Most links use a standard HREF format, which Google has no problem understanding. However, if you use JavaScript code to create your links, Google may not be able to recognize this as a link. Bear in mind that Google can recognize some JavaScript-coded links, depending on how the link is coded. For information on how to construct a JavaScript-coded link, look anywhere on the Web for samples. The best way is to use a separate JavaScript (.js) file to store the URLs.
