Backlinks remain one of the most important ranking factors for SEO success. However, manually building high-quality backlinks can be an arduous and time-consuming process. This is where backlink APIs come in. By automating the process of link acquisition, they can revolutionize your link building strategy.

Here, we will discuss the significance of backlinks, provide an overview of the 10 top backlink APIs to integrate into your workflow, address common questions around these tools, and give recommendations for effectively leveraging backlink APIs. Let’s get started!

The Crucial Role of Backlinks in SEO



Websites with a substantial number of backlinks tend to achieve higher search engine rankings. According to one ranking factor analysis, backlinks constitute over 20% of Google’s algorithm. They serve as credible votes of confidence in a website’s value when granted by trustworthy external sources.

Given their weight in SEO, a solid backlink profile is essential for visibility and organic traffic. However, manual outreach efforts don’t easily scale. This underscores the need for both backlink profile analysis and API integration to automate link building.

Manually identifying link opportunities can be akin to finding needles in a haystack. Backlink APIs analyze link data to surface actionable prospects and streamline outreach. As Gianluca Fiorelli puts it:

“SEO experiments that once took 6 months can now be completed in 2 weeks thanks to automation”.

While backlink APIs significantly streamline the link-building process, effective backlinks management is key to leveraging these tools to their full potential. 

Let’s explore 10 powerful backlink API tools to step up your link building game:

1. Ahrefs


Ahrefs’ backlink API allows users to analyze the backlink profile of any website or competitor domain. Its backlink index now includes over 12 trillion backlinks from over 194 million root domains.

Users can access historical data on total backlinks, referring domains, linking pages, anchor text usage, and more. Ahrefs also identifies unlinked brand mentions across the web to uncover new link building opportunities. Use these backlinks for your SEO gains by understanding the basics of link building for SEO.

2. SEMrush

The SEMrush backlink API provides rich backlink data to inform strategy. Users can analyze top linking domains, monitor for lost backlinks or gained backlinks, assess anchor text diversity, and reveal links by specific topic. SEMrush also enables automated workflows. Users can set up sequences to automatically discover prospects, customize outreach templates, send follow-ups, and then track link earn rates.

3. Majestic

Understanding the domain authority of linking sites is crucial for assessing the quality of backlinks. Tools like Majestic offer insights into metrics such as Trust Flow and Citation Flow, but for a deeper dive into domain authority, consider exploring additional resources.

Citation Flow indicates the number of unique linking sites to a target domain or URL, while Trust Flow rates the trustworthiness of those sites. Majestic also calculates the percentage of live backlinks versus dead links with its Fresh Index, informing users of stability.

4. Moz

Moz offers highly detailed spam scores through its link API, rating the quality and relevance of individual backlinks on a 0 to 100 scale. Moz also provides a top linked-to-page analysis, revealing specific assets earning the most links to replicate content pillars across domains.

Backlink checker features within APIs like Moz offer deep dives into the health and quality of backlinks. This feature provides metrics which are crucial for evaluating the worthiness of each link and ensuring your backlink profile remains robust and penalty-free.

5. Backlinko

The Backlinko backlink API also specializes, for example, in identifying new backlink opportunities from broken links. Its 404 monitoring tool tracks broken backlinks pointing to 404 pages and then surfaces contact information for outreach. Backlinko also reveals sites linking to competitors but not a target website. Users can reach out to emulate competitors’ successes by getting linked from the same domains.

6. Linkody


Linkody facilitates your link building campaign by tracking online brand mentions for link request opportunities. After connecting Gmail and LinkedIn accounts, Linkody monitors conversations across these channels. Once a website mentions your brand, Linkody prompts you to send an automated or customized link request.

7. Pitchbox


Pitchbox enables users to earn high authority publication backlinks by pitching content ideas to journalists. Users simply join interest-based reporter groups within Pitchbox to access writer preferences and guidelines. By crafting targeted pitches, users achieve high acceptance rates and secure valuable published backlinks.

8. Link Miner

Link Miner taps into expired domains and withdrawn pages cataloged in web archives to uncover old, authoritative domain name links pointing to a site or competitor. After discovering these domains, users can recover the links by reactivating expired domains or requesting re-links from new site domain owners.

9. Link Facet

Link Facet scans public business listings/citations and identifies which resource pages are missing a link back to your website. With a single click, users can file automated link addition requests to listings lacking a link. Once site links are added, users earn local SEO value, visibility boosts, and referral traffic.

10. Globat

Globat allows users to request backlinks from other websites, via their personalized email templates for blogger and webmaster outreach campaigns. After discovering relevant sites through Globat’s search and filters, users customize broadcast email campaigns with link insertion requests. Globat then facilitates sending, tracking opens/clicks, and scheduling automated follow-ups.
