If your main goal is increasing email subscribers, then one of the first things you might consider doing is optimizing your top blog posts for subscriptions. This isn't super time-consuming and can give you a large boost of subscriptions that'll compound over time. Why? Because your top blog posts might be garnering a lot more traffic (from organic search and other sources) than your average blog post, and you can reap the benefits of that traffic by adding subscription CTAs -- if that's your main goal. Back in 2012, we were able to boost our newsletter subscribers by 128% in just three months' time. How? We simply added a new checkbox field to all our landing page forms so people could subscribe to our blog with just one click. In other words, when people filled out a form on a HubSpot landing page to get one of our gated offers (like an ebook), they could also opt in to receive emails about new content on the HubSpot Blog.
Key Takeaways:
- If your main goal is increasing email subscribers, then one of the first things you might consider doing is optimizing your top blog posts for subscriptions.
- Adding opt-in check boxes on your landing pages is an easy way to capture more subscribers
- One way to encourage subscription is to provide something extra for people who sign up for your emails
