Today, we’re launching support for the schema.org markup for organization logos, a way to connect your site with an iconic image. We want you to be able to specify which image we use as your logo in Google search results.

Using schema.org Organization markup, you can indicate to our algorithms the location of your preferred logo. For example, a business whose homepage is Example Domain can add the following markup using visible on-page elements on their homepage:

[PLAIN]< div itemscope itemtype="http://schema.org/Organization">
  < a itemprop="url" href="http://www.example.com/">Home</a>
  < img itemprop="logo" src="http://www.example.com/logo.png" />
< /div>[/PLAIN]

{note: spaces added in tags for display purposes}

This example indicates to Google that this image is designated as the organization’s logo image for the homepage also included in the markup, and, where possible, may be used in Google search results. Markup like this is a strong signal to our algorithms to show this image in preference over others, for example when we show Knowledge Graph on the right hand side based on users’ queries.

Thanks very much. This is probably the most important immediate-impact announcement of this so-far very busy week.

Unfortunately they didn't provide much details on what the recommended dimensions and file format of the logo are.
