Is Website Traffic Help in Google Ranking?

Website traffic, in itself, is not a direct ranking factor with Google. However, high website traffic indicates that the site has good content that people are likely to click on.

This implies that higher website traffic will lead to better conversions and more clicks on the paid search ads served alongside the organic results for this page.

It can be helpful, but having no search engine traffic will make it look suspicious. So you have to combine them.
