Thanks for your extensive explanation! That helps a lot. I too noticed the differences in CPC, even between men / women from the same region?
I'm gonna test more and more, looking into your advises. You're gonna hear from me on Steem.Chat!
Keep in touch @moataz
You're very welcome @steve-speaks and I'm glad I could help a bit. I haven't done any gender based testing but it would be worth it I believe.
Looking forward to talk to you :)
