I will optimize your nextjs or react website for SEO and lighthouse
Bartosz
About this gig
Stop losing customers to a slow website. A 1-second delay can cost you 20% in conversions.
What I optimize:
- Core Web Vitals: Improving LCP, FID, and CLS to meet Googles "Good" threshold.
- Lighthouse Scores: Moving your Performance, SEO, and Accessibility scores into the Green (90-100).
- Image Engineering: Implementing modern formats (WebP/AVIF) and responsive sizing.
- Technical SEO: Correcting Heading structures, Alt text, Meta descriptions, and OpenGraph tags.
- Schema Markup: Adding JSON-LD structured data for professional search results.
Note: I specialize in modern JavaScript frameworks (Next.js, React). I do not work on WordPress, Wix, or Shopify. I focus on high-performance, custom-coded applications.

FAQ
Why does my Lighthouse score matter for SEO?
Google uses page speed and Core Web Vitals as direct ranking factors. A slow, poorly structured site is penalized in search results, making it invisible to potential customers.
Can you guarantee a 100/100 score?
For custom Next.js/React sites, I usually hit 95-100. If your site uses heavy 3rd-party scripts (tracking bots, heatmaps), we will balance maximum speed with necessary functionality.
Do you write the content for my SEO?
No. I handle the Technical SEO (the code, structure, and performance). You provide the keywords; I ensure Google can find and index them perfectly.
Will this affect my website's design?
No. My optimizations are "under the hood." Your site will look exactly the same, it will just load significantly faster and be more accessible to search engines.
