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.
