I've always had about 100% increase in organic traffic from Google search. But since July (after the core update), my traffic has been on a slow but steady decline, month after month. Each month is worse than the previous one.

I assumed after a while it'll improve by itself because I keep dropping good content. But now, it's beginning to worry me.

It is also important to mention that I don't have any manual action notification in my search console.

Has anyone experienced this before? Can you recommend a solution?
