ok, i thought i had a clue about how this works but i guess i was way wrong. i've submitted about 70 keywords/phrases and so far only 2 decisions have shown up. i got the following terms rejected for being "duplicate search terms": "international student scholarship grant" and "international grant." i guess because the second term was contained in the first. this, however, totally confuses me. i thought you were supposed to bid on different permutations. by their rational, it looks like they'll reject just about all my submissions .
can anyone explain this so even I can understand what's going on? i'd be enormously greatful.
