Some of the tools are clearly for Professional use, but some do step either way across the line.
One potential way of keeping things apart is multiple accounts on a platform, one personal and one professional, but it is important to understand and set some guidelines on how you use these.
If you are communicating on Social Media representing an employer, always check their policy on Social Media and communications.
If you don’t have any, there are a number of good rules available. Kevan Lee has done some research into these and had come up with a list of 29 Social Media Rules
For all social networks
1. Share several times a day, but space out your posts every few hours.
2. Respond to all comments as quickly as you can.
3. Know the art of the hashtag. 1 hashtag is fine. 10 hashtags are not.
4. Always keep the 80/20 rule! Entertain and inform your audience first, sell to them second.
5. Use first person plural when talking about your company brand (We, Us).
For Twitter
6. Don’t automatically direct message people that follow you.
7. Don’t use all 140 characters. Give people room to retweet with a reply.
8. Don’t hijack another company’s hashtag.
9. Don’t buy followers.
10. Don’t stuff your tweets with keywords.
For Facebook
11. Don’t Like your own post.
12. Don’t post or tag photos of fans, customers, or employees without permission.
13. Don’t tag people or pages that aren’t relevant to your post.
14. Don’t ask for Likes, Comments, or Shares.
LinkedIn
15. Personalize your connection requests. Tell them WHY you’re connecting.
16. Once connected, send a “welcome” message.
17. Don’t join groups and immediately start selling yourself.
18. Don’t ignore the more professional tone of the network.
Google+
19. Always +mention users when commenting on their posts.
20. When sharing a post, always add your own commentary to it first.
21. Share to Circles to target your content.
22. Use Google+ formatting for your text—bold, italics, and strikethrough.
Pinterest
23. Don’t neglect to provide good descriptions for your pins.
24. Always link back to the original source and give credit.
25. Don’t use images that have nothing to do with your clickthrough content to get more pins or clicks.
26. Don’t pin just your own material.
Instagram
27. Don’t ask people to follow you or use hashtags like #tagsforlikes – it’s unprofessional.
28. Don’t overgram. No one likes their feed filled up with one user.
29. Use hashtags for your brand appropriately. The golden number of hashtags is 11.
