Have you ever join a group on Facebook? If not then you'll probably need to do it now because this is where all the gems or gold are. If pages are great then facebook groups are even more interesting because joining is easy and interaction with other people can be helpful.
So here's how to join facebook group:
1. Login to your Facebook account, then in the search box type anything that is related to your busines or product. In this example I will be promoting about Relationship and Marriage ebook - so I will be search about Relationship Advice. Press ENTER. see image below
2. Next is to click Groups tab. Please see screenshot
3. You will now see a list of groups - find a group that has more users then click JOIN - wait for the Admin for approval before you can post anything.
Do not stop on 1 group, join as many as you can and try to be active in the group.
When you get approve, do not promote any links yet. Simply join the discussion and share your own opinion about the topic. And be nice in the community.
Once you get things right, you can now simply apply the same technique by uploading image with description and product link. Again do not spam the group, or else you will be banned.
