Summary
On-page technologies are a double-edged sword. New technologies — such as Flash and AJAX — may
be boons for usability and have a certain “cool factor,” but may make a site entirely invisible to a search
engine spider if not used properly. Even seemingly superficial things like the structure of a link may
severely impact web site spiderability, and hence search engine friendliness. Lastly, as stated in Chapter 2,
invisible on-page factors are not regarded with any confidence by search engines. So despite the fact that
tags such as
<noembed>
and
<noscript>
were created to address these issues, your success with them
will likely be limited.
