Some data on PPC / serp / banner profitability

A small player, but still...

[Algebrator]

This is my sales/profit data for the months of March/ April.

________sales____advcost____profit
google____7380____2100____5280
overture__1872____800____1072
serp______4896____0____4896
findwhat__324____236____88
looksmart_504____170____334
banner1*__1656____300____1356
banner2*__1332____700____632

(banner 1 and banner 2 - I have a simple text banner on the top of the homepage of these 2 sites - they are largely non-profit and both are in top 5 google serps for my main keyword)
My CTRs are approximately 1.5 and conversion rate about 1%

I also have a question - where to go from here?
Ideas so far:
1. Have a better site (1% conversion is way too low) - I am working on it
2. Banners seems profitable - continue looking at similar opporunities?
3. More PPCs - hardly seems worth it (look at FW and LS data)?
4. More SEO?
5. Other forms of adv - print media?
6. Anything else? I have money to spend, I just don't know where to spend it most effectively

# 2, definitely.

> Banners seem profitable - continue looking at similar opporunities?

Banners are profitable, but the most profitable ones will require some digging. I suggest searching in your niche for sites with high informational content and low commercialization. Ask for stats, look for the "no brainer" flat-rate deal.

Yes, the two that I have are exactly the ones you are describing - I will go dig up some more...
