Yes it depends on which page you are posting your post, i suggest you one link per post is enough in social media sites. or else you can activate signature in forum posting which contains three links.
Hi there, There are no rules regarding to "how many" links... BUT, as for doing it right, just don't over what comes to be 'bad' publish.... As @reenajoon mentioned, Don't use more than 8-12 links... And don't use the maximim... Use between 8-12.. Good Luck!
I can't get your question... You can literally create thousands of links... Are you asking about backlinks to other websites?!? If yes, then be sure to use as less backlinks to other websites as you can because this way you boost their PR and SERP... If I understood your question good...
There is no specific rule about this but 9 or 10 links would be enough and pay attention to original and useful content as quality of the content matters a lot
