Going to do be doing forum posting for traffic boost and SEO link building, going to manually be posting across 30 forums. For SEO purposes, is it okay to use the same username since I'll be dropping my link in the signature and profile? Any other tips, should I vary the signature or can I just use the same one? Should I vary the keywords, I prefer to just use the brand name of the website, and do other SEO for the main keywords later on. Thanks.
