Backlink

Backlinks are links that refer on the website, which is to optimize. Backlinking is an important part of the off-site-optimization, which contains actions taken not on the own website but on others to heighten the popularity of the own site. Search engines like Google, Yahoo or Bing see the amount of backlinks as a indication of the popularity or importance of a web-site. Link building is essential for a successful SEO-strategy.
