For all bloggers out there, you might already know about LinkWithin. You might be using it right now, or you're not. Well, for this post I will be writing about nRelate, another widget but with more features.
Click on Install
Select a product to install. Usually I will choose Related Content.
Choose your blogging platform.
There are 2 setting available here.
a) Registered account - You will be able to use your nrelate partners account to change the settings of your plugin and signing-up for advertising (optional). This includes image size, adverts, caption, etc. I prefer to use this instead as there's a lot of customization option available. Feel free to experimenting by your own.
b) Free (without account) - You will be able to install the plugin without signing up. Follow the steps mentioned. Be informed that you will not be able to change the plugin settings.
Follow the steps shown to add the plugin to your blog. Finish!
