Let’s grab a random site like the Children’s Brain Tumor Foundation. I know their website’s canonical version is http://www.cbtf.org/ but I wanted to know if they were splitting their page rank and opening themselves up to duplicate content by not effectively redirecting the non-www version of their site to the www version. It should be simple enough to check that manually, but I know that by doing this query in Google I might find some interesting issues in addition to that.

So, I did a quick Google search with the query: [site:cbtf.org -inurl:www] which removed all indexed versions of the site with www. The results were surprising:
http://www.google.com/search?hl=en&safe=off&q=site%3Acbtf.org+-inurl%3Awww&aq=f&aqi=&aql=&oq=

This seems like a simple check just to see if a site has a 301 redirect setup properly for non-www to www. But when we do this search we capture even more abnormalities like what you see in the search results above. They have a ww. indexed! There isn’t a duplicate version of their site there, which is what we’d typically see with maybe a https or www1 or www2. There is however a duped version of their developer’s site, which should probably get addressed.

We’ve worked on sites where we go through this process and discover literally hundreds of duped versions of a site!

When I’m looking for academic content it’s very useful to use these operators. But from time to time Google is going to add some more and deletes some old. Thats why you have to stay tuned for the latest ones.
Another article just introduced some more operators providing useful videos:

But compared to blekko Google cannot sort the results – damn. I hope this will come to Google, too soon…

One more operator I find useful occasionally is the + sign immediately before a keyword. It makes Google to look for your exact word, without spelling corrections, synonyms, etc. Helps when Google is annoyingly trying to be smarter than you.
