Emailing is a blog sent directly to your prospect.
Everyone knows that they should be blogging
For better SEO, right? ¯\_(ツ)_/¯
But there’s a reason why you can’t get yourself to do it consistently.
Because a blog inherently sits on your website
Waiting for your prospect to find it
Like a bump on a log
Here’s the thing:
Email serves the same purpose as a blog
And if you archive them on a landing page on your website
Google gives you tremendous SEO credit
Even wordpress will still call your email archive page a blog page
The difference being
While blogs are lazy couch potatoes that sit back and wait to be found
Emails bring the value you offer directly to your prospect
And allow you to build your very own pool of prospects
That can talk back by hitting the most powerful button in your marketing funnel:
The Reply Button

P.S. Having a consistent email newsletter also allows you to promote the one part of your website that lets you keep in touch with your prospect:
