How to minimize such risk:
carefully approach the choice of goods that you are going to sell on the marketplace (any), and focus not on mass production, but on the uniqueness of the product;
track competing products (you can filter them by brand or some unique characteristics) and contact technical support if you detect the slightest violations;
take care of the issue of copyright protection.
After all, if the seller cannot prove that the product sold by the competitor violates his rights, then the Price Index will continue to deteriorate, the product will continue to decrease in the search results, and there will be fewer and fewer orders.
Unfortunately, for example, Ozon does not require sri lanka consumer email list confirmation of brand ownership : any seller can easily register on the marketplace, sell goods under an existing brand, and also borrow images from competitors and a description of the goods.
We also encountered similar “borrowing” in practice with one of our Clients: a seller from China used all of our content without a second thought.
Contacting Ozon technical support did not help: specialists asked for source files (in our case, texts and infographics), as well as documents confirming copyright. If there is no such confirmation, then there is no way to "eliminate" the competitor's card.
How to reduce the risks of copying content:
prepare the most unique content;
save the source files of all files and think through all the options available in your case for confirming copyright;
Monitor competitors' products for specific features and don't hesitate to contact technical support if you discover a plagiarism.
In the long term, with such input data, the situation “I bought goods for 100 thousand rubles and sold them quickly for 300 thousand” becomes practically impossible.
However, let's be objective: unfair competition and the use of other people's content existed and exist even without the intervention of foreign sellers. The only difference is in the legal protection of the participants in the process.
