you about interactions with your medicines.

FAQ

What is a good gravity score on ClickBank?

There is no good or bad. ClickBank describes higher gravity as more affiliates earning commissions, with possibly more competition, and lower gravity as a less crowded market or a niche offer. In our list of 447 health offers the median was 1.7 and the maximum was 100.4.

Does high gravity mean more sales?

Not directly. Gravity counts affiliates who earned a commission recently, with recent activity weighted more. It does not report the number of sales or the revenue; ClickBank's rank is a separate figure.

Why am I seeing the same supplement everywhere?

Usually because many affiliates are paid to promote it, and because ad platforms show you more of what you have clicked. A big affiliate crowd makes a product look established, but the product is still just an offer you can check against its label and refund terms.

How much commission do ClickBank affiliates earn?

The seller sets it, as a percentage or a flat fee. ClickBank's own guidance to sellers says rates between 50 and 75 percent are more likely to attract affiliates. The exact rate is shown to affiliates in the marketplace, not to buyers.
