Rumors of layoffs at DoubleClick appear to be heating up.

A few weeks ago, reports surfaced that Google, which had just closed its acquisition of DoubleClick, was planning to trim its workforce to avoid any redundancies created by the deal. Now, VentureBeat is reporting that layoffs could begin at DoubleClick as early as tomorrow.

ValleyWag jumped the gun and reported that layoffs at DoubleClick would begin April 1. That didn't happen.

According to VentureBeat's anonymous sources, Google plans to axe middle management types, not the company's sales team. ValleyWag didn't know who Google was likely to cut from the DoubleClick team, but one tipster did report low morale at the company.

All of this news comes at a strange time for Google and DoubleClick. Recently, Attributor, a web content monitoring and analysis platform, and Compete teamed up to figure out the true impact of the deal. It turns out that with the acquisition complete, Google owns both the long tail and the big head of internet advertising, although its lead in the former category is more significant than DoubleClick's lead in the later.  

Meanwhile, debate continues to stir over Google's overall vitality. While Google debunkers insist that a second straight month of poor paid clicks numbers are a sign of a weakening company and soft U.S. economy, the search giant maintains that the data really means its doing a good job of improving relevancy and increasing ROI for advertisers.
