I’ve been blogging for about 6 months now I just recently posted my 50th blog post. It took awhile to figure out exactly what topic I was passionate enough about, originally I began as a food blogger, however I has since transitioned into a blog that aims to reach millenials who are at different stages including college, jobs, and new parenthood depending on the path they have chosen to take. Blogging helped me to get my freelance writing career off the ground, and I am hoping that soon I will be able to do well enough with my freelance writing that I can finally invest that ~$200 necessary to get my blog on the profit making path.
Unless you have a very good reason (unlikely), do not use the Plain or Numeric structure. They don’t play well with Google and other search engines because search engines use words, not numbers, to understand what your posts and pages are about. Search engines will be more likely to send people to your site when search words match the words in your permalinks.
