Can Baidu make it clear? Bidding or seo!?

Remember the last time to participate in Baidu New Customer marketing Conference (I was invited to the old customers), very sad, I went to I did not get the answer I want, even a little overwhelmed.

I have long been to our company's website to do SEO, our company's Web site in Google's ranking is not bad, only recently fell to the second page. We have a few keywords in Baidu is to do the bidding rankings, so I would like to know if I was sentenced to SEO black hat words on the impact of the bidding.

So after I had fought for a few minutes, I got such a precious opportunity from all of them, I asked the "experts" on the stage, the question is this: Excuse me for the company's website to do SEO, and was sentenced to SEO black hat, will not affect my bid ranking, my site will be Baidu put on the blacklist was kicked off?

After several thoughts, the expert comrades squeezed out so many words from his teeth that it was a commercial activity for the bidding rankings and he would not have any impact on your site. And then no more answers. Then I feel a little weird? If my SEO is a bit over, then according to Baidu's own answer does not allow cheating phenomenon exists, will cheat the site kicked out of Baidu, but I bought a bid ranking then I will not be kicked out?

Here is sure that Baidu has encountered a dilemma, if the play so that the effectiveness of the business, whether it violates the bidding contract. If not kicking on the impact of the search experience of netizens, it is not fundamentally contrary to the pursuit of Baidu goal.

My humble opinion? Also please master or Baidu answer, bidding and SEO where to go? How should I choose?
