Word count shouldn’t be an important factor in SEO content - rather the most important elements lie in the expertise & trust that is portrayed through the content & also the value to the user - so when creating content for the website we need to keep the user in mind & Google as a secondary thought.
Rather than focusing on a word count, focusing on signposting is a great way to ensure that Google understands your content & that it trusts you as an expert on the subject matter. Signposting can be done through a number of ways including implementation of key page headings, title tags & also descriptions as well as a strong internal navigation structure that allows Google to understand how your pages are semantically themed. This will allow Google to understand where & how it should rank your content.
