The attention span of a goldfish is 9 seconds.
The attention span of an adult human is 8.25 seconds.
That is according to a study conducted in 2015.
In 2000, the average human adult had an attention span of 12 seconds. (Source)
That is a huge decrease in attention span.
This means we need to be able to communicate FAST!
That also could mean a goldfish is more engaged with your website than the average human.
Unless of course, you built your website to capture attention.
