Help installing affiliate link Please

I am trying to install an affiliate link on the front page of my site that when clicked on will take viewer to a product offer and need some help please.

I need to link to be located at the end of my post (Not on Sidebar)so viewers can easily access it after reading the post.

Via a post I read on this forum I was able to install link to the sidebar, but that’s not where it needs to be.

Also, when I run my cursor over the link it does not highlight so I would not be able to access that site.

If anyone can guide me on this I would greatly appreciate it, I am leaving the link on the sidebar for now if anyone needs to see what I have done.

My site url is https://www.alphaaffiliatereview.net

Regards,

Bill
