Links to external websites are some of the most retweeted content. Hashtags link to similar topics within Twitter, so they’re a great way to gain followers and join conversations.
Tweets with links are retweeted more than those without. Since your client will supply any links that you include, you don’t have much control there. But you can decide where to place that link. 25% of the way through your tweet is the best place. This position gives you room for a brief introduction to the link, but doesn’t bury the link too low in your tweet.
Your headline is what you write with the link you provide. Copyblogger recommends following the four U’s for great headlines:
In a tweet, all your words are key. If you’ve got keywords that you’re targeting, your whole tweet should focus around them.
Keywords are what interested followers will notice as they scroll through their Twitter stream. You can leave your keywords as normal text, or you can make them hashtags…
Hashtags start with the # sign, and are followed by a keyword or topic.
Clicking on a hashtag leads you to other tweets that use the same hashtag. Making your keywords a hashtag helps more people find your tweets.
You can include a hashtag in a sentence, or just tack it on at the end of your tweet.
Example: Improve your #writing with #CrowdContentUniversity.

One or two hashtags are the hashtag sweetspot. Any more and you look spammy.
