I just started a new blog a couple days ago but not sure if I should blog everything that I want to blog or should I keep the whole thing oriented to one topic. For example, should I blog only about technology, or sports, or news, internet - or I can put whatever I feel like (using wordpress - everything is categorized) looking for ur help
It depends who you are blogging for. If you are blogging for readers with the aim of making money further down the line you'll want to just choose one of the above topics. Although news could be combined with all of them. I run a sports blog and include news articles in it. Mixing all four up will be too general and you'll struggle to get enough content online and you won't get many readers who are interested in all of the above.
