Hi,
How long ago did you publish the page?
What you refer is "on page" elements: h1, title and URL are one part of the job. Sure, if you got the exact keyword match, you got more chances to get to the top SERP.
However, you're missing the second part of the job: links. You're page is new so you may not have any link. Here's a process you can use:
- Link the pages already well indexed you're referring to the new page.
- Use the MozBar to analyse the 2 first results, and check for the links of those pages. Do they have more than you?
- Scan those pages using https://moz.com/researchtools/ose/, and try to get their links.
- Scan also the top10 results on this keywords and go get some links
Best.
