None of the pages have "No Index or No Follow" tags, however, when you try to find the pages on Google search they simply don't show up. Some of them do some don't (even after weeks of being published).
Example of page not showing up in Google: Stand Out Contest – Moneydiver Podcast
Example of page showing up: Social Media Strategy Contest - Jason Falls
As you can see, both pages have similar structures and both contain links.
I'm asking because I need my podcast listeners to be able to find the pages, Why do you think this is happening?
