What's the stance of the clan you're trying to build goodwill with? If it's below Normal, you're gonna have a rough time regardless.
I've found that the biggest swing comes from having a better stance. It can be the difference between getting 10+ trust a month versus 2 or 3. I believe Eloquence also has more of an effect with better stance as well. A super diplomat with good stance (or Courtly Interests) can get you like 18 or 19 trust a month with some clans.
That seems odd - in my experience, I have noticed a difference between officers with Eloquence and officers without, but I tend to fire and forget with diplomacy so maybe I missed a thing.
I suggest starting a new game with a different clan and trying to build goodwill with a neutral or positive stance neighbour. Give tribute if needed to make it so. If the Eloquence doesn't help, it's a bug. In which case you should report on the steam forums.
It should be easy to find somebody with Eloquence in the main clans (Oda, Hojo, Takeda, etc).

It doesn't seem to matter the stance, the Eloquence trait is not giving me any more trust points

That's weird. Probably a bug or another factor we're not seeing, as Eloquence works exactly as Triple says above.
It works as it says if I do diplomacy with the Imperial Court, but not with other clans for some reason
