Can Yelp Be Pushed?

I have a client who has Yelp in the #2 position for their business name. Looking to get it pushed to second page. I'm researching both WH and BH approaches. I've been creating social media profiles, EMD's, blogs, etc. and backlinking...but Yelp is stubborn. I'm interested to know if anyone here has successfully pushed yelp to the second page and if so, I would like to discuss.

yes, it's entirely possible though challenging as is any authority site of that size. I would advise against slamming the Yelp page with bad links as it tends to back fire and just makes it harder to knock out.
