Just two weeks after launch, Facebook is taking hashtags to the next level by rolling out related searches and mobile support.

Earlier this month, the social network made hashtags clickable in status updates published from both personal profiles and brand Pages. It also made them searchable, so members can bring up a stream of mentions.

Now when an individual clicks on or searches for a hashtag, the results page will show other hashtags often posted at the same time. For example, if someone searches #equality, he or she will also see #lgbt and #pride. By analyzing which hashtags are frequently posted together, Facebook is encouraging the discovery of similar conversations.

Additionally, there was no mobile support at the time of launch, and although Facebook’s iOS and Android apps still don’t work with hashtags, its mobile site m.facebook.com does. Now anyone with a mobile browser can tap into hashtags on the social network.

So far, it looks like hashtags have been a hit among marketers. SimplyMeasured found that 56 percent of the top 100 brands have posted a Facebook update that contained a hashtag, and nearly 40 percent have posted multiple hashtagged posts. Continuing to expand mobile support would certainly be a smart move for Facebook.
