Ads, Update. What's happened Leadbolt?

I had a create last month last month from ads, using mainly leadbolt, and a bit of admob.  During the second half of the month I was making between 40-80$ (30-65 Euros) a day.   This was mainly from Spain using my The Penalty of Ramos or (el Penalti de ramos) joke game.

But this month (even though it started well), I have only been making between 2-6$ a day and it looks like Leadbolt don't have many advertisers anymore, sometimes there aren't even any ads available in the country (at most there is just one)
As shown here, I'm not the only one to experience this.

I have enjoyed making money with Leadbolt and they are a business with a focus on making money, they have seemed to be a respectable one.   However, as well as moving to the 'easy to learn' and multi-platform monkey programming language, I'll probably be phasing out Leadbolt ads from current and future games.

 Any suggestions for good advertising networks?

New Plan of Action for Sionco

After careful thought I have come up with a plan for the immediate future of Sionco.

After, the recent success of my (admittedly) worst game el Penalti de Ramos, which I made as a joke for one of my students (I'm an English teacher in Spain), and the time it's taking to rewrite and re-plan my biggest project yet (a Formula One management game for Android and the PC), I've decided for the moment, to try and make a small Android arcade game every week (or every two weeks) and then when each game is completed, use any time left in that week to continue making the F1 Manager games.

The reason for this, is that I wish to make enough from advertising in the small games to be able to reduce my working hours a little (even if only 1 or 2 hours less) so that I will have more time to work on the big projects.

Admob

I'm disappointed with the amount of advertising money from leadbolt my second game, Pixel Strip has brought in.

The biggest winner from my hangman game ads, was the ad wall shown in between games of hangman, which has brought in $12.74 of the $18.55 dollars that I've reached so far (in nearly a month).

The Pixel Strip has about 2000 less users, but it still does have over 2000 downloads, so in theory should be making half the amount. I know the free version of Hangman has reached over 4500 downloads, from various app-stores.

So, I've decided to do two things, I've signed up to admob (which I believe offers a smaller amount, but it pays on clicks - leadbolt pays for completed actions; such as downloading the game advertised, but pays more., and placed a banner ad on the level select screen, depending on how much it makes, I will see if I'll replace the leadbolt banner ads with the admob banner ads. I've also put a content unlocker (a big banner of offers that covers the screen - as my hangman free version has) between games on Pixel Strip, however, I've included an optional close button to it.

I've also updated the advert banner positions in the hangman free version.
