"I have to advertise on TikTok, everyone does." That's often how people choose, and often how they lose their first budget. Each ad platform is built for a different buying behaviour. Putting a product on the wrong channel means paying to show it to people who aren't in the right frame of mind to buy it.
The deciding question: searched for or discovered?
There are two ways to buy online.
People search. Your customer knows what they want, or has a precise problem: "adjustable laptop stand", "non-slip yoga mat". They type it into Google. That's existing demand, and Google is the channel that captures it.
People discover. Your customer didn't know your product existed. They see it in their feed, they stop, they want it. That's created demand, and Meta, TikTok or Pinterest are the channels that spark it.
To find out where you stand, search Google for your product name and the problem it solves. If stores are already running Shopping ads there, demand exists. If you find almost nothing, it's probably a discovery product.
The product-to-channel table
| Your product | Main channel | What it takes to succeed |
|---|---|---|
| Already searched for (name, category, precise problem) | Google Shopping, then Search | A clean product feed, a page that answers the search |
| Visual and desirable (fashion, beauty, decor, gifts) | Meta (Facebook and Instagram) | Several images or videos, refreshed regularly |
| Understood by seeing it work (gadget, skincare, transformation) | TikTok | Short, native videos shot on a phone |
| Part of a project or inspiration (decor, weddings, recipes) | Vertical visuals, a catalogue | |
| Passion niche (gaming, fishing, model making) | Creators and communities, then Meta | Partnerships and credible content |
| Customers who already visited your store | Retargeting and email | An installed pixel, an email list |
The same product can work on several channels. This table gives you a first choice, not a truth: your numbers will decide.
What each channel requires
Google Shopping. Your products appear with photo and price when someone searches. You need a Merchant Center account linked to your store (Shopify's Google & YouTube app does this), titles and descriptions using your customers' words, and a competitive price, since your customer compares side by side. Details in the Google Shopping and Performance Max tutorial.
Meta. You show your product to people who weren't looking for it. You need creatives that stop the scroll, refreshed often, and a pixel that reports purchases. Details in your first Meta Ads campaign.
TikTok. Same logic as Meta, but in vertical video, with more natural codes. A video that looks like an ad performs poorly. Watch the budget: TikTok requires a minimum of $50 per day per campaign and $20 per day per ad group. Details in the TikTok Ads tutorial.
Pinterest. People go there to plan a project. The path is longer, but pins keep bringing visitors for months, even without paying.
Before spending the first euro
Whatever the channel, three things must be ready:
- Your pixel installed and checked, to know which ads sold. Without it, you're flying blind, and the platform doesn't know who to show your ads to. See install your Meta and TikTok pixels on Shopify.
- Your minimum ROAS worked out, to know when a campaign makes you money. The break-even ROAS calculator gives it to you in a minute.
- A store that converts, because ads amplify what exists. If your store doesn't sell with free traffic, ads will just lose money faster. The previous chapter, starting with sell the problem, not the product, is there for that.
Why start with one channel
Every platform learns from the purchases it observes. Meta explains that an ad set needs about 50 optimisation events, purchases for example, over seven days to exit its learning phase. Splitting a small budget across three channels stops each one from learning, and leaves you unable to conclude anything.
Pick the most logical channel for your product, give it a real test, read your numbers, and only add a second channel once the first holds up.
Classic mistakes
- Choosing the trendy channel rather than the one where your customer buys.
- Launching without a pixel, then not knowing what worked.
- Judging in two days a campaign that hasn't had time to learn.
- Sending ads to the homepage instead of the product page that continues the message.
- Advertising a store that doesn't convert, hoping volume will make up for it.
