My story is short A manager from a big adult site contacted me some days ago, he is interested to buy spots on my sites for text ad link. His main request is to place hes link on the index only, no categories pages, no pagination pages, only on main page, i think he wants in this way for low outbound link. I'm not very good at SEO or backlink building but I think he is looking for backlink, cause he is interested on long therm deals. A friend of mine already have a deal with him from a year ago. So I have 2 questions: 1. Is safe for my sites if I sell spot for his link? 2. If is safe and he will want to make the deal what price to ask for? Price will be determined by location (upper, middle, lower fold, with text etc.) deal will be for 6 months to 1 year.
