Coral Sea Scuba & Water Sports

How a long-term technical SEO and content strategy more than doubled organic search traffic.

Coral Sea Scuba & Water Sports is an established scuba retail, training, equipment-service, rental, and e-commerce business in Grants Pass, Oregon.

The business already had years of industry experience, a large online catalog, training programs, and strong local recognition. The challenge was making sure Google could clearly understand the website, properly crawl and index important pages, and connect customers with the products, classes, and services they were actually searching for.

Client: Coral Sea Scuba & Water Sports

Industry: Scuba Retail, Training, Rentals & Equipment Service

Location: Grants Pass, Oregon

Platform: BigCommerce

The Results

To measure progress, we compared two equal three-month periods: November 1, 2025 – January 31, 2026 and May 1 – July 31, 2026.

+146% Organic Search Sessions
+129% Engaged Organic Sessions
+63% Google Search Clicks
20.3 → 11.3 Average Google Search Position

Organic Search sessions increased from 2,770 to 6,820. That is an increase of approximately 146%.

Engaged organic sessions increased from 1,797 to 4,116, an improvement of approximately 129%.

Google Search Console recorded an increase from approximately 2,760 to 4,510 search clicks during the comparison periods.

Average Google search position improved from approximately 20.3 to 11.3, moving the site’s overall visibility much closer to the first page of Google search results.

The important result was not one keyword moving up. The entire website became more visible across a much broader range of commercial and local searches.

The Challenge

Coral Sea Scuba had a large amount of valuable content and inventory, but the website was not organized in a way that allowed search engines to fully understand the relationship between products, product categories, training programs, equipment services, and local business offerings.

Technical Issues

  • Indexing inconsistencies
  • Crawl inefficiencies
  • Duplicate and legacy URLs
  • Structured-data issues
  • Weak internal connections between related pages

Content & Search Issues

  • Thin category content
  • Under-optimized product pages
  • Weak metadata and headings
  • Limited local search targeting
  • Important classes and services lacking strong search context

The SEO Strategy

The project was handled as an ongoing SEO program rather than a one-time optimization. Each phase built on the work completed before it.

01. Build Reliable Tracking

Before making major SEO decisions, we needed dependable data. Google Analytics 4, Google Tag Manager, and Google Search Console were configured and monitored so search growth could be measured instead of guessed.

02. Improve Technical SEO

Crawl and indexing issues were reviewed and corrected as they appeared. Redirects, structured-data problems, duplicate paths, indexing warnings, and technical inconsistencies were addressed so Google could more efficiently understand the site.

03. Strengthen Site Architecture

Important products, categories, brands, classes, and service pages were connected through stronger internal linking.

Instead of treating every product page as an isolated page, related content was organized into search-friendly clusters.

04. Optimize Category Pages

Product categories were expanded with useful search-focused descriptions, FAQs, internal links, headings, and clearer keyword relevance.

Work included major scuba-equipment categories such as regulators, fins, masks, wetsuits, tanks, dive lights, cameras, gear bags, weights, gloves, booties, hoods, spearguns, snorkeling gear, regulator parts, and more.

05. Improve Product SEO

Priority product pages were rewritten and optimized using stronger titles, headings, descriptions, specifications, FAQs, and internal links.

This helped individual products begin appearing for highly specific searches involving replacement parts, scuba accessories, spearguns, BCDs, tanks, computers, masks, and equipment components.

06. Build Stronger Brand & Topic Hubs

Brand and category relationships were strengthened so Google could better associate Coral Sea Scuba with specific scuba manufacturers, equipment types, and product families.

The regulator-parts and Oceanic content clusters became especially useful examples of this strategy.

07. Improve Local Search Visibility

The website and Google Business Profile were aligned around the business’s real services, including scuba instruction, certification, equipment rental, equipment repair, scuba gear sales, tank air fills, hydro testing, visual inspections, dive travel, and specialty courses.

Photos, services, categories, business information, and local relevance were continuously improved.

08. Monitor Search Data and Refine

Search Console data was used to identify pages and queries already gaining visibility. Those opportunities then guided future optimization work.

This created a feedback loop: optimize, measure, identify new opportunities, and improve again.


Expanding Beyond Branded Searches

One of the strongest indicators of progress was the variety of new search terms generating impressions and clicks.

Coral Sea Scuba was no longer relying primarily on searches for the business name. Google began displaying the site for product-specific, training-related, and commercial searches such as:

  • Harpoon gun
  • Spear gun
  • Atomic TFX
  • Oceanic regulator parts
  • Oceanic FDX10 service kit
  • Mares Puck Pro battery cover
  • Scuba lessons near me
  • Open water diver certification
  • Scuba certification near me
  • Scuba shop near me
  • Dive shop
  • Scuba diving Oregon

That shift is important because non-branded searches introduce the business to customers who may never have heard of Coral Sea Scuba before beginning their search.


Organic Traffic Became a Much Larger Part of the Website

The Google Analytics comparison shows that Organic Search grew from 18.34% of total sessions during the earlier period to 29.12% during the later period.

At the same time, organic visitors continued to show strong engagement. During the May–July period, Organic Search produced a 60.35% engagement rate and averaged approximately 9 events per session.

That matters because increased traffic is only useful if visitors interact with the site. The data shows that the additional organic traffic was not simply empty page views.


Why the Strategy Worked

No single SEO change created the growth.

The results came from consistently improving multiple parts of the website at the same time:

  • Technical crawlability
  • Indexing
  • Site architecture
  • Internal linking
  • Product content
  • Category content
  • Local search relevance
  • Google Business Profile signals
  • Analytics and Search Console monitoring
SEO became an ongoing business system instead of a collection of isolated page edits.

The Work Continues

Coral Sea Scuba remains an active SEO client.

New products, classes, inventory changes, Google indexing issues, structured-data changes, local-search opportunities, and Google Business Profile updates continue to create new optimization opportunities.

That ongoing work is part of what protects the gains already made and creates room for continued growth.
