Why steal job ads?
I don't understand why other websites copy and paste jobs from Ajarn.com, Well I do - it's for content and attracting traffic + revenue. However, copy and paste from an SEO point of view is like pissing in the wind!
There are now duplicate jobs posted and Google hates duplicate content! This means that the site that posted the jobs first (Ajarn.com) is in the highest pecking order in the search engines rankings. The other sites will merely be penalized for duplicate content.
Unless of course the job ads are reworded or spun which would have to be done manually, and is a major pain in the butt + time consuming. You could of course auto spin the content - but then you risk it appearing as unintelligible and unreadable nonsense.
Bottom line - copy and paste will not rank your site!
