2017 is fast approaching--and if you're looking to learn something new or expand upon your existing knowledge of the marketing world, this is the place for you.

Podcasts are an amazing way to condense and pack a wealth of knowledge into a short space of time. And the best part? You can download or stream these on-the-go.

Think of it this way: The vast majority of us spend hours commuting to and from work. That's valuable time that you should be leveraging.

Here are twelve marketing podcasts that I personally listen to every week to improve my knowledge, hone my skills and keep my mind sharp:

1. #AskGaryVee

If you haven't heard of Gary Vaynerchuk, you've probably been living under a rock. Gary's "podcast" is great for visual learners. He streams each episode on YouTube and typically spends 15 to 30 minutes answering and debating questions. You can Tweet him by using #AskGaryVee, and your question may be featured on the next episode.

2. Louder Than Words

John Bonini's podcast is always entertaining because he interviews such an eclectic mix of successful people, from entrepreneurs to CEO's to creatives. This is your go-to podcast if you're looking to learn from the triumphs (and failures) of some really interesting people.

3. Copyblogger FM

Copyblogger has been going for more than a decade now, and their podcast section is great if you're looking to understand how you can fuse copywriting and marketing to optimize for success. Remember, the digital world is now driven by content. Become a pro so you can learn how to write genuine, authentic and persuasive copy that moves your customers towards a pre-identified action.

4. Duct Tape Marketing

The guys at Duct Tape Marketing run a really useful podcast for business owners looking to market and scale their business. Whether you're a seasoned marketing pro or a fresh-faced beginner, this podcast teaches you how to attract and convert leads, improve your social presence and make sure your website is performing at an optimum level.

5. SEO 101

I can't tell you how useful this podcast is for beginners in the SEO space. If you run a business or have any type of digital presence whatsoever, then the truth is you need to understand how SEO works. You don't need to be a technical wizard, either. This one is a great watch for newbies that don't want to feel overwhelmed.

6. Marketing Over Coffee

Hosts John Wall and Christopher Penn do exactly what it says on the tin. Every week, the duo records a rapid-fire, highly engaging podcast over a roast at a local coffee shop. It's a great, quick way to stay up-to-date with social networks, SEO, copywriting, email marketing, as well as "old school" offline marketing campaigns.

7. Edge of the Web Marketing

Edge of the Web is a weekly, hour long podcast that covers a ton of areas within digital marketing. Looking to brush up or wrap your head around website lead generation, SEO, search engine marketing, social media or just general internet marketing news? Then this is the place for you.

8. PNR: This Old Marketing

Hosts Joe Pulizzi and Robert Rose cut through the crap and really show you how to perfect your content marketing strategies. These two gurus discuss how and why you should tell stories to attract and retain customers, and cover three or four stories in the news that showcase content marketing in action. A great actionable, results-focused podcast.

9. Social Media Marketing Happy Hour

This energetic, fun and uplifting podcast is designed for network marketers, small business owners, entrepreneurs, and anyone who's looking to grind and leverage the power of social media. Each episode is a quick, snappy 15-minutes, but it's packed with insight and nuggets to help you maximize platforms like Facebook, Twitter and Instagram.

10. Marketing Smarts Podcast

If you're aspiring to be a savvy marketer, look no further. This weekly podcast features in-depth interviews with smart marketers from all walks of life. This podcast is very practical and results-focused, so you'll walk away with real insights and advice to put to work right away.

11. The 5 Minute Marketing Podcast

Yes, you read that right. If you're in need of a quick tip, this series is jam-packed with practical strategies and advice to keep you performing at a peak level. It's also hard to say no when you can easily find five minutes per day to pick up some new knowledge.

12. Getting Goosebumps

Shameless self-promotion? Maybe. But if you want to learn how the power of storytelling can unlock some remarkable changes within your business and your marketing strategy, then my podcast might be the one for you. Each week, I interview a range of figures, from HubSpot CEO Brian Halligan, to marketing guru Seth Godin, to Charity Water CEO Scott Harrison.
