Infinite Lookback : Why a 7-Day Cookie Is Killing Your Ecommerce Growth

When you look at your marketing attribution dashboard, do you feel a surge of confidence or a chill of doubt?

If you rely on the industry-standard 7-day cookie for tracking, that doubt is justified. You might be celebrating short-term wins while the true drivers of your growth, the clicks that started the entire customer journey, fly completely under the radar.

At Wicked Reports we built our solution around infinite lookback for exactly this reason.

How Huha Scaled from $1M Toward $30M by Escaping the 8-Figure Attribution Trap

Most brands do not stall at eight figures because they run out of demand. They stall because they can no longer tell which marketing is actually driving growth. At $1M in revenue you can feel your way forward. At scale, feeling your way forward is how you set fire to a budget. This is the story of how the agency Magic vs Machine scaled Huha from roughly $1M to $23M and counting, on track toward $30M, bootstrapped, by fixing the one thing that breaks at scale: knowing what actually works.

LAST-CLICK ATTRIBUTION FOR ECOMMERCE  : WHEN TO USE IT AND WHEN IT LIES TO YOU

Last-click attribution is the most widely used model in ecommerce, and also the most widely misunderstood. It is not useless, and it is not evil. It is a narrow lens that is genuinely useful for some questions and dangerously misleading for others. The problem is that most platforms default to it, so most marketers end up making broad budget decisions through a lens built for a much smaller job. Here is what last-click actually does, when it is fine to rely on, and when it will quietly lead you to spend in the wrong places.

If you're running paid on both Meta and Google — or deciding where to put your next budget increase — you've probably noticed the two platforms behave nothing alike.

FIRST-CLICK ATTRIBUTION: WHEN THE FIRST TOUCH IS THE ONE THAT MATTERS

Most attribution debates obsess over the last click — who closed the sale. But for any brand that lives or dies on acquiring new customers from cold traffic, there's a more important question the last click can't answer - what actually made this person aware of you in the first place? That's what first-click attribution is for. Here's when it's the right lens, when it isn't and why it's the natural counterpart to last-click in a complete measurement picture.

PINTEREST ATTRIBUTION : HOW TO TRACK THE REAL ROI OF A SLOW-BURN CHANNEL

Pinterest is one of the most misjudged channels in ecommerce advertising, and the reason is timing. Pinterest users are often in the research and inspiration phase, saving ideas and planning purchases they will make weeks or months later. That makes Pinterest a powerful demand-creation channel, and it also makes it one of the easiest channels to undervalue, because the sale it started often closes much later through another touch. If you judge Pinterest on last-click or a short platform window, you will almost certainly underrate it. Here is how to track the real ROI of your Pinterest ads.

Meta Is Pushing Advantage+ Campaigns Relentlessly. Here's What 55,661 Campaigns Reveal.

The promise of Andromeda's AI brain sorting through a billion users to find your customers on auto-pilot sounds quite enticing. But I could not help wondering: is this actually a good thing for brands?

I ask because I have spent 10 years tracking Meta campaign performance against actual orders, and four things have stayed true the entire time.

Meta overstates its ability to drive immediate bottom-of-funnel sales.
Meta understates its ability to drive top-of-funnel cold traffic that leads to new customers.
Meta shows a lot more ROAS when you widen the attribution time window.
Meta's Conversions API is heavily optimized for immediate sales on the default setup.

With Meta now all but forcing advertisers into Advantage+, or switching it on behind the scenes if you do not read the fine print, it is time to use actual data, not opinion, to work out how advertisers should really use Advantage+, and when to stick to their manual guns instead.

So I had the fearless Wicked DB team pull the data on 55,661 Meta campaigns, comparing January through May 2024 against 2025, to finally get to the bottom of a few things. Let's dive in.

iOS 26 and Tracking Parameters: What Performance Marketers Need to Know

The release of iOS 26 has raised alarm bells across the digital marketing community. For performance marketers, agencies, and data analysts, the fear is always the same: "Will my tracking break, and will I lose visibility into what's really driving results?"

Meta Advantage+ vs Manual: What 55,661 Campaigns Reveal About nCAC

The promise of Meta's Andromeda AI brain sorting through a billion users to find your customers on auto-pilot sounds enticing. But is it actually good for brands? I have spent 10 years tracking Meta campaign performance against actual orders, and four things have stayed true the entire time:

Meta overstates its ability to drive immediate bottom-of-funnel sales.
Meta understates its ability to drive top-of-funnel cold traffic that leads to new customers.
Meta shows a lot more ROAS when you widen the attribution window.
Meta's Conversion API is heavily optimized for immediate sales on the default setup.

With Meta now pushing advertisers hard toward Advantage+, and switching it on behind the scenes if you do not read the fine print, it is time to settle this with actual data instead of opinion. So I had the Wicked DB team pull 55,661 Meta campaigns and compare January through May 2024 against the same window in 2025. Here is what the data shows.

Calculate Your True New Customer Acquisition Cost (nCAC)

If you run paid acquisition for a brand or an agency, you already know the goal: bring in new customers profitably. The problem is that the number most people use to measure that, the cost per acquisition their ad platform reports, is quietly lying to them. It blends new customers and repeat buyers into one figure, which makes acquisition look cheaper and easier than it actually is. The metric that tells you the truth is your new customer acquisition cost, or nCAC. Here is what it is, how to calculate it, and how to use it to grow.
