Review your tag strategy for Tumblr.
Tumblr tags play a huge role in your success on the social media tool, so be sure to take a little time and review your Google Analytics to understand how well your current tagging strategy has been working. Then, look at the Trending Topics on Tumblr to discover new ways you can approach the community.
Using Tumblr tags to boost your followers.
In order to fully understand how to use Tumblr tags to boost your followers, you first have to understand that the Tumblr search works almost exclusively on tags. So if you want to appear in searches, you need to use tags to get noticed, or even included.
So when you post, keep in mind that using seven to twelve relevant tags per post is enough to get noticed on as many searches as possible without looking like you’re spamming (and be careful, Tumblr will ban you for spamming).
It also means that you should be posting to Tumblr a lot, with a variety of tags that’ll saturate as many searches as possible with great content. But remember: Tumblr users are most active on weekends and evenings. Be sure to post your best work when they’re most active.
