Is there any disadvantage of adding Google Translate button in a website according Search engine??

Creo que es conveniente el agregar el translate de google, pues te beneficia en algunos aspectos y lo practico que es.

So where are all the so called experts in this field... don't see much input...isn't Apsesnse a Business Sharing Centre???

Good point Jp..and my response is NO I don't think it will harm your site. If you have the Google Translator button directly on your website I think Google will appreciatively recognise your site for International Relevance... fine line though will be...who does your website benefit most and your target audience.

Trev, I want to know is there any bad effect (SEO point of view) if I use google translate button?
Will affect my website at the of optimization, Like auto Translator in Multilingual site.

adds dimension and diversity but can be tricky

I Think Need This Many People so it's important of adding Google Translate button.
