How to Optimise a Bol.com Product Listing: Titles, Keywords, Images and Conversion
Your product is live on Bol.com, but the sales aren't where you expected them to be. Shoppers may be overlooking your listing in search results, clicking through without buying, or choosing a competitor selling a similar product.
The frustrating part? Lowering your price or spending more on advertising won't necessarily fix the problem. If your product title is unclear, important specifications are missing, or your images fail to answer customers' questions, you could be losing sales before shoppers even consider your offer.
The solution starts with identifying what's holding your listing back.
In this guide, you'll learn how to optimise a Bol.com product listing step by step, from keyword research and product titles to images, descriptions and conversion. You'll also discover how to identify common listing problems, prioritise improvements and measure whether your changes are making a difference.
Whether you're launching a new product or trying to improve an established listing, these practical steps will help you build a stronger product page without relying on guesswork.
What Is Bol.com Product Listing Optimisation?
Product listing optimisation is the process of improving the information and presentation of a product page to make it more useful to shoppers.
On bol.com, this means reviewing elements such as:
- Product titles and relevant search terms
- Product attributes and specifications
- Main images and additional product photos
- Product descriptions and buying information
- Product variations and catalogue accuracy
- Price, stock availability and delivery expectations
The goal is twofold: help relevant shoppers discover your product and give them the information they need to make a purchase decision.
Bol.com explains in its official product information guidelines that complete product information can improve visibility both within bol.com and in external search engines such as Google.
That doesn't mean adding more text automatically improves rankings. The information must be relevant, accurate and appropriate for the product category.
1. Write a Clear, Searchable Product Title
Your product title is one of the first things a shopper sees in search results. It should communicate what the product is and distinguish it from similar options.
A common mistake is treating the title as a place to insert as many keywords as possible. A long, repetitive title can make the product harder to understand without giving shoppers a useful reason to click.
A Practical Title Structure
Depending on the product category, a useful starting point is:
Brand + product type + model or key specification + distinguishing feature
For example, imagine a reusable water bottle.
Less effective:
Stainless Steel Water Bottle Bottle Sports Bottle Leakproof Best Drinking Bottle 750ml
More effective:
Nordra RVS drinkfles - 750 ml - lekvrij
Illustrative example. Nordra is a fictional brand, and the product features should only be used if they are accurate.
The second title identifies the product, gives a meaningful specification and highlights a useful feature without repeating the same terms.
Bol.com recommends including the brand where applicable, the model or type number, the product category and one or two distinguishing features. Its general title guidance also advises keeping titles to 70 characters or fewer, avoiding excessive adjectives and promotional statements, and following the recommended structure for the relevant category.
Read the current Bol.com product title guidelines before updating your listings, as category-specific requirements may differ.
How to Improve Your Product Titles
Start by asking three questions:
- Does the title clearly identify the product?
- Does it include the specifications customers use to distinguish between similar products?
- Can someone understand it quickly without reading it twice?
Also consider the language of your target market. If you sell to Dutch shoppers, use accurate Dutch product terminology rather than inserting English terms simply because they appear to be popular.
A useful rule: Write for the customer first, then check that the title includes the most relevant search language.
2. Research Keywords Before Editing Your Listing
Keyword research helps you understand how shoppers describe the products they want to buy.
For Bol.com, begin with the search behaviour and product terminology relevant to your category. Avoid assuming that the words you use internally are the same words your customers use.
Where to Find Useful Keyword Ideas
Bol.com Search Trends
Check the available search trend information in your seller account. It can help you understand relevant searches and identify opportunities within your product range.
Bol.com Search Suggestions
Start typing a product-related query into the search bar and review the suggested phrases. Treat them as research ideas, not guaranteed search-volume data.
Competing Product Listings
Review listings for comparable products. Notice the terminology used in their titles, the specifications they highlight and the questions their descriptions answer.
Do not copy competitors word for word. Their listings may contain mistakes, outdated information or terms that are not appropriate for your product.
Customer Questions and Reviews
Where available, these can reveal points of confusion, missing specifications and features customers care about. Use this information to improve clarity rather than simply collecting more keywords.
Where Should the Keywords Go?
Prioritise relevance when deciding where to use a search term.
| Listing Element | What to Prioritise |
|---|---|
| Product title | Product identity and key distinguishing features |
| Product attributes | Accurate specifications and category-relevant values |
| Product description | Benefits, usage, compatibility and important details |
| Images | Clear visual evidence of the product and its features |
Do not force every keyword into the title. Use the appropriate product attributes and description fields to communicate additional information.
Bol.com also advises sellers to use relevant keywords without overdoing them. More words do not automatically mean more visibility.
3. Complete Every Relevant Product Attribute
Product attributes are the structured details that describe an item, such as dimensions, colour, material, capacity, compatibility or model number.
They may seem less important than the title or main image, but they help shoppers understand what they are buying and compare suitable options.
Imagine selling a laptop stand. A shopper might need to know:
- Whether it is compatible with their laptop size
- Its height and width
- The material it is made from
- Its maximum supported weight
- Whether it folds for storage
If this information is missing, the shopper may choose another product that is easier to evaluate.
A Simple Attribute Optimisation Process
First, open the relevant item in your Bol.com seller account and review its product information.
Second, check which mandatory and optional fields apply to its category.
Third, fill in all applicable fields using accurate, consistent values. Do not guess specifications or enter irrelevant information just to make the listing appear more complete.
Finally, check whether the displayed product information matches the actual item and its packaging.
Bol.com organises product information into basic, mandatory and optional levels. Completing relevant optional information can help customers make a better-informed decision, while mandatory fields are necessary for an item to be published.
One important limitation: improvements to product content do not guarantee that every change will immediately appear on the live product page. Bol.com's content processing and catalogue rules can affect how submitted information is displayed.
4. Improve Your Product Images
Customers cannot physically inspect a product before purchasing it online. Images therefore need to do more than make a listing look attractive: they should help shoppers understand the item and decide whether it meets their needs.
Start with the main image.
Follow the Main Image Requirements
According to Bol.com's official image guidelines, the main image must meet specific technical and presentation requirements.
The general requirements include:
- A file size between 30 KB and 10 MB
- Dimensions between 500 × 500 and 6,000 × 6,000 pixels
- A white, neutral background without visible shadows
- A clear view of the product outside its packaging, where applicable
- No promotional text, watermarks, logos or icons in the main image
- No lifestyle scene as the main image
Bol.com also notes that the zoom function works with images of at least 1,200 × 1,200 pixels.
Always check the current rules for your product category before uploading or replacing images.
Use Additional Images to Answer Buying Questions
After the main image, use the available image slots to communicate useful information.
Depending on your product, additional images could show:
- The product from different angles
- Important details, materials or construction
- Dimensions or scale
- What is included in the package
- The product in a relevant setting, where permitted
- How the product is used
For example, a storage organiser may look attractive in its main image, but shoppers might also need to see its internal dimensions, drawer layout and construction.
Each additional image should provide useful information rather than repeat the same view.
Think of Images as Part of the Sales Process
Ask yourself what a customer would want to inspect if they could hold the product in a physical shop.
Then use your image gallery to answer as many of those questions as the platform's rules allow.
Do not use images to imply that accessories are included when they are sold separately. Accuracy is more valuable than an attractive but misleading presentation.
5. Write Product Descriptions That Help Customers Decide
A product description should answer the questions that remain after someone has read the title and viewed the images.
It is not an advertisement filled with superlatives. It is an opportunity to explain what the product does, who it is suitable for and what the customer can expect.
Structure Your Description Around Customer Questions
A useful description can cover:
What is the product?
Explain the item clearly, including its intended purpose.
What problem does it solve?
Describe the practical benefit of using it. Be specific rather than relying on generic statements such as "perfect for everyone."
What are its key specifications?
Include relevant measurements, materials, capacity, compatibility or technical details that are not already adequately communicated elsewhere.
Who is it suitable for?
Explain the intended use and any important limitations.
What is included?
List the contents of the package and clarify whether accessories, batteries or other components are included, where relevant.
Turn Features Into Clear Benefits
Consider these two examples.
Feature: The storage box has a capacity of 12 litres.
Clearer explanation: Its 12-litre capacity provides space for storing household accessories, craft materials or other suitable small items.
The second version explains why the specification may matter to a buyer without making unsupported performance claims.
Keep every statement accurate. Bol.com's content rules require product information to be objective and not based on temporary promotional messages. Avoid exaggerated claims, unsupported comparisons, irrelevant keywords and statements that cannot be substantiated.
You can read the official guidelines for writing a clear product description before revising your content.
6. Check Product Variations and Catalogue Accuracy
Listing optimisation is not only about rewriting titles and descriptions.
If you sell the same product in different sizes, colours or configurations, make sure each variation is represented correctly and follows the relevant Bol.com catalogue rules.
For example, if a customer selects a blue version of a product, the displayed images and specifications should correspond to that version wherever required.
Check that:
- Product identifiers and specifications are correct
- Variations are grouped only where appropriate
- Images correspond to the relevant product or variation
- Package contents are clearly explained
- Product information does not contradict itself across fields
Incorrect product information can create confusion, increase avoidable customer questions and undermine trust.
If you sell products that already exist in the Bol.com catalogue, remember that the content shown on a shared product page may be affected by the platform's catalogue and content-selection processes. You may not have unrestricted control over every displayed field.
Review the live page after submitting changes and check your seller account for feedback where something does not appear as expected.
7. Remember That a Better Listing Is Only Part of the Equation
A listing can be complete and professionally written without generating the sales you expect.
Why? Because shoppers also evaluate the offer itself.
Bol.com's Buy Box process considers factors that include product availability, condition, price including shipping costs and VAT, delivery conditions, and the seller's quality score. The relative importance of these factors can differ between product categories.
This is why listing optimisation should be part of a wider marketplace strategy.
Consider the following situations:
Your product gets few clicks.
Review the main image, product title and how clearly the product is presented in relevant searches.
Your product gets clicks but few sales.
Examine the description, missing information, images, price and the overall competitiveness of the offer.
Your product information looks good but sales remain inconsistent.
Check availability, delivery promises, your seller account's quality information and changes in the competitive landscape.
Your product sells, but the margin is too low.
Review profitability before reducing the selling price further or increasing advertising spend.
Not every sales problem can be solved by rewriting a title. Identifying the actual problem first will help you prioritise changes more effectively.
For more information, consult Bol.com's official Buy Box guidance.
8. Measure What Changes After Optimisation
Once you have improved your listings, you need a way to assess whether the changes are helping.
Before editing a product, record the relevant baseline metrics available in your seller account. Depending on your account and the reporting tools available, these may include sales, conversion information and Buy Box data.
Then review the results after allowing enough time for meaningful observations.
A Practical Measurement Framework
| What You Observe | What to Investigate |
|---|---|
| Limited visibility | Relevance, product information completeness and search demand |
| Impressions but few clicks | Title clarity, main image and appeal compared with competing offers |
| Clicks but few purchases | Price, delivery, specifications, description and customer confidence |
| Sales without satisfactory profit | Fees, fulfilment costs, returns, advertising spend and selling price |
These are diagnostic starting points, not proof that one particular listing element caused the result.
Where possible, change one major element at a time and keep other conditions reasonably stable. If you simultaneously change the title, image, price and advertising budget, it becomes harder to determine which change mattered.
Also account for factors such as seasonal demand, stock availability and competitor activity.
Do not assume that a better listing will automatically produce a higher ranking or a particular percentage increase in sales. Use your own account data to determine whether the work is delivering results.

Frequently Asked Questions
How Do I Improve My Bol.com Product Ranking?
Start by ensuring that your product information is accurate, complete and relevant to the searches your customers make. Improve your title, attributes, images and description, and review the competitiveness of your offer. No single optimisation guarantees a particular position in search results.
Do More Keywords in a Bol.com Title Improve Visibility?
Not necessarily. Bol.com recommends using relevant terms without overloading the title. A clear title with the right product information is more useful than a repetitive string of keywords.
How Many Images Should a Bol.com Listing Have?
Use enough relevant images to help customers understand the product, its features and what is included. The appropriate number depends on the product and category. Follow Bol.com's image requirements and make every image serve a purpose.
Why Is My Bol.com Product Getting Clicks but Not Sales?
The problem may be the price, delivery expectations, unclear specifications, missing information, image quality or a mismatch between the shopper's expectations and the product. Review the listing alongside your overall offer before deciding what to change.
Can I Optimise Bol.com Listings for Google as Well?
Complete, accurate product information can help products become more visible in external search engines, including Google, according to Bol.com's product information guidance. However, marketplace optimisation and Google's organic search results are different systems, and neither guarantees rankings.
Should I Optimise Listings Myself or Hire a Specialist?
If you manage a small number of products, you can often begin with a structured checklist and work through the most important improvements yourself.
Professional support may be useful when you manage many SKUs, have limited time, need consistent product copy across a catalogue or want help identifying gaps in your existing listings.
