The Single Best Content Marketing Channel for Your Startup

The single best content marketing channel is email subscriptions powered by Twitter/social media distribution.

Thirty days ago, I began an experiment with this blog to determine whether email, Twitter or RSS would be the better content marketing channel. My goals with RSS, Twitter and email are two: first to maintain a relationship with a reader longer than a single website visit by creating a communication channel and second to use that marketing channel to drive re-engagement.

Below, I’ve analyzed the results and come across some surprising findings. First, RSS subscribers generate more traffic than email subscribers. Second, email readers are much easier to win than RSS readers. Third, email and RSS subscribers tend to be very different audiences and these channels do not cannibalize each other. Fourth, Twitter’s performance on a unit basis pales in comparison to its competition, but makes it up in volume.

Note, the code to perform a web, rss and email analysis is at the bottom of this post, in case you’re interested in analyzing your startup’s content marketing effectiveness.

Email and RSS Conversion Funnels

Email and RSS subscribers open blog posts at roughly equal rates; RSS is a moderate 21% better. But 2.5x more people click through to the website from RSS as from email. When RSS subscribers do come to the website, they browse about half as many pages as email subscribers. Net-net, the average RSS subscriber generates about 25% more page views than an email subscriber.

The most effective content marketing strategy is to combine Twitter’s distribution capacity with email’s conversion rates and broad applicability.

Email RSS Twitter Delta
Open Rate 51% 62% n/a 21% better for RSS
Click through to site 23% 80% 4.5% 250% better for RSS
Page views per visit 2.3 1.2 2.0 91% better for email
Expected Page Views per 100 Subscribers 127 159 9 25% better for RSS
Subscriber Volumes 454 1567 9874 530% better for Twitter

Other Interesting Data Points from the Analysis

The Story in Charts

Traffic is indicated in gray, new subscribers in red and unsubscribers in blue. Email signups are volatile and aren’t tightly coupled to traffic, meaning the blog fails to convert many new visitors driven by large volumes of retweets or HackerNews traffic spikes to subscribers. subscriber_acquisition.png

This chart shows share of traffic by channel. Email has grown from about 0 to 15% in 30 days. RSS is also growing and has reached about 20% of page views. Twitter represents about 23% of traffic. On an average day, about 55 to 60% of traffic is brought to this blog through reader marketing channels. The figures are incredibly volatile, however.
