Why Q4 Is Harder Than Ever for Google Ads - How to Fix It

The Q4 Myth: More Spend on Google Ads = More Sold Products

The assumption is simple: everyone’s buying, so it must be the best time to spend big on those ads. But that logic only works when everyone else isn’t doing exactly the same thing.

This year, CPCs hit record highs across most ecommerce verticals. The competition for clicks has never been fiercer, and with Performance Max campaigns bidding across multiple channels, advertisers were often competing against themselves without even realising it.

Why? Because when everyone floods the auctions at once, efficiency disappears.

AI-driven bidding like Performance Max doesn’t automatically know which products truly drive profit — it chases conversions. Without human oversight and data-led SKU segmentation, you can easily end up funding low-margin clicks.

Why 2025 Q4 is Harder Than Ever

This Q4 wasn’t just “busy” — it was structurally different.

Automation Overload without a human touch
With Google pushing full automation through Performance Max and Smart Bidding, marketers have less visibility and control than ever. The result? Budgets burned on irrelevant placements or low-intent audiences.
Feed Fatigue - not finding the specifics
Many accounts went into peak season with stale or incomplete product feeds. Missing attributes, poor categorisation, and generic titles can quietly kill performance when competition tightens.
Consumer Demand no longer peaking
Shoppers are more cautious, spreading their spending and browsing across a much longer period. Instead of “Black Friday week,” it’s now a rolling six-week cycle of discounts — stretching budgets thinner.
Neglected Products taking the back seat from the usual high performers
Every account has products that could perform but never get the attention they deserve. When the focus is purely on top sellers in Q4, those long-tail SKUs never get the optimisation they need — and that’s untapped revenue.

Q4 Is a Test — Not a Strategy

The brands who win in Q4 aren’t the ones with the biggest budget. It’s the ones who already arrived at Q4 with a tried and tested feed, learned fast what works, and optimised their Google Ads continuously.

That’s why we’ve seen a clear trend in our Google Ads client data this year: brands that invested steadily throughout the year saw stronger Q4 results without needing to inflate spend. Because by the time the seasonal surge arrived, our software had so much clean data that their bids were already efficient.

In short — they rocked up to Q4 ready for anything.

Why It’s Too Hard to Go At It Alone - Q4, that is

Automation is powerful, and very on trend, but it’s also unpredictable. Managing thousands of SKUs, analysing SKU-level profitability, and staying ahead of bid shifts isn’t something one person can realistically do even with the help of a trusty AI buddy.

That’s where Bidnamic comes in.
