Optimized for OnBuy's catalog-based search system and UK buyer search behavior (updated March 2026).
OnBuy is the UK's fastest-growing marketplace, competing directly with Amazon and eBay for UK shoppers. Unlike Amazon's complex A9 algorithm or eBay's Cassini engine, OnBuy uses a catalog-based system where products are identified by unique identifiers (EANs/barcodes) and multiple sellers can list against the same product. Your title is crucial for product discovery — it determines whether buyers find your listing when searching for products on the platform.
OnBuy works differently from eBay. Instead of each seller creating unique listings, OnBuy maintains a product catalog where sellers attach their offers to existing products. If your product is already in the catalog, your title matters less because you'll share the catalog listing's title. For new products, you create the catalog entry — and your title becomes the permanent product title that all future sellers will use. This means getting the title right on the first listing is critical for long-term visibility.
The best OnBuy titles follow the format: Brand + Product Type + Model + Key Spec + Color/Size. For example: "Dyson V15 Detect Cordless Vacuum Cleaner 60min Battery HEPA Filter Gold" is specific, searchable, and covers every term a UK buyer might use. Avoid promotional language ("BEST DEAL"), delivery information ("FREE NEXT DAY"), and excessive punctuation. OnBuy displays shipping and pricing details separately — keep your title focused on the product itself.
OnBuy serves UK buyers exclusively, so use British English spellings (colour, grey, aluminium) and UK sizing conventions. Include UK-specific attributes where relevant: UK plug type for electronics, UK dress sizes for clothing, and metric measurements. Reference UK standards and certifications (BSI, CE marking) when applicable. UK buyers searching on OnBuy are typically comparing against Amazon UK and eBay UK listings, so matching their search terminology is important.
The biggest mistakes sellers make on OnBuy are: using all caps (looks spammy), including promotional text that belongs in the description, duplicating keywords unnecessarily, using Amazon-style keyword stuffing (OnBuy's system doesn't benefit from it), and omitting the brand name. Also avoid putting shipping or pricing information in the title — OnBuy shows this separately and having "FREE DELIVERY" in your title wastes valuable keyword space that could describe your product better.
