When I do a search for rollbar for the entirety of the Stack Exchange network, I get results for both ordinary content, and advertised jobs, and they look fairly similar. For example, the ad says that it's "Stack Overflow", and nothing in the URL indicates that it's advertising. The only difference is in the icon/thumbnail.
They should either be separate, or there should be more to indicate that a result is an ad, rather than ordinary content.
The Stack Overflow user generated post is How prevent rollbar from reporting errors in the development environment? , while the Stack Overflow ad is https://stackoverflow.com/jobs/130330/entry-level-software-engineer-at-rollbar-rollbar
Clarification: I'm not complaining about the advertising provided by Google - that's clearly marked as advertising, and is easily ignored. I'm complaining about the "result" titled "Entry-Level Software Engineer at Rollbar at Rollbar - Stack Overflow".
