It’s Twitter Tip Tuesday — every Tuesday we’ll focus on one Twitter Tip and show you how to integrate it into your social media strategy.

Last week we showed you five innovative Twitter tactics that can help you up your Twitter game from beginner to seasoned pro. This week, we’re showcasing four complementary Twitter tools that you can use for (among other things) competitive intelligence and self-promotion. In some cases, these tips represent Twitter tools — or features of these tools — that not everyone is using, so they can help you get the upper hand on your competition.

Look for links to the original articles where’ll you’ll find more detailed information and instructions on how to implement these very effective Twitter tools.

1. Make Introductions Like a Pro

Sometimes, we may forget that being “social” is the key to success when using social media for your business. And one of the most effective ways of being social is to introduce people who you think may benefit from knowing each other.

When you introduce two people on Twitter, the primary benefit of this introduction is that the two parties will discover someone new and develop a relationship that hadn’t existed before. The introduction may lose some of its impact, however, if the two people being introduced already know each other.

A great tool to check whether two people are following each other is Doesfollow.com. Simply plug the two Twitter handles into the simple, Google-like interface, and you’ll know instantly whether or not the two people you’re about to introduce are already following each other on Twitter. You’ll look like a pro, and your friends will get more benefit, if you stick to interactions where the people are discovering each other for the first time through your introduction.

2. Use History Feature to Track Past Interactions

If you’ve ever used Twitter’s search tool, you’ll know how difficult it can be to find previous conversations you’ve had with other tweeters. Searching for a specific Twitter handle yields every mention of that person on Twitter, and your tweets to him or her can easily get lost in the clutter.

Instead, try searching for that person using the versatile social media management tool, Sprout Social. When you search for anyone on Twitter using Sprout Social, you’ll automatically be presented with the entire history of tweets between you and that person. This can be a very efficient way to find specific tweets, links or conversations that you’ve had with people in the past that warrant another look.

3. Use Twitpic to Increase Your Content Views

As evidenced by the success of image-based social media platforms like Pinterest and Instagram, it’s obvious that images represent some of the most popular and shared content on social media. Consider alternating your tweets with links to images that can help tell your brand’s story.

Twitpic is one of the easiest photo sharing tools that also integrates heavily with Twitter. Once you upload a picture to Twitter through Twitpic, you can simply hit your browser’s refresh button to see the image view counter increment in real-time. Anyone viewing your picture can leave a comment, which is automatically tweeted out to his or her followers with a link back to the Twitpic image. If you’re on the go, check out Twitpic’s mobile app version as well.

4. Use Tweetvite to Promote Your Event

Although it was designed specifically to create invitations for Tweetups — face-to-face gatherings of social media friends — Tweetvite can be used to promote any type of event you like. Have a product launch coming up? Are you hosting an Open House or a Customer Appreciation Day? Tweetvite can be used effectively to integrate and promote these types of events with Twitter.

For example, your invitees can sign in to your Tweetvite invitation with Twitter and publicly RSVP to your event. Invitees can interact with other on Twitter simply by clicking on their Twitter profile pictures from within the Tweetvite invitation.

Other integrations with Twitter include the ability to assign a hashtag for the event. Any comments that your invitees make in the comments section can also be copied to Twitter with a link back to your event. If you need a little inspiration, here’s an example of a grassroots Tweetvite that incorporates many of the features Tweetvite has to offer.
