Last month I experimented with basing the charts on links, as measured by Technorati. But I've now decided to go back to my previous method - traffic rankings from Alexa. Why? Well, it's quicker to do, basically. So here we go.

The biggest riser, going up 6 places from 25th to 19th, was Wieden & Kennedy's Welcome To Optimism, a fascinating and candid blog, which this month included their controversial report on the Nokia pitch briefing.

In an exciting new feature on the chart, I've added an ↑ if a blog's traffic has gone up by 20% or more in the past month, and a ↓ if it's gone down by 20%.

Lots of ↓'s, you'll notice.

In fact only one blog bucked the trend and increased its traffic by more than 20% over the month - David Armano's ever-interesting Logic + Emotion.

Is the adblogging boom coming to an end?

UK means UK-based. Ad blog means ad blogs not marketing blogs, so that excludes Gapingvoid. Paul Colman doesn't class Life In The Middle as an ad blog and - in the move that shook the blogosphere - Russell Davies has announced he will no longer blog about advertising, so sadly he's not in either. Also, I'm only counting English language blogs.

If I've missed anyone out, please tell me and I'll put them in next month.
