Speed and caching plugins

# Speed you build in, rather than bolt on

Caching and optimisation plugins make WordPress pages faster by storing ready-made copies, compressing files and delaying scripts. On a rebuilt site, pages are light from the start: only the code each page needs, sensibly sized images, and pages served ready to read.

## What they typically handle

Speed plugins typically cache pages, minify and combine CSS and JavaScript, lazy-load images and delay third-party scripts.

Google's Core Web Vitals measure loading, responsiveness and visual stability, and Google describes them as part of page experience.[1]

Google says its core ranking systems look to reward content that provides a good page experience.[2]

## On a rebuilt site

### Pages served ready to read

Public pages are rendered on the server, so visitors and search engines receive the content straight away rather than waiting for scripts to build it.

### Only the code each page needs

Without a theme and builder loading features for every page, pages ship less code. Larger features are loaded only where they are used.

### Images sized for the screen

Images are compressed, given dimensions to avoid layout shifts, and loaded lazily below the fold.

### Measured, not assumed

We check key pages with Lighthouse or PageSpeed Insights before launch and after significant changes, and share the results with you.

## What we ask you first

- Which pages feel slow today, and on which devices?
- Which third-party scripts (chat, analytics, ads, embeds) does the site load?
- Do you have current Core Web Vitals data in Google Search Console?

Questions

## Common questions

**Will a faster site rank higher?**

Speed is part of page experience, which Google says its ranking systems look to reward. Paired with useful content, a fast site gives you the strongest footing in search, and every visitor gets a better experience.

**Do I need a caching plugin on the new site?**

No. There are no plugins. Caching and asset handling are part of how the site is built and served.
