These hashtag tools will allow you to use hashtags more effectively.
Tagdef.com will help you find popular #hashtags. You can enter a hashtag term and find out its meaning, date first used and related hashtags (see below).
This also lists what is popular, all time high, new tags and top users. I like to use the popular hashtags to see if my business can relate to any of those. If so, I can add that tag to some of my posts.
Hashtags.org is where you can get deeper analytics of how a certain hashtags were tweeted by the hour in a 24 hour period. This can give you a gauge of what hashtags are popular at certain time of the day.
The other lesson I see here is it can gauge the best time for your type of audience. By the looks of the graph below, if your target audience is a small business, it looks like there is a significant peak in the afternoon and a significant drop in the evening.
This tool is so useful for engaging and finding current content! This is more than an analytics tool. This is an engagement tool. It includes Facebook, Twitter, Instagram, Google+, and Vine. It would be nice to see Pinterest here too. You can see the specific hashtags on all the platforms or choose to see content on Facebook only, Twitter only, etc.
It is easy to engage and share right from Tagboard.com too. This is a must-use for hashtags, content and engaging.
The above hashtag tools are so helpful to improve your social media exposure. A little research time on what hashtags to use can take you far. Be sure to spend some time digging into each before you post that next #hashtag.
