When it does matter: If the bounce rate of a particular page on a website is higher than the average rate of that website, it indicates that visitors are not staying and engaging with the page, which means they are leaving the website quickly. This could indicate that the page doesn't offer the information the visitor was looking for and that the page might need to be improved.
When it doesn't matter: If a website's overall bounce rate is below average, a high bounce rate on a particular page does not necessarily indicate any issue with that page. For example, on a contact us page, a high bounce rate is expected since visitors usually choose contact pages to find information and don't need to stay on the page any longer.
