Follow these best practices to earn links ethically:

  • Vet sites carefully – Thoroughly assess sites you might request links from or publish guest posts on based on merit factors like authority, trust, relevance, and quality. Avoid manipulation with mass automated links.
  • Produce genuinely helpful content – What unique value can you offer readers? Useful content that actually gets links tends to solve problems, satisfy needs, uncover data, analyze ideas, provide actionable advice etc.
  • Only request relevant links – Links should occur organically because they make sense for the content itself to guide readers. Don’t force links just for SEO value. Relevance is key.
  • Build relationships first – Initiate personal outreach by providing value before asking for anything in return. Comment on sites, share content, offer useful resources etc. to establish rapport.
  • Respond ethically to Google updates – If hit by an algorithm update penalizing unfair SEO tactics, focus on improving legitimate value for people over search bots. Don’t try to reverse engineer ranking shifts.

The safest approach is building links slowly based on merit rather than hacking shortcuts that might crash. Tools should support but not replace sound strategies centered on high-quality content and ethical practices.
