I'd like your thoughts on how to identify any "dirty tricks" in reciprocal link exchange.
After checking a few of my reciprocal links today, I have spotted several dirty tricks used by my partners, essentially making my link a one-way to their site.
What do I check for to verify a potential link partner is exchanging links with me ethically?
Here are some examples:
Are there other methods I don't know to check for? Is there an easy way to verify ethical reciprocal links, without having to scrutinize the html or server responses?
Forgive me for reviving a relatively old thread...
The worst dirty trick I've seen recently is people using their root URL with a query string as their links directory, as in http://www.example.com/?cat=widgets&page=1492
The Google Toolbar database apparently canonicalizes all such URLs and displays the root URL's PageRank for these pages, even though their actual PageRank value is... well... who knows? The pages never seem to be cached, and the sites that use this little game seem to always have thousands of pages, so its hardly worth trying to find if these pseudo-link pages are even getting indexed. It just rubs me the wrong way when I see these scams.
Are there other methods I don't know to check for?
Here's another one I just thought of: if other pages of the site link to the links page, make sure these links don't contain a rel="nofollow"! (I suspect that would give the links page a PR 0; that would obviously be a telltale sign...)
