Out adrift in in the vast sea of online content, it’s very easy to suffer from content overload.
“What should I read?”
“Who should I follow?”
“How will I know if their advice is helpful?”
To save you the trouble, we decided to compile a list of our own favorite blogs that we follow!
We’ve previously featured 25 such marketing blogs, but as the post was originally published in 2014, many of the blogs that we’ve featured has either ceased to exist, or have not been updated for a long time.
We’ve decided to give this post a long overdue update.
This new list of blogs were chosen for their thought leadership and/or breathtaking presentation. They’ve helped us gain new perspectives and improved the way we work– and we’re betting you’ll experience the same thing.
This time round, we’ve also sorted them into the different marketing categories, so you can jump straight into the best of the best in the category you want to learn more of. I’ve also extracted their most popular blog posts (using Ahrefs’ Site Explorer) to give a quick headstart on what their blog is like.
(NOTE: If you’re looking for the best ecommerce blogs, you can find them here.)
Without further ado, here are 55 of the best marketing blogs (sorted by categories).
Click on the following links to jump to your relevant topic:
- General Marketing
- Word of Mouth Marketing / Influencer Marketing / Affiliate Marketing
- Content Marketing
- Email Marketing
- Social Media Marketing
- Conversion Rate Optimization (CRO)
- Pay-Per-Click Advertising (PPC)
