This is because they often occupy the best part of a blog, which is the head or top at the beginning of the content.
These areas are the most visible to anyone visiting the blog and those that have a large number of readers charged more charges for any banner posted on these sites.
AdSense gurus have stated many times that the banners in the header converter not as good as the large rectangular advertising within the upper portion of the article in a blog. People who buy ads want the most visible part of the blog and therefore, banner ads at the top will get a higher price.
To place a banner in the header, you must have a header wide enough to accommodate the flag. So if you intend to place a banner of 728 x 90 pixels, make sure your seat is wide and big enough for that. We must also take into account the logo of your head and take steps to fully display the banner.
As always we started with the addition of a new switch or a div. Just CSS attributes define the banner and set the margins to align correctly. You can skip to declare the width and height, since this will add banners of any size. A simple example will look like.
. ads (float: right; margin-top: 40px; margin-right: 10px;)
Of course, you can set your own preferences, and left floating or have different margins.
Then go to your header.php file and find the ID of the div header image. Usually looks similar to this.
Now that I have found, you must insert the banner code inside that id, which means it must be before the closing div tag. If you put off the closing tag, your banner will not appear or if you do, not inside your head. Like for example if your div id is “head”, you have something like this.

Of course, there will be many more lines in your header.php that is only an approximate guide. While not delete anything and do not forget to close the class labels, everything should be fine. In cases where the banner is not in the right location, you can always return to your style sheet to re-write margin distances. It is trial and error.
