Online auctions knowledge base

What this knowledge base covers

The e-Bids knowledge base collects editorial articles on online auctions in the Netherlands: bidding strategy, premiums and buyer costs, safe payment, foreclosure auctions, platform choice, and categories such as art, cars, household goods and domains. Each article has a named byline, internal links to related pieces, and where relevant a Sources list with official pages we recently checked.

This is not an encyclopaedia of every auction house worldwide and not a live lot feed. It is a guide that helps you understand your risk before you bid, which costs sit on top of the hammer price, and which platform type fits your object. After reading, open the auction finder for a deeplink to the official platform, or a comparison page if you are choosing between two houses.

How to use this hub

Start with the category filters below if you already know whether you need strategy, costs, property or a specific platform. If not, read a broad piece on premiums or safe payment first, then go deeper by category or house. Articles cross-link: strategy without cost literacy is half the job; foreclosure without plok context too.

Category hubs carry longer intro texts with FAQ and Sources. Article pages carry depth in the body, with facts that carry an access date. Platform fee changes are updated after research; we do not bump dates without substance.

Editorial boundaries

We write from the Dutch bidder's perspective, focusing on private buyers unless an article is explicitly B2B (for example vehicle auctions via OPENLANE). We do not invent lot counts, guaranteed returns or closing prices. Affiliate disclosure must be visible when Catawiki links can earn commission; other referrals stay editorial.

Legal or dispute questions about a concrete lot belong with the platform or independent consumer guidance, not with our desk as customer support. We do correct errors in our copy quickly when you report them via contact.

Themes that keep returning

Buyer's premiums differ sharply by house: curated platforms often charge a lower percentage plus a fixed fee; traditional art houses often charge a higher percentage. Foreclosure auctions add plok, notary fees and sometimes clearance. Industrial and insolvency auctions turn on pickup windows and as-is condition. Domain auctions need valuation discipline without hype. Cars need a private-versus-dealer distinction.

Those themes recur across articles because bidders combine them in practice: your maximum bid only works if you know premium and transport. Use filters and related links to build that combination instead of treating one article as a complete manual.

From reading to bidding

A solid path: (1) read the article for your category or risk, (2) check Sources on the platform itself, (3) open the auction finder for the right starting point, (4) register only on official channels with recognisable payment flows, (5) write your all-in maximum before the clock. Adrenaline is expensive; preparation is dull and effective.

Categories versus single articles

Category hubs bundle introduction, deeper body copy, FAQ and Sources around one theme so you do not have to guess which standalone article comes first. Single articles go deeper on one question: a fee, a platform ritual, or a concrete risk such as paying after a winning bid. Use the hub as a map and the article as execution detail. Cross-links between both are intentional; follow them when you still miss a cost line or pickup rule.

What we measure as quality

We check whether a piece answers a real bidder question, whether sources are verifiable, and whether we invent live prices or lot counts nowhere. Dead links or stale percentages are corrected after a tip or a periodic check. The article list below is hand-curated and grows by editorial priority, not AI bulk. Missing a topic? Tip the desk: good knowledge bases stay alive through reader questions.
