How to make webpage available in Google search

I'd created a custom webpage about Table Topics ideas on my club website, cyberjaya.toastmastersclubs.org/800__Table_Topics_Ideas.html . I noticed that the webpage received high traffic on Google Analytics because I had shared the webpage with people. However, when I search it in Google, it didn't appear in the ranking and even anywhere in search. How to make the webpage available in Google search?

1) load the content directly on the page, you have it as an iframe so your site does not own the content.

2) You have nothing on your home page to attract the search engines.

3) read the documentation
