I test a lot of different methods for getting people to sign up to my newsletter.

I've tried things like:
* Scaring them with the upcoming April 21 mobile algorithm update at Google.
* "Act now, limited time only" stuff
* 30 day free trial

But I think the thing that worked the best was offering a free email series. I did one called "Learn Facebook in 15 minutes a week."

Then I just sent them an automated tip (I use MailChimp) once a week.

I got about a 30% conversion rate on that offer. That means if I can get 3 people to come to the page, 1 of them will sign up.

I think people liked this offer because it seemed doable to them. They could spare 15 minutes a week.
