Google has updated its documentation for the markup for logos. Now, among the admissible image formats, in addition to .jpg, .png, .gif and .svg, also appears .webp.
The document has been updated on 15 June. In just a few days before Google employee Gary Ilsh published a post on Twitter, where he asked webmasters to share examples of logos .webp-format using structured data markup.
According Ilsha, he spent 10 billion search documents, but did not find anything.
To discuss and joined John Mueller, who also called for webmasters to share examples, if they want to .webp became one of the supported formats.
Ultimately, .webp was added to the documentation for the markup for logos.
Note that WebP - is an image compression format lossy and lossless quality offered by Google in 2010.
