I’ve been keeping an English blog for many years. These practical tips have helped me over the course of my blogging.

● Read quality books, blogs, journals, etc. which are written in English. Blogging is not always about writing. 【1】 Reading also improves your English comprehension, grammar, spelling, vocabulary and writing.

● Practice helps, so continue writing. 【2】 Trying to make a perfect post （帖子） free from grammar and spelling mistakes is good but you’re not making use of your time efficiently.

● 【3】 Think about the main points you want to raise. I prepare an outline of my post and a list of the points I want to talk about. Doing this has helped me stay on track and focus on my main points. The outline and the list of points I want to write about serve as my guidelines when I’m writing.

● When writing, use simple words and sentences. Using simple sentences makes your job as a blogger easier. 【4】 Always remember this: The aim of your writing is to get your message across and the only way to become an effective writer is successfully conveying your message to your readers.

● Write your posts ahead of time. 【5】 To free yourself from the pressure of making a post on daily basis, which might affect your writing, consider making your posts ahead of time.

A. Also, it makes your posts more understandable to your readers.

B. Welcome comments from your blog reaers.

C. There are benefits of daily blogging but if it becomes tiring, forget about it.
