A: Yes. Definitely. Right now. Because that’s where everyone else is.

If your brand needs or has a blog (good idea*) - there are a plethora of platforms to choose from to host it: Wordpress, Blogger, Posterous, Typepad, etc…Tumblr is your best bet though if you can provide fast-paced, informal content that’s full of photos, quotes, .gifts, videos, and all around interesting, shareable content that’s unique to your brand. The key to being successful on Tumblr is knowing that Tumblr’ers are visual creatures - so leverage all that you can to catch their attention.

Why Tumblr?

It’s where the masses are.
It’s one of the fastest growing blogging platforms in the world with 90 million unique visits per month with an enormous international audience made up of an (utterly close) equal male/female ratio (see inforgraphic). If you know your target audience uses social media - then a hefty majority of them most likely uses Tumblr too (so you should too).

It’s built for social sharing.
The biggest perk of Tumblr is its reblogging community with a built-in dashboard that creates an automatic streamlined feed of blogs that you choose to follow (similar to Twitter).

This is genius on a few levels -
(1) If you provide creative, share-worthy content, then its likely that someone will reblog your entry and open another door for a new set of audiences to explore your site.
(2) Your readers won’t have to go out of their way to your custom domain website every time they want to read your blog. Instead, they can see your content straight from their Tumblr dashboard where they already spend so much of their time anyway.
(3) Tumblr, like all social media platforms, is built for a two-way street where you can interact with your followers and gain credibility and influence via private messages, likes, comments and reblogging.

It’s simple.
Tumblr catapulted and is the mecca of micro-blogging: short succinct entries, often visually focused and easy on the eyes. It’s also extremely simple to publish content - from text, to photo, to video. Take advantage of all three.

(Notes) If you already have a blog off of your domain website, then use Tumblr to publish snippets of your entries, and re-direct your followers to your main blog. You can also just use Tumblr separately from your main blog to purely share photos/links (ie. Bergdorf Goodman). Also don’t forget to take advantage of #hashtagging - make it easy for people to find your content.
