I can think of a few:

1. don't power it on unless you have to;

2. don't write to it unless you have to;

3. write as little data to you as you can - compress the data; only write to it during brown out or power down, ...;

4. level the writes to as many cells as possible - increment the write address with subsequent writes;

5. use a big eeprom;

6. use fram;

7. use sram + battery back-up;

...

3 - 7 are really examples of implementating 2).
