The NUMBER ONE RULE when writing content.

Gee, it’s so simple: put your content into spellcheck.
Last week I got three emails (the same email, three times) from an organization that is trying to get me to attend one of its events. The keynote speaker is from Australia. The word “Australia” was misspelled once, twice, three times!
How does that happen? How can an organization with any claim to professionalism misspell “Australia”?
It wasn’t surprising to me when I found that a quick look at the website promoting the event showed numerous misspellings, punctuation and grammar errors, and just plain sloppy writing.
Moral of the story: use spellcheck. Spellcheck will help you identify many of the common writing problems, though not, of course, all of them. That’s your job!
