Google AdSense Technical Implementation Guidelines

something most people may have missed on the Google Adsense site

[level80]

If you log in to your Google Adsense account, click on settings and then read tips you should be taken to this page. It contains 10 questions and answers - some of which are quite often asked on this forum - for example question seven:-

Why am I not displaying relevant ads on my web pages?

Also if you click on Help in the top right hand corner you can click on a link to optimization tips. This page shows you how to "maximize your AdSense earnings potential by following these tips from the AdSense team and AdSense publishers". What is very interesting to me anyway is that they recommend the following regarding colour palettes:-

The background color of the ad the same as or similar to the background color of your page.
The border of the ad a color that is prominent on your page.
The title of the ad a color that is similar to the text on your page.
The URL of the ad a color similar to other link colors on your page.

This seems to have been added when the Terms/FAQ/policies were updated on October 16th.

Unless of course you want to make sure that people still know that the link is an ad.
