Of course, it doesn't take a rocket scientist to figure that one out. Some niches are more lucrative then others so advertisers are willing to spend more.
Ya may be right because as per my knowledge CTR not depends on two things 1st is Ads placement and other content. As placement of ads been done at heat map given by google and content is related to ads then you have a high Click Trough Rate
Whatever you mean is true, even though I guess you're talking about CPC and not CTR, but even talking about CTR yes some niches generate more CTR than others for the exact same ad placement.
i'm not sure, but from my knowledge if we talk about CTR it is likely influenced by your ads placement, colour, etc. and the CPC related to the niche of your content :cmiiw:
I'm not sure if you mean CTR or CPC.. CTR changes by the site design, ad placement, etc. If you mean CPC then of course it is determined by the niche. If you are curious as to what the CPC is for a certain niche you can go here and check. Type in the keyword you're searching for and find out the amount that advertisers will pay for that keyword. Put something like $10.00 in the max CPC box and leave the Daily Budget box blank. Remember that as a publisher you will be making about 2/3 of what is there (For example, if the tool shows $1.00, you will earn $0.66 per click). Just search around and you can see the differences in CPC for different niches. For example, "payday loans" has a CPC of over $4.00 while "Bollywood Actors" has a CPC of less than $0.80. So, as you can obviously see, niche definitely changes how much you will earn. If you truly meant CTR, though (and not CPC), I would have to say that niche doesn't matter nearly as much as ad placement and design.
Well that would depend on the website template, the site topic and the template. All these factors play an increasing role on the CTR you are to receive.
Yah, it is true some niche like business, template, health give you high amount instead of other niche.
I search it on web . Many people though Niche is better . But still there is few people thought it does not ...
