Slow November for PPC?

Hi guys!

So I’m kinda worried with my products. I launched my campaigns 4 months ago, good sales growth and volume plus a steady decline in ACOS, however… For November? Sales up, impressions up, CTR up BUT my ACOS increased along the CPC plus my CR went down (-4% on avg) ; I was actually going to hit my goal ACOS for November so I wanted to post here if anyone else had a slow month?

I’ve been pretty hard on negatives + cleaning up broad and “research” keywords and with my budgets in hope of hitting my goal for December but overall November was a weird month for me, what about you guys?
