Facebook has ceded its long-held second position among the top websites in the US to YouTube, according to a new study.
This is owing to severe decline in monthly page visits of Facebook, from 8.5 billion to 4.7 billion in the last two years.
Although Facebook's app traffic has grown, it is not enough to make up for that loss, CNBC reported on Wednesday citing the study by market research firm SimilarWeb.
The five websites receiving the most traffic in the U.S. in the last several years have been Google, YouTube, Facebook, Yahoo and Amazon, in that order.
Facebook earlier reported that in the second quarter of this year, its number of daily active users remained flat in North America and went down in Europe.
Owned by Google parent Alphabet, YouTube, on the other hand, has seen increased traffic and rise in viewership, said the study that found Google's position as the biggest website in the US remaining unshaken.
