If a keyword is below first page bid (or below top of page bid), but conversion rate allows for increase, make the increase regardless of conversion volumne #4
The bids for low volume keywords will often remain stagnant due to conversion volume being below the threshold. But sometimes, these keywords fall below the first page bid or top of page bid.
So, for any keyword that is below top of page bid but has at least 1 conversion, increase bid to MAX( top page, max bid).
For any keyword with zero conversions that is below first page bid, but cost < 10% of max CPA, increase bid to first page bid.
