You can guarantee that Google knows that this type of contextual education is a key step in continuous onboarding. The simple takeaways (with complex data backed reasons) are observable in these recent Tips, Tours and Popups in Gmail, Calendar, Youtube and Google Docs.
The Google Best Practices for tips are:
- targeted at users
- has a predictable design and colour that won’t confuse users.
- doesn’t have any flashy colour schemes buttons or widgets that distracts from the education mission
- doesn’t use more buttons necessary than is needed for the job
- buttons look like links (presumably to simplify render on a broad range of devices)
- allow the user to engage with the tip or to easily dismiss
- their response is captured and measured.
There is also examples in Google Photos, Google Assistant and several other products that also use the blue contextual tip – look out for them the next time you are using their products!
