Hi All,
if your website links to another site that has been blacklisted by Google this is bad for your ranking
Sites like onlinealley helps you to know if there're problems with a website you are linking to.
Does any Google API Exist .. or how are websites like this checking if a url is banned?
Are they checking the 'PageRank value' or something else?
Thanks

A banned page has no-cache.

thx for your response. what does it mean? I can use no-cache to say the browser to don't cache what I'm serving. How is this related to a website that has been banned?

You check Google if stores cache for that domain, do a query like `cache:stackoverflow.com` this will return output or tell there is no cache. If there is no cache that domain is banned.

can't a developer just instruct google to don't cache a page? this doesn't mean that the website is bad, doesn't it?

I haven't heard of this stuff so far. Anyway if you run `cache:domain.com` it will list all pages cached from that domain. There will be at least one page cached somewhere, nobody blocks the entire content of his domain.

A: 

I like the nofollow suggestion. Its what SO does. Take a look at the page source.

You could also maybe do a 'site:PLACE_URL_HERE' lookup on Google to see if it actually returns any pages.

Also have you looked at the Google Safe Browsing API? Looks like that might be what your after.

I don't even have a website that allows users to enter URL. It was only an example. I can imagine that nofollow can be good. My question is how to check for a banned site - not how to prevent spam o bad links
