Overview
SEO isn’t just about expertise—it’s about experimentation and learning. While theories and best practices exist, the real breakthroughs happen through hands-on testing.

Table of Contents
This case study documents a small experiment I conducted on a low-traffic food niche website. The site initially had:
✅ 200 monthly clicks
✅ Low CTR (0.8%)
✅ Poor engagement metrics
Instead of making major content changes, I focused on UI/UX improvements, semantic structuring, and small on-page tweaks. The results? Traffic grew 4x, and CTR improved significantly.
Let’s break down the exact steps taken, the strategy behind them, and what we learned.
Background: The Site & Initial Observations
This was an aged domain in the competitive food niche, but it wasn’t performing well due to:
🔹 Poorly structured landing pages
🔹 Unoptimized pillar content
🔹 Low engagement due to weak UI/UX
🔹 No strategic internal linking
I didn’t have time to manually optimize every aspect, so I took a minimalist, high-impact approach—guiding just one team member to implement these changes.
SEO Experiment: The Strategy & Execution
1️⃣ Revamping the Homepage for Engagement & CTR
Hypothesis: A better first impression with clear navigation and brand familiarity would increase engagement and reduce bounce rates.
✅ Added a large infographic banner featuring:
- Niche categories
- Key pricing data upfront
✅ Recreated UI/UX to match major competitors
✅ Placed primary CTA above the fold
Outcome:
✔ Increased time on page
✔ Boosted CTR due to clearer content hierarchy
Why It Worked: Google favors engagement signals—better UI/UX lowers bounce rates and improves user retention.
2️⃣ Semantic Optimization of Pillar Pages
Hypothesis: A structured semantic site architecture would improve crawlability, internal linking, and keyword distribution.
✅ Reorganized site hierarchy with a structured format:
Before:
- /category1-page
- /random-page
- /unclear-subcategory
- /product1-page
After:
- /main-category
- /main-category/subcategory1
- /main-category/subcategory2
- /main-category/product1
Example for a banking website structure:
- /bank
- /bank/atm
- /bank/creditcard
- /bank/account
✅ Used internal linking to connect relevant pages logically.
Outcome:
✔ Improved keyword rankings for broader terms
✔ Increased crawl efficiency and indexing speed
Why It Worked: Google’s algorithms favor contextually linked content—a structured taxonomy improves site discoverability and ranking potential.
3️⃣ On-Page Optimization for Better Relevance
Hypothesis: Improving content structure, n-grams, and internal relevance would enhance semantic SEO signals.
✅ Conducted a content audit to find underperforming pages.
✅ Updated existing articles with relevant n-grams and LSI (Latent Semantic Indexing) keywords.
✅ Used internal linking to distribute link equity to important pages.
Outcome:
✔ Increased keyword coverage & visibility
✔ Older content started ranking higher without new backlinks
Why It Worked: Google understands content contextually—improving semantic signals can boost rankings even without major content additions.
4️⃣ Color Scheme & UX Adjustments for Brand Trust
Hypothesis: Aligning the site’s color scheme & design with top competitors would make it instantly recognizable & trustworthy.
✅ Analyzed color schemes of major brands in the niche.
✅ Modified the site’s UI to match industry leaders.
Outcome:
✔ Improved brand recognition
✔ Increased user retention & interaction
Why It Worked: A familiar visual identity reduces psychological resistance—users trust what looks like an established brand.

📈 Traffic Growth: Increased from 200-250 clicks/month to 1,060+ clicks/month.
