Going back to a news bit that was came out the other day revolving around the fact that Google seemed to say that asking for links was unnatural, Google has come forward to clarify themselves. Since a post on its Portuguese webmaster blog suggested that asking for links would potentially put you at risk of penalty, Google has said that the answer is “no,” you won’t be at risk of a penalty, as long as you ask for links in the right way
The Portuguese post drew a lot of attention from the SEO community, since it was specifically stated that webmasters shouldn’t be asking for links. It was Google’s Diogo Botelho, who wrote, “não compre, venda, troque ou peça links,” which translates to “do not buy, sell, exchange or ask for links.”
Back in February of this year, John Mueller of Google had said something simialr, saying that webmaster should avoid link building because it is unnatural.
When the news originally broke on Search Engine Land, Google finally got in touch several hours after the news went live and clarified that the post has been altered to say that you cannot:
Buy, sell or ask for links that may violate our linking webmaster guidelines.
