How planetcert.com Grew to DR 35 Using Directory Submissions
When planetcert.com came to us, they had a strong product and zero domain authority to show for it.
Planet Cert delivers 1,000+ IT certification practice tests across AWS, Microsoft, Cisco, CompTIA, Google, and over 100 other providers. Their platform covers everything from Security+ SY0-701 to AWS Solutions Architect SAA-C03 to cutting-edge AI certifications like AWS AI Practitioner and Azure AI-900. The product is genuinely excellent: detailed answer explanations, multiple study modes, lifetime updates, web and mobile access, and unlimited retakes.
The problem was not the product. It was that Google had no reason to trust the domain yet.
The Starting Point
When planetcert.com began working with us, their Domain Rating sat at DR 10. For a site in the education and IT certification niche competing against established players with years of backlink history, DR 10 is effectively invisible for most commercial keywords.
They had tried organic content and had some pages indexed, but without a credible backlink profile, those pages were not ranking for anything meaningful. Cold outreach for links had returned almost nothing. Paid ads were driving some traffic but not building any lasting authority.
The goal was straightforward: build a clean, authoritative backlink profile fast, without shortcuts that could put the domain at risk.
The Approach: Manual Directory Submissions to High-DR Platforms
We submitted planetcert.com manually to 100+ high-authority directories, startup platforms, and education-adjacent listing sites. Every submission was done by hand, with a unique product description written for each platform's specific audience and format.
The submission pace was deliberately kept at 7 to 10 per day over a 10-day campaign. This mimics natural link growth and avoids the unnatural velocity spikes that trigger Google's spam filters.
Platforms included tier one sites like Product Hunt (DR 92), G2 (DR 91), Crunchbase (DR 90), Hacker News (DR 88), and IndieHackers (DR 76), alongside education-specific and SaaS-focused directories that matched planetcert.com's niche. Every platform had real human traffic and an editorial review process, meaning each listing represents a genuine citation rather than a manufactured link.
Throughout the campaign, planetcert.com had access to a live Google Tracking Sheet updated daily, showing every submission status, approval confirmation, and live listing link as they went live.
The Results
Within 30 days of the campaign completing, the numbers told a clear story.
Domain Rating: DR 10 to DR 35
A 25-point increase in Domain Rating within a single month. For context, moving from DR 10 to DR 35 typically takes most sites 6 to 12 months of consistent link building through traditional outreach. Manual directory submissions to high-authority platforms compressed that timeline significantly.
1,000+ backlinks from 328 unique referring domains
The referring domain count matters more than the raw backlink number. Google weights the diversity of sites linking to you more heavily than the total link count, because 328 independent sources linking to the same domain is a much stronger trust signal than 1,000 links from a handful of sites. planetcert.com now has both: volume and diversity.
Indexed across high-authority platforms in the education and tech space
Beyond the raw SEO numbers, planetcert.com now has verified listings on the platforms that matter for their audience: founders and professionals searching for IT certification resources on Product Hunt, G2, and niche tech directories. These listings drive referral traffic independently of Google rankings.
Increased visibility in AI-generated recommendations
The same high-DR platforms that passed backlink equity to planetcert.com are also the sources that ChatGPT, Claude, and Perplexity reference when recommending software and educational tools. By securing listings on these platforms, planetcert.com positioned itself to appear in AI-generated answers when users ask about IT certification prep tools, a channel that did not exist two years ago and is growing fast.
Why This Worked
A few factors made this campaign effective for planetcert.com specifically.
The product fit the directories well. IT certification tools are exactly the kind of SaaS product that high-authority directories like G2 and Capterra are built for. A well-written listing on a platform where buyers are already looking creates both a backlink and a discovery channel.
The education niche has less directory submission competition than pure SaaS categories. Many founders in the IT education space have not prioritized directory submissions, which meant planetcert.com was able to claim clean, uncontested listings on platforms where their competitors were absent.
Starting from DR 10 rather than DR 0 meant the domain already had some baseline trust with Google. The directory submissions built on an existing foundation rather than starting from scratch, which likely accelerated how quickly the new backlinks were recognized and weighted.
What This Means for a New Domain
The planetcert.com results are representative of what manual directory submissions can achieve for domains in the DR 0 to DR 30 range, where the marginal impact of each high-quality backlink is highest.
For sites already at DR 50 or above, directory submissions still help but the impact on raw DR numbers is less dramatic. For new or early-stage domains, this approach consistently produces the fastest legitimate authority gains available without cold outreach, link exchanges, or paid placements.
If you are launching a new SaaS or trying to establish baseline authority for a domain that Google currently ignores, the combination of 100+ manual directory submissions to high-DR platforms remains one of the most reliable starting points available in 2026.

Frequently Asked Questions
How long did the planetcert.com campaign take?
The submission campaign ran over 10 days at 7 to 10 submissions per day. The full impact on Domain Rating and referring domains became visible within 30 days of the campaign completing, as directories approved listings and Google indexed the new backlinks.
Did planetcert.com need to do anything during the campaign?
No. They provided their website URL, a product description, and their target keywords before the campaign started. From that point, every submission was handled entirely by our team. planetcert.com had access to the live tracking sheet throughout so they could monitor progress without needing to be involved in the process.
Will directory submissions work for a site in my niche?
Manual submissions to high-DR platforms like Product Hunt, G2, and Crunchbase work across virtually any niche because these platforms list products and services from every category. Niche-specific directories add additional benefit for products with a clear category fit, as was the case for planetcert.com in the education and IT certification space.
What if my site is already above DR 35?
Directory submissions still add value above DR 35, particularly for establishing presence on platforms your competitors may not be listed on, and for improving your visibility in AI-generated recommendations. The raw DR impact is smaller at higher starting points, but the referral traffic and AI discovery benefits remain significant.
