Otimização de sites em inglês (seo), por que você acha que é difícil? O segredo é que você tem poucos recursos e não consegue fazer bom uso de alguns recursos em inglês.
Pode-se dizer que o diretório de marcadores sociais em inglês é a verdadeira força motriz dos motores de busca e é muito eficaz para melhorar a classificação do site e aumentar o peso do site.
Eu forneço mais de 500 sites sociais + bookmarking em inglês que coletei e usei para todos usarem. Um número tão grande de recursos depende principalmente da capacidade de execução de todos.
