How important is it to follow grammar rules and syntax in your microscopy? Avoid misspellings like adress, buisness, or garantee and basic mistakes like your/you're, they're/their, or then/than because they create a bad impression.

Users may assume you're too lazy to spell-check your copy and don't care enough about your product. This makes your business look extremely unprofessional and causes users to distrust your product and eventually leave.

However, it's possible to bend debatable grammar conventions — as long as it's consistent and fits your brand voice. Examples of such conventions include:

• Not ending the sentence with a preposition ("Tell us where you come from")
• Splitting infinitives ("To boldly go where no man has gone before")
• Using passive voice ("Your account has been updated")

As for syntax, the shorter the sentences are, the better. Avoid overusing complex sentences with multiple subordinate clauses or long compound sentences.
