You need to create an efficient search engine that narrows down the research and not the opposite (for both photos and videos). For example if someone is searching for a 40+ short hair brunette there is no need to show all the videos related to brunettes, to the mature women or to the one with short hair. Likewise it's not useful to include blondes, teens etc. Do that (I know it's easier said than done) and I'll stay with you for ever. At the moment the best search engine is found on Nudevista.
