Mini Case Study: Establishing Digital Authority in Air Quality

A strong online presence is no longer optional. It’s a foundation for success.
It applies equally to specialized engineering fields and the broader business landscape.

That’s why Marquis Intelligence has combined technical expertise with online authenticity to build its digital authority in air quality across the region.

“For Marquis Intelligence to remain successful and sustainable in the fields of ventilation and air quality, our digital framework must be equally strong,” says Vladimir Janaćković, CEO.

This mini-case study presents data from Google Analytics (GA) and Google Search Console (GSC), providing clear evidence of teamwork and consistency behind the significant progress of this small company.

The results reveal a powerful rise in visibility and engagement.
Behind every number are articles written with care, passion, and a genuine wish to provide accurate and helpful information.
It was demanding, but it paid off. Take a look at the numbers that follow.

How Marquis Intelligence Became a Digital Authority in Air Quality

It all began on the company’s 30th anniversary, when, under the guidance of Dragan Varagić, Marquis Intelligence stepped boldly into the digital world.
It was a journey into the unknown. A vast new space that continually expands and offers new opportunities every day.

A well-crafted strategy, combined with dedicated work and technical expertise, enabled the company to gain visibility quickly. First regionally, then internationally.

It started with a single landing page in Serbian. Soon after, an English version followed. The next milestone was launching a bilingual blog, developed simultaneously in both languages.

What Preceded the Visit from Google Bots

Before any significant shift in metrics, a thorough SEO optimisation process was conducted – first on the Serbian version of the site, with the English version still undergoing refinement.

In September 2025, six new bilingual blog posts were published. This move significantly increased the frequency and diversity of content, contributing to stronger signals of relevance and authority.

These strategic activities likely triggered what appears to be a Google reevaluation, a process that often precedes improved search visibility.

A Likely Google Re-evaluation?

On October 10, 2025, Marquis Intelligence’s website experienced a noticeable spike in activity.

According to Google Analytics, the site recorded over 1,500 visits in a single day, including 23 concurrent sessions from Santa Clara and Clifton, both recognised hubs of Google infrastructure.

This type of behavior strongly suggests a thorough technical inspection, most likely a Google content reevaluation. While this cannot be confirmed with absolute certainty, all available indicators suggest that conclusion.

Performance Growth

During the past three weeks, Marquis Intelligence recorded remarkable progress across key website metrics.

• Search clicks: +200% increase.
• Average Google Search position: now consistently on the first page.
• Click-Through Rate (CTR): +78% rise, nearly twice as many users clicked on search results compared to the previous period.
• Mobile “good URLs”: from 0 to 49.
• Active users: +40.9% year-over-year.
• Impressions: +39.5% year-over-year.

As a result, the Marquis Intelligence website now appears regularly on the first page of Google Search results. Several articles are ranked in the top one to two positions for keywords related to ventilation and air quality.

This growth confirms the website’s transition into the “Established Presence” category, a milestone achieved by fewer than 3% of websites at this stage.

Within the context of Serbia’s digital market and the technical B2B niche, such progress is sporadic, yet it stands as clear evidence of authenticity, consistency, and high-quality content.

Global Reach and Engagement

Analytics from October 10 confirm visits from four continents.
Europe. Australia. North America. South America. All within 24 hours.

User engagement time further supports the high quality and relevance of the content:

• Serbia: average of 10+ minutes per session.
• Brazil: over 5 minutes.
• Europe and North America (Germany, UK, Austria, Denmark, Belgium…): several minutes of active engagement.

Such metrics are rare in technical niches and represent a strong confirmation that Marquis Intelligence is successfully emerging as a digital authority in air quality.

“We weave niche stories about air into compelling, data-driven content. Always from a fresh perspective. That’s the difference between the average and the exceptional,” notes Vladimir Janaćković, CEO.

Turning Reevaluation into Recognition

Over 100% growth in indexed pages within 20 days (domain reevaluation and entry into the Increased Crawl Rate phase).

What initially appeared to be a technical anomaly turned out to be a milestone of progress and algorithmic trust.

Google has acknowledged the authenticity, consistency, and structural integrity of the content. Marquis Intelligence successfully transformed this presumed reevaluation into a breakthrough moment, further solidifying its role as a digital authority in air quality.

This process once again confirms that digital excellence is inextricably linked to technical proficiency. They enhance one another.
