$25 per campaign will net me over 300 clicks on GDN in one niche and 150 in the other? I used it as a starting point.
I should also mention, I normally launch 10 campaigns at once. I've found that drilling into specific bid types on GDN yields the cheapest results with volume for me.
300 clicks at $25 dollars is about 8 cents a click. Now, let me drill this down.
You are probably talking about gaming niche and manga traffic. (not 100% sure, but most likely, sorry if I outted your traffic source)
If it is manga traffic, we are talking about over 10 million impressions a day type of traffic. If not, then at 8 cent per click, the volume has to be somewhat huge.
300 clicks a day won't cut it for 8cent a click, huge volume niche (gaming). If we are talking about 30+ cent a click, then $25 dollars won't do anything.
