In an insightful interview at the Chiang Mai SEO Conference, Kalin Karakehayov, co-founder of SEO.domains, shares his journey and expertise on building profitable online businesses using aged domains.

From his early days in SEO to growing his company into a team of 50, Kalin dives deep into domain strategies, the importance of metrics, and how to effectively use PBNs for SEO growth.

šŸš€ Kalin’s SEO Journey and Company Growth

Kalin started his SEO career 12 years ago, initially focusing on client SEO and growing websites.

He built one site to 15,000 unique visitors per day, but after encountering penalties with Private Blog Networks (PBNs), his team shifted focus to acquiring expired domains.

SEO.domains evolved from an SEO agency to a domain-focused company, now employing 50 people.

Finding the Right Domains

SEO.domains specializes in aged, expired, and country-specific domains. Kalin explains that country domains are often undervalued compared to .com domains and can offer great prices.

He emphasizes the importance of niche relevance when selecting domains to ensure they align with your business goals.

Understanding Domain Metrics

Kalin breaks down the top three domain metrics providers—Moz, Majestic, and Ahrefs.

The Effectiveness of 301 Redirections

Kalin confirms that 301 redirections remain effective for improving Google rankings, particularly when done strategically.

Rather than simply redirecting to the homepage, he advises redirecting to relevant content or HTML sitemaps, making the process smarter and more efficient.

Stronger websites benefit more from these redirects, and for new domains, the risk is minimal.

Boosting Traffic with PBNs

Kalin sees PBNs (Private Blog Networks) as one of the best SEO strategies due to their low renewal costs and long-term value.

If not penalized, a PBN can generate ongoing traffic and link value, making it “cash positive.” PBNs also allow for flexibility in linking to multiple pages in the same niche, providing more opportunities for SEO growth.

Building PBNs: What to Watch Out For

While PBNs can be highly effective, Kalin stresses the importance of diversifying your link-building strategy.

He advises using PBNs alongside other techniques to avoid over-reliance on any one method. PBNs work best in non-U.S. territories, where Google’s scrutiny may be lower.

Additionally, having control over the property allows you to remove links if a penalty occurs.

Kalin’s Experience at the Chiang Mai SEO Conference

Reflecting on his time at the Chiang Mai SEO Conference, Kalin shares that the event had a positive vibe and was an excellent opportunity to meet like-minded SEO marketers.

He appreciates the open, sharing nature of the community and describes the conference as an amazing experience.

Kalin, based in Bulgaria, looks forward to attending more SEO events, including those in the U.S. and Brighton SEO in the UK.
