The Biggest problem is after a decade,Ciara doesn't have a signature sound or a large enough fan-base.
Besides that, the true blade in the heart of her career occurred during the hiatus between Evolution and Fantasy Ride.
The general public lost interest during that time and for her return single she chose "Neva Eva" and the rest is history.
Ciara has never recovered from that and honestly I don't think she will.I don't hate Ciara, as I have all 5 albums.I just think people need to be realistic about things. After 3 commercial failures she is lucky to still have a deal. Just look at Kelly Rowland,technically had only one album flop on her and she was dropped from Columbia Records(Simply Deep did ok)

Maybe she needs to go indie if she can't manage to sell 500,000 worldwide
