It wasn’t enough to just post high-quality articles on the Foundr blog itself, but it was crazy important that we start getting our posts onto other influential sites as well. Taking our cues from Buffer, we began drastically ramping up our content creation process. Part of that process of guest posting was including as many links as possible back to the Foundr site.
Try different hyperlinks to see what works best for your audience. You might create three different groups and send each link to your home page, product pages, and blog. You might also try CTA links with different wording, or test an email that includes the same link two or three times. The data will tell you what works. Low click rates may mean your emails aren't compelling, or the information isn't useful for that audience.
