Write for an audience that scans when they read.
-lists are great
-use multiple sub-headings
-add a few pics for eye-candy
-write 3 sentence paragraphs, tops
-line breaks between paragraphs
-call to action at the end of every article - what should the reader do next
Bottom line - your article needs to be conversational. Read it out loud before submitting the final copy. If you wouldn't say it like that, don't write it like that.
And include your personality - make it entertaining
P.S. I wouldn't use many semicolons or commas - dashes ("-") keep the reader scanning and not pausing for too long at any one point
