product keywordsIts about product keywords or informative keywords??
Sape links? Are they really that short-term even if I combine some diversity e.g. Web2.0s, wikis, PDFs, SBs, etc.?Its difficult to advise without knowing exactly what your competition may be like. But trial and error may be the way to go for you. Look for services with good feedbacks and reviews.
Thanks. I'll look into this.Made a thread for people in your situation. Hope it helps.
