Backlink
A backlink is an external link from another website that leads to your page. Backlinks are one of the key factors in SEO promotion: they increase a site’s authority, improve its position in search engine results, and help search engine bots better understand its topic.
What is a Backlink?
A backlink is a hyperlink placed on an external resource that points to your website.
Example:
<a href=”https://site.ru”>Useful Article</a>
If this link is placed on another site, it is considered a backlink.
Why Backlinks are Important
- Improves SEO: Search engines view backlinks as “votes of confidence.” The more high-quality links from authoritative sites, the better the chances of ranking higher in search results.
- Increases Domain Authority: Backlinks influence metrics like DR (Domain Rating), DA (Domain Authority), and PageRank.
- Drives Referral Traffic: Users can click on the links and visit your site directly.
- Builds Reputation: Links from relevant, thematic platforms enhance brand trust.
What Makes a Backlink High-Quality?
A backlink is beneficial if it:
- Comes from a thematic site related to your industry.
- Is placed manually, not automatically.
- Is natural and contextually relevant within the article.
- Is placed on a site with good metrics (traffic, DR/DA).
- Points to a relevant page on your site.
- Has a proper anchor text (natural and meaningful).
Types of Backlinks
- DoFollow: Passes link equity (“link juice”) and directly impacts SEO.
- NoFollow: Does not pass link equity directly but helps diversify the backlink profile and can bring referral traffic.
- Natural/Earned: Appear organically when other sites link to you.
- Paired/Partnership: Placed through link exchanges, outreach, or agreements.
- Crowd Links: Posted in forums, Q&A services, and reviews.
How to Acquire Backlinks
- Outreach: Sending personalized proposals to website owners.
- Guest Posts: Publishing valuable content on other sites with a link.
- Earned Mentions: Receiving links naturally through high-quality content.
- Link Exchanges: Paid placements on link marketplaces.
- PR Publications: Articles in media outlets.
- Crowd Marketing: Participating in discussions on forums and platforms.
- Directories and Rankings: Inclusion in official, thematic lists.
Bad and Harmful Backlinks
- Links from spammy websites.
- Links from irrelevant domains.
- Links from low-quality private blog networks (PBNs) or satellite sites.
- Mass purchases without anchor text diversity.
- Automatically generated links.
Such links can lead to search engine penalties (e.g., Google Penguin).
Conclusion
A backlink is an external link pointing to your site that affects its reputation, authority, and search engine rankings. High-quality backlinks are the foundation of successful SEO, and a well-planned link-building strategy helps a site grow steadily.
