Overview

What is Vergelijk.nl Product Feed?

Vergelijk.nl is one of the Netherlands' long-standing price comparison platforms, operated by Compare Group, with strong positioning in consumer electronics, home appliances, and travel categories. Although smaller in raw volume than Beslist, Vergelijk.nl users skew slightly more affluent and tech-savvy and convert at notably higher rates in higher-AOV categories. For Dutch ecommerce merchants - especially those selling electronics, white goods, or photography equipment - it is one of the highest-ROI comparison channels per click.

Vergelijk.nl ingests product data through a CSV product feed (UTF-8, semicolon-delimited) hosted on a URL polled daily. The schema is Vergelijk-specific but maps cleanly to standard ecommerce data models. Required columns include id, title, description, brand, price (EUR VAT-included), delivery_time, delivery_cost, stock, category, deeplink, and image_url. Vergelijk also strongly prefers EAN/GTIN for cross-merchant comparison and exposes optional columns for promotions, warranty, and energy labels.

Vergelijk's commercial model is CPC: merchants pay per click sent to their storefront, with bid amounts configurable per category. Within categories, listings are ranked by a weighted combination of price competitiveness, delivery time, stock, and merchant rating. Vergelijk is more lenient than Beslist or Idealo about minor stock or price drift but compensates with stricter quality requirements on titles and descriptions - listings flagged as low-quality (keyword stuffing, duplicate descriptions across SKUs, all-caps titles) are demoted aggressively.

Feed Structure

How Vergelijk.nl Product Feed Feeds Are Structured

Key structural rules and formatting requirements for this feed type

  1. 1

    Use UTF-8 with semicolon delimiter and quoted fields

    Vergelijk.nl expects UTF-8 (preferably with BOM) and semicolon-separated columns. Quote any field containing the delimiter, newlines, or double-quote characters. Embedded double-quotes are escaped by doubling them (RFC 4180 style). Excel's default Save As CSV in NL locale produces semicolon files automatically, which is convenient but produces Windows-1252 encoding by default - always specify UTF-8.

    id;title;description;brand;price;delivery_time;...
    "SKU-001";"Nike Air Max 90 - Hardloopschoen, ""special edition""";"...";"Nike";"149.95"
  2. 2

    Submit prices in EUR with VAT included

    Vergelijk.nl requires gross prices (BTW included). Use a period (.) as the decimal separator: 149.95, not 149,95. Currency symbol must be omitted. The price is cross-checked against the deeplink landing page on each refresh - mismatches trigger 24-to-48-hour suppression. Same rule applies to delivery_cost.

    price: 149.95
    delivery_cost: 5.95
  3. 3

    Use parseable delivery_time formats

    Vergelijk parses delivery_time numerically for ranking and filtering. Use formats like 1 werkdag, 1-2 werkdagen, 2-4 werkdagen, 1-2 weken. Free-form text (Snel beschikbaar, Direct uit voorraad) cannot be parsed and the listing is treated as having an unknown delivery time, pushing it to the bottom of the comparison.

    delivery_time: 1 werkdag
    delivery_time: 1-2 werkdagen
  4. 4

    Use category paths with > separators

    Vergelijk accepts free-form category paths with > separators or its own taxonomy strings (downloadable from the merchant portal). Auto-mapping covers ~80 percent of free-form paths but Vergelijk's taxonomy strings produce the most precise category-page placement. Update mappings annually because the taxonomy is revised periodically.

    Mode > Schoenen > Sportschoenen > Hardloopschoenen
  5. 5

    Express stock as integer count, not boolean

    stock is a unit count. 0 suppresses the listing; 1+ keeps it active. Stock count is also used as a minor ranking input - higher stock outranks lower stock when other factors tie - so do not pad with artificial 999 values. Use realistic counts; if your system tracks only in_stock vs out_of_stock, use 10 as a default for in-stock items.

    stock: 12
    stock: 0 <!-- suppressed -->
  6. 6

    Include EAN whenever possible

    Vergelijk uses EAN for cross-merchant matching. Listings without EAN appear only on standalone product pages, missing the side-by-side comparison views where most clicks happen. Aim for 90+ percent EAN coverage on branded SKUs. For private-label products without GTIN, leave the field empty rather than inventing codes.

Optimization

Vergelijk.nl Product Feed Optimization Tips

Proven strategies to improve your feed performance and product visibility

  1. 1

    Write titles in clear Dutch with sentence-case capitalization

    Vergelijk.nl&apos;s low-quality detector flags ALL-CAPS titles and titles with excessive special-character usage (asterisks, exclamation marks, emoji). Use sentence case or title case in clean Dutch. Lead with brand, then product name, then key attributes (gender, color, size).

    Goed: Nike Air Max 90 Heren Hardloopschoen Zwart Maat 42
    Slecht: NIKE AIR MAX 90!! ★ HARDLOOPSCHOEN ★ ZWART
  2. 2

    Avoid duplicate descriptions across SKUs

    Vergelijk&apos;s quality detector flags catalogs where 30+ percent of products share identical description text - common when descriptions are generated from category templates. Even small per-SKU customization (mentioning the specific color, size, or model variant in the description) clears the flag and improves placement. The fix is usually a one-line change in your product data export to splice variant attributes into the description template.

    Generic (avoid): De Nike Air Max 90 is een populaire sneaker.
    Specific (better): De Nike Air Max 90 in zwart, maat 42, met klassieke Max Air-demping.
  3. 3

    Pursue any Compare Group merchant verification programs available to your account

    Compare Group runs merchant trust signals across its comparison properties; the specific program names and eligibility rules vary by locale and are configured in the merchant portal rather than published as a uniform spec. Confirm with your account manager which trust certifications are available, and the eligibility thresholds (typically: clean activity tenure, low dispute rate, strong delivery ratings, and a published return policy of 14+ days). Trust badges on listings consistently lift CTR by 8 to 12 percent in this category of platforms.

    Generic prerequisites: clean tenure, low disputes, strong delivery ratings, 14+ day returns
  4. 4

    Surface energy labels and warranty terms in higher-AOV categories

    Vergelijk users in electronics and white goods categories actively filter on energy_label and warranty. Listings with declared values receive 10 to 20 percent higher CTR in those categories. Pull the data from your product database (often already tracked for compliance) and plumb it through to the Vergelijk feed.

    energy_label: A++
    warranty: 2 jaar fabrieksgarantie
  5. 5

    Refresh feed daily, twice during peak windows

    Vergelijk polls daily by default. During Q4 and major promo windows, schedule twice-daily fetches at 06:00 and 14:00 CET to catch warehouse and promo updates before competitors. Stale prices during high-demand periods cost more in lost rank than the engineering effort of more frequent refreshes.

    Off-peak: daily 03:00 CET
    Peak: twice daily 06:00 + 14:00
  6. 6

    Configure CPC per category reflecting margin and AOV

    Set CPC bids in the merchant portal per category. Higher-AOV categories can sustain higher CPCs because absolute margin per click is larger; thin-margin categories need conservative bids. The Vergelijk audience converts well in electronics/white-goods/travel - those categories often warrant CPCs 50-80 percent higher than the platform default.

    Witgoed CPC: 0.55
    Tuinmeubels CPC: 0.20
Troubleshooting

Common Vergelijk.nl Product Feed Feed Errors

Frequent feed issues and how to resolve them

  • Error

    Price mismatch with landing page

    Solution

    Vergelijk verifies the deeplink price on every refresh. Differences greater than 0.01 EUR trigger 24-to-48-hour suppression. Diagnose via the Issues tab in the merchant portal. Most causes trace to timezone-mismatched promo windows or feed cache; fix at the source.

  • Error

    Encoding error on Dutch characters

    Solution

    Vergelijk requires UTF-8 (preferably with BOM). Excel-default Windows-1252 produces corrupted accented characters (é -> é). Use a programmatic export (Python, Node) and explicitly set UTF-8 with BOM. Verify the first three bytes are EF BB BF.

  • Error

    Duplicate description quality flag

    Solution

    Catalogs with 30+ percent identical descriptions across SKUs are flagged as low quality and demoted. Splice variant attributes (color, size, model) into the description template at export time. Even a single varied sentence per SKU clears the flag.

  • Error

    Delivery_time not parseable

    Solution

    Free-form text like Snel beschikbaar cannot be parsed. Use parseable formats: 1 werkdag, 1-2 werkdagen, 2-4 werkdagen, 1-2 weken.

  • Error

    Image fetch failures

    Solution

    Vergelijk&apos;s crawler uses VergelijkBot. Whitelist VergelijkBot in robots.txt and CDN bot rules. Verify with curl -A 'VergelijkBot' from outside your office network.

  • Error

    Category fallback to generic node

    Solution

    Free-form categories that don&apos;t auto-map fall back to a generic node and lose category-page placement. Download the latest taxonomy from the merchant portal and map explicitly. Schedule annual review.

Metrics

Feed Performance Metrics to Track

Key metrics that indicate how well your product feed is performing

  • Click-Through Rate (CTR)

    Vergelijk CTR averages 2 to 3.5 percent for non-top-3 listings, 7 to 12 percent for top-3 positions. Below 1.5 percent typically indicates a weak product image or pricing more than 8 percent above the lowest competitor on the same EAN.

  • Average Position

    Average rank in category and search-results pages, segmented by category. Top-3 captures 55 to 65 percent of clicks. Position is determined by price, delivery_time, stock, merchant rating, and CPC bid (above the category minimum).

  • Conversion Rate

    Percentage of click-throughs completing a purchase. Vergelijk traffic typically converts at 4 to 7 percent across categories - higher than search traffic because users are deep in consideration. Below 2.5 percent points to a landing-page issue (slow load, mobile UX, missing trust signals).

  • Cost Per Acquisition (CPA)

    Total CPC spend divided by attributed orders. Healthy CPA: 5 to 12 EUR for fashion, 8 to 18 EUR for electronics, 12 to 25 EUR for high-AOV categories like white goods. Track per-category and adjust CPC bids to keep CPA below 30 percent of average order value.

  • Dispute Rate

    Percentage of orders resulting in Vergelijk-mediated disputes. Above 3 percent triggers ranking demotion; above 5 percent triggers manual review. Most disputes trace to declared-vs-actual delivery time mismatches.

How to Set Up Your Vergelijk.nl Product Feed Feed

Step-by-step guide to creating and optimizing your product feed

1

Register a Vergelijk.nl merchant account

Sign up through the Vergelijk Compare Group business portal. You will need a verified domain, a registered business entity (KvK), a published return policy, and a customer service contact. Approval typically takes 5 to 10 business days. New merchants enter a probationary tier; this lifts after 30 orders with dispute rate below 5 percent.

2

Generate the semicolon-delimited UTF-8 CSV

Build a UTF-8 (with BOM) CSV with semicolon delimiters. Include all 11 required columns plus EAN where available. Validate with the Vergelijk online validator before submission. Host on an HTTPS URL accessible without authentication.

3

Map categories to Vergelijk taxonomy

Download the latest taxonomy from the merchant portal. Map your internal categories to Vergelijk&apos;s categories, embedding the mapped strings in your category column. Auto-mapping handles ~80 percent of free-form paths but explicit mappings produce noticeably better category-page placement.
