Yahoo is reaching out to smaller advertisers (as Google has done) - by eliminating its $20 minimum monthly spend for sponsored search, writes ClickZ, pointing out that the move comes on the heels of Yahoo's having wooed smaller publishers with the launch of its Yahoo Publisher Network in August. The move will likely make Yahoo Search more attractive to small advertisers and those who want to run one-time or seasonal campaigns.

"Ultimately, we are focusing our efforts on making advertising with us as easy and as rewarding as possible, for both our current advertisers as well prospective advertisers. This is just one small step in that direction," a Yahoo spokesperson told ClickZ.

Google, which has welcomed small advertisers and publishers, last week posted record third-quarter revenues of $1.6 billion.
