I edited your code because it didn't work for me. I have used 2 AI to generate the new code with the ideas I have had. I think the next step could be to delete parameters for the categories. Brave does this by pressing the copy clean link button. https://www.amazon.es/gcx/Regalos-para-Hombres/gfhz/category?categoryId=adult-male I have also seen that you can also clean the nodes by leaving them like this https://www.amazon.com.be/b/node=27901539031 or like this https://www.amazon.com.be/b/?encoding=UTF8&node= 27901594031&bbn=27156491031&ref=Oct_d_odnav_d_27901539031_1
