Can you clarify whether you are just changing your on-page optimization consistently or if you are actively changing URLs that are being targeted for this term?   From your snippet I see issues right away, but would like to know the answer to my questions before I respond.

Thanks for the time for answer

NO, we do not change ON page elements consistently or even URL, which you describe.

I can't understand about "From your snippet I see issues right away"  can you explain what issues are occurred in snippet.
