I've read that CTR is not static and it's based off of GEO and vertical. Is there at least a CTR guideline available on STM that shows what we should be aiming for per GEO?
I'm talking pure CTR and not with added auto redirect scripts that can bring up the CTR but not necessarily bring in more profits.
I'm in this situation myself where I have a camp that's getting ok traffic and XX profitable days but not sure if I'm getting enough click through to justify running it ATM. My average for the last 30 days is around 2.7% CTR with over 3.4mill visits. Here is a screen shot

(My profits are actually more. When I update the price manually for the day it for some reason adds $10-$15 extra?)
Its the 6th and I'm already at 600,000 visits for this month but only made back around $250. Same average CTR of 2.7%. Will defiantly be getting overage charges on
I've seen people post screen shots with 10% and higher CTR with fewer traffic and way more profits. It's what got me curious if I'm somehow leaving a lot of money on the table.
Is there an optimal CTR for each GEO?
Short answer: no
Depends on the campaign, geo and creatives you are using.
CTR is also quite an irrelevant metric as its all about eCPM and Profit! Always work towards increasing both, increasing CTR can help you with that so its a "means to an end"
Old but good (about landers, but much of it also applies to ads): http://stackthatmoney.com/forum/show...y-Don-t-Matter
I also wrote an article about CTR, though it's about banner CTR, it might give you a few tips anyways : https://stmforum.com/forum/showthrea...ttention-to-it
As for your original question, there are certain CTR levels that you could call optimal, but they are specific to certain campaign situations. It's not like there is an optimal LP ctr for Brazil, but there certainly is a range that you could call optimal for adult dating in brazil when using typical chat style banners and buying traffic from traffic junky on the pornhub ntv-a spot. So yeah, every affiliate who runs under specific conditions, by using rather tight targeting options, should be able to give you a rough range to aim for. The problem is, there are so many variables to consider here, that giving you a range for your specific situation might be a problem, as you might be the only one that uses your particular settings and a specific funnel.
Then there is one more factor, as Christoph already mentioned, in many cases CTR means nothing, it's all about the profits. In many cases, the higher the CTR the lower the CVR will be, due to misleading elements on the LP ...
Looking at your numbers, the 1st campaign shows almost 200% ROI, that's an awesome number, so I don't think there is anything wrong with your LPs.
