# Website as a reference

I want to reference a website in a springer paper so when I click on it, it connects to this website. How can I do that?

\RequirePackage{fix-cm}
\documentclass[natbib,twocolumn]{svjour3}          % twocolumn
\smartqed  % flush right qed marks, e.g. at end of proof
\usepackage{graphicx}
\usepackage{graphics}
\usepackage{amsmath}
\usepackage{booktabs,tabularx}% <-- new
\usepackage{ragged2e}% <-- new

\hypersetup{draft}
\begin{document}
\begin{abstract}
results obtained with simulated data are presented and discussed.

\keywords{keyword1 \and keyword1}
% \PACS{PACS code1 \and PACS code2 \and more}

You can use hyperref's built-in commands \url and \href (see below). I've reduced your code to a true MWE, since the important part is hyperref.
