I've got one main money site and am in the process of building multiple blogs in the same niche. I haven't really done any SEO work on the money site which is now several years old (been getting traffic by other means) But now it's time and I want to make sure I build links the right way. I would like to use one of these services like dripfeedlinks or dripable etc., to slowly and gradually build links, but I've been told not to use those kinds of services to link directly to my money site(s) So where do I begin? What's the recommended process here, taking into consideration that I'd like to outsource all of the link-building, off-page SEO, whether it's to one individual/service or multiple. Step-by step recommendations?
