    I have been surfing online more than 2 hours today,
    yet I never found any interesting article like yours.
    It’s pretty worth enough for me. In my opinion, if all website
    owners and bloggers made good content as you did, the web
    will be much more useful than ever before.

    Thanks for sharing such useful information . I was currently building the website in WordPress and asked developers to do add this functionality. However, they hadn’t any idea about the link clocking. After reading your article, I forwarded the same link to them and they installed the plugin. Initially, I had to explore the link, but now it is working fine.
