I have a website with a url for example: https:// www. abc.com but when auditing its shows urls of my home page like

https:// www. abc.com/a5158c15_page=2 https:// www. abc.com/a5158c15_page=3 https:// www. abc.com/a5158c15_page=4 https:// www. abc.com/a5158c15_page=5

When clicked upon they land me on my home page with that url. How should I block or remove them and keep my main url.
