In August, Google announced that it was upgrading its category filtering feature for AdSense, and extending the feature into more countries like the US and the UK.

Today, Google announced that they have added two additional improvements to the Competitive Ad Filter. These improvements would be faster filtering and increased filter size. In the past, the Competitive Ad Filter sometimes took up to several hours to block URLs youd entered, says Arlene Lee of Googles Inside AdSense Team. Knowing youve wanted a faster filtering system, were excited to let you know that URLs added to your Competitive Ad Filter are now usually blocked within 30 minutes.
