If i have 1 website, would hiring 2 separate SEO companies to bring up my website on Google work better than just having 1 company handling my website? Or is this practice dangerous/not recommended? Does it get my ranking up faster? Or does it get more SEO work done in a shorter period of time (due to more man power?)? I was thinking in those lines, but please correct me if i am wrong.
Can someone experienced list advantages/disadvantages of doing this?
Costs are not an issue in this scenario.
