How is CPM for each Hub determined?

    I only have one hub and I am enrolled in the Hubpages Ad program. My experience so far:

    May   CPM    $16.00

    June to date CPM  $14.83

    Yesterday CPM   $3.00

    How is the CPM for each hub determined? I can understand a drop from $16 to $14.83 but why would it suddenly drop down to $3.00?

    Is it normal to see such variation in CPM? What sort of range of CPMs are you seeing?

    Doesn't this sort of variation make it difficult to plan? For example I was quite excited to see a CPM of $16. I could have spent a lot of time to SEO this article only to see the CPM slump to $3.

    Apologies if these question are naive or answered elsewhere I have tried searching but haven't found answers to the above questions.
