Beyond Google: Why Multichannel PPC is the Key to Scalable eCommerce Growth

Google Isn’t the Only Game in Town (It’s Just the Loudest)

It’s tempting to throw all your PPC chips in with Google and call it a day. After all, they’re massive, and shoppers do search there. But here’s the cold truth: if you’re pinning all your growth hopes on Google alone, you’re speed-limiting your eCommerce rocket. Worse still, you’re one algorithm update or rising CPC away from a profit nosedive. The idea that “if it isn’t Google, it isn’t worth advertising on” is dangerously out-of-date.

Customers don’t live their lives on just one channel, so why do so many brands still put their entire PPC budget into the world’s nosiest search bar?

The Real-World Risks of the Google-Only Approach

Sure, Google’s got reach. But it’s not got everything. Here’s what single-channel thinking really gets you:

• Sky-high competition and increasing ad costs. Google Ads costs have climbed so aggressively in the last few years, it’s almost as if Google knows it’s the default.

• Limited customer reach. Your dream buyers aren’t just searching—they’re discovering, scrolling, and being influenced everywhere from TikTok to shopping on Amazon to lurking in Facebook groups.

• Unwelcome surprises when Google changes the rules or suspends accounts. Whole brands have been knocked flat, overnight, with no backup plan.

Ask yourself: If Google Ads stopped working for you tomorrow, how long would your eCommerce business keep growing? If your honest answer is “not long,” it’s time to diversify.

Multichannel PPC: Build More Lanes, Grow Faster

Here’s a spicy stat: brands active on three or more marketplaces see an average growth in Gross Merchandise Value (GMV) of 104%. No, that’s not a typo. And if you want to get even bolder, brands running multichannel campaigns (using four or more platforms) average a 300% increase in ROI compared to those who stick to the classics.

Let’s break it down:

• Multichannel campaigns mean more eyes on your products, in more places, across every stage of the buying journey.

• Not every shopper is a Google fanatic. Some discover on TikTok, compare on Facebook, then buy on Amazon. If you’re invisible in those moments, you’re out of the running.

Don’t believe us? In the fashion industry, 44% of major eCommerce retailers deliberately split their ad budgets between Facebook and Google Shopping. Two channels, double the fun—and double the revenue touchpoints.

How Multichannel Actually Works for eCommerce

Each platform isn’t just a different logo—it’s a different customer mindset. Let’s run through a few:

• Meta (Facebook & Instagram): World-class at finding “lookalikes” and impulse buyers, unbeatable for retargeting and social proof.

• TikTok: The reigning king of making products go viral (and selling out overnight). If Gen Z and younger millennials are your buyers, ignore TikTok at your peril.

• Microsoft Ads: Yes, Bing still exists. And its audience—older, with more disposable income—converts surprisingly well. Lower CPCs too.

• Amazon Ads: Skip the “window shopping” phase and target buyers hot and ready to buy, already searching within a marketplace.

• Snapchat, Pinterest, X (formerly Twitter): Niche? Maybe. Irrelevant? Absolutely not, depending on where your core customers hang out.

The point: Multichannel isn't about copy-pasting your Google Shopping feed everywhere else. It’s about using each platform’s strengths to catch customers wherever they happen to be on their path to purchase.

But Isn’t Multichannel PPC a Total Headache? (Yes and No)

No sugar-coating: multichannel is more complex than “Set and forget on Google.” You’re juggling creative formats, bidding strategies, audience segmentation and learning curves for every platform.

Enter technology: Modern PPC tools, automation and AI-powered campaign managers (like Google Performance Max, Meta Advantage+, Amazon Performance+) can streamline the chaos, cutting busywork and making more room for strategy.

But don’t get lazy. Platform AI only goes so far. Most of the big “easy” solutions are platform specific—great if you just want to run ads in one walled garden, less great if you want a portfolio that stretches across the internet.

To really win, you’ll need tech that enables:

• Centralised campaign and feed management across platforms

• Cross-channel analytics (so you see what’s actually making you money)

• Creative generation tools tailored for different ad formats and audiences

Multichannel PPC Best Practices (Don’t Just Spray and Pray)

Just because your campaigns can show up everywhere doesn’t mean they should—not without a plan.

1. Get Your Data House in Order Forget “set and forget.” Make sure your tracking, attribution, and customer data flow cleanly across all channels. Otherwise, your ROI reporting will be as useful as a chocolate teapot.

2. Customise Every Campaign Craft creative and copy for the platform it runs on. Your TikTok ad needs a wildly different vibe to your Microsoft Ads creative.

3. Align Channels with Customer Journey Social channels for awareness; search for intent; marketplace ads to clinch the sale. Map your budgets to stages of the journey, not just random “channels.”

4. Test, Measure, Optimise, Repeat Multichannel isn’t a one-and-done exercise. Consistently review performance, shift budgets, and test creative formats.

5. Protect Against Algorithm Chaos No more sleepless nights worrying about Google algorithm “surprises.” When your revenue is diversified, a change in one channel is a hiccup, not a disaster.

Nitty-Gritty: Implementation Tips for Scale

• Pick Your Channels Carefully Not all platforms fit every product. B2B? Try LinkedIn and Microsoft. Beauty or apparel? Instagram, TikTok, and Pinterest. Amazon for product-aware buyers looking to shop.

• Invest in Cross-Channel Tech Early Don’t try and run five separate dashboards manually. The right tool pays for itself in hours saved and insights gained.

• Retarget Everywhere Sync your customer lists across platforms for omnipresent retargeting. Buyers need multiple nudges, in multiple places.

• Get Creative (Literally) Cross-posting isn’t optimal—native creative always outperforms the lazy stuff.

Future-Proof Your eCommerce Brand

Here’s the harsh reality: eCommerce is only getting noisier—and the next algorithm shake-up is always around the corner. Brands that master multichannel PPC aren’t just spreading their risk, they’re opening the doors to compound growth and true brand resilience.

So, keep betting big on Google—just don’t bet the farm. The future is blended, messy, and more profitable than ever (if you play it right).

Ready to actually scale, stop fearing “what if Google shuts us down?” and build a brand that grows—no matter where your shoppers are hanging out?
