default latex package does not contain much capabilities for creating hyperlinks. I recommend to use the hyperref package.

\usepackage{hyperref} then you might change several default values.

\hypersetup{
    unicode=false,          % non-Latin characters in Acrobat’s
    colorlinks=true,       % false: boxed links; true: colored links
    linkcolor=red,          % color of internal links
    citecolor=green,        % color of links to bibliography
    filecolor=magenta,      % color of file links
    urlcolor=blue           % color of external links
}

Latex is a wonderful tool for research publications. There are enough resources on latex and this post shares some tips in formatting your paper to comply with IEEE conference proceedings.

Now a days PDF is the accepted format for a conference. Main issue in creating PDF is, if fonts are not "embedded" (included in the PDF document itself) then it may not print correctly. This will be particularly true when the proceedings are printed, the font you used may not available in thier printers (typically contain only the basic fonts required) resulting in following issues.

Occasional characters may be wrong (e.g. "£" instead of "fi")
Some characters may be missing (e.g. mathmatical symbols)
The paper will show "blocky" low quality characters when displayed on the screen or printed.
