Generally speaking, high-traffic websites are viewed as being more likely to rank higher in search engine results pages (SEOs). However, there is no hard and fast rule for determining what constitutes high-traffic websites, as this largely depends on the nature of the specific website in question.
Some suggestions for determining if a website is high traffic include looking at the number of unique website visitors that the website receives each day, the number of page views that the website receives each day, and the number of times that people are likely to typically access the website each day.
If these numbers indicate that the website is likely to be viewed by a large number of people each day, then it is likely to be viewed as high traffic. From this context, a website with more than 10,000 visitors per month or more than 10,000 page views per month would be good enough [to say] to count as a high-traffic website in SEO.
