Recently there has been quite a buzz about how much money Dell has made from sales in which the referring source was Twitter. I really appreciated Kevin Hillstrom’s take on it. Especially since I’ve been up in the air regarding the validity of social media as a credible marketing tool and have been looking for anything negative to be said. It’s so easy to be swept away. But putting this aside for a later post, back to Twitter sales and mathematics…
Online sales conversion rates are generally accepted to be between 2% and 5%. I really like to using the FireClick Index to keep an eye on this. They are currently reporting the top line conversion rate at 5.00%.
So let’s assume that 5% of your traffic from Twitter makes a purchase on your site. That’s nice, 5 out of 100 visitors from Twitter bought your products/services.
Now the hard question. How much effort does it take on your part to get 100 of your Twitter followers to click through to your website?
Taking the general marketing conversion rate to be between 2% and 5%, we’ll optimistically say that 5% of your followers will click through. Applying Bayes’ Theorem, that means that 0.25% of your Twitter followers will make a purchase on your website. To make one sale, you need about 400 followers.
Now let’s look at Dell to see if this math is credible. DellOutlet has about 1.5 million Twitter followers. The report stated that Dell made $6.5 million. Assuming 0.25% of their followers made a purchase makes the average purchase price at roughly $1,750. I suppose that could be realistic considering that there are some enterprise level items available through the Dell Outlet. [To someone in the know at Dell Outlet, I'd loooove to know how close I am to the average purchase price for Twitter visitors.]
I’m no expert at Twitter strategy, but my guess is that you need to dedicate some serious resources to get enough relevant followers to merit it as a marketing channel. I would say it will be easier to do so if your products/services appeal to a large, diverse audience. But if you are in a small niche, Twitter might not be the best solution.
Bottom line – Twitter is another marketing channel and requires effort too, this isn’t an easy way to profit. It’s new, but it appears that there has been some valid success. In the end, you really have to test out new marketing channels and compare them to how those you already use are performing. So I wouldn’t write it off, I’d test it!
