Optimizing clicks and getting users to add your site as a Google Preferred Source?

With the global rollout of Google Preferred Sources, publishers have a new opportunity to strengthen their visibility in Search. Users can now choose the websites they trust, and those sites are more likely to appear intheir feed. Google also provides publishers with resources to encourage readers to add their site as a Preferred Source.

Are you actively promoting your site as a Google Preferred Source? How?

just added the "add as preferred source" button via google's deeplink format, doesn't move the needle yet but it's free and takes 5 min to set up

I have not focused on promoting it directly yet. My priority has been building trust with returning visitors by publishing useful content consistently. If people find the site valuable then they are much more liekly to choose it as a preferred source without needing much encouragement.

I'd focus on building a loyal audience first if people keep coming back they're much more likely to choose your site as a preferred source
