How do I optimize my website content length for SEO marketing?

Make creating high-quality, user-friendly content your top priority. Focus on providing them with information that satisfies their needs and sheds light on their questions rather than worrying excessively about the word count. Take into account the preferred content types of your target audience. 
While some topics may require in-depth discussion, others may benefit from shorter, more targeted writing. Changing the length of your content is acceptable. Shorter, more concise articles may perform better than longer, more in-depth articles for some topics.
