Link bait is any content or feature within a website that somehow baits viewers to place links to it from other websites. Matt Cutts defines link bait as anything "interesting enough to catch people's attention.Link bait can be an extremely powerful form of marketing as it is viral in nature.

Link bait in search engine optimization

The quantity and quality of inbound links are two of the many metrics used by a search engine ranking algorithm to rank a website. Link bait creation falls under the task of link building, and aims to increase the quantity of high-quality, relevant links to a website. Part of successful linkbaiting is devising a mini-PR campaign around the release of a link bait article so that bloggers and social media users are made aware and can help promote the piece in tandem. Social media traffic can generate a substantial amount of links to a single web page. Sustainable link bait is rooted in quality content.

Types of link bait
Although there are no clear-cut subdivisions within link bait, many attempt to divide them into types of hooks.There are others, but you see the point. There are two main types of hook in there, the nice hook, and the nasty hook. I'd say in most cases you can get away with a contrarian viewpoint, but not an attack. No one likes an arsehole, so there's no real benefit, as sure you may get a ton of links from outraged blog peers, but they'll likely ignore anything else you write.

Saying that though, it's a judgement call. I've often slammed someone on a blog, but you need to be able to judge it very well. Go just a little too far, and you'll do more harm than good. This is a short list of some of the most common approaches with brief descriptions:

• Informational hooks - Provide information that a reader may find very useful. Some rare tips and tricks or any personal experience through which readers can benefit.
• News hooks - Provide fresh information and obtain citations and links as the news spreads.
• Humor hooks - Tell a funny story or a joke. A bizarre picture of your subject or mocking cartoons can also prove to be link bait.
• Evil hooks - Saying something unpopular or mean may also yield a lot of attention. Writing about something that is not appealing about a product or a popular blogger. Provide strong reasons for it.
• Tool hooks - Create some sort of tool that is useful enough that people link to it.
• Widgets hooks - A badge or tool, that can be placed or embedded on other websites, with a link included.
