Although there’s not much that can be done to alter your CTR by weekday, I thought I’d throw this table in just because it’s interesting. Sunday seems to be the best performing day, with Friday on the bottom. Why? And why is Tuesday better than Saturday?

I have a theory–and that’s all it is, a theory, so take it with a grain of salt. Friday is low because more people are preparing for their weekend trips and activities, and so they have less time to surf the web. Saturday is low because those same people aren’t home! Sunday is high because they’re back from their activities and want to hang out at home.

Average CTR By Weekday

No one say the best text color for your site without knowing color scheme of your site. But you should know that text color of your ads is very important to make them click. Because visitors should exactly focus on the ad to click ads. One important factor of your ads is text color. According to the bellow figure highest CRT is represent color code of "000001" it is 7.16 % but you should adjust post background color, ads link color, ads background color also to reach that much of CRT.    

Bottom Line: Stick to the blacks with your text color.

Some AdSense publishers performed tests and reported that blending AdSense colors properly with your page will result in a higher CTR. Well, you should already know that a higher CTR means more clicks from your ads, and that translates to higher earnings. In your AdSense setup, you should already be familiar with the tool shown in the screen shot below. It allows you to configure the outputted colors of your ads.

Based on the options provided, you can actually assign colors to the Border, Title, Background, Text and URL.

Not included in the list is the font type used, which is also an important factor in the blending process. Here is a list of recommendations to get you started in customizing the AdSense that appears on your website. 

Now you have some guidance as to how to blend your ads with your website template’s colors. It is sometimes difficult to find out the exact color used by your template. Colors can be configured in Google AdSense using hex format (e.g. #FFFFFF for white color).

Bottom Line: As with borders, if you’re going to use a background different from yourpage background, make it a subtle one. In the case of the odd pinkish color in the top spot, the pages were actually the same color, so it blended well.

There are some good suggestions for picking up a great color scheme for your Google AdSense Ads:

1. The complimentary technique – This would use new colors not currently on the page, but colors chosen to complement the colors that are. You can leave the border hidden and use the complementary colors for all the text, or use those complementary colors in the ad unit’s border and background, as well. 

2. The matching technique – If your logo is green, you might try matching both the border and background of the ad unit to the same green, then use the page background color as the ad unit’s text color. You aren’t introducing new colors, but matching the on-page colors, and this makes the ad unit more noticeable than the blended technique.

Bottom Line: The border stats show pretty clearly that if you’re going to have a border,make it a subtle one.

It’s hard to draw any real meaning from the url color statistics. It appears that the dark gray works best, but it’s hard to say why. It does mask the advertiser url, but then the light grays do that even better yet do not perform as well. Standard blue and somewhat darker blue do very well.

I have to say that I was rather surprised that the standard blue” link color did not receive the highest CTR. A darker shade of blue (#000080), close to navy blue, attracted more attention.

I can’t conclude that links suffer from a kind of “link blindness” similar to banner blindness, since the other non-standard link colors performed worse than the standard blue. So what is it about navy blue that draws attention? Hard to say, but it seems to work!

The dark blue, of course, works best on a white background.

Bottom Line: With the exception of navy blue, avoid non-standard link colors.

The conventional AdSense wisdom says that you background and border colors should be the same (essentially, that there should be no border). That is true in 6 of the top 10 ad formats, but it is not always the case.

One important thing that we learn from these statistics is simply: do not use the default layout!

Bottom Line: Do not use Google AdSense default layout!
