What is link baiting?

Linkbaiting sounds like a bad thing, but especially if it's interesting information or fun, it doesn't have to have negative connotations. I hereby claim that content can be both white-hat and yet still be wonderful "bait" for links (e.g. Danny's spam email analysis). And generating information or ideas that people talk about is a surefire way to generate links. Personally, I'd lean toward producing interesting data or having a creative idea rather than spouting really controversial ideas 100% of the time. If everything you ever say is controversial, it can be entertaining, but it's harder to maintain credibility over the long haul.

Link bait means piece of content within website and especially designed for getting links from different web directories that is called link bait. Example
1)   Great & meaningful content
2)   Images

Link baiting is when you entice people to link to their sites by giving some sort of incentive or making it attractive to do so.
