In answer to your questions:
1. You can load as many job queries as you want, but you do need to specify the keywords. The
SimplyHired setup documentation can give you a better idea of what's involved.
2. There's no number as such, the jobs are dynamically displayed once the customer searches, so it depends on what jobs are available.
3. As jobs from the job aggregator plugins are dynamically displayed it means that they'll appear on your sites search results, but the customer would have to click them to redirect to their site for full information. This means yes, it will show their branding. Thanks.
