Bol.com Sponsored Products for Beginners (2026)

A good listing gets you found. Advertising gets you in front of more of the people searching. On bol that means Sponsored Products: you promote chosen items in search results and in other places across bol, and you pay when someone clicks. This guide explains how it works using bol's own guidance, how to read ACoS against your margin, and what to do first.

We manage bol and Amazon ads at NyxWorks, so our prices are in here. All facts about how bol's advertising works come from bol's partner platform, linked at the end. Where something is our opinion, we say so.

Prices, fees and rules in this article were checked on 19 October 2026. They can change, so check the linked pages before you decide.

What Sponsored Products is

Bol's Advertising via bol offers three tools: Sponsored Products, Branded Shelves and the Brand Page Creator. This guide is about the first.

Sponsored Products is a self-service tool that links the search terms of existing and potential customers directly to your items. Bol says it helps your items show up at the top of search results and in other places across bol. The ads can be used for several purposes, according to bol: advertising your bestsellers, new items, a wide range, or leftover stock.

Bol also says that 78% of all clicks on product pages come from the first page of search results, and 60% from the top 10. That is bol's own figure, so read it as bol's argument for visibility, not as a promise about your results.

Before you advertise: the conditions

Bol sets conditions for Advertising via bol:

The item you advertise must be in the Buy Box.
The content must be complete. Bol names the brand matching the item, a good categorisation and a correct publisher mention.
The item must be allowed to be advertised. Some items, such as infant formula and certain medicines, are not eligible because of regulations. Bol points to the Advertising Code Authority for the overview.

That is why our process starts with an audit of listings, keywords, pricing and ad spend before we touch a campaign. An ad that sends clicks to a weak page pays for the click and loses the sale. Our guide to optimising a bol.com product listing covers the page itself, and how to sell on bol.com covers the account.

How you pay

Sponsored Products works on a cost-per-click (CPC) basis. You bid the maximum amount you are willing to pay for a click, and you pay when a customer clicks your ad. Showing the ad is free. The more competitive your bid, the greater the chance that your ad is shown when a customer searches for your item.

In your seller account you set budgets yourself, per campaign, per day and per month. Bol's tip is to set a daily budget, so you always know your maximum daily cost. If the daily budget runs out, the campaign pauses automatically and resumes when new budget is available. Bol recommends a generous daily budget so ads stay visible throughout the day.

The cost of a campaign is the number of clicks multiplied by the cost per click.

ACoS, ROAS and TACoS: the numbers to know

Bol defines the main metrics like this:

Metric	What it is
ACoS (Advertising Cost of Sales)	The percentage of advertising costs relative to the revenue you achieved through Sponsored Products
ROAS (Return On Ad Spend)	The ratio of your advertising revenue to your advertising costs
TACoS	The relationship between advertising costs and total revenue, both organic and via ads: (advertising costs ÷ total revenue) × 100
Conversion	A purchase that follows your ad within 14 days

Bol notes that ACoS is calculated on costs and revenue excluding VAT. VAT does still affect your total profit.

Here is the rule that matters most for a beginner, in bol's own words: determine your ideal ACoS depending on your goals, profit margins and other costs. If your profit margin is 20%, your ACoS must be lower than 20%, otherwise the advertising costs eat into your profit.

A worked example, as an illustration with made-up numbers: if you spend €10 on ads and the ads bring €100 in revenue excluding VAT, your ACoS is 10% and your ROAS is 10. If your margin before advertising is 20%, you keep about 10% of that revenue after the ad cost. At 20% ACoS you break even, and above it you lose money on those sales. ROAS is simply 1 divided by ACoS: a 20% ACoS equals a ROAS of 5.

The margin to compare against is your margin after commission, product cost, shipping or fulfilment and returns, not the sticker price. If your margin is very thin, there is little room for ads. That is arithmetic, not a bol rule.

Choose a goal and a campaign type

Bol describes four strategies and recommends combining them (a hybrid strategy):

Feature your bestsellers, ideally on both list pages and item pages, with the best-performing keywords added manually.
Use new items. New items can take a long time to get impressions, clicks and conversions, so an advertising boost raises visibility and organic discoverability.
Use your remaining stock.
Feature all your items, with campaigns split by category or performance.

There are two campaign types:

Automatic. For beginners, bol suggests this. You enter the items, your daily budget and your target ACoS, and the system does the rest.
Manual. You choose keywords, categories and product pages yourself and adjust bids per placement, which gives you control per keyword, category and product page.

Give it time

Bol's advice on patience is specific:

Let a campaign run for at least two weeks, or until each item or keyword has generated about 80 to 100 clicks, before you make your first improvements. Then let it run at least another two weeks so the changes take effect.
Check your campaigns weekly and plan at least 1.5 hours a week for monitoring.

What to change, and when

Bol's tips for improving a campaign by KPI:

ACoS too high on an automatic campaign: lower your target ACoS for cheaper clicks, knowing it may mean fewer impressions.
ACoS below your target: consider raising the target ACoS and the daily limit to create more room to bid, which can lead to more impressions.
On a manual campaign: lower the bid on keywords with high costs and low revenue, and on categories or product pages that generate little. Raise bids on your best-performing keywords, categories or product pages.
To increase impressions: the fastest way is a higher bid, a higher target ACoS or a higher daily limit.
To increase conversion: offer a sharper price than similar items from other providers on bol, strengthen the content with customer reviews, and use professional, clear images.

Doing it yourself or having it managed

Bol says it works with many agencies that can help, from fully outsourcing campaigns to concept development. Managing campaigns takes regular time: bol advises at least about 1.5 hours a week for monitoring alone.

Here is what we offer (first-year prices as published on 19 October 2026, excluding VAT, 20% below our standard rates), from our marketplace management page:

Service	First-year price	Standard rate	What it covers
Ad campaign setup	€299	€374	One-time build: campaign structure, keyword research and first launch. No ongoing management
Monthly ads & listing management	€500 per month	€625	Weekly optimisation and a monthly report. Alternatively 15% of ad spend with a minimum of €300 per month, if you would rather it scale with your budget

The ad budget itself is paid by you directly to the platform, and we do not mark it up. We work inside your own seller account, at the access level you are comfortable with. The account has to be registered under your own business, and that cannot be done on your behalf. On a managed store we also check pricing, stock alerts, reviews and budget daily rather than monthly. If you want to talk it through first, a 30-minute consultation costs €30.

A first-campaign checklist

The item is in the Buy Box and its content is complete.
You know your margin after commission, product cost, shipping or fulfilment and returns, and from it the highest ACoS you can afford.
You chose a goal: bestsellers, new items, remaining stock or a broader range.
You started with an automatic campaign, with a daily budget you are comfortable with.
You wrote down the date of your first review: two weeks or about 80 to 100 clicks per item, whichever you reach later.
You planned the weekly check.

Frequently asked questions

How much does it cost to advertise on bol?

You pay per click. You choose the maximum bid per click and set budgets per campaign, per day and per month. Showing your ad is free.

What ACoS should I aim for?

Lower than your profit margin. Bol's own example: with a 20% margin, ACoS must be below 20%. Your ideal ACoS also depends on your goals and other costs.

How long before I change anything?

Bol suggests at least two weeks, or until each item or keyword has about 80 to 100 clicks, before the first improvements.

Do I need ads if I rank on page one already?

That depends on your goals. Bol lists advertising bestsellers among its uses, and says extra traffic to your product page improves your organic search ranking. Look at your own numbers before you decide.

Is it worth it for low-margin items?

Only if the numbers allow it. Your ACoS has to stay below your margin, so thin margins leave little room.
