The invisible score determining your Bol.com visibility
When you search for a product on Bol.com and your listing doesn't appear — even though you have the right keywords and a competitive price — the culprit is usually not your marketing budget. It's your listing health.
Bol.com internally evaluates every product listing on a set of quality criteria. Listings that meet these criteria get better placement, appear in filtered searches, and are eligible for the Buy Box. Listings that fall short get pushed down — sometimes invisibly, without any explicit warning.
A listing health check is the process of systematically evaluating your listing against these criteria and fixing what's broken.
What a listing health check actually measures
1. Information completeness
Every Bol.com product category has a set of attributes — some required, some recommended. Required attributes are the minimum threshold. Recommended attributes are what separate high-health listings from average ones.
Incomplete attribute coverage has a direct effect on filter visibility. When a buyer filters by "color: black" or "material: stainless steel" — Bol.com matches against attribute fields, not text content. If your product is black but the color attribute isn't filled in, you're invisible to every filtered search for black products in your category.
2. Title quality
A health check evaluates your title for:
- Primary keyword placement — is it in the first 25 characters?
- Prohibited characters — exclamation marks, star ratings, all-caps words, and promotional claims violate Bol.com's guidelines
- Length — too short signals thin content; too long gets cut off in search results
- Category relevance — does the title match what buyers in this category actually search for?
3. Image coverage and quality
The minimum is one white-background product photo. But listings with 3+ high-quality images consistently outperform those with only one — both in algorithmic placement and conversion.
A health check flags:
- Images below 1000×1000 pixels (disables zoom functionality)
- Watermarks or text overlays on the main image
- Missing product detail or lifestyle shots
4. Description quality
Thin descriptions (under 200 words) or descriptions that simply repeat the title are a health signal. Bol.com wants buyers to have enough information to make a confident purchase decision without leaving the page. A complete description reduces returns and increases post-purchase satisfaction — both metrics Bol.com measures.
5. EAN and catalog data accuracy
An incorrect or missing EAN causes catalog matching errors and can result in your listing being merged with or duplicated against a different product. A health check catches mismatches between your product data and Bol.com's catalog.
6. Seller performance signals
While these aren't part of the listing itself, they influence listing health and visibility:
- Return rate (high return rate = listing may be misleading)
- Cancellation rate
- Delivery performance
The real cost of ignoring listing health
Let's make this concrete. Consider two identical products:
Product A: All attributes filled, optimized title, 5 images, 300-word description Product B: 40% of attributes filled, generic title, 1 image, 80-word description
Both products sell at the same price with the same number of reviews.
Product A will appear in significantly more filter matches, rank higher in organic search, and convert at a higher rate because buyers get better information. Product B will struggle to get impressions, lose filtered searches, and rely almost entirely on paid placement to get visibility.
The gap between these two listings doesn't cost much to close. It typically requires 2–4 hours of work. But most sellers never close it — because they don't know exactly what's missing.
How to run a listing health check on Lijstify
Lijstify's free health check tool analyses your Bol.com listing across 14 specific factors and generates a prioritized action list.
How it works:
- Enter your Bol.com product URL
- Lijstify fetches and analyses your listing data
- You receive a structured report showing what's complete, what's missing, and what to fix first
The report covers: title score, attribute completeness by category, image count and quality signals, description length and structure, and keyword coverage.
It takes 60 seconds and is free. No account required for the basic check.
The most common health check findings
After analysing thousands of Bol.com listings, the most frequent issues are:
1. Missing category attributes (78% of listings) Most sellers fill the required attributes but leave recommended attributes blank. These recommended fields are exactly what drives filter visibility.
2. Title length issues (61% of listings) Either too short (under 50 characters, leaving keyword opportunities unused) or too long (over 120 characters, getting cut off in mobile search results).
3. Fewer than 3 images (54% of listings) One main photo is not enough. Buyers use the image gallery to assess quality before buying — and more images mean higher engagement and lower bounce rate.
4. Thin description (49% of listings) Descriptions under 150 words. This leaves buyers with unanswered questions and signals to Bol.com that the listing is low-effort.
5. Wrong primary keyword placement (44% of listings) The main product keyword appears in the middle or end of the title rather than the beginning. This is a significant algorithmic disadvantage.
Fixing health issues: where to start
If a health check reveals multiple issues, prioritize in this order:
- Category attributes — highest impact on filter visibility, usually fastest to fix
- Title — highest algorithmic weight, affects impressions directly
- Images — affects both health score and conversion rate
- Description — affects conversion and post-purchase satisfaction
Avoid trying to fix everything at once. Make one or two changes at a time, wait 72 hours for Bol.com to re-index, and track the impact on impressions before moving to the next fix.
Health check vs. full listing optimization
A health check diagnoses structural problems. Full listing optimization — rewriting titles, generating new bullet points, improving descriptions based on competitor analysis — goes further.
For sellers who are just getting started or troubleshooting a specific listing, the health check is the right first step. It tells you whether you have foundational problems that need fixing before anything else will work.
For sellers who want to actively improve rankings and conversion, the health check feeds into a broader optimization process. Lijstify combines both: the health check surfaces structural gaps, and the AI optimization tools help you close them efficiently.
