Why is there a steady decline in my website's direct traffic?

Topic summary

A site owner reports a steady, linear decline in direct traffic and is unsure if it reflects waning popularity or another underlying issue.

They reviewed Google Search Console (GSC) and found many pages marked “Discovered but not currently indexed.” They ask if this indexing status could be contributing to the decline.

Context: GSC is a Google tool for monitoring site performance; “Discovered but not currently indexed” means Google knows the URL but hasn’t added it to the search index.

An attached screenshot appears to illustrate the traffic trend, but specific metrics aren’t provided in the post. The image is central to visualizing the decline.

I’ve had a linear decrease in direct traffic that is concerning to me. Is this just simply a natural lack of popularity in the site or is their something else that is causing this decline? I tried analyzing my GSC for issues and found that a lot of my pages are “Discovered but not currently indexed”. Could this be the issue? I’m kind of at a loss for what is causing this decline and I really need it to stop!
