beamer add tag

I have this MWE:

```
\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{itemize}[<+->] 
\item blah
\item foo
\end{itemize}
\uncover<3->{
 \footnote{\href{www.google.com}{google}}.
}
\end{frame}

\end{document}
```

I want the footnote to appear after foo but currently it appears right at the start. Instead a stray 1 appears at the third transition.

Beamer footnotes are overlay aware. You can control their appearance via `\footnote<...>{...}`:

```
\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{itemize}[<+->] 
\item blah
\item foo
\end{itemize}
\uncover<3->{%
 \footnote<3->{\href{https://duckduckgo.com}{duckduckgo}}.%
}
\end{frame}

\end{document}
```

If you don't like the footnoterule on the first few overlays, you could use `\only` instead of `\uncover` (however this will influence the position of other elements in the frame, so you might want to use a top aligned frame):


```
\documentclass{beamer}
\begin{document}
\begin{frame}[t]
\begin{itemize}[<+->] 
\item blah
\item foo
\end{itemize}
\only<3->{%
 \footnote{\href{https://duckduckgo.com}{duckduckgo}}.%
}
\end{frame}

\end{document}
```
