Having problems with espionage

So once again I'm sure to be missing an obvious step. I place my spies on enemy planets in hopes of disrupting economy or whatever. They seem to last a turn, sometimes even two. Is this the norm, or is their a way to increase their skill level so they stay longer? Also whenever I try to find the level of influence I have over a planet with a spy on it I'm informed that my espionage level is not high enough. How do I increase this? The only espionage related item in the tech tree is counter intelligence. Thanks for any help you could offer.

Don't place one or two. Place a bunch. That way the AI can't nullify all of them.

You get a higher espionage level by having had spies on the AI's planets for a number of turns. The longer the spies are in place and the greater number of spies the faster this will increase. You'll get a prompt when you hit the next 'level' of espionage.
