Add “Emoting” To WordPress with Emo Vote
There are plenty of plugins that let your visitors vote on your posts. A positive or negative vote is quite vague and does not give you information on how your visitors actually feel about your posts. That’s where “emoting” comes into play. Instead of asking visitors to give posts a thumb-up or down, you can ask them to tell you how they feel after reading your posts. Emo Vote is just the plugin for that. It lets you define custom fields and gathers useful information from your visitors.
You are in control of what emotions you want your fields to show. Your visitors can get up to 5 options when it comes to choosing the emotion they feel after reading your posts. If people feel too bored or OK about your posts, you may have some work to do.
Once you have installed the plugin, you want to add the appropriate code right before your comment template (or anywhere else you want it to show up):
Emo Vote can give you yet another way to get some feedback from your visitors. If you are not asking what your visitors feel about your work, you are never going to improve your work.
Overall, this is a very flexible plugin that can be customized to gather actionable information per each post. You can use custom fields to customize questions per each post. Emo Vote does what it promises, and it’s free.
