Hi there! I want to launch a site about a disease. Because I will be covering every symptom, treatment, medications etc. I was wondering from a seo perspective if it would be a good idea to have this structure: diseasetreatments/disease.com diseasesymptoms/disease.com diseasemedicine/disease.com etc. etc. And if so, how many subdomains would you say to be the max? And if I put adsense on them, could I still use subdomains? I hope you can help me. Thanks!
