I am looking for some advice on how to find pages to advertise on. Do I just search around and find pages under the niche(s) that I am look to advertise about and then contact the people running the pages? Do they advertise alot? Meaning...will they already have a price in mind or will this request for a post about my product/site be weird to them? Is there a place (forum or site) that has people posting their costs to advertise this way? What is the best way in your past experience to make sure I am getting the best return for my money spent in advertising this way? Is this better than using Facebook ads or twitter ads ect...? Sorry for all the questions but I am hoping some of you can help guide me or maybe point me in the direction of a resource to read up on this type of marketing. I know the basics, just obviously not much more. Thanks guys and gals.
