Also, don't confuse your Bounce Rate with your Exit Rate. Bounce Rate means someone visited one page in your site and left. Exit Rate means they visited other pages on your site, but decided to leave on the page you're looking at the analytics for.
Thanks for the information.
Furthermore, I want to add a point from my side. I believe on the results of Google Analytics. The Bounce rate shown in Analytics indicates two problems, first the site is not good to attract visitors. They are hitting the landing pages, and not seeing what they exactly want and after that, moving on. If these are potential visitors, then you are losing the business. The landing pages require a review to be more attractive to visitors to stay on the page.
The second one could be that, your advertising is reaching to those who are not interested in what you are presenting them. This means your site getting in-organic traffic, and you are wasting money for ads that will not lead to efficient buyers. In this condition, you have to focus on your ads by location, topic, keywords and so on.
