Contrary to what everyone is saying. It depends on what network you join, what perks they give you and how close to them you work. When I was with TGN, they asked me to host a show for them. Because of this I was bringing in 50 subs a day and they ALL came from TGN. Now if I just got partnered and did nothing else. No it wouldn't have helped "minus better search results". I developed shows that helped our partners on a regular basis and gave viewership/subs to them. "now that i'm gone those shows are gone" but still.
Also some networks help with networking opportunities and help point you in the direction of more views. I am now with N4Gtv and a lot of opportunities have opened up for me. Now if I just partnered with them and nothing else then their spotlights would help and better search results but again it's about working with them collaborating and being a "partner".
Being a partner means you are not in this alone, you have some one to work with and someone to help you. If you do nothing but update your banner. Nothing will come out of it. Keep this in mind.
