SEO Case Study
A documented example that shows how specific search optimisation actions led to measurable changes in traffic, rankings, leads, or conversions.
If you have ever presented a case study without a baseline or timeframe, you already know it looks like a sales pitch, not evidence.
Key points
- Always include a baseline metric and a specific date range so the change is verifiable.
- Show both percentage change and absolute numbers to give full context.
- Mention at least one obstacle or lesson learned to avoid sounding promotional.
- Tie results to business goals like leads or conversions, not just rankings.
- Use screenshots from Google Analytics or Search Console to support your claims.
200% more leads in 90 days: how 20 pages were rewritten
A B2B SaaS company improved organic leads from 50 to 200 per month over 90 days by rewriting 20 landing pages with keyword-focused content and fixing technical errors. The case study included a baseline of 50 leads, the exact pages changed, and screenshots from Google Analytics showing the trend. The headline highlighted the result first, then explained the method. This made the story credible and actionable for readers.
Three things a case study is not
- Not a sales pitch A credible case study includes challenges and setbacks, not just wins. Omitting obstacles makes it feel promotional and less trustworthy, unlike genuine SEO success stories that share failures.
- Not a ranking report Rankings alone do not prove business impact. Tie every keyword ranking change to traffic, conversions, or revenue to show real value.
- Not a guarantee What worked for one site may not work for yours. Case studies illustrate a method, not a promise of identical results.
Four ways it goes wrong
- Missing baseline Without a starting point, the reader cannot judge the improvement. Always state the metric value before the intervention.
- Cherry-picked metrics Showing only the best-performing keyword while ignoring overall traffic loss misleads. Present a balanced view of the data.
- No timeframe Results without dates are meaningless. Specify the exact start and end dates of the measurement period so the reader can assess recency and relevance.
- No lessons learned Omitting what went wrong or what you would do differently makes the case study feel incomplete and less useful for building an SEO portfolio.
Three elements every case study needs
- Baseline and timeframe State the starting metric and the exact period over which the change occurred. This allows readers to assess the validity of the results.
- Exact interventions List every action taken, from content changes to technical fixes. Vague descriptions make the case study impossible to replicate.
- Business outcome Translate ranking or traffic changes into leads, conversions, or revenue. This connects SEO work to real business value and supports SEO reporting efforts.
