It’s important to provide unique content. If possible also try to blog for an unsaturated niche. You could use google to search for saturated niches. Web hosting for example is a very saturated niche, there are countless blogs and websites about web hosting so It’s recommended you do not put any effort into blogging about it. The more websites and blogs that rank for a certain keyword the harder it will be for you to get traffic. It’s all about being creative! copying work is not done, taking pieces from other people’s work and rewriting it however, is a good way to provide unique and valuable content. I understand that this blog itself will be very hard to promote, since there are thousands of sites that give blogging tips. I’m trying to give a lot of unique content. I’m sure it will work out sooner or later!
