Those who make a decent living from AdSense know the importance of using custom and URL channels to track the performance of their websites. You never know when your earnings spike or drop dramatically. You won’t be able to find out what’s happening unless you are using the right channel structure. Going used to limit the number of custom/URL channels to 200. Google has increased that limit to 500 custom channels per product and 500 URL channels for AdSense for content.

To date, you’ve been limited to a total of 200 custom and URL channels, and many of you have asked for more. That’s why today, we’re very excited to announce that we’ve raised this limit to 500 custom channels per product, and 500 URL channels for AdSense for content.

The change makes it easier for AdSense professionals to take their testing processes to the next level. Channels can be used to track direct advertisers as well. As you can tell, making money from AdSense involves more than just slapping ads on pages. This new enhancement should help.
