Commas

Avoid writing sentences with lots of commas.

Using a lot of commas can be a sign that you are writing sentences which are too long or too complicated. Shorten your sentences. 

Writing short sentences is one of the key features of effective web writing. People scan for information when reading on the web. Even highly literate people miss the meaning of longer sentences because they are scanning.

Research shows that the longer a sentence is, the less it is understood. The ideal sentence length for web writing is 15 to 20 words.

For example:

✘ This course is made up of research-informed teaching, where academics will work with you to develop your knowledge through a series of lectures, seminars and workshops

✔ This courses is made up of research-informed teaching. Academics will work with you to develop your knowledge. You will be taught through a series of lectures, seminars and workshops.
