What do the values of the Website Check mean?
The most important value is the speed score from 0 to 100. It combines several measurements and is divided by Google into three ranges:
- 90 to 100: fast
- 50 to 89: needs improvement
- below 50: slow
There are also five measurements. FCP shows when the first content appears, LCP when the main content has loaded, TBT how long the page is blocked, CLS how stable the layout remains, and the Speed Index how quickly the page builds up.
The values for accessibility, best practices and SEO are basic checks. They find standard technical errors, such as missing image descriptions or insecure connections, but do not replace a review of the content.
Why does loading time matter for enquiries and Google rankings?
People searching for a provider on their phone rarely wait long. If a page loads sluggishly, many visitors leave before they have seen your offering. Every enquiry lost this way has previously cost you advertising or groundwork.
Google also takes user experience into account. The so-called Core Web Vitals (LCP, INP and CLS) are a well-known signal, although one of many. A fast page does not turn weak content into a top ranking, but a very slow page can hold good content back. We do not promise particular rankings, but a fast, stable experience helps visitors and search engines alike.
For paid advertising it counts twice over: if you pay for clicks, you should not lose the visitors on a slow page. More on this under Google Ads.
What are the most common causes of slow websites, and what helps?
For most sites, a few causes are behind it:
- Images that are too large: photos straight from the camera or phone are often several megabytes. Suitable dimensions, modern formats such as WebP and delayed loading of images further down the page help.
- Too many plugins and extensions: every plugin loads its own code. Remove unused ones and combine functions.
- Weak hosting: an overloaded server responds slowly, however well the site is built. Switching to better hosting and caching often helps noticeably.
- Many third-party scripts: tracking, chat widgets, maps and external videos slow things down. Load only what is really needed, and only after consent or when required.
- Unnecessarily heavy fonts and designs: few font weights, lean code and a clean theme save loading time.
If a rebuild makes more sense than a patchwork of optimisations, you will find our service under Web design Vienna. A checklist for a fresh start is in the article Website relaunch checklist.
What does a good value really mean, and where does the test have limits?
A high score is a good sign, but not an end in itself. What matters is that your visitors quickly find what they are looking for and that this turns into enquiries. A page with 100 points that nobody understands achieves nothing.
The test has limits you should know about:
- It is a snapshot. Results fluctuate depending on the load on the server and the test environment. Measure several times if needed.
- Measurement takes place in a simulated environment (lab data). The real user data, if available, shows how your visitors actually experience the site.
- Only one page is measured, usually the home page. Other pages may be better or worse.
- The mobile measurement is stricter than the desktop measurement and, for most businesses, the more meaningful one.
Treat the result as a starting point for a conversation, not as a verdict.
