Our Methodology
Last updated: March 2026
Backlynk maintains a curated database of 200+ web directories across 195 categories. This page explains exactly how we find, verify, and score each directory — and how submissions are processed to ensure maximum SEO value while following white-hat best practices.
1. Directory Discovery
We source directories from multiple channels to build the most comprehensive database in the industry:
- •Aggregator research — We analyze 120+ curated lists, GitHub repositories, and meta-directories that catalog web directories.
- •Competitor backlink analysis — We study where competitors in various niches have successfully built directory backlinks.
- •Community submissions — SEO professionals and directory owners can suggest directories for inclusion in our database.
- •Industry monitoring — We track new directories as they launch in emerging niches like AI tools, SaaS, and developer platforms.
2. Verification Process
Every directory goes through a multi-step verification before being added to our database:
Accessibility Check
We verify the directory is live, loads within 10 seconds, and has a working submission form. Directories behind paywalls or with broken forms are excluded.
Domain Rating Verification
We check each directory's Domain Rating (DR) using Ahrefs data. Only directories with verifiable DR scores are included. DR scores are updated quarterly.
Link Type Detection
We determine whether the directory provides dofollow or nofollow links by analyzing existing listings' HTML source code. This is verified by checking multiple listed sites.
Spam Assessment
We check for signs of low quality: excessive ads, link farms, irrelevant categories, deindexed pages, or Google Safe Browsing warnings. Directories flagged on any criterion are rejected.
Category Classification
Each directory is classified into one of our 195 categories (e.g., AI Tools, SaaS, Finance, Health, Developer, Startup). Niche-specific directories are tagged accordingly to improve matching.
3. Directory Scoring & Tier System
We evaluate thousands of directories but only accept those that pass our quality criteria. The 200+ directories in our curated database are organized into tiers based on their DR score. Higher-DR directories pass more link equity and are available on higher-tier plans:
| Tier | DR Range | Directories | Available On |
|---|---|---|---|
| Standard | DR 0 – 30 | 176+ | All plans |
| Enhanced | DR 31 – 55 | 200+ | Growth+ |
| Premium | DR 56 – 80 | 219+ | Pro+ |
| Elite | DR 81 – 96 | 220+ | Agency |
Directory counts are cumulative — each tier includes all directories from lower tiers. Counts grow as we add new verified directories.
4. How Submissions Work
When you start a submission campaign, here is exactly what happens:
- 1Queue creation — Your site details and selected directories are queued for processing. Higher-tier plans get priority queue placement.
- 2Submission workflow — Our submission engine navigates to the directory, processes the submission form with your site information, and handles verification steps automatically.
- 3Email verification — If the directory sends a confirmation email, we automatically detect and verify it. This step is fully handled without any action needed from you.
- 4Status tracking — Each submission is tracked in real-time through stages: Queued, Submitting, Submitted, Verified, or Failed. You can monitor progress in your dashboard.
- 5Backlink verification — After submission, we periodically check the directory to verify your listing and backlink are live. You receive alerts if a backlink goes down.
5. SEO Safety Measures
We implement multiple safeguards to ensure all submissions are safe and follow white-hat SEO practices:
- ✓Natural pacing — 15-30 second delays between submissions to ensure natural submission patterns. No bulk blasting.
- ✓Reliable delivery — Submissions are processed through resilient infrastructure designed for consistent delivery and monitoring.
- ✓No duplicate submissions — We track every submission to prevent duplicate entries that could appear spammy to search engines.
- ✓Quality-only directories — No link farms, PBNs, or Google-penalized sites in our database. Regular audits remove any directories that decline in quality.
- ✓Varied anchor text — We use natural anchor text variations (brand name, URL, descriptive text) rather than keyword-stuffed anchors.
6. Ongoing Quality Maintenance
Our directory database is not static. We continuously maintain and improve it:
- •Quarterly DR updates — Every directory's Domain Rating is refreshed quarterly to ensure accuracy.
- •Dead directory removal — Directories that go offline, become link farms, or get deindexed are removed from the database.
- •New directory additions — We add 20-50 new verified directories per month as new quality directories launch.
- •Link type re-verification — Dofollow/nofollow status is re-checked quarterly, as directories sometimes change their linking policies.
- •Success rate tracking — We monitor submission success rates per directory and investigate directories with declining acceptance rates.
