Hashtags are a way of tracking topics on Twitter. When you use hashtags, you can help people who are interested in your subject matter find your Tweets.
You add hashtags to your Tweets by using the number sign, #, and a word that defines the Tweet's topic. For example, #sweepstakes or #about. You can include more than one hashtag in your Tweet, if appropriate.
You can also search for Tweets with hashtags that interest you. Some hashtags that sweepstakes fans might enjoy include:
Using Hashtags to Enter Twitter Contests:
Many Twitter sweepstakes use hashtags to identify entries. You may be asked to answer a question, give an opinion, or share a story, followed by a specific hashtag to enter.
Here's an example of a hypothetical invitation to enter a Twitter sweepstakes using a hashtag:
Send a Tweet about your favorite summer memory followed by the hashtag #winningsummer to enter.
An entry into that sweepstakes might look like this:
My favorite summer memory is going to the state fair with my family when I was 5. I won a prize at ring toss! #winningsummer
Tip to win sweepstakes: use a separate email for entering. #sweepstakes #about ("#sweepstakes" and "#about" are both hashtags)
