“Dwell time” is the amount of time visitors spend on your website and it can affect SEO ranking.
When you provide useful content, visitors tend to stay longer on your website to consume the information and therefore increase the dwell time.
Based on this research, content between 2,000 – 2,500 words seems to rank the highest in search engine results.
Although word count doesn’t rule the SEO world – nobody will read your stuff if it’s not helpful to them – longer content does give you the opportunity to provide more value, include more keywords, incorporate more outbound links, and of course, get people to spend more time reading to increase dwell time.
Another reason to create highly useful content is that when visitors bookmark your content on Chrome, it will improve SEO ranking of your website in Google.
