So after figuring out how to cloak, I have decided to try out Facebook. Had some experience with Teespring before.
But I still have a question I hope you guys could enlighten me 
1) For example, if I run a Walmart voucher sweepstakes offer, how would my Safe Page for Facebook reviewer would look like? I mean it makes sense for a Safe Page when you run nultra or skin products, but for vouchers or sweepstakes, I don't really see it.
Thank you
In general it is good to use a Safe Page, to protect your campaign.
Although, since sweepstakes are CPL offers, you should concentrate more on making a good pre-lander (landing page), than on a Safe Page.
We typically just make a blog post on a new site with facts or information about the product we are promoting, seems to work great for a safe page.
Hi,
Google legit giveaways related to your product.
Promoting Amazon vouchers? You will find legit giveaways for them, use them as your safe page.
Create a blog post with details on how to win X, info on the product and giveaways.
Should be able to run smoothly.
Best
Also keep in mind, when you run a safe page you need to contain a privacy policy, disclaimer and contact us form to comply with FB's ad rules. So just make sure those are added to your safe page.
