Anybody can give me novice advice for a new slots website

[MAC]

Hi all,
I am a poker affiliate who tried only a couple of casino websites with no success (not enough dedication also).
After playing myself some slots I decided to create a new website only for slots in my native language, spanish.
Its almost finished to be online but I would like to receive some advice on call to actions and content of the articles I plan to write.

For the website I decide to promote 5 casinos, only one casino for each top network (ipoker, microgaming, 888) and a couple of casinos (supposed to be good) for spanish players.
Then started to test slots to create reviews for as many slot games as possible and including playable flash previews on each review.

For articles I am thinking about some:
kinds of slots: multiline, video, classic, progressive, ...
history of slots
strategy: don't know if there is an strategy
...

What content does convert better for slots players?
What call to actions are better?
Win a big Jackpot?, play this great slot?, try this succesful new slot?, with this bonus you won't loose and have a great time?,....

Does free spins convert? For example the PlatinumPlay 1500 $ free bets

Thanks in advance for your help and sorry for my bad english.

Good month $$ to all!

Anything doing with FREE does not really convert. Try talking about the deposit bonuses , or slot tournaments that some sites have. Seems to convert better.

Great Lenny, I forgot about tournaments

Whats good about a lot of the slot tournaments is that its free entry, but then the players have a choice to rebuy. So this helps conversions out a bit.

Thou to be honest with you a lot of casinos which cater to usa players have been slow with the deposits, think there all having processor problems with there credit cards. Ive taken a beating the past three months, while signups and clicks have stayed the same, so im attributing it to cc processors. Hopefully they find some new ways to get cc to work.

Pokerrooms seem to have less credit card processing problems, thinking why dont these casinos also open poker rooms and use them to transfer money between them.
