am baffled at how google's spider can not detect a hidden link if a link is inside a div positioned outside the range of an actual page.
Take this site for example:
http://www.lissaexplains.com/index.shtml
if you view the source at the very top you will see html as such:
Code:
<a href=http://www.prescriptionglassesonline.net/>Progressive Glasses</a> LA MODE S2377 S/N:F000322
The glasses is with Semi Rim, stainless Steel frame with comfortable plastic legs, rectangular light & thin Rx lenses, UV & Scratch coatings, and polished edges…A good choice for people daily wearing, very fashionable <a href=http://www.ozglasses.com>Cheap Glasses</a>.

<style>#ads, #ads a{font-size:8px;position:absolute;margin-top:-50px;}</style>
<div id="ads"><a href="http://www.cool-juice.com">free alltel ringtones</a><a href="http://www.freealtonia.com">free verizon ringtones</a><a href="http://www.the-movie-library.com">free movies</a><a href="http://www.musfiesta.com">free mp3</a></div>
<script>document.getElementById('ads').style.top='-50px';</script>
The style is being set for #ads to an absolute position outside the website boundaries, and then applied to the div containing those links. This website also has this same technique applied throughout the page.I am shocked that google does not automatically look for this, or maybe it has detected it and has decided to allow it.
