Not everyone wants to leave a comment, and you don’t know who have read your post without feedback. WP-Clap helps you make your visitors leave simple feedback without type a comment.
WP-Clap will creat a clap area after your post. Just like the comment area, your readers can clap for your post after reading, but they do not need to type anything. You can also use our function in your homepage to show how many claps the posts have, just like how many comments there are.
并不是每个人都会留言，日志冷场现象经常出现。WP-Clap插件允许你的读者在浏览日志后能轻松简单地留下路过的印记，减少冷场现象。
