Generally speaking, a low Bounce Rate means the site is doing well and a high Bounce rate means there could be an issue with your website’s design, usability, SEO/content, or functionality. Anything below a 10% bounce rate must not be ignored, this could be a technical issue in the website or settings that need to be worked on. This is especially common in WordPress websites that end up having analytics code inserted both in your template and also in an SEO plugin.
It's also possible that your website or landing page is so well optimized that all of your users interact and stay on-site.
