Does Your E-commerce Site Have The Right PPC Structure? Here’s How To Fix It

A classic assumption in e-commerce is: if your PPC isn’t working, you just need better ads.

Better copy, better creatives, bigger budgets – you get it.

But actually, most underperforming e-commerce campaigns don’t have an ad problem; they have a structure problem.

If your account structure is messy, misaligned, or overly automated (we’ve all been there recently), you’re sending bad signals to the system. And then it simply doesn’t matter how good your product photos look or how compelling your copy is.

So, if you’re looking for performance that matches your hard work and creativity, you need the right e-commerce PPC structure. Here’s how to tell if it’s right, and how to fix it if it isn’t.

What “Good Structure” Actually Means

Okay, so what does “better structure” actually mean?

It doesn’t mean building something complex, layered, or overly granular. You’re looking for control and clarity, so you can look at your account and quickly understand what’s happening, and then act on it.

You should be able to direct budget towards the products and categories that you can see are genuinely driving profit, rather than watching spend get absorbed into a blended campaign with no clear priority. You should be confident that different types of search intent are being handled appropriately, with the right products showing up for the right queries, instead of everything competing in the same space.

It also means that your highest-value products are nice and clear. Whether that’s bestsellers, high-margin lines, or strategic ranges, they should be visible, controllable, and scalable without being affected by lower-priority items.

And when something works, you should be able to push it further (increase budget, adjust bids, expand coverage) without unintentionally disrupting the rest of your account. Growth shouldn’t create instability.

Lastly, your reporting should make simple sense. You shouldn’t need to dig through data or second-guess what’s driving performance. The structure itself should surface insights naturally, making optimisation a continuous, informed process, not a guessing game.

Let’s summarise that quickly:

Allocate budget based on performance and priority
Match search intent to the right products or categories
Isolate high-value products
Scale what works without disrupting everything else
Understand performance without digging through noise

If you can’t do those things easily, your structure is holding you back.

So, let’s get into how you can turn it all around.

Start With Your Product and Category Hierarchy

Your PPC structure should mirror how your business actually makes money – not how your website is built, or how your feed is imported, or even how the platform suggests.

That means grouping campaigns and ad groups around:

Product categories
Margins
Bestsellers
Seasonal ranges
Strategic priorities

So again, your highest-margin products shouldn’t be competing for budget with low-margin, high-volume items in the same campaign. That’s how profitable growth gets diluted.

Instead, segment intentionally and give your top performers room to scale.

Separate Branded, Generic, and High-Intent Traffic

One of the most common structural mistakes is blending different types of search intent into the same campaigns.

Branded searches behave, convert and cost differently, and if you don’t separate them, you lose control over budget allocation, your bid strategy, and those valuable insights into performance that PPC campaigns can give if done well.

At the very least, your structure should clearly distinguish between:

Branded terms
Generic category searches
High-intent, product-specific queries

Each of these should have its own strategy – don’t use a one-size-fits-all approach and hope for the best.

Take Back Control From Over-Automation

Surprise, surprise, leaving it to the bots isn’t all it’s cracked up to be. Automation in platforms like Google Ads can be powerful – but only when it’s guided by a strong structure.

Far too many e-commerce accounts rely entirely on automated campaigns without giving the system the right inputs. This results in poor product prioritisation with little visibility into what’s actually working. It’s a great way to waste spend on low-value queries.

So, automation needs to be used strategically, not as a replacement for a strategy.

That means:

Segmenting campaigns before automation
Feeding clean, structured product data
Layering in exclusions and controls
Monitoring search term quality

If you don’t structure first, automation will ultimately just accelerate inefficiency.

Use Your Feed as a Strategic Asset

Your product feed isn’t just a data source – it’s a core part of your PPC structure.

Small improvements here can bring real wins:

Optimised product titles with high-intent keywords
Clear, consistent categorisation
Use of custom labels (e.g. margin tiers, seasonality, bestsellers)
Clean, high-quality imagery

When your feed is structured properly, your campaigns become more targeted by default.

When it isn’t, even the best campaign setup struggles.

Prioritise What Actually Drives Profit

A common trap in e-commerce PPC is optimising for top-line revenue instead of actual profitability. Without the right structure, platforms will often push spend toward high-volume, low-margin products because they’re easy converters.

Instead of that dodginess, your structure should reflect profit margins, stock levels, strategic product pushes and, where possible, customer lifetime value. Which might mean separating campaigns by margin tier or creating dedicated campaigns for high-profit products so that you can scale the right products, not just the easy sellers.

Make Reporting Work for You

If your reporting is hard to interpret, your structure is too. You should be able to answer questions like:

Which product categories are most profitable?
Where is budget being wasted?
Which campaigns are scaling efficiently?
What search intent is converting best?

…without pulling complex, manual reports every time.

A clear structure creates clear insights, which leads to better decisions.
