Any person, organization, business, publication etc. who doesn’t believe that women are a viable, valuable presence online needs to get to BlogHer2010 — and fast.

This blogging extravaganza has brought together women from around the country who are not only driving crucial page views but also creating original content across the virtual landscape. Right now I’m pecking out this post from the BlogHer Chevrolet-sponsored “Chill Space”, surrounded by women of all ages furiously typing away, networking and making social media consulting calls. And I mention that sponsorship to drive home (unintentional pun!) the point that while BlogHer sometimes gets pegged for being nothing more than a haven for “mommy bloggers”, this conference has so far been an eye-opening experience to sheer monetary value of women on the Web.

I came to BlogHer to meet fellow lady bloggers and learn from the plethora of workshops and talks. However, I wasn’t expecting the overwhelming brand presence at this venue. And it’s clear that when it comes to figuring out monetizing businesses and brands online, tapping into these extensive female networks are the way to go.

To get an idea of the extent that major brands are shelling out to grab BlogHer attendees eyes, consider this. Proctor & Gamble has constructed a nearly full-sized house inside this Hilton and stuffed it chock full of its household products. We’re talking fake grass, actual appliances and a full kitchen setup. When I strolled by the installation, the “kitchen” counter was filled with BlogHer-ers busily cutting and pasting collages from vintage P&G ads. Why exactly? I don’t know — the PR rep just told me it was “for a good cause”.

But the reason behind it doesn’t really matter from a marketing perspective; the most important thing is that these women are building an experiential connection to this corporation and its myriad brands. On the other end of the exhibit hall attendees were competing in a Hillshire Farms sandwich making contest. And those are just two of the many, many major brands sponsoring and pitching their wares at the conference. To me, that communicates loud and clear that the big players in the business world are slowly but surely cluing into the influential role of women online — and at the checkout counter.

Why should a lady blogger like myself care about all these businesses pouring tons of marketing dollars into this event? Long-term survival online requires monetizing content at the end of the day. Web sites don’t run on sunshine and unicorn dreams, and all the Internet fame in the world means nothing in the long run if there isn’t a sustainable revenue stream somewhere along the way. Witnessing the colorful swirl of branding around me at BlogHer is a reminder that, sadly, monetization is the name of the Internet game — and also a reassurance that if we keep playing hard online, women will win it.
