  Ayman Albarbary: Hey everyone,
  
  I've never thought there's a schema for services, and I am wondering if anyone has used it before. Do you think it would be useful to apply, for example, to a marketing agency website?
  
  Here is the schema link

  Many thanks to all

  Richard Hearne: Depends on what you man by "useful"?
  
  AFAIK Google doesn't support this, so it's not going to make any difference to them.

  Ligatures.Net: It can't hurt you if you do use it, but I am unsure whether it would be useful. I don't know whether Google creates Rich Snippets for services, but if it does or if it will, it is the best way to tip them... ;
