Random Post Iframe Widget For Blogger

After a long time I am back with a new random posts widget for you. This is a simple random post widget but there are some new features. This widget has a simple coding and you have a small code for it unlike the old random post widget which had a long code and slowed your blog loading.

The source code of this widget is hosted on github. Github is a fast hosting so I chose it, although you can store it on any free or your paid hosting. The benefit of hosting source code and running this widget is you get rid of long codes and the other benefit is you can put this random post widget in the form of an iframe anywhere in the blog. You can just put the small iframe in between the posts, in sidebar in footbar and anywhere in the blog.

So this widget will not only speed up your blog but also you can engage your visitors for a blog time because in between the posts your visitor will be seeing older posts which if got his interest you will double up your blog traffic.

Whenever i create a post about widgets i am always focused on traffic, site speed and look of the blog because all these matters alot.

So here in this post I will share iframe code of this innovative widget and also source code for those who want to have their own stored widget or they may want to modify the code.

In my opinion there is no need of modifications as it is already best.

Step 5: Save and publish your post.

If you want to have better look, you may use CSS. I suggest you to put the random posts wiget 2-3 times in long posts and 1 time in short post.

Try putting the iframe after completing your post otherwise you may put random post widget in wrong place because in HTML its not easy to find the exact location. Try to use CTRL+F to find the sentences in the HTML Editor and then put the code below or above.

Don't break any </div> at the time of putting the iframe, it will result in disappearance of whole post or the content may be irregular.

Use <br/> for space above and below iframe.

If you have any questions you can ask me. I hope you liked the post, try to share it please.

Thanks for visiting 101Helper.
