Your competitor's entire ad account is public. Every creative they're running right now, the copy, the landing page, and the date each one went live. Free, no login.

Most people open it, scroll for ten minutes, screenshot four ads they like, and close the tab. That's not research. Here's how to actually use it -- and one number from an Indian D2C account that should change how you read offers.

## What you get and what you don't

| You get | You don't get |
|---|---|
| Every live ad | Spend |
| Ad copy and headline | Impressions or reach |
| CTA button and landing page | CTR or conversions |
| Platforms it runs on | Audience targeting |
| **The date it started running** | Any "winner" label |

That last one on the left is the whole game. More on it in a second.

## The 5 steps

**1. Find the right page.** Search the brand. Big advertisers run separate pages for regions and sub-brands -- the one with the ads is the real account, not the one with the nicest profile photo.

**2. Filter to India** (or whichever market you sell in). The same brand's India and US creative often share nothing but the logo.

**3. Sort to the oldest ads still running.** Do not start with the newest. Newest shows you what they're guessing at. Oldest-still-running shows you what survived.

**4. Write down the start date for every ad you save.** A screenshot without a date is useless in two weeks. The date is the data.

**5. Open the landing page.** The Ad Library hands you the exact URL. That's where the offer, the price, the form and the funnel actually live. Almost nobody clicks it.

## Why the date matters more than the creative

Nobody keeps paying to run an ad that's losing money.

So an ad that's been live 140 days has survived every optimisation decision in that account since launch. An ad live 3 days has survived nothing. That's your only performance signal, and it's free.

Second signal: count the duplicates. One version of an idea is a test. Eight near-identical copies is a brand putting budget behind it.

## The number most D2C brands get wrong

Here's what happens when you stop looking and start counting.

Foxtale runs **1,954 ads**. Decode every offer they've run and sort by how long each type survives:

| Offer type | Share of their offer ads | Average days live |
|---|---|---|
| Bundle Deals | 46.9% | **55.2** |
| Buy One Get One | 25.8% | **2.5** |
| Buy More, Save More | 13.7% | 4.0 |
| Cash Discount | 1.1% | 95.8 |

BOGO is a quarter of their offer ads and dies in **two and a half days**. Bundles last fifty-five.

Think about how much Indian D2C creative is BOGO. Think about how much of yours is.

Their survivors aren't offer ads at all. The longest-running creative in the set is a plain how-to -- apply, keep for 10 minutes, enjoy glass skin -- which ran **185 days**, got switched off, and was relaunched for another 47.

</div>

Their other long-runners lead with a claim and a number, not a discount.

</div>

Seven days, stated on the frame. No discount anywhere in it.

</div>

Same pattern across all of them: say the result, put a number on it, skip the deal.

## Before you copy that -- check your own category

This is where most blog posts would tell you BOGO is dead. It isn't.

Run the same count on Minimalist, also Indian, also skincare, 976 ads:

| Offer type | Share | Average days live |
|---|---|---|
| Free Gift with Purchase | 52.4% | 30.0 |
| Buy More, Save More | 17.2% | 57.2 |
| Buy One Get One | 15.0% | **54.7** |

Minimalist's BOGO runs **54.7 days**. Foxtale's runs 2.5.

Same country, same category, opposite answer. So the finding isn't "BOGO doesn't work." It's: **run this count on your own competitors, because the answer is different for every account.**

## Do this in 90 minutes

Open a sheet. One competitor. Forty rows -- any fewer and the percentages are noise.

Columns: start date, days live, number of copies, hook type, offer type, landing page offer.

Then one pivot: average days live, grouped by offer type. Put share next to it.

If their biggest offer type is also their longest-lasting, they know what they're doing -- go find a different angle. If it's their shortest, you've found a gap they're paying for and haven't noticed.

## Three quick rules

- **Don't trust a single ad.** One long-runner can just be a forgotten ad in a messy account. The pattern across a set is the signal, not any one creative.
- **Don't benchmark across categories.** Foxtale's worst offer lasts 2.5 days; in UK business lending a 15-day ad is a star performer. Different clocks entirely.
- **Check once, you have a snapshot. Check again in 30 days, you have direction** -- and direction is the more valuable half.

## FAQ

**Is the Facebook Ad Library free?** Yes, and no login needed for most of it. It covers ads across Meta's platforms, not just Facebook.

**Can I see competitor spend?** No -- not for normal commercial ads. Spend ranges and demographics are published only for political and social-issue advertising. Any tool quoting you a D2C competitor's spend is estimating, not reporting.

**How many ads should I look at?** Forty per competitor. Below twenty the percentages mean nothing.

**Can competitors see my ads?** Yes, with start dates, for as long as they run. Run this check on your own account before someone else does.

**Is this legal?** It's a public transparency tool built to be looked at. Copying structures is fine. Copying their actual creative or copy is not.

## When doing it by hand stops working

Foxtale is 1,954 ads. Funding Fred, a UK lender we also pulled, is 6,472. At 30 seconds an ad that's 54 hours.

So nobody reviews them all -- they read three screens, which is a sample of what a brand makes *most* of, not what works.

[Marxx competitor tracking](https://marxx.ai/#competitors) runs this continuously across Meta, Google and keywords -- every creative decoded on arrival, so the offer-vs-lifespan read stays current without anyone scrolling.
