Change URL when Post moves to 2nd page?

Aloha Bloggers,

I’m fairly new to Word Press. I have been posting articles on my blog, https://now4u-website.com/affiliatemarketingsecrets, and linking back to a specific article i.e. ing….secrets/affiliate-marketing-urgent-paypal-warning.

All was good until my original post got bumped to page 2. Now, the original link to that post goes to a 404. 2 questions …..

1. Once moved to page 2, is there a specific URL to link to that article only? (specific article, not page 2 in general).

2. Do I need to continually monitor every time I make a new post and then track down all of the invalid links and change them?

Also, when the post moves to page 2, it is removed from the RSS feed directory. Can I retain it?

Just for my information, what are the parameters for automatically developing a second page … # of posts, # of lines, #of words, # of days on main page, ???

Thanks,

Scratchin’ my head in Hawaii ??
