If you’ve been having trouble getting your tour dates to sync up to Google , things should be a little easier for you now.
Google syncs tour dates, releases, bios, and more to the Knowledge Graph panel that comes up when you search for an artist. They also use this data to sync information up to YouTube. Now tour date information will come straight from official artist websites.
To set this up you have to add specific markup to the code of the official website. Sounds complicated, but there are some extremely easy ways to do this.
You can sync tour dates to your website through a third party widget, such as Bandsintown, BandPage, ReverbNation, Songkick, etc. Google will find this information and sync tour dates for you.
