🤯 The 20-Minute Reverse Sourcing Setup

In our previous blog post, we talked about watching sellers instead of chasing products.

That mindset shift alone puts you ahead of most sellers.

But there’s a fair objection I hear all the time:

“Some storefronts have thousands of ASINs. I don’t have all day to dig.”

That used to be true.

Now it takes about 20 minutes.

Here’s how.

The mistake that wastes hours

When most sellers try to reverse source a storefront, they do the same thing every time.

• They open the storefront

• Scroll endlessly

• Click ASIN after ASIN

• And hope something looks good

That’s how you end up exhausted and empty-handed.

The key is realizing this:

You don’t need all of a seller’s ASINs.

You only need the small percentage that actually matters right now.

That’s where the Signal Filter Method comes in.

Pull everything first (then filter hard)

The Signal Filter Method starts by pulling everything, then ruthlessly narrowing.

Using Keepa Product Finder (KPF), you can pull every ASIN a seller has ever touched, including historical offers.

Then:

• Grab the storefront IDs

• Drop them into KPF

• Include historical data

Now you’re looking at the full picture.

This matters because some sellers:

• quietly test strong products

• sell out

• and move on — even though demand still exists

Those forgotten ASINs often hide the best opportunities.

Where the signal actually shows up

Instead of manually reviewing thousands of ASINs, the Signal Filter Method focuses on price behavior.

Specifically, you’re looking for products where:

• price previously dropped

• sellers exited

• and the buy box is now climbing again

That price recovery usually tells you two things:

• demand never left

• supply temporarily did

That gap is where profit windows open.

Once you apply this filter, the noise disappears.

Tens of thousands of ASINs collapse into a few hundred worth reviewing.

That’s a sourcing session you can actually finish, and repeat weekly.

Why Keepa skill makes or breaks this method

Here’s the honest truth:

Anyone can apply filters.

But very few sellers actually understand what the data is telling them.

That’s why Chris Grant’s Keepa Academy is such a powerful complement to the Signal Filter Method.

It teaches you how to:

• spot real price recovery vs false signals

• avoid traps caused by short-term volatility

• tune filters to your buy cost, rank tolerance, and competition comfort

Instead of guessing, you’re reading the market.

If you’re serious about reverse sourcing and storefront analysis, Keepa Academy can shorten your learning curve by months.

Want the shortcut?

Once you start doing this, you’ll notice something familiar.

The same storefronts keep showing up in your wins.

That’s not random.

It’s the same logic behind our lead lists.

Instead of you pulling storefront data and running the Signal Filter Method yourself, Mercury focuses on:

• products in the top 1.5% sales rank

• strong velocity

• fast-turning opportunities
