  • Content – Great content is key, but needs authority to really excel. If you’d like to know more about content optimization I would suggest checking out the content tools available in this section.

Make sure to follow Google’s quality guidelines:

Domain age vs Website age

This tool calculates Website age because it’s a better and more relevant SEO factor to measure compared to domain age. Especially when you compare Domain and Page Authority, website age shows you how a domain has developed over time. A Website age of 6.4 years means a website is 6 years and 4 months old.

  • Domain age – the number of years since a domain has been registered.
  • Website age – the first time since a website appeared on-line
