Case studies are one of the strongest assets for an SEO or marketing agency.
Anyone can say they can grow traffic or leads. A case study shows how you did it.
A good case study tells a clear story.
Start with the client’s problem.
For example:
Low organic traffic
Poor website conversion
Weak local rankings
No clear funnel
Outdated website structure
Then explain what you changed.
This can include:
Keyword research
Technical SEO fixes
Landing page rewrite
Internal linking
Google Business Profile work
Content plan
CRO changes
After that, show the result.
Use clear numbers when possible:
Traffic increased by 48%
Leads grew from 6 to 19 per month
Keyword moved from page 3 to top 5
Form submissions doubled
Keep the case study honest. Do not exaggerate. Real numbers build trust.
A strong case study should also explain why the result happened.
This helps potential clients see your thinking process.
End with a clear CTA.
For example:
“Want a similar growth plan for your website? Book a free SEO review.”
Case studies turn your past work into future sales.
