After working with hundreds of Amazon Vendor accounts, patterns emerge. The same challenges come up time and again across brands of different sizes, in different categories, at different stages of growth. The details change. The underlying problems are remarkably consistent.
This article sets out the challenges we see most frequently across Amazon Vendor accounts right now, alongside practical guidance on how to start addressing each one. If several of these sound familiar, you are not alone, and more importantly, none of them are unfixable.
Ad spend is spread too thinly across too many SKUs
When budget is distributed across an entire product catalogue, nothing gets enough momentum to rank, convert, or grow meaningfully. The temptation to give every product some ad support is understandable. The result is that nothing gets enough to make a real difference.
The brands scaling profitably on Amazon are not spreading their investment evenly. They are making intentional decisions about which SKUs to back properly and at what level, concentrating spend on the products that have the retail foundations in place to convert that spend into profitable returns, and accepting that some products in the catalogue do not deserve ad investment right now.
The practical starting point is to tier your catalogue. Identify which products have the highest potential for profitable growth. Direct the majority of your ad budget toward those SKUs. Review the rest honestly: some may need their retail readiness improved before they receive ad support, and some may not be worth investing in at all.
Retail foundations are not ready for paid media
Scaling ad spend onto product pages that are not converting is one of the most common and costly mistakes on Amazon. It is what we call a leaky bucket problem. If your listings have weak images, thin copy, low review counts, or poor Buy Box stability, increasing your advertising budget does not drive growth. It makes the problem more expensive.
Before you increase ad spend on any product, look at the listing honestly. What is the conversion rate? How does it compare to your best-performing products in the same category? What is driving the gap?
The areas to audit are the product title, which should be keyword-led, mobile-optimized, and intent-aligned. The bullet points, which should be benefit-led with objection handling built in. The images, which should reinforce USPs, answer frequently asked questions, and highlight differentiation and value. The A+ content, which should be high quality and conversion-focused. The review count and rating, where a minimum of 15 reviews at 3.5 stars is a reasonable baseline for a product ready to receive significant ad investment. And the inventory position, because driving traffic to a product that is about to go out of stock or is already suppressed due to availability issues is a waste of budget regardless of how good the listing is.
Fix the listing before you turn up the volume on ads. The return on that investment is almost always higher than the return on the equivalent amount of additional ad spend.
TikTok Shop and Amazon are managed in isolation
Most brands with a presence on both Amazon and TikTok Shop are managing them as entirely separate workstreams, with separate teams, separate KPIs, and sometimes separate agencies. The customer does not experience them that way.
When a customer discovers your product on TikTok and then purchases it on Amazon, that sale appears in your Amazon data with no credit given to TikTok. Pull back on TikTok because the direct revenue figures look underwhelming and your Amazon branded search volume can drop shortly afterwards, often without an immediately obvious explanation. This is the halo effect, and it is one of the most misunderstood dynamics in multi-channel eCommerce right now.
The practical implication is straightforward. Before making any decision to reduce investment in a channel, look at what happens to your other channels when TikTok activity increases or decreases. Overlay your TikTok content activity against your Amazon branded search volume over the same period. The correlation is often visible enough to tell a clear story about whether TikTok is influencing your Amazon performance even when it is not directly capturing the sale.
The brands building sustainable growth across both platforms are the ones who understand how the channels influence each other and have built a strategy that connects them rather than treating them as competing priorities.
Measurement stops at campaign metrics
ROAS and ACoS tell you about ad performance. They do not always tell you about business performance. Focusing on these metrics alone gives you an incomplete picture of what your advertising is actually delivering.
The metrics worth tracking alongside ROAS are TACOS, which measures your total advertising cost as a proportion of overall revenue rather than just ad-attributed revenue. If your TACOS is creeping up while your ROAS looks healthy, your ads are becoming less efficient across the business as a whole. New to brand metrics, which tell you whether your advertising is actually bringing in new customers or simply capturing existing demand that would have arrived organically anyway. Organic rank, which shows whether your listings and ad activity are building long-term visibility or just buying short-term traffic. And share of voice, which tells you how you are performing against competitors in your category across paid and organic search.
These metrics together tell a fundamentally different story from ROAS alone, and it is usually the story that is most worth acting on.
Strategy is fragmented across teams and agencies
One of the most consistent findings across the Amazon Vendor accounts our team audits is fragmentation. Ads teams focused on efficiency metrics. Retail teams focused on stock and catalogue health. Finance teams reconciling Amazon payments and chargebacks. Leadership pushing for growth targets. Everyone working hard, but not always from the same plan or toward the same commercial goal.
This fragmentation is often more damaging when multiple agencies are involved. An account management agency, a separate ads agency, and a creative agency can each be delivering against their own brief without a shared overarching strategy connecting their work. The result is high activity and low commercial control.
The most effective remedy is to establish a single overarching Amazon strategy that every team and every agency buys into. That strategy should define which products are being prioritised and why, what the commercial targets are at SKU level rather than just account level, how retail readiness and advertising decisions connect to each other, and how success is measured across the full business rather than just within individual campaign dashboards.
Budget decisions are made on the wrong numbers
The most common budget conversation in Amazon Vendor accounts goes like this. Channel X is performing, so more budget goes into Channel X. Channel Y is underperforming, so the agency gets reviewed. A budget line goes up, another gets scrutinised, and everyone leaves the meeting feeling like something got decided.
The conversation that almost never happens is this one: are we converting the demand we already have, before we spend money buying more of it?
In almost every account our Amazon Vendor agency team reviews, there is revenue sitting inside existing traffic that is not being captured: from better conversion rates, smarter placement decisions, or simply stopping spend on campaigns that have not generated a profitable sale in months. That opportunity is almost always larger than what an incremental budget increase would deliver.
Before increasing any budget line, the questions worth asking are these. What is the conversion rate on the SKUs being actively advertised, and what would a two percent improvement be worth in real revenue terms? Which placements are being funded by default rather than because they are earning their budget? What does true contribution margin look like at SKU level, not just blended account ROAS?
More budget is sometimes the right answer. It is rarely the first one.
