En el día de hoy vamos a ver algunos estilos de buscadores para Blogger, algunos de ellos son realmente espectaculares, así  que empecemos:

Debes tener en cuenta que estos buscadores muestran en sus resultados de búsqueda solo contenido de tu blog y no puedes añadir adsense en ellos.

Hay que recordar que los códigos de los buscadores se agregan en Diseño, Añadir Gadget, HTML/JavaScript.

Geniales buscadores internos para Blogger
