Now more than ever it's important to surround yourself with influencers in your industry if you want to succeed online. This is how you build your own following, how you learn about the latest trends and stay up to date, earn more social shares and visibility, build natural links, and more. Even if you don't "know" some of the top online marketers, engaging with them by commenting on posts and learning new tips can be invaluable to your online strategy.

If you're not sure where to start and who to start searching for, it can help to break down some of their expertise into categories and sort out who you should follow that way. Below gives you a starting point with 23 of the top thought leaders for online marketers to get to "know" today:

Search Engine Optimization (SEO)

Rand Fishkin. Wizard of Moz.

It sounds like a "ludicrous" title as Fishkin will tell you, but he is the founder and former CEO of the company, formerly SEOMoz. He is also the man behind the popular "Whiteboard" Friday posts that help to teach SEOs about complicated topics through video and whiteboard examples. He's one of the best when it comes to cracking tough SEO questions and breaking down complicated topics. He built Moz from the ground-up in 2004 as he began posting data reports and creating tools, and it has blown up to be one of the most well respected blogs and SEO tools in the industry.

There is a lot of competition when it comes to thought leaders in the SEO category, but Blumenthals made the list because of his extensive knowledge on local SEO and his ability to stay in that niche and dig deep. He is the owner of the popular blog Understanding Google My Business & Local Search, and what's cool about Blumenthals is the fact that he keeps the blog in-house. In other words, when you want to hear what he has to say about SEO, you can count on his blog covering his writing and thoughts and his writing only. In addition to this blog, he also founded Local U, a conference series to learn more about search marketing, and co-founded, which helps small businesses create a customer feedback and review management strategy.
