Neil Patel reported a while back;
Content really is king The average content length for a web page that ranks in the top 10 results for any keyword on Google has at least 2,000 words. The higher up you go on the search listings page, the more content each web page has. Google always prefers content rich sites. The interesting part is that Google doesn’t prefer more content because it feels it is more valuable. It actually prefers content rich sites.
