2. Link Your Social Networks
You may not be a Twitter superstar--I'm certainly not. But even if Twitter isn't your thing, you can cobble together a respectable Klout score. You can link up to 13 social networking accounts to Klout, including Blogger, Facebook, Flickr, Foursquare, Google+, Instagram, Last.fm, LinkedIn, Wordpress, and YouTube. Klout plans to add at least seven more social networks, including Yelp and Posterous, to its roster.
Klout says that connecting networks can only help your score, and it recognizes how "nearly impossible [it is] for any person to be consistently effective across every network." That said, you should link only to accounts that you keep up with, according to social media expert (and founder of new media agency Plastick Media) Tori Kyes. You should also make your linked accounts public.
3. Build Relationships
Your True Reach is a measure of people who not only follow you and friend you, but who actually engage with the content you produce. Having 3 million Twitter followers won't mean much if they follow you but otherwise ignore you.
To increase your True Reach, you must build online relationships with people. The easiest way to do that is by talking to them--responding to their content, asking them questions, or commenting on their profiles. This will put you on their radar, and in the future they'll be more likely to respond to your content.
Klout says that it never punishes users for interacting with people who have lower Klout scores, so you should try to talk to everyone when you have the chance.
4. Pay Special Attention to Influencers
Since Klout rewards you for engaging with people who have higher Klout scores, it's worth your while to identify "Influencers"--people who have high Klout scores in your field of expertise--and try to engage with them without looking like a suck-up or a social climber.
"Don't just retweet them; that means nothing," says Rachel Hutman, an account executive at Clearpoint Agency. "Respond to what they are saying. Ask them additional questions. Be enlightening, funny to get their attention. The more followers someone has, if they then talk about you, your Klout score will undoubtedly go up."
You can also engage with Influencers who are not in your field of expertise, but you're more likely to receive a retweet or a comment if they have a reason to talk to you. As a tech writer I'm more likely to get a comment from another tech writer (say, about technology) than I am to get a comment from rapper 50 Cent. Though it would be awesome if I got a comment from 50 Cent, it makes more sense for me to solicit comments from other tech-focused people.
5. Ask Questions
The more questions you ask, the more answers you'll get. People love to give their opinions--whether about the weather in Seattle, which Android phone to buy, or how insane traffic is during rush hour in New York City.
Tweeting something like, "What's the craziest thing you've ever done to get a cab at rush hour in NYC?" will elicit more responses than, "Ugh. Trying to get a cab in NYC." Likewise, asking people if the sun ever shines in Seattle during the summer will net more answers than just complaining about the weather.
One especially effective strategy id to ask people to share their own stories. People love to talk about themselves, especially on the Internet.
6. Know Your Audience
Once you get to know your audience, you'll be able to share, comment on, and ask questions about topics that interest them; and in turn, they'll be more likely to engage with you. If your audience is mostly teenagers, you probably shouldn't tweet incessantly about politics and finance. If your audience is mostly Silicon Valley computer engineers, you probably shouldn't bore them with makeup tips.
It's also smart to find out where your audience is located. If you have a ton of followers from Japan, for example, you might want to send out tweets at times when they'll be awake. If the vast majority of your followers are on the east coast, you can taper off the tweets at around 10 p.m. Pacific time.
