Now that we’ve covered the key aspects of filters and their impact on websites, it’s time to dive into a practical example. Next, we’ll take a closer look at how the Google Medic Update affected the traffic of a medical website and examine effective steps for recovery.

Google Medic Update: How to recover traffic using a medical website as an example

Project Description: A dental clinic website specializing in dental implants faced a significant drop in search rankings after a major Google algorithm update. This caused a noticeable decline in the site’s visibility and, consequently, a reduction in organic traffic for key commercial queries.

Project Goals:

– Restore the website’s visibility for key commercial queries related to dental implants.

– Achieve top rankings in the regional search results to strengthen the clinic’s competitive position and increase the client flow.

Decline in Organic Traffic in August 2021

In early August 2021, the dental clinic’s website experienced a noticeable drop in key organic traffic metrics. Prior to this, the site had shown consistent growth in organic search performance. A large portion of commercial queries, such as “dental implants in [region],” “cost of dental implants,” and “best dental clinics in the region,” ranked in the top positions of search results. However, the sharp decline in rankings for several of these queries raised concerns and required immediate action.

Recovery of Rankings

Before the period of visibility decline, the project performed exceptionally well in organic search, with many key queries confidently occupying top positions. However, in September 2021, a significant drop in rankings was recorded, negatively impacting the site’s visibility and organic traffic volume.

The decline coincided with Google algorithm updates aimed at improving search quality and addressing low-quality pages. As a result, several queries that had previously driven stable traffic lost their rankings. This situation required immediate analysis and the development of a recovery strategy.

Initial Actions After the Visibility Decline

Following the decline in visibility, a detailed analysis was conducted to identify the causes and develop a recovery strategy. The investigation revealed significant changes in the nature of search results for key commercial and informational queries.

Changes in Search Results for Key Queries

For broad semantic queries, informational pages, such as articles and videos, began ranking in the top positions instead of commercial service pages. For example:

– Query: “dental implants”. Informational articles explaining the procedure, benefits, and stages began to dominate the top results, replacing commercial pages of clinics offering the service.

– Query: “wisdom tooth extraction”. Content explaining the process and preparation for wisdom tooth removal started ranking higher than commercial pages with pricing and service descriptions.

Characteristics of the Previous Optimization Strategy

Prior to the visibility decline, the primary focus was on commercial semantics, but pages also included blocks of informational content to attract users with different intents. This approach ensured stable rankings until Google revised its algorithm priorities.

The analysis revealed that pages optimized for both informational and commercial queries began ranking lower than specialized landing pages targeting a single query group.

Analysis results

The study concluded that the decline in the site’s visibility was linked to changes introduced in the Google Medic Update algorithm. The update placed greater emphasis on aligning pages with user intent as well as the quality, expertise, and trustworthiness of the content.

Development of a New Strategy

Based on the collected data, a new strategy was developed, which include:

1. Creating Separate Landing Pages for Informational and Commercial Queries:

  • For queries like “dental implants,” articles were added describing the benefits, process, and types of implants.
  • For commercial queries, dedicated pages were created focusing on services, pricing, and reviews.

Example of a detailed service structure for the “Dental Implants” category by RegisTeam:

2. Improving Content Quality:

  • Incorporating detailed explanations of procedures, references to research, and multimedia materials (photos, videos, infographics).
  • Engaging dentists to write expert articles.

Example of expanded sections for each implant system implementation:

3. Optimizing Pages for Google’s Updated Requirements:

  • Addressing user intent.
  • Enhancing page structure and technical parameters.

The decline in the visibility of the dental clinic’s website was a result of changes in Google’s algorithms, which reprioritized content ranking factors. This issue required a revision of the optimization approach and adaptation to the new search engine requirements. Implementing the new strategy became the foundation for restoring rankings and achieving further growth in search results.

Content Optimization for a Medical Website

To improve the visibility of the medical website and increase its rankings in search results, comprehensive work was done on its content. New sections were added to key pages, and existing sections, such as “Doctors,” “Reviews,” “Prices,” “Licenses and Certificates,” and “Doctor Profiles,” were optimized. Based on the analysis of successful competitor pages ranking in the top results, a list of important sections necessary for a medical website was compiled.

Recommended Pages for a Medical Website

To ensure user convenience and compliance with search engine requirements, the following key types of pages were identified as essential:

  • Contact Page. Includes the address, phone number, directions map, and a contact form.
  • Patient Reviews. A section with genuine patient testimonials.
  • Doctors List. A comprehensive list of all specialists in the clinic.
  • Individual Doctor Pages. Detailed profiles for each doctor, including photos, biographies, experience, and specializations.
  • Licenses and Certificates. A section verifying the clinic’s legitimacy and professionalism.
  • Service Prices. A table with pricing for all services provided by the clinic.
  • About Clinic. A page describing the mission, history, and advantages of the medical institution.
  • Service Pages. Detailed information about procedures offered by the clinic.
  • Disease Pages. Descriptions of diseases, their symptoms, and treatment methods.

Content Structure for Informational and Commercial Pages

1. Informational Pages (about diseases):

  • Definition of the disease.
  • Causes, symptoms, and risk groups.
  • Types of the disease.
  • Prevention and treatment recommendations.

2. Commercial Pages (about medical services):

  • Anchor list for easy navigation on the page.
  • Content blocks describing: Indications and contraindications; Preparation for the procedure; Service process stages.
  • Table with service costs.
  • Patient reviews.
  • Block featuring leading specialists providing the service.

Navigation and Content Optimization

1. Updating the Content of Commercial Pages:

  • Removed excessive informational blocks that did not align with the pages’ commercial purpose.
  • Added new sections with detailed descriptions of the service process, preparation, indications, and contraindications.
  • These changes increased the value of the pages for users, making them more relevant to commercial intent.

2. Creating New Informational Pages:

  • Each page describes a specific disease and is added as a subpage to the relevant service page.
  • In the main menu, these pages are labeled as “Articles”.

Example of informational content block development:

3. Improving Internal Linking:

  • New pages were interlinked and added to the main menu. This improved site connectivity and helped search engines index pages more effectively.

Updating the structure and content of the pages significantly improved their quality and added value. The separation of informational and commercial content strengthened page relevance, positively impacting visibility. Optimized pages became more user-friendly, and enhanced navigation increased engagement and trust in the website.

Link-Building Strategy for a Medical Website

An effective link-building strategy is a crucial stage of promotion, especially for a medical website where trust and authority are key factors. One of the final stages of the project involved a detailed analysis and improvement of the backlink profile to strengthen the site’s rankings. Key changes in the link-building approach:

1. Increasing Mentions on Regional Resources. Published information about the clinic on local websites and portals to attract a target audience from the region.

2. Mentions on Review Platforms. Added information about the clinic on platforms where users leave reviews about doctors, companies, and services. This boosted trust and attracted additional visitors.

3. Publications on Thematic Resources. Focused on publishing articles and mentions on medical and related platforms. Such links not only strengthened the backlink profile but also increased the site’s authority in the eyes of search engines.

Results

After implementing the new link-building strategy, the improvements were noticeable:

  • Increased site visibility in search results.
  • Boosted organic traffic, especially from regional segments.
  • Enhanced trust indicators for the site due to high-quality links from authoritative resources.

Key Focus Areas for a Medical Website Link-Building Strategy:

– Regional platforms that ensure high relevance and local coverage.

– Thematic medical resources that help solidify the site’s expert status. A comprehensive approach to building a quality backlink profile allows for sustainable ranking growth and strengthens the project’s competitive advantages.

Achieved Results

Thanks to the detailed development of additional content blocks, optimization of key sections, and implementation of an effective link-building strategy, the website significantly increased its visibility in search results:

Additionally, traffic dynamics showed steady positive growth, indicating the effectiveness of the measures taken:

Summary

To successfully promote a medical website, it is essential to provide the most complete and detailed information about services. Pages should include not only procedure descriptions but also commercial information, such as pricing, service stages, indications, and contraindications.

Timely identification of visibility declines and the development of a new promotion strategy allow not only for the elimination of root causes but also for ensuring stable growth in the site’s rankings. This approach includes:

Thanks to comprehensive optimization and adaptation to the Google Medic Update requirements, the site not only regained its rankings but also attracts more targeted traffic than before the algorithm changes. This result highlights the importance of regular analysis, content development, and continuous site improvement.
