If you read a tweet in someone else's Twitter stream and like what that person says, you can retweet it (abbreviated as RT) and share it on your own Twitter stream. To do so, simply add RT and the original poster's Twitter username within your tweet (for example, "RT @susangunelius" would indicate you're retweeting, or republishing, something that I already published on my Twitter stream).

The retweet tag is an unofficial way to provide attribution to the original publisher.

Sometimes it's necessary to provide a link to a specific tweet. The most common scenario is when you would like someone else to retweet your tweet, so you want to send them to that specific Twitter post.

1. Log into your Twitter account.
2. Locate the Tweet you want to share, either in your timeline or in your list of previous teets.
3. Look for the timestamp (i.e. 1 hour ago) and click it.
4. Your tweet will open in a new window with a unique URL that you can copy and paste as needed.

Now you can direct people to any specific tweet that you want.

The answer, of course, is that it depends. Here are some considerations:

• Post Twitter updates regularly enough so that your followers see that you're active and engaging.
• Do not post so often that you might be considered spam.
• You can tweet the same post if you want to, but avoid doing it over and over again in rapid succession. It's better to space it out and also rephrase if you can.
• Try not to be sporadic in your posts. Be consistent in the number of tweets and space them out throughout the day.
• Definitely do not "shotgun" tweets and post a bunch of posts all at once.
• It can help to use a tool like HootSuite to create posts in advance and schedule them to be sent throughout the day/week. You can import posts via spreadsheet and use that to ensure that you're posting regularly and staying on topic.

The hashtag is a tool to link your statement to other similar tweets. As a business, it's a good idea to use hashtags to link new tweets with old tweets on the same topic, like #SocialMedia. Hashtag words are automatically linked as a keyword search in Twitter.

If you already used the phrase in your tweet, it's generally considered bad form to repeat the phrase with a hashtag. You could, however, add a hashtag in front of the phrase within your tweet. Hashtags do not have to always appear at the end.

If you have something to say on a trending topic, be sure to include the hashtag. However, avoid commenting simply because it's a trending topic.

Finally, don't hesitate to include hashtags on some of your other social platforms since savvy users may paste the tag into Twitter and look up your old tweets. #TwiiterTip
