Has anyone used a professional link management service? ie - a company who finds relevant recip/inbound links for you on a regular basis and charges you a flat $X pm up to which they will find you X number of PR4 links, Y number of PR5 links etc
They would also monitor the sites linking to you (& the links on your own site) to make sure everything is working as it should be & would deal with all email concerning links.
What are the pros & cons of using such a service? Things to watch out for? How much should one pay?
Have been offered this service but am dubious.... TIA J
