International Women’s Day is March 8th, so it seemed like the perfect time to recognize some of the fantastic females around the world who are making things happen in the marketing space. Looking for women I’d want to include led me to tons of blogs, social channels, and brands. The good news is, there are tons of people to include, but the challenge is—there are tons to wade through! There are a number of other lists out there, so to make this list a bit different, I did a couple of things:First, I tried to remove anyone that I had already seen on multiple “who to follow” lists. Not because they’re not awesome, but because chances are, you’re already following them, so this is an opportunity to find some new faces. Second, while I am including most Twitter handles in the list, not all of the women on this list are necessarily avid Twitter users. I extend my definition of “follow” to mean that you should check out their blogs, LinkedIn profiles, websites, and to generally keep an eye out for them—they’re doing amazing things.Third, the list spans new faces, industry veterans, people in startups, agencies, big brands, and everything in between. Hopefully it’s a good cross-section with some surprises thrown in!So without further delay, here are 50 women to follow:Amanda DiSilvestro – Amanda is a great source for SEO and online marketing information.
