If you are in weight loss niche,please tell me which traffic source works for you

I usually spend $25 - $50 on Bing Ads to get 100 targeted visitors. But don't direct link to your product sales page. Create a high quality lead magnet and build your list linking your ad to the opt-in page. Otherwise you won't make any money. It's email marketing that converts people into buyers.

What kind of images do you post on Pinterest and what do you link them to? I buy stock image packages monthly to be able to distribute great pictures across all my social media profiles. I upload them to Pinterest boards and link each one to my lead capture pages offering a free webinar registration or a free ebook.

The key to getting followers and traffic is group boards. I join relevant group boards to pin my content. I create my own group boards and search Pinterest for people who might be interested to become a contributor. If they're not my followers, I reach out to them via Twitter to invite for a collaboration. You can get a lot of established bloggers together to pin to your group board and grow your exposure as your group board appears in their profiles. Let's say you got 100 contributors and each one is followed by at least 3,000 followers, that's a huge potential reach for your business.

Also, I send some pins directly to my followers offering them some special value for free.

Have you ever considered that asking your direct competitors to divulge their best traffic sources may not be in their best interest?
