high pagerank generate more traffic

the most easy way to explain why high pagerank can generate more web traffic is, the higher your website pagerank is, then the higher Google is likely to list your website in the search engine result pages. This is because the more other webiste link to yours, then the more relevent your web page must be to the topic in hand, otherwise they wouldn't link to you.

The higher your Page Rank, then the more people will want you to link to their website. They will offer you a reciprocal link if you want to trade link with him/her, and that will increase your pagerank. Besides that, they too will visit your website since your website has a high pagerank, and this will increase your web traffic.

A high Page Rank shows that you have a high number of links on the pages of other websites. There is then the possibility of others clicking on these links to get to your website.
