I'm relatively new to XRumer, and the way I've been using it is linking directly to my website. After reading quite a few articles, it seems that all the pros are saying you need to do tiered links which is: writing legit hand-written articles linking to your website and having XRumer link to those articles, not your website. Can I use XRumer to write Tier I links? Is this true/necessary? Will it help my SEO rank build faster? Or is it just for security? I feel like it would build my SEO results slower. Also, what's PR/PR5/PR6, etc. etc. and SERP and SERPII and all these other common SEO terms? Any help is appreciated, thanks!
