Hi 90802,
To be honest, it seems to be that you are not using profitable keywords.
For every Tier 2 you need to have Demand above 1000 and supply below 1000.
For every Tier 3 you need Demand above 150-200 and supply below 100.
I could be totally wrong here. I just woke up so if you're already doing this then ignore me, but if you're coming up with stuff that you "think" your visitors want then you're in for a bumpy ride.
You have to brainstorm Tier 2s and 3s after profitable keywords. Having parts of a song be the filename for all tier 3 pages shows some fundamental flaws in your keywords, you want a separate filename for every page and write pages for stuff that people are actually searching.
I just checked out your Tier 2 "Parts of a Song" and it is better suited for a Tier 3.
It had Demand 356, Supply 39. It is perfect for a Tier 3 but not a Tier 2.
Look at the keyword "how to write a song" for example, it has a Demand of 4,933 and Supply of 223. A perfect Tier 2, and you could have parts of a song as a Tier 3. That is how you should structure your pages.
You have to be ruthless with keywords if you want traffic, otherwise you'll be stuck after 6-12 months complaining that you only have 25 visitors/day and you don't know what went wrong
Use these guidelines:
Tier 2: Minimum... Demand 1000+, Supply under 1000
Tier 3: Minimum... Demand 150-200+, Supply under 100
If you deviate from these (like most who don't get traffic do) you'll have trouble.
