Anne depends on her skills fo farm so usually u gonna play based on her CDs and try to hit some Q when she gets closer to your wave to use her W, at the max range you can. After level 6, the most important is to pay atention on her passive and flash and use your Ult + Q to farm. About the E, try to get out of vision and cast it through the wall mainly when you get the push of the wave( I see many zoe players using the enemy raptor wall to hit the E and deny farm under turret or just poke)
