Hello Fellows, What are the current link building practices which are safe and liked by Google? I guess one example if Guest Posting/Blogging? what else? And what should be the keyword ratio among your in-bound links? I'm planning to launch some Clickbank affiliate sites? Any help regarding it would be highly appreciated. Finally can anyone please let me know how to find whether a keyword/niche is competitive or not. Definitely I don't want to choose competitive niche and want to rank quicker. Thanks!
