What's a good average word length?

For most general-audience web content, an average word length of 4-5 characters indicates accessible, clear writing. Academic texts often average 6-7+ characters.

Does it count punctuation as part of word length?

No — punctuation attached to words (e.g., trailing periods or commas) is stripped before measuring letter count.

How does this relate to readability?

Average word length is a component of many readability formulas including Flesch Reading Ease. Shorter words contribute to higher (easier) readability scores.
