## Questions people ask

### How much does a website cost?

It depends on the number of pages, custom features and integrations. A portfolio or landing site is a small project; a web app with accounts and a database is a larger one. Zaid sends a scope and an estimate within two days of your brief.

### Is Next.js good for SEO?

Yes. Next.js renders pages on the server or at build time, so search engines and AI crawlers receive the complete HTML, and it has built-in metadata, sitemaps and image optimisation. Zaid Sayyed's own 300+ page site runs on Next.js, with structured data on every page.

### Next.js or WordPress for a business website?

WordPress suits teams that want a familiar editor and plugins. Next.js suits custom sites and web apps where speed, design freedom and features matter, and it can still use a CMS for editing. Zaid Sayyed builds with Next.js and React and will say if WordPress fits you better.

### Will my site rank on Google and show up in AI answers?

Nobody can promise rankings, but the technical side can be done right: fast pages, structured data, a sitemap, clean headings and answers written to be quoted. That is how zaidsayyed.in is built, and its pages are indexed by Google and read by AI crawlers.

### Why is my website slow?

The usual causes are heavy images and video, too much JavaScript, slow hosting and render-blocking scripts or fonts. Zaid Sayyed measures first with Lighthouse and real traces, fixes what actually costs time, and shows the before and after. He cut his own site's hero from 46 MB to 4 MB.

### Do you also build mobile apps?

Yes. Zaid builds Flutter apps for Android and iOS too, so a product can have its website and app built by the same developer with one shared backend.
