Question

My Cost of Conversion went from an average of £15 up to £93 yesterday. Have anyone else experienced this, is this a glitch with Google?  

Answer 1

A glitch. no i very, very much doubt it. its one day, shit happens.

So how is it possible to have such a huge jump overnight?

@lin74 a thousands reasons. you need to look for trends. even at a high level, is cpc higher, is cvr low. give it a couple of days and check impr share, is the market more competive. then outside of google, has you site, product, service changed. SO many questions.

For sure, but nothing happens over night so quickly, without it being a bug or something else. I have had a consistent CpC for several months, now all of a sudden it jumps hundreds of percent.

What i would say is that if you get <10 conv per day, it would not even concern me. if you get > 30 convs per day and then would wait for more data and analyse the shit out of it.

30+ conversions per day

---

Yea ill keep analysing, thanks

---

@lin74 so has your cpc increased or cvr dropped?  

---

CpC same, CvR dropped

---

Woah there. cpc is cost per click. cpa is cost per acquisition (conversion)

---

Ah ok, conversion rate dropped to the floor, cpa through the roof
