Frequently asked questions

Do watermarks affect SEO or image search rankings?

Watermarks do not directly affect your search rankings. However, they can indirectly help by preventing image theft — if competitors steal your images without watermarks, they may rank for the same image searches with your photography.

Can I add my logo as a watermark?

Yes. Upload your logo in PNG format with a transparent background for best results. The logo is overlaid on your product images with your chosen opacity, position and size.

Will watermarks prevent my images from being used on Amazon?

Amazon prohibits watermarks or logos on main product images. Additional product images may include watermarks. Watermark only your store images and keep clean versions for marketplace submissions.

What is the best position for a product image watermark?

The lower corners (bottom-right or bottom-left) are the industry standard for product watermarks. They are visible enough to deter theft without obscuring the main product.

What opacity should I use for my watermark?

40–60% opacity produces the most professional results. The watermark is clearly visible at this level without dominating the image.

Best practices voor watermerken in e-commerce

Positie: rechter of linker onderhoek

De onderste hoeken zijn de industriestandaard voor productwatermerken. Ze zijn zichtbaar genoeg om diefstal te ontmoedigen zonder het hoofdproduct te verbergen.

Dekking: 40–60% voor de juiste balans

Een half-transparant watermerk ziet er professioneler uit dan een volledig ondoorzichtig watermerk.

Grootte: 15–25% van beeldbreedte voor logo's

Het watermerk moet opvallen maar niet domineren. imgflow stelt de grootte in als percentage zodat het correct schaalt in alle afbeeldingen van de batch.
