About the Client: Caltron Clays & Chemicals Pvt. Ltd.
Caltron Clays & Chemicals Pvt. Ltd. is India’s No.1 manufacturer and supplier of high-quality pharmaceutical and cosmetic raw materials. With an unwavering commitment to quality and innovation, the company stands tall as an ISO 9001 Certified and CRISIL-rated organization.
Unlike conventional players in the industry, Caltron Clays has successfully positioned itself as a modern, future-ready brand catering to global markets. The company specializes in the processing and export of minerals, oxides, and chemicals to clients in India, the USA, UK, South Korea, and South Africa.
Despite its robust supply chain, industry reputation, and product innovation, Caltron Clays faced one major gap—it lacked the digital presence to match its physical dominance.
The Challenge: A Digital Gap Identified by DGMark Agency
Even though Caltron Clays had earned a strong reputation in the pharmaceutical and cosmetics raw material market, their online presence was lagging behind.
One of the biggest challenges was low organic search visibility. Their high-value product pages were nowhere near the top of Google’s search results, causing them to miss out on potential leads.
Additionally, the website had unoptimized content that failed to capture search intent. The messaging wasn’t SEO-friendly, and their product descriptions lacked depth and structure.
Caltron also suffered from limited global reach despite having an international client base. Their digital assets didn’t reflect their worldwide presence. The backlink profile was weak, with very few high-authority domains linking to their content.
Compounding the problem was an outdated website design. It was slow to load, not mobile-friendly, and lacked clear calls-to-action (CTAs). User engagement and conversion rates were abysmally low.
Keyword Domination: DGMark Agency’s Data-Driven SEO Strategy
Recognizing the need for a complete digital overhaul, DGMark Agency launched a comprehensive SEO strategy tailored to Caltron’s goals.
1. In-Depth Keyword Research by DGMark Agency
The first step was understanding the search landscape. Our SEO specialists conducted extensive keyword research, identifying the most searched and conversion-friendly keywords in the minerals and pharmaceutical raw materials domain.
We discovered massive opportunities in search terms like:
- Algae Calcium Powder
- MCHC Powder Ossein
- Active Absorbable Calcium (AAA Cal)
- Marine Magnesium
- Phoscal Fish Bone Calcium
- Algae Calcium Powder in India
- Phoscal Fish Bone Calcium in India
We also ran a competitive gap analysis to uncover areas where Caltron’s competitors were outranking them—and planned how to close that gap.
2. Technical SEO Enhancements Led by Our Digital Marketing Experts
The next step was fixing the on-page elements and improving the technical foundation of the website. We revamped meta titles, descriptions, headers, image alt-text, and internal linking.
We also:
- Enhanced mobile responsiveness
- Reduced page load times
- Created a search-engine-friendly URL structure
- Added structured data and schema for better indexing
These optimizations made the website easier for Google to crawl and index, improving overall site health and authority.
3. Strategic Content Marketing by DGMark’s Content Team
A key pillar of DGMark’s strategy was content. We reimagined the website content to be more informative, keyword-rich, and aligned with buyer intent.
We created:
- Engaging product descriptions highlighting benefits and applications
- Educational blog articles to position Caltron as a thought leader
- Industry guides and whitepapers to support content-driven SEO
This content helped attract a wider audience and encouraged visitors to stay longer, reducing bounce rates and boosting credibility.
4. Off-Page SEO: Authority Building by DGMark Agency
Off-page SEO was another major focus. We improved Caltron’s backlink profile by initiating outreach to high-authority sites in the chemical and pharmaceutical industries.
Tactics included:
- Publishing guest blogs
- Submitting to pharma directories and trade portals
- Collaborating with industry influencers
- Securing coverage through press releases and PR submissions
This approach significantly increased domain authority and gave Caltron’s website the trust signals needed to climb the SERPs.

The redesigned website didn’t just look better—it performed better in every measurable aspect, from speed and usability to conversion rate.
Social Media Management: Brand Building by DGMark Agency
While SEO was driving traffic, we used social media to humanize the brand and expand its presence.
Our strategy included:
- Launching and optimizing official pages on LinkedIn, Facebook, and Instagram
- Designing visually consistent creatives aligned with brand identity
- Publishing regular content such as product spotlights, testimonials, and behind-the-scenes posts
- Running engagement campaigns and B2B ad targeting to connect with key decision-makers
This holistic approach not only boosted awareness but also generated social proof that reinforced trust with potential clients.
