Backlinks
A backlink is a link from one website to a page on another website, also called an inbound link.
Key takeaways
- Backlinks are links from external sites to yours, used by search engines as trust signals.
- High-quality backlinks from relevant, authoritative sites boost rankings and referral traffic.
- Natural link earning (via great content and outreach) is safer than manipulative tactics.
- Monitor your backlink profile to spot and disavow harmful links.
Search engines use backlinks as signals of trust, relevance, and authority, helping pages earn better visibility in search results.
Example of a Backlink
Imagine a food blog writes a post about healthy breakfast ideas and includes a link to your recipe page. That link from the food blog to your site is a backlink. If the food blog has high authority (e.g., a popular site like Allrecipes), that backlink carries more weight than a link from a low-traffic personal blog.
When Should You Focus on Backlinks?
- You want to improve search rankings – Backlinks are a major ranking factor.
- You need more referral traffic – Links from popular sites can send visitors directly.
- You are building brand authority – Earning links from respected sources builds credibility.
- You have great content – If you have linkable assets (guides, research, tools), backlinks amplify their reach.
What a Backlink Is Not
- Not a guarantee of ranking – Even high-quality backlinks don't guarantee top positions.
- Not the same as a referring domain – One domain can link to you multiple times, but each link is a backlink.
- Not always do-follow – Nofollow links don't pass link equity but can still drive traffic.
- Not a one-time effort – Backlinks need monitoring; some may become broken or toxic.
Quick Start: How to Start Earning Backlinks
- Audit your current backlinks using a tool like Ahrefs or Search Console.
- Create linkable assets – Write in-depth guides, original research, or infographics.
- Reach out to relevant sites – Guest post, offer expert quotes, or suggest broken link replacements.
- Monitor your profile – Check for new links, lost links, and toxic links monthly.
- Disavow harmful links – Use Google's disavow tool if you see spammy or paid links.
Common Backlink Mistakes to Avoid
- Chasing quantity over quality – One link from a high-authority site is worth more than dozens from low-quality directories.
- Using unnatural tactics – Spammy outreach, forced anchor text, footer-wide links, or undisclosed paid links can lead to penalties.
- Ignoring backlink monitoring – Toxic links can harm your rankings; check your profile regularly.
- Treating all backlinks equally – Evaluate each link's relevance, authority, and context.

What is the difference between do-follow and nofollow backlinks?
Do-follow links pass link equity (ranking power). Nofollow links do not, but they can still drive traffic and add diversity to your backlink profile.
