Why omnichannel marketing lowers your cost to acquire customers

Executive overview

No single marketing channel can build a large business on its own — every channel eventually saturates, becomes competitive, and gets expensive. Neil Patel argues that brands consistently make the mistake of chasing trendy platforms like TikTok while neglecting proven, high-volume channels such as Google Ads, Facebook, and email. Combining multiple channels is not just a hedging strategy; Expedia's internal data showed that running ads across many channels simultaneously reduced cost per acquisition by roughly 10%, a figure NP Digital still sees hold true today. Paid advertising should be treated as an investment with a measurable return, not avoided as a badge of honour. Businesses that adopt a true omnichannel approach — and optimise for customer lifetime value rather than one-off transactions — consistently outgrow those that rely on a single channel.

The case against chasing shiny channels

• TikTok CPAs were roughly 54% cheaper than Facebook in recent months, yet TikTok cannot yet match Google or Facebook on raw volume.
• "Boring" channels (Google Ads, Facebook, email, SEO) still drive the majority of e-commerce revenue at scale.
• Brands fixate on high-production video creative (e.g. Dr. Squatch-style ads) before testing cheaper UGC content first.
• Testing UGC before committing $50,000+ to a polished production reduces wasted spend significantly.
• Wanting the shiny object instead of mastering the basics is the single most common mistake Neil sees in e-commerce.

Paid ads as investment, not cost

• Hundreds of billions of dollars flow to Google and Facebook annually because advertisers keep spending — proof that returns exist.
• Refusing to run paid ads while competitors do is a guaranteed way to lose market share.
• If a product genuinely helps people, not advertising it is described as "rude" — it limits the number of people who can benefit.
• The correct frame is: spend a dollar, make two; if unprofitable, keep iterating until it works.
• Look at what competitors are spending; if they are profitable, the channel can be made to work in your category too.

Optimising for lifetime value, not instant revenue

• Optimising purely for immediate revenue on ads leads to losses; the real profit lies in repeat purchases.
• Upsells (e.g. upgrading a Big Mac to a meal) and downsells (e.g. offering fries after the meal is declined) raise average order value at the moment of purchase.
• Customer lifetime value (LTV) is the metric that determines whether a paid-acquisition strategy is truly profitable.
• Mapping out the full purchase journey — including post-checkout offers — is essential before scaling ad spend.

The omnichannel CPA reduction effect

• Using Instagram, TikTok, Facebook, SEO, CRO, Google Ads, media buys, and influencer marketing together drives CPA down 9–11%.
• Expedia validated this with an internal brand test: TV, radio, and online ads combined reduced acquisition cost by ~10% across all channels.
• Channels reinforce each other — a customer exposed on multiple touchpoints converts more cheaply than one reached through a single channel.
• The omnichannel effect holds regardless of industry; the principle generalises beyond travel or e-commerce.

Getting started on a limited budget

• With $10,000–$20,000, self-service beats hiring a large agency because more of the budget goes directly to media.
• Shopify templates and affordable online courses for Facebook, Instagram, or TikTok ads lower the barrier to entry.
• Cheap contractors can realistically get a new brand to $5,000–$30,000 per month in revenue.
• Scaling to millions per month requires more expert help; agencies add the most value at that growth stage.
• Something is always better than nothing — early results teach you what messaging and audiences work before budgets grow.

A/B testing and conversion optimisation

• A/B (split) testing shows two different ad or landing-page variations to separate audience halves to find what converts better.
• Emotional creative (aspirational lifestyle) and logical/data-driven creative (comparative statistics) appeal to different buyer types — neither wins universally.
• High-impact test variables include messaging angle, image versus video, and offer framing; button colour alone has minimal effect.
• Tools such as Optimizely, Crazy Egg, and VWO enable structured testing without custom engineering.
• Running tests before scaling spend avoids committing large budgets to an approach that has not been validated.
