I herd that adding relevent pictures and videos in your web 2s make it look a bit better in googles eyes. Obviously yes the content also has to be relevant, good and unique. My question is can I use the youtube video that I am trying to rank to add it to the article as my "relevant" video? Will this help with my ranking? I will be mannually creating at least 4 web 2.0s so will his look unnatural if all them contain my video as the relevant video embedd?
