My top competitor for a certain niche has about 30k of unique content.. My team has just finished writing our content and we have 30k + unique content now too.. The issue I'm facing is how format the site in the best way.. My competitor has his articles under 4 main categories so the menu only has 4 options. When you click on a category it takes you to another page which has a list of all the articles from that category that you can read.. At the moment on my site I just have a list of all the articles in the menu on the side.. I think for user experience both options are easy to navigate however I want to go for what ever Google prefers.. What would you suggest? Main categories which take you to another page where you choose the article you want to read OR all the articles listed on the side of the site one after another?
