I think my PPC earnings are the same (this time last year they were made just of Adsense, but now I'm referring to combined earnings of Adsense+HP ad program).
However my Amazon product sales are way down - November last year saw over $75 in commission from Amazon, while this month so far I'll be lucky to make $20 unless something changes!
(Please note that this is not my main account - I have several.)
The subdomain change by Hubpages in July caused a big influx of traffic for some and a big Google slap for others. The site is still very topsy turvy from a range of things including Panda in February, the changes the site made to the rules in the following 3 months and then the big subdomain change in July.
