Here’s what consumers have asked with answers from Weebly staff and previous consumers.
Weebly does allow facebook marketing on their site. You should take a look at their complete Terms of Service, the most important restriction on advertising is: (q) include more than three ad units per page, or any advertising that greatly reduces the usability of the site. So, you would need to be careful about how many banners you include. That being said, many of Weebly's templates work really well with affiliate sites. The ability to insert HTML and Javascript files gives you a lot of flexibility. I've created a couple of demo sites that show how you can use affiliate data feeds on a Weebly site. You can see them here: http://www.webbuildersguide.com/website-builders-reviews/weebly-review/
I have tried the same and contacting Weekly is futile. They could care less about their clients.
You need a paid plan, then you can get live customer service. You still can only get that during business hours. Keep your notes in front of you, they are tricky. Remember what you say in the live chat box because the chat box will not reveal what you were previously saying. They'll try to confuse you using that and try to change your story or something. Then they'll say is that all and end the conversation. Your problem not being solved you'll have to contact them again.
