It used to be that Indeed would scour the internet for all job postings. Wheter the site was a pay for a posting site like CareerBuilder, a company website, or a free posting site like Craigslist or Ebay Classifieds - the job posting would appear on the results of the Indeed job search engine result. Not any more. They no longer show results from free posting sites. So if your posting appears on Craigslist, ebay classifieds, or other free sites, it will no longer appear on Indeed.
This means, the recruiting strategy of posting on a free site and then have it appear on Craigslist will not work anymore.
