Hi, I am a newbie and I made a blog with 2 mixed niches, "FITNESS AND TECHNOLOGY " it has over 70 posts. I understood my fault. How can I create a new blog and separate my niche safely. One blog for TECHNOLOGY and another blog for FITNESS ?? All are indexed by google. If I just delete some posts on my blog and publish it on my new blog, it will be bad or suspicious ?? Google will ban for duplicate content ?? Please give me advice.
