Give what your visitors actually wants. Don't give the same thing that is already existing online. Do some R&D regarding your niche website and search what is already existing and what is not. Users are always hungry for something new, if they found it in your site, they will stay..
In response to your question, one of the things that can help reduce the bounce rate is to optimize the loading time of the page. A site that loads slowly hinders any any kind of engagement and therefore lacks the ability to keep your visitors interests and then they pretty much go elsewhere.
Another thing that can reduce the bounce rate is making sure the site is not overwhelmed with advertisements. Having ads understandably can be a way of bringing in revenue but...... it can also deter viewers to stay on your site especially if the site has more ads than actual content. Eliminate a couple of the "underperforming ads" and see if the bounce rate improves.
Make your website attractive enough to make the visitors stay longer on it and visit its other pages. Put the right content, images, video etc. on your webpage and check if it makes any difference.
Just make sure that the landing page is well optimized and from there users atleast navigate to some other pages as well... This will help you decrease the load time
Good quality content is the first thing. I high bounce rate could mean that you are showing up in search results but your content is not very relevant to the search term used. You need to use clear, unambiguous titles, make sure the content relates to the title and also make sure that your meta data relates to your content.
By using quality content and put all the information on your web page. When the visitor will come to your site then he will find all the information on your web page. If you are doing yet. Your bounce rate will be reduce.
Bounce rate is an important factor to increase the website popularity in search engines. Bounce rate can be decreased using a good website content, quick loading time of your webpage, easy navigation, user friendly design and various other factors.
