Next.js performance and technical SEO
Is your Next.js site slow or hard to find technically? I improve load times, Core Web Vitals, rendering, and SEO signals, with a focus on measurable gains rather than cosmetic tweaks.
What problem does this solve?
Slow pages cost conversions. Users notice poor Core Web Vitals and heavy JavaScript bundles immediately, and so does Google. LCP and INP are usually the biggest pain points.
Technical SEO in Next.js requires more than meta tags: canonicals, indexable structure, fast server responses, and smart rendering. Without that foundation, content marketing just mops the floor with the tap still running.
The gains often sit in concrete choices: images, caching, data fetching, and less client-side weight. Not in another plugin or a generic 'speed optimization'.
I work evidence-based: measure first, then tackle the biggest bottleneck, then lock in the gain so the next feature doesn't undo it.
Who is this for?
- Teams with disappointing Lighthouse or CrUX scores
- Marketing and product owners who need faster landing pages
- Companies with Next.js sites that index poorly or feel slow
- Platforms where performance is a direct business problem
- Teams that just shipped a feature release and saw scores drop
What I concretely improve
- Core Web Vitals (LCP, INP, CLS) and load time
- Rendering and caching strategy
- Image, font, and bundle optimization
- Metadata, canonicals, sitemap/robots, and structure
- A measurement plan so improvements are provable
- Practical guidelines so new features don't undo performance gains
Approach
- 01
1. Measuring
Lab and field data where available, plus the codebase. We note the top pages and the biggest bottlenecks.
- 02
2. Biggest impact first
Fixes with the most gain come first: hero/LCP, slow APIs, overly heavy client bundles, or poor images.
- 03
3. Technical SEO signals
Canonicals, metadata, indexability, and structure are addressed where relevant for your pages.
- 04
4. Locking in the gains
Improvements are captured in code and monitoring, so scores don't drop again after the next release.

Example from practice
Performance work often comes down to a mix of rendering decisions, heavy client bundles, and slow data flows. On product and platform pages, you notice that immediately, both in feel and in vitals. The result needs to be noticeable to users and visible in measurements, not just a theoretical score.
