Un problema che spesso hanno molti siti di qualità in nicchie altamente competitive è l’attacco da parte degli spammer attraverso backlinks provenienti da siti di bassissima qualità, siti spam, per adulti o directory a pagamento.
Sebbene questo attacco non dovrebbe teoricamente preoccupare i webmaster, quello che succede in pratica è che spesso Google dà una certa rilevanza a questi link e pensa che l’azione sia stata perpetuata dal webmaster al fine ottenere un vantaggio in termini di posizionamento.
I due maggiori siti che seguo, in nicchie diverse, sono stati oggetto di questo tipo di attacco e, all’interno di Google Webmaster Tools, sono stati recapitati più messaggi autoesplicativi: “Unnatural inbound links”.
We've detected that some of the links pointing to your site are using techniques outside Google's Webmaster Guidelines.
We don't want to put any trust in links that are artificial or unnatural. We recommend removing any unnatural links to your site. However, we do realize that some links are outside of your control. As a result, for this specific incident we are taking very targeted action on the unnatural links instead of your site as a whole. If you are able to remove any of the links, please submit a reconsideration request, including the actions that you took.
