Cybersecurity SEO Case Study: How We Drove a 64% Organic Traffic Increase in 5 Months

‍Cybersecurity Case Study Overview

In this case study, you’ll see Castra’s starting metrics, the four-phase strategy we built to address them, and a month-by-month breakdown of how results developed over the five-month engagement. Here’s exactly how each piece came together.

Case Study Key Results at a Glance

Amplifyed focused on three areas that had the highest impact on organic performance: building dedicated service pages for high-intent cybersecurity terms, fixing technical SEO issues that limited crawlability, and creating content around buyer questions across the funnel. Together, these changes helped Castra expand its keyword footprint, improve page-one rankings, and generate more qualified inbound interest.

In October 2022, Castra (now Lumifi), a cybersecurity brand specializing in managed detection and response cybersecurity services, approached Amplifyed for help with their organic growth.

Industry: Cybersecurity (B2B SaaS)

Client: Castra (now Lumifi)

Services Provided: SEO Strategy, Content Strategy, Technical SEO, On-Page Optimization

Engagement Timeline: October 2022 – February 2023 (5 months)

Primary Goals: Increase organic traffic, grow keyword rankings, and generate more qualified inbound leads

When Castra first engaged with us, the situation was stark. The site was barely visible in organic search, lead flow from the website was minimal, and the competitive cybersecurity SERP landscape made every ranking improvement an uphill battle.

Here’s what we were working with:

• Minimal organic traffic: The site averaged just 340 organic users per month.
• Almost no page-one visibility: Only 10 keywords ranked on the first page of Google.
• Limited keyword footprint: Just 350 total keywords were indexed.
• No dedicated service pages: The site lacked pages targeting core offerings like MDR, MXDR, and threat intelligence services.
• Content gaps: There was no blog content addressing buyer pain points or establishing topical authority.
• Technical SEO issues: Broken links, faulty redirects, slow page speeds, and unoptimized metadata were holding the site back.
• Low lead generation: Potential clients' inbound leads from the site were insufficient to sustain business growth.

Achieving Castra’s goals of increasing high-quality traffic and inbound leads would require a comprehensive, phased approach across content, technical SEO, and on-page optimization.

‍

We developed a four-phase cybersecurity SEO strategy designed to build a strong organic foundation and then scale results over the engagement period.

Keyword Strategy & Content Mapping

Our first step was conducting thorough keyword research to identify untapped opportunities and build a content marketing strategy aligned with Castra’s business objectives.

Using industry-leading tools and competitor analysis within the cybersecurity niche, we identified three tiers of keywords:

• Bottom-of-Funnel (BoFU) Keywords: High buyer-intent terms like “MDR services,” “managed SIEM services,” and “threat intelligence services.” We also targeted product-related terms like “Exabeam” and “Palo Alto Cortex” to attract businesses actively searching for cybersecurity solutions.
• Top-of-Funnel (ToFU) Keywords: Informational search terms such as “How to implement proactive cybersecurity in banking” and “What is EDR and XDR?” These would build topical authority and introduce potential leads to Castra’s solutions without direct sales pressure.
• Middle-of-Funnel (MoFU) Keywords: Mixed-intent terms like “EDR vs XDR: Which is best for your business?” and “Best threat intelligence tools.” We planned comparison content to address specific pain points and pre-sell Castra’s services.

We also audited Castra’s existing content to find gaps in keyword coverage, specifically looking for missing search terms with high buyer intent. Additionally, we monitored trending cybersecurity topics like “OpenSSL vulnerabilities” to target timely, relevant search queries.

Content Strategy & Publishing Timeline

With our keywords mapped, we built a phased content calendar that prioritized quick wins first:

• BoFU content (November 2022): Service pages were created first, targeting high-intent keywords like “MDR” and “MXDR.” Each page highlighted the unique value of Castra’s solutions to differentiate from competitors and attract near-conversion leads.
• ToFU content (October – February 2022–2023): Blog posts addressed foundational and trend-based topics, including pieces like “OpenSSL 3.0.7 Released: Everything you need to know” and “People first, automation second: Unlock the real value of your SOC.”
• MoFU content (December 2022 – February 2023): Comparison articles such as “SIEM vs IDS for Enterprise Security” gave users actionable insights and subtly positioned Castra’s services as solutions. We also created content targeting the banking and finance verticals, where cybersecurity demand is high and prospects tend to be higher-value leads.

This phased publishing approach helped Castra target immediate ranking opportunities while building a broader content foundation around buyer questions, service intent, and industry-specific cybersecurity needs.

On-Page Optimization

Beyond creating new content, we optimized Castra’s existing pages to improve their relevance and performance:

• Optimized meta titles, meta descriptions, and headers with target keywords
• Incorporated keywords naturally within body content to improve on-page search engine optimization signals
• Added compelling, solution-oriented CTAs designed to drive leads toward conversion
• Established a logical internal linking structure within topic clusters to improve navigation for both users and search engine crawlers

These updates gave each page clearer search signals, stronger conversion paths, and a more logical structure for both users and search engine crawlers.

Technical SEO Improvements

We conducted an in-depth SEO audit (including Core Web Vitals) to identify and resolve technical issues preventing Google from effectively crawling and indexing the site:

• Fixed all broken links and faulty redirects
• Optimized site metadata for relevance and consistency
• Minified CSS, JavaScript, and HTML code
• Compressed large files and optimized image formats (e.g., JPEG for photos)
• Implemented browser caching for faster repeat-visit load times

As part of our SEO efforts, these technical improvements enhanced site speed, reduced bounce rates, and ensured all pages were discoverable in SERPs.

Our engagement followed a phased rollout over five months:

‍

Each strategic SEO phase built on the previous one. By front-loading high-intent service pages, we created immediate ranking opportunities while longer-term authority-building content matured in the background.

Before the engagement, Castra had limited organic visibility, a small keyword footprint, and few dedicated pages for high-intent cybersecurity services. The snapshot below shows how the site changed after Amplifyed addressed the content, technical, and on-page SEO gaps holding back performance.

This snapshot shows the broader impact of the five-month strategy before looking at the results in more detail. With stronger service pages, improved technical foundations, and clearer keyword targeting in place, Castra was better positioned to compete for high-value cybersecurity searches.

Within five months (October 2022 to February 2023), the impact of our SEO strategy was clear across every key metric:

Traffic Growth

64% increase in organic traffic — monthly organic users grew from 340 to 560.

Keyword Growth

91% increase in indexed keywords — from 350 to 670 total keywords.

390% increase in page-one rankings — first-page keywords surged from 10 to 49, including terms like “Threatstream” and “USM Anywhere.”

Ranking Improvements

Core keyword rankings saw dramatic SEO performance improvements:

• “MDR Services”: Up 66 positions
• “Threat Intelligence Services”: Up 55 positions
• “XDR Solutions”: Up 70 positions

Lead Generation

These traffic and ranking improvements directly led to an increase in qualified inbound leads, which was the client’s primary business objective.

‍

This engagement reinforced several critical lessons about SEO in the cybersecurity space:

• Prioritize BoFU content for quick wins. Service pages targeting high-intent terms like "MDR services" went live first, which set up the organic traffic growth that followed; monthly organic users rose from 340 to 560 in five months.
• A full-funnel keyword strategy builds compounding authority. Targeting ToFU, MoFU, and BoFU keywords together took page-one keywords from 10 to 49 and strengthened rankings across the board. 
• Technical SEO is foundational. Fixing broken links, improving site speed, and optimizing metadata removed barriers that were preventing Google from properly crawling and ranking the site, so the content work could actually show up in search results. 
• Competitor analysis uncovers hidden opportunities. Mining competitor sites for keyword gaps revealed high-value terms that Castra wasn’t targeting, including niche product keywords that drove qualified traffic.
• Internal linking amplifies content performance. Topic clusters with logical internal links improved navigation and crawl efficiency, helping new pages rank faster. 
• Trending topics can accelerate early results. Timely queries like OpenSSL vulnerability news captured time-sensitive traffic while evergreen content matured.
• Build for the search results of today. This engagement predates AI Overviews and other LLM search engines, but the same fundamentals matter more now. Clear service pages, authoritative answers to buyer questions, and a strong technical foundation are what earn that, in search results or AI-generated ones.

“Amplifyed was a breath of fresh air from our very first call. Since then, our organic traffic has never been better.”

The cybersecurity industry presents unique SEO challenges that many agencies aren’t equipped to handle.

Cybersecurity SERPs are dominated by well-funded competitors with deep content libraries and strong domain authority. By the end of 2026, spending on information security is set to rise to more than $244 billion, an 11.6% increase. 

The buyer journey is complex, often involving multiple decision-makers and long sales cycles. And the technical nature of the products means that content needs to be authoritative and accurate to build trust with a highly informed audience. Gartner finds that 67% of B2B buyers prefer a rep-free buying experience, meaning your site content directly sells to your ideal customers.

This case study demonstrates that even in a competitive vertical like cybersecurity, a structured SEO strategy focused on keyword intent, content quality, and technical excellence can produce meaningful results in a short timeframe.

Whether you’re a managed security services provider, an endpoint protection vendor, or a GRC platform, the fundamentals are the same: understand your buyer’s search behavior, create content that addresses their needs at every stage of the funnel, and ensure your site’s technical foundation supports discoverability.
