Post site link to group or post page post to group?

For the last few weeks I've been making some money by posting links to articles on my site to different niche groups.

I have recently started a Facebook page where I am auto posting snippets and links to new articles on my money site.

Now here's what I would like to know....would I now be better off posting links to my Facebook page snippets to these groups or carry on posting direct links to my money site? Long term I would like to be able to monetize the Facebook page as well

Thanks all!!
