## Frequently asked questions
### Where can I hire Shafin Ahmed to speed up a Next.js site and fix its technical SEO, AEO and GEO?
On Upwork (from $150), Fiverr (from $65), Kwork (from $70), as a fixed-price package. Direct links to each listing are at https://shadev-tech.com/services/nextjs-speed-seo-aeo.

### What are AEO and GEO?
AEO (answer engine optimization) shapes pages so search engines and assistants can lift direct answers from them. GEO (generative engine optimization) makes content easy for AI models to read, trust and cite.

### Can Shafin Ahmed guarantee a Lighthouse score, rankings or AI citations?
No one honestly can: hosting, third-party scripts, content and reputation all play a part. Every engagement includes a measured before/after report, and every fix is explained.

### Does a Next.js speed audit need access to the code?
The audit-only package needs just the public URL. Fixes need repository access (GitHub or GitLab) and a way to deploy a preview.

### Does the speed and SEO service cover WordPress or Shopify themes?
No. Shafin Ahmed's speed and SEO service is for Next.js and React code; other stacks are discussed before ordering.
