There is no age limit to blogging. One more thing to remember is to update your blog regularly. It should always be fresh or have new content.

First and foremost keep your readers in mind. If you want people to keep coming back you need to make it easy to read and understand. Remember that in this day and age people using the internet will often spend a lot of time just skimming over pages so you need to capture and then keep their interest, the best way to do this is to keep your writing clear and concise, while it doesn’t need to be grammatically ideal (at least for a personal blog) it should at least make sense.

Also, where possible, keep your individual posts in related categories etc. that makes it a lot easier for first time and casual readers to find what it is they may be looking for.
