5 million to 9.3 million monthly visitors — scaling an already-dominant domain.
When you're already the market leader, link building becomes about defending position and opening new verticals.
LearnStack came to Dot Mirror as an already-established e-learning platform with five million monthly organic visitors and a DR of 74. The challenge wasn't building authority from scratch — it was sustaining and growing organic traffic in a verticals increasingly contested by well-funded competitors (Coursera, Udemy, LinkedIn Learning) who were accelerating their own content and link building programmes. LearnStack needed volume at quality — a consistent pipeline of new referring domains from high-DR sources to maintain their competitive position.
For a domain at DR 74, the priority is quality and topical depth, not volume for its own sake. We focused on two channels: press release distribution to generate consistent media mentions and natural links from news coverage, and targeted link inserts on already-ranking education, business, and technology pages where new referring domains would reinforce specific content clusters. We maintained a minimum DR 50 floor on all placements.
How we built it
Monthly press release distribution
We produced and distributed one major press release per month, timed around LearnStack product launches, course partnerships, and market data. Over 24 months, this generated consistent coverage across Yahoo Finance, MarketWatch, GlobeNewswire, and 400+ regional business publications — 680+ indexed syndications in total, each contributing a referring domain.
Tier-1 link insert programme
We identified education, technology, and professional development articles ranking across multiple Tier-1 domains — sites like TechCrunch, Wired, PCMag, and G2 — and secured 148 link inserts across 24 months. These placements consistently targeted LearnStack's category and course landing pages, reinforcing their authority on competitive commercial terms.
New vertical penetration
LearnStack was underrepresented in the corporate training and B2B learning market. We ran a 6-month targeted campaign placing links specifically on HR, L&D, and enterprise technology publications to open that traffic segment. The vertical now accounts for 18% of LearnStack's total organic traffic.
Publications & placements
86% traffic growth — on a domain already receiving 5 million monthly visitors.
Over 24 months, LearnStack grew from 5 million to 9.3 million monthly organic visitors — an 86% increase that represents 4.3 million additional monthly visits. Their DR moved from 74 to 81. 61 new content cluster pages entered the top three for their target terms. The corporate training vertical — opened through targeted link building — became a meaningful revenue stream that didn't exist at the start of the campaign.
“At our scale, most link building agencies either can't keep up with quality requirements or they plateau quickly. Dot Mirror maintained quality and volume consistently for two years. The results compound in a way that justifies the investment every quarter.”
