Earlier this month, we reported that Google now allows you to check Video Sitemap errors right in Webmaster Tools! "Video Sitemaps help us to better crawl and extract information about your videos, so we can appropriately feature them in search results. Totally new to Video Sitemaps? Otherwise, take a look at this new Labs feature in Webmaster Tools," informs Google.
It's a new Labs feature to signal issues in your Video Sitemap such as:
- URLs disallowed by robots.txt
- Thumbnail size errors (160x120px is ideal. Anything smaller than 90x50 will be rejected.)
