Hi everyone, I have recently started white hat linkbuilding with good initial success. Basically I have submitted spun content to multiple (30-40) Web 2.0 and Article sites in open linkwheel form. Doing this alone has managed to rank my easy keywords sub 50 in google. Basically I'm wondering if submitting new spun content to the same sites under different accounts will continue to have postive results on the SERP's or will I need to branch out the linkbuilding to blog comments etc. instead? Any help would be appreciated as it would save me a heck of a lot of time and effort. Thanks.
