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 problem开发者_开发百科s 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? ThanksI 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.
A banned page has no-cache.
Checking cache is good advice but Banned site might have cache for awhile after the ban.
Cross examine data like
- PR score (if banned PR=0)
- Results for site:domain.com Google search (if banned nothing will appear)
- Check cache (if banned no cache will be available)
If 2 or more provide positive indication of ban, then you've been banned. (unless it`s a new, yet to be, indexed domain)
Also you should sign up in WMT (Web Master Tools) and if you get banned you might receive this notification: http://support.google.com/webmasters/bin/answer.py?hl=en&answer=35665
Hope this helps.
