The Challenge: Expanding Organic Search Visibility in a Competitive Healthcare Market
When Webolutions began working with South Denver Cardiology in July 2015, the organization’s website held just 58 first-page keyword rankings in its historical SEMrush tracking.
South Denver Cardiology wanted to expand its national organic search visibility across cardiovascular health information, diagnostic testing, and related medical services.
Competing for healthcare-related searches presents significant challenges. Search engines must evaluate content dealing with medical topics where accuracy, relevance, and trust are especially important. At the same time, healthcare organizations compete with hospitals, established medical publishers, health information websites, and other providers for prominent organic search positions.
For South Denver Cardiology, the objective was not simply to improve a few individual rankings. It was to expand the website’s overall organic search footprint so that more relevant cardiovascular topics could achieve visibility in Google’s search results.
Webolutions developed a long-term SEO services program to support that objective.
The SEO Strategy: Building Search Visibility Through Continuous Optimization
Webolutions began providing technical and on-page SEO services in July 2015. Rather than treating SEO as a one-time website project, the engagement involved ongoing optimization and performance measurement.
Technical SEO: Supporting Search Engine Accessibility
Technical SEO helps ensure that search engines can discover, crawl, interpret, and index website content.
For a healthcare website competing across numerous cardiovascular topics, maintaining technical accessibility is an important foundation for organic visibility.
Webolutions’ ongoing technical SEO work formed part of the broader effort to support South Denver Cardiology’s expanding presence in organic search.
On-Page SEO: Strengthening Relevance Across Cardiovascular Topics
On-page SEO was another ongoing component of the engagement.
Webolutions worked to strengthen the relevance of website content for cardiovascular health information, diagnostic services, and related patient searches.
Effective on-page optimization helps search engines understand what individual pages address and how those pages relate to the information users seek.
These efforts reflected established SEO fundamentals, including content relevance, search intent, and search engine accessibility.
Backlink Building: Adding an Authority-Development Component
In June 2022, Webolutions expanded the engagement to include dedicated link building services.
This added an external authority-development component to an SEO program that had already produced substantial ranking improvements.
The timing is important: by May 2022, immediately before dedicated backlink building began, South Denver Cardiology had already reached 2,756 first-page keyword rankings.
That milestone provides evidence of substantial search visibility growth during the earlier technical and on-page SEO phases.
Backlink building subsequently became part of the ongoing strategy, complementing the optimization work already underway.
The Results: First-Page Keyword Rankings Increased 6,602%
South Denver Cardiology’s historical SEMrush tracking demonstrates a dramatic expansion in the number of keywords appearing on the first page of organic search results.
In July 2015, the website held 58 first-page keyword rankings.
By May 2022, the number had reached 2,756.
In May 2026, historical tracking recorded 3,887 first-page keyword rankings.
This represents a 6,602% increase in first-page keyword rankings between July 2015 and May 2026.
First-Page Keyword Ranking Milestones
| Reporting Period | First-Page Keyword Rankings |
| July 2015 | 58 |
| May 2022 | 2,756 |
| May 2026 | 3,887 |
Chart 1: South Denver Cardiology First-Page Keyword Ranking Growth, July 2015–May 2026.
The growth represents a substantial expansion in the number of tracked search queries for which South Denver Cardiology appeared among the first ten organic results.
The May 2022 milestone is particularly noteworthy. By that point, the website’s first-page ranking count had grown approximately 47-fold compared with July 2015, before dedicated backlink building was introduced.
The May 2026 result demonstrates that the website’s historical first-page ranking footprint continued to expand over the longer engagement.
These figures describe historical ranking counts rather than improvements in the positions of a fixed set of keywords. Changes in SEMrush keyword coverage and reporting methodology should also be considered when interpreting the long-term comparison.
Top 3 Keyword Rankings Increased 3,500%
First-page rankings demonstrate the breadth of organic search visibility. Rankings in the Top 3 positions provide another perspective on how prominently a website appears for its tracked keywords.
South Denver Cardiology also achieved substantial growth in these highly visible organic positions.
In July 2015, the website held 32 Top 3 keyword rankings.
By February 2026, its historical SEMrush tracking recorded 1,152 Top 3 keyword rankings.
That represents a 3,500% increase in the number of keywords ranking in the Top 3 organic positions.

Chart 2: South Denver Cardiology Top 3 Keyword Ranking Growth, July 2015–February 2026.
The February 2026 milestone illustrates the expansion of South Denver Cardiology’s presence among the highest organic positions for tracked searches.
While the first-page and Top 3 results were recorded in different months, both demonstrate substantial historical growth in organic keyword visibility during Webolutions’ long-term engagement.
Ranking Growth Was Accompanied by Extraordinary Organic Traffic Growth
The expansion of South Denver Cardiology’s keyword visibility was accompanied by substantial increases in organic search traffic.
During the national visibility phase of the SEO program, January organic traffic increased from 5,440 in 2016 to 89,896 in 2023.
That represents 1,553% growth in January organic traffic.
Annual organic search sessions also increased from 69,029 in 2016 to 886,323 in 2022, representing approximately 1,184% growth.
These results provide a complementary perspective on the SEO engagement: the website did not simply achieve more keyword rankings; its historical organic search audience also expanded substantially.
The traffic results are documented in our companion article, South Denver Cardiology Organic Traffic Growth Case Study.
Together, the two case studies demonstrate the relationship between expanding organic search visibility and growing organic website traffic, without attributing every change to a single SEO activity.
Adapting SEO Priorities When Business Needs Changed
By 2024, South Denver Cardiology’s business priorities had evolved.
Certain services, including heart calcium score testing, were experiencing appointment backlogs of approximately six months.
Under those conditions, continuing to maximize national visibility for every previously targeted service was no longer the organization’s highest priority.
South Denver Cardiology asked Webolutions to shift greater attention toward attracting organic search visitors from Colorado.
The SEO program was adjusted accordingly, with selected national keyword opportunities deprioritized in favor of greater geographic relevance.
This change reflects an important principle of effective SEO: the highest ranking count is not always the most meaningful business outcome.
A website can attract substantial national search traffic while a healthcare organization places greater value on reaching prospective patients within its service area.
The revised approach incorporated geographic targeting principles associated with local SEO strategy, while continuing to support the organization’s broader organic search presence.
Notably, South Denver Cardiology recorded its highest historical first-page keyword count in May 2026, after the strategic shift toward Colorado traffic.
The program illustrates how SEO priorities can evolve without abandoning the value of the organic visibility established over time.
More Than 11 Years of Continuous SEO Partnership
Webolutions began providing SEO services for South Denver Cardiology in July 2015 and continues to serve the organization as of October 2026.
That represents more than 11 years of continuous SEO service.
During the engagement, South Denver Cardiology experienced substantial historical growth in first-page keyword rankings, Top 3 keyword rankings, and organic search traffic.
The program also evolved to include backlink building and a greater emphasis on Colorado organic traffic as the organization’s priorities changed.
This long-term relationship demonstrates the importance of combining ongoing optimization with performance measurement and strategic adaptability.
Rather than viewing SEO as a short-term campaign, Webolutions has supported South Denver Cardiology through multiple phases of organic search growth and changing business requirements.
What South Denver Cardiology’s SEO Results Demonstrate
South Denver Cardiology’s historical SEO performance illustrates the value of a sustained, comprehensive approach to organic search visibility.
First, long-term SEO investment can substantially expand a website’s search presence. The number of first-page keyword rankings increased 6,602%, while Top 3 keyword rankings increased 3,500% across their respective historical comparison periods.
Second, technical and on-page SEO can establish a substantial foundation for visibility growth. By May 2022, the website had already reached 2,756 first-page rankings before dedicated backlink building began.
Third, effective SEO must adapt to business objectives. When South Denver Cardiology shifted its priorities toward Colorado organic traffic, Webolutions adjusted the program to reflect the organization’s geographic and operational needs.
These results demonstrate the value of an ongoing organic search visibility strategy supported by consistent measurement, optimization, and strategic refinement.

About These Results
Keyword ranking figures are drawn from South Denver Cardiology’s historical SEMrush tracking reports. First-page rankings refer to tracked keywords in positions 1–10, and Top 3 rankings refer to tracked keywords in positions 1–3.
The comparisons use selected historical reporting dates. SEMrush keyword databases, tracking coverage, and search-result reporting methods have changed over the engagement period. These figures therefore reflect historical tracked ranking counts, not necessarily a constant keyword set measured under identical conditions.
The results represent observed performance during Webolutions’ ongoing SEO engagement. Individual improvements cannot be attributed exclusively to a single optimization activity, and historical results do not guarantee future performance.
