Very Useful 10 WordPress Hacks

On December 13, 2013

Whether it’s WordPress hosting providers, designers, developers and lots other who have been involved with WordPress, every new day, a different useful hack will make a day for all. But what essential, does the hack is just like normal sting of lines or something more. Possibilities are many – really much and more – but unless and until one got the right one at place, nothing makes a complete sense. In this article to bridge the gap, I have collected 10 of very useful WordPress hacks.

#1 How to insert ads every two posts in WordPress

It is said that ads inserted on the content perform better than those on sidebars or footers. Let’s see a quick and easy technique for WordPress to display ads every two posts.

In order to do this, we need to initialize a variable before entering The Loop and, during the iteration through the posts, test if its value is even. We will use the Modulus operator %, which in an operation

#6 Show Adsense Only to Search Engine Visitors

As we all know that regular visitors don’t click on ads, around 90% folks who click on ads are coming from search engines.

Also for fact that Google pays more if your click-through rate (CTR) is higher, Google’s “smart pricing.” Being smart priced means that your click-through rate (CTR) is low and the money you earn per click is divided by between 2 and 10. For example, if a click would normally earn you $1.00, with smart pricing it could earn you as little as $0.10. Painful, isn’t it? Happily, this solution displays your AdSense ads to search engine visitors only, which means more clicks and a higher CTR.

#7 Image Decoration and Optimization Tutorial in WordPress

The reason in-post image decoration is important is because many WordPress sites have large collections of images, but they lack simple image size handling and other basic functionality. We’ve all seen blogs where the images overlap with text, or expand beyond the border of the design.

#8 Show Category Images

I’m going to show you how to add some simple PHP code to your WordPress template and make linked images appear instead of text for your categories in posts. All you need to know is simple PHP, some basic HTML, and how to make your own graphics.
