It really all depends on your "niche" to figure out what is normal. I would say that your site is normal because the spanish niche does not rank very high in overall profits per click.
I will like to ask you- which website are you using?Forum?Blog or regular websites? Good hope for Blogs and bad hope for forums with 1000 uniques/day There is no basis for regular websites...
it seems normal as you will earn depend on how many click your visitors did. If you have 10000 visitor but didn't click on your ads then you will get nothing
Your problem is probably your niche. You're not going to get much per click. Try to optimize your ads best you can. Try different placement and ad formats and remove any poorly performing ad/link units.
