SEO Case Study: How a Certification Platform Increased Exam Registrations by 280%
In March 2025, a Princeton based certification platform partnered with Goforaeo because exam registrations from Google were not steady. They had respected certifications, good pass rates, and strong instructors, but organic search was not bringing enough new candidates each month. Paid ads and partnerships were covering the gap, yet the team wanted a dependable flow of registrations through SEO.
This case study shares the exact 2025 timeframe, the Princeton location angle, the monthly SEO actions completed, the tools used, and clear before vs after proof showing a 280% increase in exam registrations from organic search.
Client Snapshot: Princeton, New Jersey
The client is a certification platform headquartered in Princeton, New Jersey, offering exam based certifications in project management, business analysis, cybersecurity fundamentals, and compliance tracks. They also ran proctored exam sessions and optional prep workshops near Princeton and nearby areas like Plainsboro, West Windsor, and Lawrence Township, which allowed local SEO to support national intent without sounding forced.
They had a solid website, but the SEO structure was weak. Many pages were overlapping, some certification pages were too thin, and the blog content was not connected to exam registration pages. That meant Google did not clearly understand which pages should rank, and visitors often did not reach the registration step.
What Counted as an Exam Registration
We tracked registrations that were actually valuable to the business, not soft conversions. A registration counted when a user completed the exam registration checkout and received confirmation.
We also tracked supporting actions that often lead to registrations:
- “Exam schedule” page visits from organic
- “Register now” button clicks that reached checkout
- Calls and emails from organic about exam dates
- Candidate quality signals in the CRM

How We Set Up Clean Tracking
We fixed tracking first so reporting stayed honest. Exam registrations can be hard to measure if tracking breaks at checkout, so we verified registrations in both analytics and payment logs.
Tracking setup included:
- GA4 conversion event for completed registrations
- Google Tag Manager for checkout event consistency
- Google Search Console for query and page growth tracking
- Payment and CRM logs to validate monthly registration totals
Baseline Before SEO: March 2025
In March 2025, the platform had some brand traffic and some direct visitors from partners, but non brand SEO performance was weak. Several certification keywords were sitting on page two, and the pages that ranked did not clearly answer questions candidates ask before registering. Many users landed on informational posts and left without seeing exam dates or the registration path.
We also found that key pages were competing with each other. Two or three pages were often targeting similar certification terms, which split rankings. The registration flow also had friction, especially on mobile, and that reduced registrations even when traffic came in.
Baseline Metrics: March 2025
These were the baseline numbers from March 2025, used as the “before” reference.
- Organic sessions: 7,300
- Search Console clicks: 3,180
- Average CTR: 2.4%
- Keywords in top 10: 21
- Keywords in top 3: 5
- Exam registrations from organic: 75
- Organic session to registration rate: 1.03%
Strategy: The SEO System We Built
We treated this as a conversion focused SEO project, not just a ranking project. Exam registration intent is high, but candidates need clarity on eligibility, fees, exam dates, format, and what happens after registration. Our strategy was built to answer those questions early and guide users smoothly into the checkout.
We worked in five connected layers so growth stayed stable.
- Technical cleanup and index clarity
- Strong certification pages that match search intent
- Support content clusters tied to each certification
- Princeton local trust pages tied to proctoring and workshops
- Conversion improvements in registration flow
Keyword and Page Mapping
We built one main page per certification and one main page per intent type, then used supporting pages to strengthen them. This removed overlap and made it easier for Google to rank the correct pages.
Keyword groups we targeted:
- Certification intent: “cybersecurity certification exam”, “business analysis certification exam”
- Schedule and registration intent: “exam dates”, “register for certification exam”
- Eligibility intent: “requirements”, “who can take the exam”
- Local intent: “Princeton exam center”, “Princeton proctored certification exam”
Tools Used
We used a tool set that supported both execution and clean proof.
Tools used:
- Google Analytics 4: conversions, funnels, checkout tracking
- Google Tag Manager: stable event setup for registrations
- Google Search Console: queries, clicks, CTR, indexing
- Screaming Frog: technical audits, duplication checks, internal linking
- Ahrefs: keyword research, competitor gaps, link monitoring
- Looker Studio: monthly reporting dashboard
- PageSpeed Insights and Lighthouse: speed and Core Web Vitals
- Hotjar: drop off points and form behavior tracking

- CTR: 2.4%
- Top 10 keywords: 21
- Registration rate: 1.03%
After in October 2025:
- Organic exam registrations: 285

Proof of 280% growth:

- Net increase: 210 more registrations per month
- Percentage increase: 280%
Why This Worked: Simple Explanation
This worked because we made the site clearer for both Google and candidates. Google stopped seeing overlapping pages and started seeing one strong page per certification plus helpful support pages. Candidates stopped feeling uncertain because the key pages answered the exact questions that usually block registrations.
The second reason was conversion improvement. We did not rely on rankings alone. We improved the registration flow, reduced friction, and made exam dates and pricing clearer. When traffic and conversion rate rise together, registrations grow much faster.
Key Takeaways for Certification SEO in Princeton
If a certification platform wants SEO growth, the biggest wins come from building clear certification pages, supporting them with real prep and requirements content, and making the registration path easy.

Key lessons from this campaign:
- One clear page per certification improves rankings and reduces overlap
