Hello! I have a combobox and a Javascript as follow: <select onchange="document.location = this.value;"> <option value="/a">a</option> <option value="/b">b</option> <option value="/c">c</option> </select> It seems that Google's bot is following that JS links and it is impossible with this code to add a rel="nofollow" attribute-value. What do you guys suggest me to avoid Google and other bots follow the links contained in the combobox? Thank you!
