One score from every part of this review. How it works
Speed
Render-blocking requests
1.9 s6 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.9 s.
Improve image delivery
1.0 s · 443 KiB14 images could be 443 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.0 s faster on a phone.
Mobile performance score: 83
83/100Your mobile performance score is 83 (desktop: 97). Pages that score under 90 lose visitors before the first paint.
1 long task on the main thread
1 long task block the main thread while loading, the longest for 58 ms. During a long task the page ignores taps.
3 third-party services on the page
3 third-party services load with your homepage (Unpkg, Google Fonts and openstreetmap.org), adding 214 KiB and 31 ms of main-thread time.
Use efficient cache lifetimes
43 KiB4 files are served with short cache lifetimes, so returning visitors download them again (43 KiB).
Reduce unused JavaScript
24 KiBAbout 24 KiB of JavaScript is downloaded but never used on this page.
Reduce unused CSS
11 KiBAbout 11 KiB of CSS is downloaded but never applied on this page.
Minify CSS
6 KiB6 KiB could be saved by minifying CSS.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.
Minify JavaScript
2 KiB2 KiB could be saved by minifying JavaScript.

Main-thread work: 0.7 s
A phone's processor spends 0.7 s on main-thread work while loading, 83 ms of it running JavaScript. That is comfortably low.
Server response: 4 ms
4 msYour server sent the HTML in 4 ms, well inside Google's 600 ms guideline.
Core Web Vitals
Largest Contentful Paint: 3.9 s
3.9 sYour largest element takes 3.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.
First Contentful Paint: 2.7 s
2.7 sThe first text or image appears after 2.7 s on a phone. Good is under 1.8 s.
Speed Index: 3.6 s
3.6 sVisually, the page fills in at 3.6 s (Speed Index). Good is under 3.4 s.
Time to Interactive: 3.9 s
3.9 sThe page becomes fully interactive after 3.9 s. Good is under 3.8 s.
1 image without width and height
1 image have no width and height attributes, so the layout jumps as each one loads.
Tap response (INP) held steady for real visitors
-3%Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 99 ms to 98 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).
Largest content (LCP) held steady for real visitors
-8%Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 4.8 s to 3.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).
Not enough real-visitor data yet
Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Cumulative Layout Shift: 0.004
0.004The layout barely moves while loading (CLS 0.004, good is under 0.1).
Total Blocking Time: 0 ms
0 msScripts block the page for only 0 ms while loading. Good is under 200 ms.
Images and page weight
4 images in older formats
4 images (139 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.
3 images below the first screen load straight away
3 images further down the page (102 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.
About 0.3 g of CO₂ per visit
0.33 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.33 g of CO₂e: 39.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
2 checks passed
Page weight: 1.2 MB in 38 requests
1.2 MBYour homepage downloads 1.2 MB in 38 requests on a phone: images 995 KiB (19), scripts 59 KiB (5) and fonts 57 KiB (8). That is a lean page.
Images are sized for phones
No image is downloaded at more than three times the size it is drawn on a phone.
Accessibility
20 text elements with low contrast
20 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
ARIA commands must have an accessible name (4 elements)
ARIA commands must have an accessible name: 4 elements on the page fail this check, rated serious by axe-core.
Scrollable region must have keyboard access (1 element)
Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.
Headings skip levels
Headings skip levels (h2 → h4, h2 → h4 and h2 → h4), which makes the page harder to scan with a screen reader.
2 checks passed
Every image has alt text
All 15 images in the HTML carry an alt attribute.
42 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 46 WCAG 2.2 A/AA and best-practice rules on the phone render: 42 passed and 4 failed. 2 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
Title is short (29 characters)
Your title is only 29 characters: “Zebol · Soluciones que fluyen”. Between 30 and 65 characters leaves room to say what you do and for whom.
No structured data
No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.
No canonical URL
No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.
No social preview image
No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.
No XML sitemap
No XML sitemap at https://zebol.com/sitemap.xml, so Google discovers your pages only by following links.
No robots.txt
There is no robots.txt at zebol.com/robots.txt, the first file search crawlers ask for.
Only 3 internal links
The homepage links to only 3 pages on your own site, so visitors and crawlers find few routes into the rest of it.
2 checks passed
Meta description: 123 characters
Your meta description is 123 characters: “Sistemas de bombeo, mantenimiento y soluciones de fluidos para industria, agricultura y desarrollo comercial en Costa R…”.
One H1 headline
Your main headline reads: “Soluciones que fluyen”.
AI search readiness
No Organization structured data
There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.
No llms.txt
There is no https://zebol.com/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.
2 checks passed
AI answer engines may read the site
There is no robots.txt, so nothing stops the crawlers behind ChatGPT search, Claude and Perplexity from reading the site and cite it in answers.
Text is in the HTML
Your server sends the page's text in the HTML (831 words), so crawlers that don't run JavaScript still read it.
Other pages
3 pages without a meta description
https://zebol.com/terminos-condiciones.html, https://zebol.com/politicas-garantia.html and https://zebol.com/politicas-privacidad.html have no meta description, so Google writes the search snippet from whatever text it finds.
3 internal pages checked
We fetched 3 pages linked from your homepage and read each the way a search engine does.
6 checks passed

Titles are unique
Every page we checked has its own title.
Every page has an H1

All 3 pages that loaded have a <title>.
Best practices
1 broken image
1 image failed to load on a phone, for example https://zebol.com/.
3 JavaScript errors while loading
3 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.
2 checks passed
Tap targets are thumb-sized
6 of 6 tappable elements near the top are at least 24 px.
Mobile viewport set
The page declares a mobile viewport.
Content and conversion
No call to action on the first screen
On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.
No calls to action
We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.
Local business without LocalBusiness data
Your homepage shows a map but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.
Thin social proof
Social proof on the homepage: 2 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.
No analytics detected
No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.
No opening hours
The homepage shows no opening hours. If customers visit or call, show when.
No form on the homepage
There is no form on the homepage, so every lead has to click through to another page first.
No risk reducer
No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.
About 1,071 words of copy
The homepage carries about 1,071 words of visible text.
2 checks passed
Direct contact links
Visitors can reach you directly: 6 phone links and 4 email links.
Phone number on the homepage
Your phone number is on the homepage as a tap-to-call link.
Privacy and tracking
No consent tool detected
No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.
6 other companies contacted
Loading the homepage contacts 6 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
1 checks passed
No known trackers before consent
No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).
Security, domain, email and software versions
The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at zebol.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
