I've a good tech blog with about 10k to 15k organic searches per month. I write with another guy about good content articles on tech niche like apple, android etc and games too I'd ask you if it's good to make a subdomain like this: games.mydomain.com and have the main website "mydomain.com" as home page/main Brand (blog logo). I write in this blog about various tech articles and I think subdomains can help me to keep the blog posts organized. Can subdomains harm SEO of my blog? If subdomains aren't good, is better then to use a section only for articles? Example: mydomain.com/games Thanks in advance.
