How do I remove the Single Post function?

Hi, I’m diving into a bit of SEO and I’ve found that for every post I create on my website, there’s a single post page that gets generated to display just that post. In my website’s case, the entire post is always displayed on the homepage so I don’t have any use for these extra webpages – especially since I have to pay them attention when it comes to SEO (keywords, meta tags, etc.)…

SO, I removed all the data in the single.php file (it’s saved in a text file if I need it back) and I disabled the post title link function in the post.php file (also saved).

Now the problem is my SEO gadget keeps indexing those pages generated from the single post function, any ideas on how to delete those pages since I never use them/want them to be available?

I’ve searched for an answer but nothing seems to address this issue directly. Any help would be greatly appreciated, thank you.
