Recently I discovered Google Best Practices newsletter.
Unlike the majority of people out there, I enjoy receiving emails (of course only if they provide some value).
Google Best Practices Newsletter
For that sake, Google’s Best Practices newsletter is a good example. They send bite-sized short emails that anyone can digest in less than 5 minutes.
These emails provide valuable insights on AdWords official paid search marketing tips, checklists, and videos.
Oh, by the way, they have a YouTube channel with lots of playlists too.
