Nowadays more and more webmasters are barring search engines from seeing or following external links. Techniques used include:
- using a rel=”nofollow” on external links,
- barring pages with external links in robots.txt, and
- using 302 (temporary) redirects.
This problem is NOT only limited to traditional pages but also covers any other sites you may think of. Be it blogs, forums etc. I guess this pronounces the death of comment spammers
