Optimising OnBuy product listings involves crafting clear titles, detailed descriptions, high-quality images and competitive pricing that align with how UK buyers search and decide. These elements directly influence ranking on the platform and conversion for early-stage e-commerce sellers.
By following structured approaches to each part of the listing, founders can improve discoverability without relying on paid promotion. This guide outlines specific, actionable methods grounded in how OnBuy surfaces products to shoppers across the UK.
Understanding OnBuy Ranking Factors
OnBuy uses a combination of relevance, performance and customer experience signals to determine search positions. Relevant titles and attributes help match buyer searches, while sales velocity, review quality and listing completeness affect ongoing visibility. Pricing competitiveness and image quality also play a part in click-through and conversion.
Start by ensuring every listing is complete with all mandatory attributes such as brand, category-specific fields and GTIN where applicable. Incomplete listings typically appear lower in results. Regularly review performance data available in the seller dashboard to identify which listings gain impressions but lack clicks or sales, then adjust accordingly.
Crafting Effective Product Titles
OnBuy titles should be concise, descriptive and contain the most important search terms near the beginning. Aim for 60-80 characters to avoid truncation in search results while including key information such as brand, product type, size, colour and main feature.
- Place the primary keyword or product name first, followed by distinguishing attributes.
- Avoid keyword stuffing or repetition of terms.
- Use natural UK English spelling and terminology that matches how customers search.
Example: instead of "Wireless Headphones Noise Cancelling Bluetooth Earphones Black", write "Sony WH-1000XM5 Wireless Noise Cancelling Headphones - Black". This structure improves relevance matching and helps buyers quickly understand the product. Test variations by monitoring search term reports in the seller account and refine titles that underperform.
Writing Compelling Descriptions
Descriptions on OnBuy allow up to 2000 characters and should provide clear, factual information that addresses common buyer questions. Structure the content with short paragraphs and bullet points for readability on mobile and desktop.
Begin with a one-sentence overview of the product, then cover key features, specifications, materials, usage instructions and care information. Include details that differentiate the item from similar products, such as exact dimensions, compatibility or included accessories. Use plain language rather than marketing slogans. For example, list battery life in hours, weight in grams and warranty length in months so buyers can compare easily. Update descriptions based on questions received through OnBuy messaging to reduce future enquiries and improve conversion.
Selecting and Optimising Images
High-quality images are essential for OnBuy listings because they drive click-through rates and reduce returns. Provide at least five images per product, with the first being a clean, well-lit main shot on a plain background showing the item from a direct front angle.
- Use additional images from multiple angles, in use, showing scale and highlighting details or features.
- Ensure images are at least 1000 pixels on the longest side and saved as JPEG or PNG with minimal compression.
- Include lifestyle or context shots where relevant, but avoid watermarks, text overlays or promotional banners.
Consistent lighting and sharp focus across the set help convey professionalism. For apparel or fashion items, show the product worn by models in neutral poses. Review the listing in both grid and detailed views to confirm images display clearly at thumbnail size.
Setting Competitive Pricing
Pricing on OnBuy must balance competitiveness with sustainable margins. Research similar products in the same category to understand the current price range, then position your offer based on value rather than being the absolute cheapest. Factors such as shipping speed, bundle options and seller performance can support slightly higher prices.
Consider using OnBuy's pricing tools to monitor competitors and adjust dynamically where appropriate. Clearly display any bulk or multi-buy discounts in the listing. Factor in all costs including fulfilment, packaging and platform charges before setting the final price. Because fees and thresholds can change, regularly check the current seller terms on OnBuy and cross-reference with GOV.UK or HMRC guidance on business taxation where relevant. Test price points on a small number of listings and track sales volume changes over several weeks.
Additional Listing Best Practices
Beyond core elements, optimise attributes such as bullet points, variation options (size, colour, pack quantity) and delivery settings. Accurate stock levels prevent order cancellations that harm seller ratings. Enable all relevant shipping options including next-day where possible, as delivery expectations influence buyer choice on OnBuy.
Encourage genuine reviews by fulfilling orders promptly and including a polite request for feedback where permitted by platform rules. Respond to messages within 24 hours to maintain high service metrics. Monitor listing health indicators in the seller dashboard and address any warnings promptly. For multichannel sellers, ensure OnBuy listings align with those on other platforms to avoid pricing or description conflicts that confuse buyers.
Reviewing and Iterating Performance
Optimisation is ongoing. Use OnBuy's reporting features to analyse search impressions, click rates, conversion and return reasons. Identify patterns such as high impressions but low clicks, which often indicate weak titles or images, or good clicks but low sales, which may point to pricing or description gaps.
Make one change at a time to measure impact, such as updating images first or revising titles for top-performing keywords. Keep records of changes and results to build an internal reference for future listings. For UK early-stage founders balancing multiple platforms, prioritise OnBuy listings that show the strongest organic growth potential before investing significant time in slower performers.
Frequently asked questions
