Pages take too long to appear
Visitors notice the delay before they understand its technical cause.
WEBSITE PERFORMANCE
A slow website is usually a symptom.Find the cause.
Website performance can deteriorate gradually.
More scripts are added. Images get larger. Plugins accumulate. Tracking tools multiply. A page builder becomes heavier. New integrations arrive. The website still works, but everything begins to feel slower.
MiBanana investigates what is actually affecting the site, identifies what is worth fixing and helps you decide whether targeted optimisation or a wider rebuild makes more sense.
Speed affects more than a performance score.
Visitors experience performance before they understand the technical reason behind it.
Content moves while they read
Visual instability interrupts the experience and makes pages harder to use.
Buttons respond slowly
A laggy interface makes even simple actions feel harder.
Mobile feels heavier
The mobile experience can feel slow even when the desktop site seems fine.
Performance can also affect
- User experience
- Mobile usability
- Conversion journeys
- Search performance
- Accessibility
- Perceived quality
- Advertising landing pages
- Content engagement
- Internal website management
- Cost and complexity of future development
Performance is part of the website itself, not simply a number generated by a testing tool.
Why is my website slow?
There is rarely one universal answer. Finding the cause comes before deciding on the fix.
Images
Large or inefficient image files add weight to every visit.
JavaScript
Too much code can delay useful interaction.
Third-party scripts
External tools add requests and work to the page.
Fonts
Font files and loading choices affect both speed and rendering.
Plugins and page builders
Accumulated features can increase frontend overhead.
Hosting and server response
The server and delivery setup affect how quickly a page begins loading.
CMS architecture
The way content is managed and served shapes the technical baseline.
External integrations
Connected services can add weight or waiting time.
Website architecture
The overall implementation determines what needs to load and when.
Performance is not one number
A perfect score is not the objective. Tools such as Lighthouse and Core Web Vitals can be useful parts of the process, but they are evidence, not the entire strategy.
We look at the full experience behind the score.
Experience
Loading performance, responsiveness and visual stability.
Browser work
Network requests, JavaScript execution and third-party resources.
Asset delivery
Image delivery, font loading, caching behaviour and server response.
Testing context
Mobile conditions and page-specific differences.
Fix what matters
Not every warning deserves the same amount of work. We prioritise issues based on likely visitor impact and the practical value of making a change.
Visitor impact
How much does the issue affect people using the website?
Reach
How often does it occur, and how important are the affected pages to the business?
Practical effort
What will it take to fix, and what technical risk does the change involve?
Durability
Will the improvement remain maintainable, or is the problem likely to return?
Dependencies
Do connected tools or other systems affect the solution?
Platform fit
Can the current platform support a practical fix?
Optimise or rebuild?
We do not recommend rebuilding automatically.
Targeted optimisation
Makes sense when the underlying website is sound and the problems are relatively isolated.
Performance-focused rebuild
May make sense when the site carries years of technical debt, page-builder overhead, plugin dependency or an architecture that has become the constraint.
Performance is part of a wider website decision.
Redesign
A slow website does not always need a new design. If speed is only one part of a larger problem, a redesign may be more relevant.
Migration
Changing platforms can improve the technical foundation, but migration has a cost. Consider whether the expected performance and maintenance benefits justify the move.
Astro
Astro can be a strong option, but performance is not automatic. Large images, excessive scripts, unnecessary third-party services or poor frontend decisions can still create a slow website. Astro is a technology option, not the performance service itself.
Search
Search visibility and performance are connected, but they are not the same thing. Improving site speed does not create a guaranteed ranking increase.
How Website Performance works
- 01
Understand the problem.
- 02
Establish a baseline.
- 03
Identify the main causes.
- 04
Prioritise.
- 05
Agree the approach.
- 06
Implement.
- 07
Validate.
- 08
Document the outcome.
What success looks like
Different projects need different evidence. Depending on the website and scope, useful validation could include:
We do not invent benchmark numbers or promise outcomes before the work has been measured.
Before and after
Laboratory tests and real-user performance data where available.
Core Web Vitals
Page weight, request counts and JavaScript behaviour.
Asset and service impact
Image delivery and the effect of third-party resources.
Production checks
Server response, mobile testing and functional validation.
Performance should survive after the project ends.
Where MiBanana is responsible for the website architecture, we aim to make performance-related decisions understandable and sustainable.
Website Performance projects typically start from €4,000.
The final scope depends on the actual website and work involved.
Scope can depend on
- Website size and platform
- Page-builder architecture
- Number of templates
- Third-party services and integrations
- Hosting and CMS
- Custom functionality
- Whether redesign or migration is required
- Availability of analytics and performance data
FREQUENTLY ASKED QUESTIONS
Straightforward answers about website performance.
Common contributors include oversized images, excessive JavaScript, third-party scripts, plugins, page builders, fonts, hosting configuration, CMS overhead and inefficient frontend architecture.
No. Lighthouse is a diagnostic and validation tool, not a contractual result.
They are metrics used to evaluate important aspects of page experience, including loading, responsiveness and visual stability.
Performance can contribute to a stronger technical foundation, but speed alone does not determine rankings.
Yes, depending on the website and the underlying cause.
Not necessarily.
No. Architecture and implementation matter.
Sometimes. Some third-party services have an unavoidable performance cost.
They can, but performance needs to be protected.
Potentially.
The output depends on the engagement. Performance work normally requires a baseline, identification of significant issues and validation of agreed changes.

Find out what is actually slowing the website down.
If performance has become a problem, the first decision is not which optimisation plugin to install.
It is understanding the cause, what it affects and which improvements are worth making.
