Google announced Monday that they will start accepting and displaying advertisements from qualified third-party advertisers in addition to the present setup of their Adsense program.

By introducing it, Google Adsense Publisher will have more variety of ads and spot to display on their Adsense monetized sites to earn money.

However, on its initial release, only English ads are accepted in the program. According to Google, by accepting third-party ads, it can attract a greater variety of advertising on the Google content network, which will result over time in increased revenue for publishers and more relevant advertising for end users.

In form, if an adsense publisher are displaying Adsense image ads or flash they will now be able to receive third-party advertisements from the following ad vendors.Advertiser ad servers: DoubleClick (DFA), Mediaplex
Rich media agencies: DoubleClick Rich Media, Eyeblaster, EyeWonder, Interpolls, PointRoll, Unicast
Research firms: Dynamic Logic, IAG Research, InsightExpress, Factor TG

Remember image ads are available in the following formats only and you can switch to these ad unit sizes to take full advantage of these third party ads

leaderboard (728×90)
banner (468×60)
skyscraper (120×600)
square (250×250)
small square (200×200)
medium rectangle (300×250)
large rectangle (336×280)
wide skyscraper (160×600)

Google added that if Adsense publishers chooses to allow third-party ads on your site, (where instead of text only it can be in text/image format) they should update their privacy policy to inform your visitors that third-party vendors may serve ads on your site.

“You’ll continue to have full control over which ads appear on your site with tools like competitive ad filtering and the Ad Review Center. Also, only advertisers with whom we have proven relationships and who’ve clearly demonstrated commitments to our quality standards may participate in this program. Our policies governing ad content and formatting remain unchanged,” Google adds.

This is a good development with Google ad program because there will be little need for adsense publishers to apply for other ad programs to supplement their income, since sooner if not now, those big ad companies that display the same services will be shown in Adsense ads and hopefully more earnings for site owners considering there are more choices for ads to be displayed on their site(s).
