Hi guys, I've posted here before and gotten some good tips, but I'm back looking for some ideas for new ad placements on my nature photography site JS Nature Photos ( http://photos.jstechs.com). I currently have link units on my detail pages such as here ( http://photos.jstechs.com/Trees_Plants_Flowers/254-Sunlit_Leaves.html ), and on the category pages like this one ( http://photos.jstechs.com/Mountains/ ). I'm doing fairly well with it, drawing $10 - $20 per day, but I'm looking for any suggestions on new or better ad placements, because my adsense has been decreasing for a while now. Any ideas are very welcome. Thanks, John
