They have had several increases in payouts over the last couple of years.
They had an increase of around 65% two months ago which took my average monthly payment up from around $900 to around $1600.
The payments are a little up and down from day to day, but will hopefully maintain their current average and perhaps continue increasing.
The new design looks more attractive and "professional" than the old one, in my opinion.
They also have a small number of images you can put at the top of the page (hopefully they will provide a lot more).
They also have one click landing pages for some domains (or keywords).
I love the ease of adding domains to trafficz.com and their stats.
The new domain manager is a bit different to the old one, and in some ways I prefer the old one.
