Hi i got 22 web 2 sites which i created for one site, all with unique high quality content. Can i use those properties to start ranking another site of mine in same niche or do i need to create fresh web 2 sites for them? All web 2 sites got links from 2-3 sources like profile links, bookmarks etc. Please share you experience on what works better for you, existing web 2 sites or creating fresh ones? thanks.
