Hosting Glossary
What is Lazy Loading?
Lazy Loading in plain English — the definition, the analogy, and why it matters to anyone who runs a website.
The short answer
Lazy loading defers offscreen images and embeds until the visitor scrolls toward them — first paint stops paying for the footer.
The sections below unpack it properly — how it works, why a site owner should care, and a concrete example of it in the wild.

Humans if you're stuck
Native browser support (loading=lazy) made it a default rather than a technique; plugins extend it to backgrounds and iframes with placeholders and tuned thresholds.
Its one sharp edge: the above-fold hero must stay eager — lazy-loading the LCP element delays the exact metric the practice exists to improve.
A picture that makes Lazy Loading stick
A gallery lighting rooms as visitors approach rather than the whole building at opening — the entrance blazes instantly, and the unvisited wings never burn a bulb.
Analogies simplify, of course — but this one holds up well enough to reason with, and reasoning is the point of a glossary.
Why it matters to a site owner
On image-rich pages it's among the cheapest vitals wins available — initial payloads shrink by the weight of everything below the fold, at zero visual cost when thresholds are sane.
You don't need to operate this layer daily — you need to recognise it when it's the explanation for something, which is exactly when this page pays for itself.
Lazy Loading in the wild
A portfolio's forty images load as four — the visible fold immediately, the rest resolving just ahead of the scroll; the bounce-deciding first seconds carry a tenth of the weight.
Ordinary, once seen — which is the point: most hosting concepts are simple machinery wearing intimidating names.
The HostingAlly angle
On our hosting this mostly takes care of itself — the platform applies the sensible defaults, and the panel exposes the controls when you want them. The concepts worth knowing next: Core Web Vitals, Cache, CDN and Theme.
Support is answered by real people around the clock — including the questions other hosts call out of scope.
A glossary from people who answer tickets
Every confusing term in hosting eventually becomes a support ticket — so we defined the hundred most common ones properly, once, in the plain English we'd use on the phone.
Annual plans include your first year of domain registration on us.

Examples reference the hosting you'd actually use, not abstract diagrams.
The next reads, mapped
This entry connects to Core Web Vitals and Cache — concepts travel in packs, and the pack is linked.
Honest about what you can skip
Most terms are recognise-level, not operate-level — the glossary says which is which.

FAQ
Your questions, answered
Does lazy loading hurt image SEO?
Native lazy loading is fully crawlable — Google renders and indexes deferred images. The obsolete risk belonged to old JavaScript-only schemes; the attribute-based standard is explicitly search-safe.
Why is my hero image slow since enabling lazy loading?
It got caught in the net — exclude above-fold images (most plugins auto-skip the first few) so the LCP element loads eagerly. Lazy is for below the fold; eager is for the opening frame.
Will you move my existing website for free?
Yes — open a ticket with your current host's access details and we handle the whole move: files, databases, email and configuration, verified by you before DNS switches. The old site keeps serving until the new copy takes over, so visitors never see a gap.
Can I host more than one website on a plan?
On the Pro tier and above, yes — multiple sites with their own domains, email and SSL under one account. If the extra sites belong to clients rather than you, reseller hosting gives each one proper isolation instead.
What happens to my data if I cancel?
Your site and files remain yours — download a full backup from the panel any time, before or during cancellation. Domains stay registered to you for their paid term and can transfer to any registrar after the standard 60-day window.
Where are your servers located?
Our hosting infrastructure runs from European datacentres with London at the core, behind server-level caching that keeps cached pages fast worldwide. For most sites, platform quality — NVMe storage, LiteSpeed, sensible server density — matters far more than the datacentre's postcode.
Are backups included, and can I restore them myself?
Daily automatic backups are standard, restorable from the panel in minutes — files, databases or both, at 3am without a ticket if that's when you need it. For extra cover, you're welcome to run your own offsite copies alongside.

CDN (Content Delivery Network)
A CDN caches your site's assets on servers around the world, serving each visitor from the nearest edge instead of your origin.
Core Web Vitals
Core Web Vitals are Google's user-experience metrics — loading (LCP), interactivity (INP) and visual stability (CLS).
VPS Hosting
KVM virtual servers with root access, DDoS protection and flat pricing.
Web Hosting
NVMe cPanel hosting with free SSL, migration and a free first-year domain.
