Backlink Gap Analysis
Find Gaps Worth Ranking For Keyword-First Prospect Scoring
You already know competitors have links you don't. What you don't know is which of those linking domains actually matter for the keywords you're trying to rank. Allable maps the gap and ranks every prospect by how much it moves the needle for your specific targets.

You can run a backlink gap report in three different tools and still not know which of those thousands of domains is worth a single outreach email.Semrush and Ahrefs return the raw list, but it is thousands of rows long with no signal about which domains align with what you are actually trying to rank. SE Ranking and linkgap.io surface the gaps, but they live outside your keyword strategy, so cross-referencing is a manual spreadsheet job. The result is a prospecting queue sorted by domain rating alone, where the top domain has nothing to do with the pages you are targeting this quarter.
HOW IT WORKS
From Raw Gap List to Prioritized Outreach Queue
Gap Detection
Allable compares your backlink profile against up to three competitors in one run. Every domain linking to them but not to you appears in the gap list. No manual exports, no cross-tab reconciliation.
Keyword Context
Each gap domain is cross-referenced against your active keyword targets. You see exactly which of your target pages each prospect supports. This turns a generic link list into a ranked outreach brief.
Priority Scoring
Allable scores each gap domain by combining domain authority with keyword relevance to your targets. The highest-value prospects sort to the top automatically. You stop guessing and start with the domains most likely to move your rankings.
Workspace Integration
The gap analysis runs inside the same workspace as your keyword research, content briefs, and rank tracking. Nothing leaves the tab. Your link intelligence is connected to your full SEO strategy from the start.
KEY DIFFERENTIATOR
Link Prospects Ordered by What You Are Ranking For
Allable's backlink gap module runs inside the same workspace as your keyword research and content strategy. Every prospect it surfaces is already mapped to the pages and terms you care about.
- Run a gap scan on up to three competitors — Allable returns every domain linking to them that is not linking to you.
- Each gap domain is matched against your active keyword targets — so you see which prospects support the pages you are actually trying to rank.
- A combined score weighing domain authority and keyword relevance sorts the list — your highest-value outreach candidates surface first, not last.
- Open any prospect directly from the gap view — Allable shows which of your competitors it already links to and what anchor text it used.
- Export the prioritized list to an outreach workflow — or build your outreach brief inside Allable without leaving the workspace.
WHO IT'S FOR
Built for SEO Teams Running Systematic Link Building
In-House SEO Lead
You are responsible for 200+ target keywords and your link profile is thinner than three direct competitors across the board. You run gap reports in Semrush, but the output is a 4,000-row CSV with no filter for the pages that actually need authority. Allable takes that same gap and re-sorts it against your keyword plan, so your next outreach batch goes to the domains that move your priority rankings, not just the highest-DR names on the list.
Agency SEO Manager
You manage backlink strategy across eight clients, each with their own competitor set and keyword targets, and your team runs gap reports manually for every engagement. The process works but takes three tools and two hours per client to produce something actionable. Allable cuts that to a single run per client and outputs a pre-scored prospect list, so your team spends time on outreach rather than data cleanup.
Link Builder
Your outreach hit rate depends on picking prospects who are relevant to the page you are building links for, not just prospects who link to competitors in general. Right now you filter domain lists by hand, checking whether each site's existing content matches your target topic. Allable gives you a pre-filtered list where every prospect is already matched to the target keyword, so your first email goes to someone who has a reason to say yes.

FAQ
Common Questions About Backlink Gap Analysis
- What is a backlink gap analysis?
- A backlink gap analysis compares your backlink profile against one or more competitors to find domains linking to them but not to you. These are sites that have already decided your topic is link-worthy — making them the highest-priority prospects for link building outreach. A gap analysis is faster and more targeted than cold prospect research because it starts from your competitors' validated link sources.
- How does Allable decide which gap domains to prioritize?
- Allable scores each gap domain using two inputs: the domain's authority rating and its relevance to your active keyword targets. A high-DR domain that has no topical connection to your target pages scores lower than a mid-DR domain that already covers your subject area. The combined score is what sorts your prospect list.
- How many competitors can I analyze in one run?
- You can compare your site against up to three competitors in a single backlink gap analysis. You choose the competitors, and Allable returns every domain linking to any of them that is not currently linking to you.
- Is backlink gap analysis included in my Allable plan?
- Yes. There is no separate subscription, no add-on, and no usage cap tied to a higher tier. Backlink gap is available to every Allable user as part of the SEO module.
- How is Allable’s backlink gap different from Semrush or Ahrefs?
- Semrush and Ahrefs have larger raw backlink indexes — if you need the deepest possible data coverage, they remain the benchmark. Allable’s difference is integration: your gap domains are cross-referenced to your keyword targets automatically, so the output is a prioritized prospect list rather than a raw data dump you still need to filter by hand.
- How current is the backlink data?
- Allable’s backlink index is updated on a rolling crawl cycle. For the most time-sensitive link intelligence on very large sites, Semrush or Ahrefs remain the highest-coverage option. For most SEO teams running keyword-targeted link acquisition, the data currency in Allable is sufficient to build an accurate and actionable gap report.
