BrisTechTonic is a Bristol SEO agency that helps UK businesses get found on Google, the local map pack and the AI assistants they now ask, like ChatGPT and Perplexity. An Amazon ads agency plans, builds and manages your advertising inside Amazon: its main ad types (Sponsored Products, Sponsored Brands and Sponsored Display), plus the ongoing work of blocking wasteful search terms, choosing what to target and setting how much you pay per click. The real skill is not the bidding, it is judging the account by what advertising costs against your total sales, not a flattering per-campaign figure, and by the profit each product actually makes after Amazon's fees, the cost of the goods and returns. BrisTechTonic runs Amazon ads to that number, joined up with how well your products rank naturally and how good your product pages are, with your budget paid straight to Amazon and a fee that does not rise just because your spend does.
Amazon advertising looks like search advertising and behaves like something else entirely. The auction sits inside a shop, next to the buy box, at the exact moment someone has decided to purchase, and the platform owns the demand you are bidding on. That closeness to the sale is why Amazon ads can be so efficient, and why they are so easy to run badly. The temptation is to launch a handful of automatic campaigns, watch the ACoS column, and cut anything that looks expensive. That is how brands throttle their own growth while congratulating themselves on efficiency.

The number that causes most of the damage is ACoS read on its own. Advertising cost of sales measures spend against ad-attributed revenue only, so the cleanest way to improve it is to stop advertising, which also stops the sales velocity that holds your organic rank. Total advertising cost of sales fixes the blind spot: it measures ad spend against your total revenue, so you can see when advertising is genuinely growing the brand and when it is just re-buying sales you would have made anyway. We manage to TACoS and to profit per ASIN after Amazon's fees, cost of goods and returns.
Structure is the other half of the work. Sellers and brands need automatic and manual campaigns feeding each other, a clean flow of converting search terms into exact-match targeting, and negative keywords that stop broad and auto campaigns from bleeding into terms that never convert. Sponsored Brands and Sponsored Display then do the jobs Sponsored Products cannot: defending your listings, retargeting shoppers who bounced, and building category awareness that pure keyword bidding never will.
None of it works if the listings underneath are weak. Ads buy the click, but the title, images, A-plus content, price and reviews decide whether it converts, and a poor conversion rate quietly inflates the cost of everything. We look at listing health before we scale spend, and we will tell you when the next gain is in the detail page rather than the bid. Experienced practitioners run these accounts, between the strategy and the spend.
In ecommerce, a single percentage point is real money.
These are industry figures, not our own results, and we do not invent numbers. In ecommerce the traffic is bought once but converts over and over, so small gains in speed, findability and conversion compound. No outcome is ever guaranteed.
Amazon Ads, broken down.
Account audit and profit model →
We start with what each product actually makes after Amazon's fees, the cost of the goods and returns, then line up your current spend against it, along with what advertising costs against your total sales. Wasted spend, ads that are simply paying for sales you would have made anyway, and neglected best-sellers all come to light here, before we change a single bid.
Campaign architecture
Sponsored Products campaigns set up so the search terms that actually lead to sales get promoted into their own tightly targeted campaigns, with a disciplined system for blocking the search terms that never lead to a sale, so your broader campaigns stop wasting money on them.
Sponsored Brands and category building
Sponsored Brands ads and your Amazon Brand Store used to own the banner at the top of your category, tell your brand story where shoppers see it first, and protect searches for your own brand name, rather than treating every ad slot as just another product listing.
Sponsored Display and retargeting →
Sponsored Display used to show ads again to shoppers who looked but did not buy, protect your own product pages, and compete on rivals' listings, so the interest you have already paid to create is won back instead of lost.
Bidding, placements and dayparting
How much you pay per click, and the extra you pay for prime ad slots, set against the real sales and profit of each product rather than one average target, with the premium for top-of-search slots paid only where the numbers justify it and pulled back where they do not.
Listing health and conversion
Your product titles, images, enhanced product descriptions, pricing and reviews reviewed as the layer that actually turns clicks into sales, because a weak product page pushes up the cost of every click in a way no amount of clever bidding can fix.

What clients say about working with us.
“I've had the pleasure of working with Chris on several SEO projects for my websites in the health field. He was definitely been able to demystify things so that I felt able to make decisions with him and feel confident they were the right ones. For a non-techie, that is worth gold! I look forward to working with Chris again and warmly recommend him to anyone who - like me - is unsure about all things SEO.”
“I was recommended by my branding partner to use Chris and his team last year. I can’t recommend them highly enough. They are very responsive , easy to communicate with and great at translating techy stuff when needed. They are now an essential part of my business model”
“We've been working closely with Chris, Hannah and the team for over 12 months now. As a small company with ambitious growth plans, it was incredibly important that we made the right choice on who to trust with our SEO. 18 months later, we're totally thrilled with our experience so far and our growing online presence within our market. We'd happily recommend BTT and their services to other SMEs. Drop them an enquiry!”

The way we run Amazon Ads.
Audit the account and the economics
We read the campaigns, search-term reports and the profit each ASIN makes after fees, cost of goods and returns. Where is spend cannibalising organic sales, where is ACoS hiding a loss, and which listings are being starved. The maths comes before any bid changes.
Rebuild the structure
Automatic, manual and exact-match campaigns organised so converting terms graduate cleanly, negatives applied to stop waste, and Sponsored Brands and Display added where Sponsored Products cannot reach. The account becomes something you can steer rather than average.
Set targets to profit
ACoS and bid targets set per ASIN against contribution, with TACoS as the account-level guide, so budget concentrates on the products and searches that make money and eases off the ones that merely turn over revenue.
Prove, then scale
We start where the data and margin are clearest, confirm advertising is growing total sales rather than shifting them from organic, then widen spend with evidence rather than optimism, especially into peak events.
Manage against the numbers
Weekly work on search terms, negatives, bids, placements and budget, with spend moved toward what earns profit and stopped on what does not. No set-and-forget, and no defending a losing ASIN in a monthly deck.
Coordinate paid and organic
We track how paid velocity is moving organic rank and adjust spend accordingly, pulling back where organic holds the position and pressing where advertising still does the lifting, so you are not paying twice for the same shelf.
How do we approach Amazon Ads?
TACoS over a tidy ACoS
The headline advertising figure most people watch (called ACoS, or advertising cost of sales) is easy to make look good simply by advertising less. A truer measure is what advertising costs against your total sales, both from ads and from natural sales together (called TACoS). We manage to that broader figure and to the real profit each product makes, so a nice-looking headline number never hides a product that is quietly losing money or a brand that has stopped growing.
Sponsored Products, Brands and Display, used deliberately
Each ad type does a different job. Sponsored Products protects and wins the searches that lead to sales, Sponsored Brands builds your category presence and brand story, and Sponsored Display shows ads again to shoppers who looked but did not buy and holds your own product pages. We use each where it earns its place, rather than spreading budget evenly and calling it coverage.
Advertising and organic rank as one system
On Amazon, sales from ads help push a product up the natural (unpaid) rankings, and a strong natural ranking means your ads have to work less hard. Run the two separately and you end up overpaying to rank for searches you already win for free. We join them up, so ad spend concentrates where it actually lifts your ranking and eases off where your product already holds the top spot without ads.
No markup on your media
Your Amazon ad budget is paid straight to Amazon. Our fee is for the experienced work of running the account well, and it does not go up just because you pushed spend for Prime Day or the Christmas quarter. You always know what is ad budget and what is our management fee.

A free look first
We review what your current agency has done, tell you straight what is worth keeping and where the quick wins are. No obligation to move.

A clean handover
We map the work across, set a plain-English baseline in the first few weeks, and carry on from there. No starting from zero, no quiet ranking gap.
Three-month minimum, then rolling monthly on 30 days’ notice. No long lock-in, no exit fees.
Who runs your Amazon account, and how?
On Amazon, the gap between busy and profitable comes down to who is watching the numbers. BrisTechTonic is the trading name of Bryley Ltd, a team with years of combined experience, and your advertising is run by an experienced operator from profit audit through to weekly optimisation, the same person throughout rather than a cheaper pair of hands once the account is won. We manage to total advertising cost of sales and real profit per ASIN rather than a comfortable campaign ACoS, coordinate paid spend with organic rank, and will tell you plainly when the next gain is in the listing rather than the bid.
Experienced people do the work
The person who audits the account and models the margins is the person who builds the campaigns and cuts the bids each week. No account is left to run itself between the strategy and the spend.
Optimised to real profit
We read Amazon against contribution after fees, cost of goods and returns, guided by TACoS at the account level, not a campaign ACoS the platform is happy to flatter. The numbers we report are the ones your finance team recognises.
Honest about the channel
Amazon ads suit sellers and brands with healthy listings, margin and genuine demand. If your detail pages cannot convert or your economics cannot carry the auction, we say so rather than spend to prove a point.
Amazon Ads: common questions.
What does an Amazon PPC agency do?
An Amazon ads agency sets up and runs your advertising inside Amazon: its main ad types (Sponsored Products, Sponsored Brands and Sponsored Display). The work covers how the campaigns are set up, choosing what to target, blocking wasteful search terms, setting how much you pay per click, choosing ad slots and reporting, all judged against the profit each product makes. We run it against what advertising costs on your total sales rather than a flattering headline figure, join it up with how well your products rank naturally, and pay your budget straight to Amazon with no markup on spend.
What is the difference between ACoS and TACoS?
ACoS (advertising cost of sales) compares your ad spend only against the sales the ads directly brought in, so it looks better the less you advertise. TACoS (total advertising cost of sales) compares your ad spend against all your sales, both from ads and natural sales together. That broader figure shows whether advertising is genuinely growing your brand or just re-buying sales you would have made anyway, which is why we manage to it alongside the profit each product makes.
Do you charge a percentage of ad spend?
No. Your Amazon budget is paid straight to Amazon, and our fee does not go up just because you scaled up for Prime Day or the Christmas quarter. You pay for the experienced work of running the account well, not a slice of your ad budget.
Do you work with sellers and brand-registered accounts?
Both. Sponsored Products is open to most sellers, while Sponsored Brands, Sponsored Display and the Brand Store need you to be signed up to Amazon's Brand Registry (its programme for registered brand owners). If you are registered we use the full range of ad types; if you are not, we make Sponsored Products work hard and can advise on what registering would unlock. Either way the account is run for profit, not just to look busy.
How do Amazon ads affect organic rank?
Sales from ads count towards the momentum Amazon looks at when it ranks products naturally, so advertising can push you up the unpaid rankings, and a strong unpaid ranking means your ads have to work less hard. Run them apart and you overpay to rank for searches you already win. We join the two up, concentrating ad spend where it actually lifts your ranking and easing off where you already hold the top spot without ads.
How is this different from your wider Paid programme?
It is the Amazon-specific version of it. If you also want Google, Shopping, Meta or paid placements on AI surfaces, the Paid & AI ads programme runs them together to one profit model rather than a set of disconnected dashboards.
