Howdy everyone, Recently I found that many seo buddies don't do Link building but on-page seo. On-page seo is more important than Link building in 2013? It is said that by doing on-page seo only can avoid unnatural links warn by google.Is this true? If so,how can I do on-page seo on e-commerce sites? what's your on-page seo experience? Any one can share with me?
