I recently created a page on my website with compelling content and proper SEO. Now, about 10 days later, I realize that I had another page targeting the same keyword that is a few years old. The old page is not optimized but it's ranking in Google because it's old.
What should I do for the new page to rank?
P.S. A while ago, I wanted to merge two old pages. So I moved the content from one page to the another, deleted the first one and redirected to the one with the merged content. I never recovered from that. Never ranked for that keyword again. So I'm really afraid of deleting old pages.
