I just learned something about Google from eGrabber. It's about the Google 'allinanchor' tab. If you want a really humongous collection of pages relating to jobs then use the following search string:
If you're interested in just the pages in Canada then don't forget to select 'pages from Canada'. Lotsa niche sites as well as the big ones.
Interested in jobs in the Rockies? Try searching for rockies within the results from the query just mentioned.
I can't believe this! No more adding to one's list of job sites by onesies and twosies.
