I’ve often said that the best use of Twitter is as a broadcast medium. You should be creating a ton of interesting content and sharing it with your followers. To that end I’ve done a bunch of research on how to optimize the clickthrough rate (CTR) of the links you’re tweeting.

For the purposes of this data, I’ve calculated CTR as the number of clicks on a tweeted link divided by the number of followers the account had when it tweeted that link.

Below is an infographic presenting some of my past findings as well as some entirely new data I’ve found about increasing CTRs on Twitter.

One of the most popular webinars I’ve ever worked on, The Science of Timing was also one of my favorite. If you haven’t seen it, go check out the on-demand recording now.

In it, I present data I’ve collected over three years about the effect timing has on a variety of online marketing activities, including blogging. Below is an infographic that represents a collection of the three most important stats I have about when to publish blog posts.

In the webinar, I also make the point that my results are based on huge aggregates of thousands, millions, or even in some cases, billions of lines of data. They might not represent the exact best times for your industry. What they represent is a set of times to experiment with, using your own audience.

As in the medical science field, researchers conduct experiments with hundreds or thousands of subjects and find best-practice courses of treatment. In individual cases, doctors start with these best-practices and if they work, great. If they don’t work, they experiment with the next course of treatment. Marketing science is like this. Use my data as a starting point for your own experimentation.

I’ve studied the relationship between Twitter success and politics before, and since this year is a big year in elections, I figured I’d do it again.

This time I looked at how the 4 front-running republican presidential candidates are doing on Twitter. I analyzed the obvious numbers, followers, retweets and mentions, but I also looked at a few of my favorite, deeper metrics: retweets-per-follower, link-percentage and reply-percentage. I also looked at Twitter “penetration” in two upcoming primary states: South Carolina and Florida. Notice anything that surprises you in this data?

One of the most interesting patterns I’ve found while studying social media and marketing data is what I call in my book “contra-competitive timing.” I’ve found in numerous cases that the most successful times and days to publish new content are off-peak times.

It’s like when you’re at a noisy party and it’s hard to hear the person talking to you 2 feet away, but suddenly you say something awkward and the room quiets down. Now everyone can hear you. The same is true with the internet. When there is less other noise to compete with (ie fewer Tweets, emails, blog posts, etc) your content can gain attention more easily.

The infographic below showcases some of the best examples of this phenomenon I’ve identified.

If you like myth busting social media data like this, be sure to buy my newest book, Zarrella’s Hierarchy of Contagiousness.

One of the social media questions I’m most interested in is about whether Twitter is best suited for conversation or broadcasting. To many people’s surprise, I generally find myself on the broadcast side, and most of the data I’ve analyzed seems to back me up.

Just yesterday, I started a little informal Twitter poll and found that respondents were pretty evenly split between broadcasting and conversation.

This time, I looked at more than 100k randomly chosen active Twitter accounts and their Tweets. I analyzed the percentage of their Tweets than contain a link as well as the percentage that began with an @. I also measured the percentage of their last 100 Tweets that were ReTweeted.

I found that accounts that had high link-percentages between 60% and 80% had the most ReTweets and accounts with low reply-percentages between 0% and 10% had the most ReTweets.

If you’re interested in ReTweets, broadcasting lots of interesting content works much better than “engaging in the conversation.”

The recent launch of Marketing Grader is a boon for me because it gathers a ton more data than its predecessor, allowing me to analyze all sorts of stuff I couldn’t before.

One such area of exploration, is the relationship between a brand’s Klout score and the successfulness of its website. Among its 38 metrics, Marketing Grader analyzes the Klout score of a brand’s Twitter account, the number of domains linking to the brand’s website (as reported by SEOmoz) as well as the number of unique visitors it gets (as reported by Compete).

When I analyzed the relationship of these numbers I was surprised at what I found.

Brands with higher Klout scores tended to get more visitors and more links. And when they have really high Klout scores (like above 70) they get far more traffic and links than other sites. Of course this isn’t causation, but correlation. It means that Klout may be a surprisingly effective measure of overall online marketing success.

The data tells us, not only only does Klout-measured social media influence translate into more traditional measures of web marketing effectiveness, but also that the web is a very winner-take-all kind of place. There are essentially two kinds of brands online, those with a ton of influence, traffic and links and those with very little.

After compiling a dataset of more than 200,000 link-containing Tweets to generate the CTR heatmap, I decided to dig into what words, phrases and characters correlate with higher (or lower CTR). Below are my findings. And yes, I know correlation isn’t causation, but to quote Edward Tufte: “it sure is a hint.”

The first “word” I analyzed was the hashtag. I found that there is very little difference in the CTR of a link whether or not it is accompanied by a hashtag. They don’t hurt or help.

Perhaps the most surprising thing I found is that Tweets that contained the words “daily is out” (which is the signature of the paper.li automated Tweets) had much higher CTRs than Tweets that did not. It turns out, paper.li works, at least for driving clicks.

I also found that Tweets using the word “via” as a method of ReTweeting had a higher CTR.

Somewhat unsurprisingly, Tweets specifically directed at a person tend to have a higher CTR since I’m much more likely to pay attention to a Tweet if it’s sent to me. This is probably the reason the paper.li Tweets do so well, they tend to contain 3 @-mentions.

Like the “via” ReTweeting syntax, Tweets with “RT” in them had a higher CTR than those that did not.

My data seems to indicate that when you politely ask people to do something, like a nice social call-to-action, they’re likely to do it.

Again, specifically asking readers to check out a link seems to result in a higher CTR than not doing that.

Now we get to the words that correlated with lowered CTRs. The first one I found was “@addthis” which is a signature for the Tweets that come from the automated AddThis sharing functionality.

Tweets that mention the word marketing have a lower CTR than Tweets that don’t mention it. Most marketers won’t be surprised by this.

The automated Tweets that come from the GetGlue system have a lower CTR than Tweets that don’t come from that system.

I’ve studied data from a variety of social media platforms, but never LinkedIn. So a few days ago I got around to playing with it a little bit and found a few interesting things.

First, I looked at the words in the title and summary of more than 40,000 randomly selected profiles and how they correlated with the number of connections those profiles have. I found that there are a handful of highly connected positions (unsurprisingly investors and recruiters) as well as under-connected titles (religion and healthcare).

The infographic below shows the 20 most connected common words (and the 20 least connected words) found in titles and summaries. The vertical axis is the percentage more (or fewer) connections profiles using those words had compared to the average in my dataset.

One of the questions that I’ve been asked the most in the years I’ve been doing Twitter data analysis is where in a Tweet is the best position (beginning, middle or end) to include a link to get the most clicks. I had always assumed the end was the best, so I never thought much about the question.

But about a month ago, I decided to actually look at the data about it and test my assumption. Over the course of the next few weeks I gathered 200,000, random, bit.ly-link-containing Tweets. I used the bit.ly API to calculate a click through rate (clicks on a link divided by number of followers of tweeter). And then I analyzed the relationship of the link’s position inside the Tweet and it’s CTR. I figured the best way to visualize this would be through a heat map.

The entire heat map symbolizes a Tweet, with areas to the left in the beginning of the Tweet and areas to the right at the end. Dark red bars represent a position with a high CTR and light-red or white bars show a position with a very low CTR.

It turns out that the best area for clicks is about 25% of the way through the Tweet. Do these findings match your experience? Will you be experimenting with this placement?
