Google seems to be smarter then i could imagine it is ... for example : If you write a code like this : <a href='site.com/pae.php'></a> (a blind link , without anchor text,images, it's avery hidden link) ... the google bot will follow that link , and it will index it but... it won't pass PR to it, lol
When google crawlling your page, it's not just crawlling your page content, instead it's crawlling the script. So no strange it can follow the link. But how do you know it doesn't pass pr?
This is regex (regular expression) for doings (but it has got no anchor) this not like we visitors who must click the live link.
Interesting....I've found a few "broken" a hrefs in my code from crappy Dreamweaver leaving stuff behind. I hope I'm not being penalized for this stuff.
I RULE THE INTERNET *lightning crash* *thunder* MUHAhahHAHAa. just kidding. The USA rules the internet.
Agree with Mong on this, and just to add, whenever Matt publicly posts about why he banned a site, 9/10 of the time it's because of the silly links above...
