Indeed.com (or its national variants) seems to be the place a lot of these kinds of employer advertise.

TY. Stupid q. Searched my area and found lots of listings. 1 do employers know they are on indeed? And 2 how does indeed get listings? Sorry for the real basic level.

In general indeed gets its listings by aggregating them from across the web. They also have a lot of people post directly on their site. They also have the Job Spotter app that gives rewards to people to find and upload pictures of "Help Wanted" signs.

I don't know the answer to #1.

Regarding #2, indeed appears to be some kind of job site search engine, a la google, as most links I've clicked on there have sent me to some recruitment/agency/etc. website... but sometimes you find direct links.

When my family business was looking for a bookkeeper, we listed on Indeed directly. It was really inexpensive and very effective; we received many qualified applicants.

My company recruits heavily on college campuses via their career departments. We also use Indeed. We've tried out Craig's List, but haven't had much luck.

Craigslist.

I thought Craigslist was only for jobs if you want to be in the... err.. adult services industy

I got my first office job, at a law firm, on Craigslist.

They nuked that portion of the site a while back.
