That's bad. Very low CTR would deliver very low earning for you. You can improve it through fixing ad placements, templates, and color blend.
it is low, then again, certain niche will have around 1% CTR. all depends on what kind of site you have and what type of site layout and ad placement you have
I would politely point out that discussing CTR is against Google's T&C's - Be aware as I guess they monitor this forum. Be silly to get banned from adsense from talking about your CTR, google seeing your post and visiting your site via your signature....
why do we keep getting all these is it good, is it bad CTR still? There's no "average" or "standard". Every site is different with different traffic, niche, content etc If you got 100 million UVs a day and 1% clicks them, that's still good in my book
