SKAGs in BW niche

Hello!

Did anyone use SKAGs (single keyword ad groups) in Black Hat Google Ads campaigns? How did they perform in your cases - did you increase your sales/ROI/EPC thanks to them? I was running GAds campaign with mediocre results (1 campaign, 1 ad group, 3 ad texts and 400+ kw) and I had ~0,13$ EPC on USA. Now I changed to 1 campaign, 21 ad groups, each one has only 1 keyword as broad modifier, exact and phrase and I see my CTR and amount of clicks are way higher, but this traffic doesn't convert well (decrease to 0,06$ EPC on USA). Did I do something wrong? I chose the best 21 keywords that brought 95% of traffic on the old campaign and LPs remains the same. It's been only 2 days since I changed that so it might be too early to judge, but I am a little bit worried. Hope you can help me understand it just a little bit

I use only SKAG's, the cpc is way lower, you done it the right way.

Click to expand...

Thanks for the answer! I have a question - how long do it take to lower CPC using SKAGs? I've been running this campaign for 8 days now, I see growth in clicks/views/CTR, but EPC for now stays the same (about 0,046$) and it is the same as I had on my previous non-SKAGs campaign. I wonder when, if at all, it will start to decrease. Or maybe I should lower it manually (I am from Poland so I have 0,18PLN CPC, so I can go down 1/4 of US cent each time).
