To celebrate National Etiquette Week (May 10-14), I’m covering social networking etiquette tips for job seekers this week – one tip each day.

Tip #1: Do not sync all status updates on all Big 3 sites.

Some people sync their Twitter and Facebook status updates; others sync their Twitter and LinkedIn updates. Is this a good idea for job seekers?

Generally, no. Here are three reasons why job seekers shouldn’t sync all status updates.

1. Audience. You communicate with a different audience on each of the Big 3 sites. For example, your Facebook audience is more personal than your Twitter audience. Do you really want to share your status updates about the struggles of potty-training your child on Twitter (and, thus with potential employers)?

2. Frequency. Twitter is conversational. You may post 20 times a day while sharing information and responding to other users’ tweets. You are lucky if your LinkedIn audience reads status updates once a day. Most people must log on to LinkedIn to read updates and this usually happens weekly when they receive their network updates via the weekly email. Your LinkedIn audience is likely going to miss one or several of your updates if you share 20 in one day.

Moreover, your updates will clog your LinkedIn connections’ news feed. The LinkedIn news feed displays only three status updates from connections; it displays eight updates if you click to “see more updates.” It annoys employers to see all three updates from the same person. They want to see updates from three different connections, not the same person. For example, 6 of the 8 LinkedIn status updates in my news feed this morning were from the same person because they were synced to his Twitter feed. I’d much rather read eight different updates from eight different connections.

3. Confusion. Your Twitter updates may confuse your non-tweeting LinkedIn and Facebook audiences – especially if they contain RT or @ or DM. What if your potential employer is only on LinkedIn? You don’t want to annoy or confuse him with your Twitter lingo.
