Tricks For Improving the CPC, Official From Google

I've just found Tricks To Increase The CPC, Official From Google on Google Adsense Support. To see the trick you can follow steps below =
1. Open Google.com/adsense/support
2. Select the "Optimization Lab "which is at the somewhat lower.
3. Continue to select the menu "Lift the CPC"
4. Continue to select the menu "B. First Ad Unit counts"

B. First Ad Unit Counts

Make sure that the best performing ad unit (highest CTR) is the first in your HTML code to improve your revenue.

• First, you will need to place a DIV tag right below the BODY tag in order to let the browsers know which ad unit goes first in the source code HTML. Note that it doesn't mean that this ad unit will show up first on the page. Here is the code:
  
  <div id=”ad1″>
  Insert your ad code here
  </div>
• Next, insert the CSS code below into the style sheet of your website. Since all sites are different, we recommend that you test attributes (left, right, top, bottom) in order to place your ad unit correctly. Make sure to adjust height/width depending on the ad format.
  
  #ad1 {
  width: 468px;
  height: 60px;
  position: absolute;
  left: 140px;
  right: 0px;
  bottom: 0px;
  top: 350px;
  }
• If you don't use style sheets, you will need to insert the above code into DIV tags between the HEAD tags in the HTML source code.
  
  <style type=”text/css”>
  Insert above css code here
  </style>

For Code Below I put it on blogger.com in the Edit HTML Menu
<div id=”ad1″>
Insert your ad code here
</div>

For Code Below I put it on the template designer menu -> Add CSS
#ad1 {
width: 468px;
height: 60px;
position: absolute;
left: 140px;
right: 0px;
bottom: 0px;
top: 350px;
}

To measure the pixel left, right, bottom & top of the ad unit I use the Add-on "MeasureIt" in Firefox.
For too long pixel, I use 0px .
But the problem while in the Edit HTML blogger.com because it always appear error message = "Open quote is expected for attribute" {1} "associated with an element type" id ""
I'am Not yet tried it in wordpress.

My Question is = What should i do to use this trick successfully on blogger.com ???

I'am very interesting to use this trick because my Ads Unit 3 have highest CPC than other, and my Ads Unit 1 have highest CTR than other. Place of my Ads Unit 3 is on the bottom. Place of my Ads Unit 1 on the top. So i will use this trick to change my Ads Unit 1 become Third in the eyes of a robot adsense. So My Ads Unit 1 will have highest CTR & CPC. See my ads place on = 2.bp.blogspot.com/-Rlg_waNhZ-c/Te7Vkz-nlkI/AAAAAAAAAWk/lH_vih2J-XA/s1600/123.png
