Your conversion hates this "trick": External traffic and Google Ads explained for Amazon FBA merchants

Many people believe that high traffic leads to high sales. It sounds logical—more visitors to your products means more sales. However, this assumption is flawed as soon as you drive external traffic to your Amazon listings.

Amazon as a massive search platform—with significant buyer influence

Amazon isn't just an online store. It's a search engine for potential buyers. Anyone searching for a product (e.g., "teapot") goes directly to Amazon, and in 99% of cases, they're actually looking to buy. These users are already close to making a purchase decision(warm traffic).

If you spend money on Facebook, Instagram, or Google Ads, it’s a different story. These users are usually in private mode, casually scrolling through their feed, and come across your ad by chance. The likelihood that these people are in urgent need of your product is very low. This is called cold traffic.

The dangerous conversion issue with external traffic

Let's imagine the following scenario: You run a Facebook ad for your teapot. The user thinks, "Actually, I don't need a new teapot, but it looks nice!" He clicks on your ad, lands on your Amazon listing, and... leaves the page without buying.

‍

Many visitors from "cold" traffic don't make a purchase. Your conversion rate drops, Amazon notices this and concludes: "The product doesn't seem interesting." This results in your listing ranking lower. Less visibility means fewer organic sales and less revenue in the long run. It's a vicious cycle. Retailers end up trying to offset the downward trend with more advertising, which only makes the situation worse.

Important insight: Too much external traffic without a direct intention to buy will lower your conversion rate and harm your Amazon ranking in the long run.

How Google Ads Work for Amazon Products

At first glance, the idea sounds good: with Google Ads, you can direct people to your Amazon product in a targeted way. In practice, however, many people click on the ad without really knowing what they’re getting into. They see no price, no product image, and don’t even know what to expect on the landing page. Here, too, cold traffic encounters your offer.

Many people click just out of curiosity, without any real intention of buying. As a result, you spend a lot but sell very little.

‍

The negative effects on Amazon conversion rates and rankings

Google Ads sends visitors to your listing who aren't even sure they've found the right product. Hardly anyone buys, your conversion rate plummets, and Amazon penalizes your product.

The result: high advertising costs, low conversion rates, and a search ranking that can only be improved through costly measures. As a result, your marketing budget runs the risk of being depleted without delivering tangible results.

‍

Why Google Ads directly on Amazon listings aren't a good idea

The quality of your visitors is crucial. It’s not enough to simply attract large numbers of people to your listing. If most of them aren’t genuinely interested in buying, it will do more harm than good.

Conclusion: Quality traffic trumps quantity. If you run Google Ads, you need to know what you're doing—otherwise, you'll waste money and damage your standing on Amazon.

Your own online store as a traffic destination—here's how it works

Instead of sending traffic directly to Amazon, invest in your own online store. Why? This is where you build trust and can showcase your brand more effectively. Prospective customers who don't buy directly from your store often search for your product on Amazon because they know Amazon as a reliable shopping platform.

Example: Wahu (Niklas Gruno):
Wahu first set up its own store. When the product was then listed on Amazon, sales there skyrocketed—without any additional advertising on Amazon. The brand traffic that ends up on Amazon is considered "warm" traffic. Amazon recognizes that people are actively searching for your product and making purchases. This boosts your ranking.

‍

Advantages of this strategy for Amazon sellers

• You become less dependent on Amazon because you develop a second source of income.
• Stronger branding not only helps in-store, but also on Amazon (customers recognize and trust your brand).
• More organic sales on Amazon, because prospects who are warmly welcomed are more likely to buy.

This strengthens your business in the long term with minimal risk. If you build up traffic strategically, you can use Facebook or Google Ads for your own store while also benefiting from Amazon.

Tip: Drive traffic to your store, introduce visitors to your brand, and then let them visit Amazon on their own. This builds trust, ensures consistent sales, and protects your Amazon ranking

Engage your existing customer base: How to attract warm traffic

Instead of directing random Facebook users to your listing, reach out to the people who have already purchased from you. Actively collect your customers' email addresses.

Here's how to do it step by step:

1. Include a note with each product, for example, saying "Sign up here to get a discount."
2. Offer real added value, such as a free e-book, an extended warranty, a discount, or exclusive access to new products.
3. Build an email list of real customers.

Use this list to provide targeted information about new products or promotions. Customers are familiar with your brand, have already made a purchase, and are much more receptive to your offer(warm traffic).

Advantages of this method:

• Direct, personalized marketing with no waste.
• Higher conversion rates and better ratings.
• A faster launch for new products through targeted launch campaigns.

Prerequisite: a suitable product range and authentic branding

Ideally, pair products that complement each other. For example: If you sell a crib, a stroller is the next product that will interest the same target audience. This allows you to promote both products through targeted newsletters and achieve better results.

If, on the other hand, you sell a hedge trimmer and then a crib, it doesn't make sense. Your target audience is too different, your brand seems inconsistent, and your messaging is all over the place.

How can you improve your conversion rate?

Targeted email marketing traffic ensures that visitors come to your Amazon listing with genuine interest and a willingness to buy. These conversion rates are typically higher than those from cold Facebook or Google traffic. You also build a community of loyal shoppers who keep coming back.

To implement:

• Systematically build up the contact list.
• Regularly provide existing customers with relevant, tailored offers.
• Communicate clearly and create opportunities for repeat purchases, such as introductory discounts or exclusive promotions.

This strategy serves as a natural safeguard against declining conversion rates and poor search rankings.

Many retailers don't initially consider the consequences of a drop in traffic. The effects often don't become apparent until months later, when organic sales plummet and search rankings are overtaken by competitors.

The most common mistakes:

• Too much irrelevant traffic directed to the Amazon listing
• No distinction between store traffic and Amazon traffic
• No customer contact information (no email list)

The consequences are clear: conversion rates drop, Amazon ranks you lower, and growth either fails to materialize or collapses. It often takes a significant amount of time and advertising budget to reverse this trend—and retailers often realize this too late.

Important: The problem is not with the external traffic itself, but with the incorrect targeting and the lack of a strategy behind it.
