Don't publish on Allegro until every box is checked. This interactive checklist covers title rules, image specs, EAN codes, GPSR compliance, and everything else Allegro requires for a successful listing.
Your Allegro title is the first thing buyers see in search results. Getting it right directly impacts click-through rate and search visibility.
Allegro enforces a 75-character limit. Titles exceeding this are truncated in search results.
Place the brand name first for branded products. Allegro uses brand for filtering and matching.
Use the most searched Polish terms for your product. Avoid English unless the brand name requires it.
Include differentiating attributes so buyers can identify the exact variant from search results.
Allegro penalizes titles with excessive keywords, ALL CAPS, or special symbols like ★ or !!!.
Use standard sentence or title case. All-caps titles are flagged and can reduce listing quality score.
Allegro is Poland's largest online marketplace with over 22 million active buyers. Getting your listing right before hitting "publish" is critical because Allegro's algorithm rewards complete, well-optimized listings with higher search positions. Listings with missing attributes, poor images, or incorrect pricing get buried in search results and generate fewer sales.
This checklist covers every requirement Allegro enforces for product listings as of March 2026. Unlike generic listing advice, each item here corresponds to a specific Allegro validation rule or best practice that directly impacts your listing's performance. We've organized requirements into eight categories that mirror the listing creation flow in Allegro's seller panel.
Allegro uses a listing quality score that factors in title completeness, image quality, attribute coverage, and compliance data. Sellers with high-quality listings report up to 40% more visibility in search results compared to listings that only meet minimum requirements. The difference between a "complete" listing and an "optimized" listing can mean thousands of PLN in monthly revenue.
Key factors that Allegro's algorithm weighs most heavily include: title relevance to search queries, number and quality of images, completeness of required and optional attributes, competitive pricing, and shipping speed. Allegro Smart! eligibility is particularly important — listings eligible for Smart! delivery appear higher in filtered search results, and a large portion of Allegro buyers use the Smart! filter exclusively.
Since July 2024, the EU General Product Safety Regulation requires all sellers to provide product safety information including manufacturer details, EU responsible person (for non-EU manufacturers), CE marking documentation, and applicable safety warnings. Allegro has integrated dedicated GPSR fields into its listing creation process, and non-compliant listings face removal. This checklist includes all GPSR requirements specific to Allegro's implementation.
The most frequent listing errors on Allegro include: titles in English instead of Polish, images below 800x800 pixels, missing or incorrect EAN codes, prices displayed without VAT, and incomplete GPSR data. Each of these triggers either an automatic rejection or a listing quality penalty. Use this checklist to catch every issue before you publish.
Marqetir automatically formats titles, translates descriptions to Polish, maps categories, and ensures GPSR compliance for every listing you push to Allegro.
