Over 70% of your visitors access your website via mobile devices. The smoother your website loads, the less likely visitors are to bounce before the page even appears. Furthermore, Google Search uses actual mobile browsing experience as a ranking factor.
With Kanorio, you don't need to install any caching plugins. We accelerate your website at the infrastructure level using server-side rendering, Cloudflare global edge caching, automatic image optimization based on screen size, and deferred loading for third-party tracking scripts (see for technical details). We also perform automated health checks in the background, which you can view under "SEO › Website Speed".
Speed measurements are performed automatically in the background—no manual action is required:
In "SEO › Website Speed," you will see two different assessment cards. Many site owners ask: "Why does my site feel super fast on my phone, but the speed score below is only in the 60s?"
The reason is that these two cards represent completely different measurement methods:
| Comparison | 1. Google Page Experience (Real User Experience) | 2. Page Speed Score (Lab Simulation) |
|---|---|---|
| What is this card? | Google collects the actual speed experienced by real visitors who accessed your website via Chrome on mobile devices over the past 28 days (Chrome UX Report). | Google servers simulate a mid-range older mobile device opening your page once under a throttled slow network to generate a diagnostic score (0 to 100). |
| Does it affect Google rankings? | Yes, this is the data Google Search actually uses for ranking. | It does not directly affect rankings. It serves as an "X-ray" to help you identify oversized images or resource-heavy embeds under strict conditions. |
| When should I check this card? | Once your website has accumulated enough traffic and the card displays "Passed" or a specific time, use this card as your primary reference. | For new websites or those with low traffic, the first card may show "—" (insufficient data). In this case, refer to the diagnostic suggestions and long-term trends on this card. |
Once your site accumulates enough real mobile visitor data, the first card will display three core metrics. If all three meet the "Good" standard, you will see a green "Passed" status:
| Metric | What it means | Good Standard |
|---|---|---|
| Largest Contentful Paint (LCP) | The time it takes for the largest main image or heading to fully appear after a visitor opens the page. | Under 2.5 seconds (Over 4 seconds is poor) |
| Interaction to Next Paint (INP) | The time it takes for the screen to respond after a visitor taps a button, expands a menu, or clicks a link. | Under 200 milliseconds (0.2 seconds) (Over 500 milliseconds is poor) |
| Cumulative Layout Shift (CLS) | Whether text or buttons jump unexpectedly during page loading, causing visitors to click the wrong place. | Stable (No unexpected shifts) |
The second card lists simulated scores for your pages (90+ is Good, 50–89 is Needs Improvement, 49 or below is Poor). It also highlights the primary issue directly below the page name (e.g., "Loads smoothly" or "Takes about 8 seconds to appear").
When the system identifies that a page is slow due to factors you can improve by adjusting content, the details panel will display "Things you can do" along with a "Go to Editor" button (a reminder will also appear in ; website speed itself does not deduct from your health check score):
| System Prompt | Why it slows down the site | Recommended adjustments |
|---|---|---|
| 1. Large hero image | The top of the page (above the fold) contains an image with a large file size or high resolution, which takes longer to download on mobile devices over slow networks. | Click "Go to Editor" to replace the hero image with a more optimized file (recommended under 1.5 MB), or choose a layout that doesn't require a full-screen image. |
| 2. Resource-heavy embeds | The page contains embedded YouTube videos, Instagram posts, external maps, or third-party widgets. These platforms execute heavy scripts during loading, consuming mobile device resources. | Reduce the number of external embed modules on the page. For videos or external content, use a "clear thumbnail + button to view" approach and keep the actual embed on a sub-page. |
| 3. Layout shifts during loading | The page contains external embeds without fixed heights (common in third-party forms, maps, or dynamic posts). When they load slowly, they push the text below them downward. | Check the embed modules in the editor or move these dynamic embeds further down the page to avoid disrupting the visitor's initial reading experience. |
No, you don't. While external tracking scripts are third-party, Kanorio treats GA4, Google Tag Manager, and Meta Pixel as essential tools for running a website. We automatically optimize these scripts at the infrastructure level to "load in the background only after the above-the-fold content is rendered or when the visitor starts scrolling." This prevents them from competing with your homepage images for bandwidth, and you won't be asked to remove them in our speed recommendations.
This means our system diagnostics show that your image sizes, layout, and embedded content are all optimal! The score is low because Google's lab environment simulates a "mid-range mobile device on a slow mobile network" while loading full multi-language fonts. Real visitors on modern devices and networks will experience much faster speeds. You don't need to change anything; our engineering team continuously optimizes font delivery and transmission efficiency at the infrastructure level.
Lab simulations involve a real connection from Google's test servers to your site. Network routing fluctuations and test server load can cause minor, natural variations. As long as your "Homepage Score Trend" doesn't show a sudden, massive drop after an update, there is no need to worry.
