I am finding it difficult to decide whether having small blog sites under specific domains is better than having one blog site that contains several sections about the subcategories of the main topic.
Let's say I am expert in cooking and want to write cooking lessons. I could buy some domains such as cookingdesserts.com, makejuices.com, veggiecooking.com and write about those specific subtopics which all relate to cooking.
Or is it better to find a domain that describes all those subtopics. For instance, cookingtutorials.com (assuming it is free) and then have menu items for each subtopic. If the user clicks on "Desserts" they are shown the blog articles about desserts.
It seems complicated to me to think and decide which method to use. I would appreciate knowing the pros and cons of each of the options.
