Need help pulling news feeds from facebook and web into Weebly website

I have a Weebly website. The topic of the site is bone broth. I have successfully been able to pull tweets pertaining to bone broth onto the site using Blastcasta. I would also like to be able to pull content from any facebook page that mentions bone broth and from any news article that mentions bone broth. So I need help doing this.

In Weebly you can edit your site with HTML, CSS and Javascript (client-side languages); however, Weebly does not support building your site with server-side languages, such as PHP or ASP. Weebly also does not currently offer database access. It is quite simple to upload HTML to the site, though.
