I have three websites, two in the same niche (lets say jewellery) and the other one in a different niche (lets say hand bags).I have adsense ads on my "handbags" site.I haven't monetized the other two. Can I add an image link from my two (non monetized) jewellery sites to my "handbags" site? I mean like an advertisement ? (since women who are interested in jewellery might also be interested in handbags as well) Is that against Adsense TOS ?
