Good information from @johnmu about how sites are evaluated for Google Discover & Search quality-wise. For evaluating bigger quality changes over time, it can take several months for G to understand a site better. One month is probably not enough time:

@johnmu went on to explain that Google will focus on content based on your site. E.g. if you are news site publishing content all the time, then G will focus on that newer content for indexing. And if you have multiple sections, then Google needs to balance those quality-wise...

John also went on to explain that if you are looking at overall quality issues, and have sections with lower-quality content, then G will balance those w/the higher-quality content sections to understand *overall quality*. Me: Don't ignore lower-quality sections, handle them.

And remember, Discover's documentation explains that Google wants to surface content from sites that have *many individual pages that demonstrate expertise, authoritativeness and trustworthiness (E-A-T)*. So IMO, be careful if you have lower-quality content indexed.
