Tell a Secret. Reveal something intimate. (But not, for example, that you are a shameless flatterer.) This suggests you like and trust the other person that you think she's understanding and discreet, and that you want the relationship to deepen.  You're flattering her with your trust.
Ask for advice.  We like people who think we are authorities. "Gee, Mr. Green, I was thinking of using that factory in Wisconsin to make widgets. You have a lot of experience with that - what do you think?"
Ask a small favor. As Plutarch and La Rochefoucauld suggested, we like people for whom we do favors more than people who do favors for us.
And here are tips on how to receive flattery'.
"I'm flattered." This can be said with a feeling of warmth, as though you are acknowledging the person's kindness, or it can be said with a kind of disengenuous modesty- that is, I completely agree with your evalauation, but it would be rude of me to say so.
"I  hope you'll speak at my funeral." This is ironic; it acknowledges the compliment while showing that you don't take it all that seriously.
Ignore it, but let the person know you received it.  This can be done with a smile or a knowing look, but you do not thank the person for it because you don't want to reckon with any implicit quid pro quo. It's the gift under the tree you choose not to open.
