Step 1: Make a list of the type of jobs you want
Step 2: Make a list of 4 or 5 job search engines you typically check
Step 3: Visit feedkiller.com
Step 4: Using tabbed browsing feature of your favorite web browser open new tabs for each of the search engines. Do a typical search for the type of job you're looking for.
Step 5: Grab the RSS feed address for the search engine results and drop it into feedkiller. This part gets a little tricky, play with the number of results you want to add to your feed (I couldn't get more then 10 at a time). Some job search engines pull in more jobs on a daily basis then others, so be sure to match the number of posts you add with the frequency of new jobs added. This will ensure that you won't see the same jobs each time you check your new feed.
Step 6: After you've added all your job search engines get the code from feedkiller! Paste the code into your webpage.
