Bidding Fox

What the extension can do

Bidding Fox is an intelligent bidding automation tool that manages your ads on Heureka and Zboží.cz and adjusts click prices several times a day based on current data. It recognizes products with the highest sales potential and secures them top positions, while limiting ads for non-selling items so you don’t waste money.

It lets you set a maximum PNO and how to react when the limit is reached, define maximum CPC, monitor your competitors’ prices, and if desired, adjust your bidding accordingly. You can also choose not to bid on items that rank at certain positions in search results, for example from the 5th position and lower.

Key features

• Continuous automatic bidding – Bidding Fox analyzes the sales potential of products and dynamically manages their ads to maximize visibility. For items with low potential, it reduces advertising to save your credit. Bids are adjusted several times a day using the latest data verified directly on Heureka and Zboží.cz.
• Custom strategies – Segment your assortment by margin, price, or category and set target PNO, CPC, and desired positions for each segment. You can also schedule strategies for seasonal events (e.g., Black Friday).
• Cost savings – With the feature “Do not bid when I’m in the top position with Heureka Cart,” you avoid unnecessary clicks. The extension also automatically lowers CPC once a product reaches its set goal. You can also assign a limited budget for a chosen period for any strategy.
• Diagnostics and alerts – Bidding Fox detects ad issues (e.g., tracking outages), sends you alerts by email or into Mergado, and recommends improvements. You can also configure what exactly you want to monitor, keeping control over the development of products that matter most to you.
• Competitor monitoring – Gain detailed insight into product and shipping prices, positions on product cards, and availability. Find out who sells the same products as you and at what price.
• Reports for you and your clients – Always have clear charts and performance statistics at hand. Receive regular performance and comparison reports in PDF, or download them in CSV, HTML, or XLSX.
