What Is Web Hosting?

What web hosting is

Web hosting is the service that stores your website's files on a server and makes them accessible to anyone with an internet connection. Without hosting, your website has nowhere to live — it exists as files on a computer, but nobody can visit it.

When someone types your domain name into their browser, the hosting server receives that request and delivers your website's files to the visitor's device. This happens in milliseconds, thousands of times a day, every day your site is online.

Types of web hosting

Shared hosting

Your website shares a server with hundreds of other websites. It's the cheapest option — typically $5–$15/month — but performance suffers when other sites on the server experience traffic spikes. Fine for very small sites with minimal traffic.

VPS (Virtual Private Server)

A single physical server divided into isolated virtual servers. You get dedicated resources (CPU, RAM, storage) without sharing with other sites. Typically $20–$80/month. Good for growing businesses with moderate traffic.

Dedicated hosting

An entire physical server allocated to your website alone. Maximum performance and control, but expensive — typically $100–$500/month. Only necessary for high-traffic sites or applications with strict performance requirements.

Cloud hosting

Your website runs on a network of servers rather than a single machine. Resources scale automatically based on demand — you pay for what you use. Providers include AWS, Google Cloud, and Azure. Pricing varies by usage.

Static hosting / JAMstack

Purpose-built for static websites. Platforms like Vercel, Netlify, and Cloudflare Pages serve pre-built files from a global CDN. Often free for standard business sites. The fastest and most cost-effective option for sites that don't require server-side processing.

What to look for in a hosting provider

The factors that actually matter for business websites:

Uptime

How often your site is accessible. Look for 99.9% uptime or better. Anything below that means your site could be down for hours each month — losing visitors and damaging credibility.

Speed

Page load time directly affects user experience, Google rankings, and AI visibility. Your hosting should serve pages in under 2 seconds. CDN support (serving files from servers near your visitors) makes a significant difference.

Security

Free SSL certificates are standard and non-negotiable. Look for DDoS protection, automatic backups, and support for security headers. If you're running WordPress, look for managed hosting that handles security updates for you.

Australian data residency

If your business stores personal information, the Australian Privacy Act may require you to understand where that data is stored. Some hosting providers offer Australian-based servers. For static sites on global CDNs, data residency is less of a concern since you're typically not storing personal data on the hosting platform.

Support

When your site goes down at 2am, how quickly can you get help? Look for 24/7 support with actual technical staff, not just chatbots or ticket queues with 48-hour response times.

How hosting affects AI visibility

Your hosting choice affects AI visibility in several ways:

• Page speed — Slow servers mean slow pages, which can prevent AI crawlers from fully reading your site
• Uptime — If your site is down when an AI crawler visits, it can't index your content
• CDN coverage — Global CDNs ensure AI crawlers (which may be located anywhere) can access your site quickly
• SSL/HTTPS — AI tools prefer secure sources. A site without HTTPS is a negative signal

Recommended hosting by site type

• Static business sites — Vercel or Netlify (free tier is sufficient for most businesses)
• WordPress sites — WP Engine, Kinsta, or SiteGround (managed WordPress hosting with security updates included)
• E-commerce — Shopify (managed) or cloud hosting (AWS/GCP) for custom platforms
• Web applications — Cloud hosting (Vercel for Next.js, Railway or Render for other frameworks)
