Your site stays where it is. Traffic routes through WebSpeed with a DNS change and pages arrive optimized — nothing installed, nothing in your plugin list to conflict with, nothing a core update can undo. And what we fix isn't a checklist: across the 64 WordPress sites we audited, the same handful of bottlenecks came back again and again.

Each one is independent and can be switched off for your domain — nothing here is all-or-nothing.
The CSS the first screen needs is inlined; the rest stops blocking. The browser paints on the first response instead of waiting out a chain of stylesheets.
The largest above-the-fold image is preloaded at high priority; images further down wait until they approach the viewport.
Below-the-fold sections are skipped until they're needed, so a long page costs about what its first screen costs.
We read each image's true aspect ratio server-side and put it in the markup, so the browser reserves the right box before the file arrives.
JPEG and PNG become WebP on the fly, animated GIFs become animated WebP, and icon fonts are subset to the glyphs the page actually uses.
An optimization you cannot undo is a risk, not a feature. Each of these is a decision you keep after the site is live on WebSpeed.
Each one is independent. If something doesn't suit your WordPress theme, it can be disabled for your domain alone and everything else keeps working.
On a tuned profile we measure each optimization against your own pages and drop the ones that do not earn their place there.
Your audit page re-runs both measurements on demand, so "did it help" stays a number you can pull rather than a claim you have to take.
WebSpeed sits in front of your site, not inside it. Revert the DNS record and your original site serves again, unchanged — nothing to uninstall.
In progress: a dashboard where you flip these yourself and follow each page's scores over time. Today it is a message to us and we apply it to your domain.
Not the usual tips — this is what our filter logs actually recorded across the WordPress sites we have audited, ranked by how many of them had something to fix.
Measured across 61 WordPress audits · snapshot 2026-09-09
92%of sites
Near-universal on this platform, and untouched by a caching plugin. Every plugin and every builder queues its own stylesheet into the head, and the browser must fetch and parse all of them before it can paint a single pixel.
75%of sites
The largest image on the first screen — the one the visitor is waiting for — is fetched at the same low priority as everything else, so it queues behind assets nobody is looking at yet.
84%of sites
Long pages lay out and paint their whole length before the visitor has scrolled. On a phone that is most of the rendering cost spent on content that may never be seen.
330fixes on 30 sites
One of the two highest-volume defects we correct. Themes output images without width and height, so the browser can't reserve space and text jumps as each file lands.
Stored audits — the original page against the same page served through WebSpeed, on mobile and desktop. Not a demo build: these are the sites as they ship.
Real Google Lighthouse audits, original vs. WebSpeed Fast. The ring is the mobile PageSpeed after; “faster” is the Speed-Index ratio; “lighter” and CO₂ (≈0.15 g/MB per visit, Sustainable Web Design v4) come from the measured byte reduction. SEO / conversion / bounce are projections from the measured LCP improvement, not guarantees. Scores are per-page; yours will differ.
* Core Web Vitals are a Google ranking signal; the biggest lift is leaving the “Poor” zone (score < 50), scaled here by device search share.
** Akamai / SOASTA (2017): a 100 ms delay cost 7% of conversions across ~10 billion retail visits; scaled here to the measured improvement.
*** Akamai / SOASTA (2017): a two-second delay raised bounce rate by 103%; scaled to the measured improvement, site-specific.
Core Web Vitals have been a confirmed Google ranking signal since 2021. The biggest win is leaving the "Poor" band, where faster competitors get preferred.
— Google Search CentralConversion tracks load time closely — on Akamai’s retail numbers a delay of just 100 ms cost 7% of conversions. Shaving seconds is the cheapest funnel work available.
— Akamai / SOASTA, 2017Close a two-second gap and bounce rate roughly halves — Akamai measured those same two seconds raising it by 103%. A page that paints early keeps the visit a slow one loses outright.
— Akamai / SOASTA, 2017Transfer weight maps to emissions at roughly 0.15 g of CO₂ per MB. Cutting bytes is the one optimization that shows up on a sustainability report.
— Sustainable Web Design v4Each figure links to the page that publishes it. The studies measure what delay costs; read here as what speed returns. Industry benchmarks, not a guarantee for a specific site — the per-site numbers are the audits above, and yours is a free check away.
This is the first question every WordPress owner asks, and it deserves a straight answer instead of a sales one. The two tools work on different halves of the problem:
| Caching plugin | WebSpeed | |
|---|---|---|
| Fixes | when the response arrives | what’s in the response |
| Typical lever | skip PHP, re-serve stored HTML | reorder the critical path, prioritise, re-encode |
Blocking <head> | unchanged | unblocked |
| LCP image priority | unchanged | preloaded, high priority |
| Image formats | unchanged | WebP / animated WebP on the fly |
| Where it runs | inside WordPress | in front of it — nothing installed |
Cache the page and you get the same blocking head, faster. That’s one reason 92% of the sites we measured were still shipping one, despite most of them being large, professionally maintained sites with every reason to have tuned this already.
The two are complementary, not competing. Keep your cache plugin — it’s doing the half of the job we don’t.
The reason these problems persist isn’t ignorance — it’s ownership. Nobody is in charge of the finished page:
That’s why those plugins ship long compatibility lists and dozens of toggles: they’re negotiating with code they don’t control, from inside the same process.
WebSpeed skips the negotiation by working on the finished HTML, after WordPress has had its say. It sees what the browser sees — so it doesn’t need to know which plugin queued what, and nothing it does can be undone by an update.
It takes about a minute and needs nothing from you but the URL:
If your site is already fast, the audit says so. That’s a useful result too, and it costs nothing to find out.
No. The usual route is the proxy: your site keeps running where it runs, and traffic is routed through WebSpeed with a DNS change — nothing installed, nothing to conflict with your plugins, nothing that breaks on a WordPress core update. If you would rather not route traffic through us, there is an on-site integration we set up together with your developer instead. Same optimizations either way.
No — they work on different halves of the problem. A caching plugin mainly improves how fast your server answers. It does not change what that answer contains, and our measurements are all about the contents: 92% of the WordPress sites we audited were still shipping a render-blocking head, cache plugin or not. The two stack.
No. The optimizations are structural — load order, priorities, image formats, asset delivery. The markup that determines your design is left alone, and every audit ships a before/after screenshot so you can confirm it.
Each optimization is independent and can be switched off for your domain individually. On plans with a tuned profile we measure each one and keep only the ones that actually help your site.
The bottlenecks above aren't a function of traffic — they come from how WordPress themes and plugins queue their assets, which is the same on a 200-visit site as on a 200,000-visit one. The audit is free, so the honest answer is to measure yours rather than take ours.
The before/after check is free to run; it isn’t one of these plans. Choose a plan when you’re ready to make the speed-up permanent — or buy the report once and apply it yourself.
Subscriptions start with a 14-day free trial (Fast and Growth), then run for a minimum of 6 months — you commit only after the trial. Fast is priced by monthly visits; indicative launch pricing.
