1. Backlink Gap
Best for: Discovering competitor backlinks you can realistically earn
Backlink Gap by SEMRUSH is designed to uncover one of the easiest link building wins: sites that already link to your competitors—but not to you.
By comparing your domain against up to four competing websites, the tool highlights shared backlink sources you’re missing, turning competitor research into a ready-made outreach list. So if you are looking for the best SEO link building tool, you can start with Backlink Gap by SEMRUSH.
How It Works
You enter your site and several competitors, then generate a report showing:
Domains linking to competitors
Which competitors they link to
Which ones don’t link to you yet
From there, you can filter opportunities by relevance and link type, such as listicles, resource pages, or tool roundups.
Why It’s Effective
In a short test, this approach quickly surfaced dozens of high-intent prospects, especially pages already listing similar tools or services.
Because these websites already link to competitors in your niche, they’re far more likely to consider adding you as well.
What I Like About Backlink Gap
High-probability opportunities: These are warm prospects, not cold outreach
Fast discovery: Saves hours of manual competitor analysis
Seamless handoff: Prospects can be sent directly to outreach workflows
While you still need to manually check quality and relevance, Backlink Gap dramatically speeds up the discovery phase.
Pricing
Backlink Gap is available on Semrush plans :
Pro – $139.95/month
Guru – $249.95/month
Business – $499.95/month
A limited free version is available for testing.
How Outreach Empress Uses Backlink Gap
At Outreach Empress, we use Backlink Gap to identify high-probability outreach targets—especially listicles, resource pages, and comparison articles already linking to competitors. These insights are then paired with manual vetting and personalized outreach to ensure links are relevant, contextual, and editorially placed.

Why Use Link Building Tools for SEO?
Before diving into the specifics of each tool, let’s take a look at why link building tools have become essential for modern SEO professionals.
1. Save Time and Scale Your Outreach
Manual link building involves hours of research, writing personalized emails, and following up with prospects. Quality link building tools automate repetitive tasks such as finding contact information, sending email sequences, and tracking responses. What might take days manually can be accomplished in hours with the right software.
2. Discover High-Quality Backlink Opportunities
Top backlink tools use vast databases to identify opportunities you’d never find through manual research. These tools analyze millions of websites, showing you where your competitors are getting links, which sites link to similar content, and which domains have high authority in your niche.
3. Monitor Backlinks and Track Performance
Link building doesn’t end once you secure a backlink. You need to monitor whether links remain active, track your overall link profile growth, and measure how new backlinks impact your rankings. Link building software provides dashboards and reports that give you complete visibility into your link profile’s health.
4. Avoid Toxic or Spammy Links
Not all backlinks benefit your SEO. Some can even harm it. Quality link outreach tools come with spam detection features that help you identify and disavow toxic links before they damage your site’s reputation with search engines.
How to Choose the Best Link Building Tools
With dozens of options available, selecting the right link building software requires evaluating several key criteria:
1. Data Accuracy and Update Frequency
The foundation of any backlink tool is its database. Look for platforms that crawl the web frequently and maintain large, fresh indexes. Tools with outdated data can lead you to dead ends and missed opportunities.
2. Outreach Automation Features
If email outreach is part of your strategy, choose tools with built-in campaign management, email templates, automated follow-ups, and personalization capabilities. This functionality can dramatically increase your response rates while reducing manual work.
3. Backlink Analysis Depth
Advanced SEO tools for backlinks should provide detailed metrics like domain authority, link quality scores, anchor text distribution, and competitor gap analysis. The more insights you have, the better decisions you can make.
4. CRM and Project Workflows
For agencies and teams, project management features matter. Look for tools that allow multiple users to collaborate, organize prospects into campaigns, track relationship stages, and maintain notes on each contact.
5. Reporting and Integration
Your link building tools should integrate seamlessly with other platforms in your SEO stack and provide clear, customizable reports for clients or stakeholders. API access, export options, and white-label reporting add significant value.
