While Andy's response was helpful, I'm still hoping to hear from a couple people with specific experience in regards to using Tumblr for linkbuilding (good or bad). Keeping this question marked "unanswered" till then.

Thanks for the response, Andy. Since I've already put in some hours on this one (and since it obviously isn't "black hat"), I'll likely still go forward with the idea as an experiment somehow.

However, whether or not it's best to use Tumblr is something I'm still on the fence on. (The benefit would be being able to pass the project to a junior developer on our team to knock out.) But if a Tumblr microsite isn't the best in terms of linkbuilding as it was just a couple years ago, perhaps just a standalone WordPress site would be better for a project like this.

Thanks again,

Zack

Hi Moz Community,

I've recently decided to start a project where I gather 1,000 great examples of something that's searched for often, and am thinking that posting it to a Tumblr site like the following website did could be a great way to pass link equity back to my main site (with a little "site by [my site]" somewhere in the header or footer).

While I was super pumped about this idea today, and have now gathered almost 500 of my examples (mentioned above), I am not seeing link equity passed from this site, even on the non-redirected links here:

http://gothamlogos.tumblr.com/

Anyone have any experience with projects like this? I've checked read the Moz Tumblr and SEO article from a few years ago, which makes it seem like this should be an SEO "win"... But using the Moz Pro account tools, I'm not seeing any of these non-redirect links (ordinary links) giving any value to anyone on this example site.

Thanks so much in advance,

Zack
