bitbase.es website review

90 files are served with short cache lifetimes, so returning visitors download them again (3.7 MB).

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

Your mobile performance score is 27 (desktop: 54). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 5.5 s on main-thread work while loading, 3.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and ZenDesk and others), adding 2.5 MB and 1.8 s of main-thread time.

About 1.1 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 600 ms faster on a phone.

13 images could be 1.4 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Google CDN costs a phone 686 ms of main-thread work and 1.1 MB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Google Tag Manager costs a phone 379 ms of main-thread work and 364 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

ZenDesk costs a phone 324 ms of main-thread work and 413 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

The page has 2,508 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 14 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 270 ms faster on a phone.

20 long tasks block the main thread while loading, the longest for 215 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 12 KiB JavaScript that modern phones do not need.

Desktop scores 54 but mobile only 27. A gap that wide usually means heavy scripts and images that hit phones hardest.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

For real visitors the layout shifts by 0.55 (75th percentile). Good is under 0.1.

The page becomes fully interactive after 21.8 s. Good is under 3.8 s.

The layout shifts by 1 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Scripts block taps and scrolling for 1.2 s in total while the page loads. Good is under 200 ms.

Your largest element takes 4.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Usamos cookies y otras técnicas de rastreo para mejorar tu …”.

The first text or image appears after 3.1 s on a phone. Good is under 1.8 s.

Real visitors wait 2.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Visually, the page fills in at 5.0 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 2.5 s to 2.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.3 MB in 140 requests on a phone: images 3.1 MB (66), scripts 2.5 MB (38) and other files 473 KiB (21). Under 2 MB keeps phones on slow connections fast.

Contacto.21872e54.svg weighs 1.3 MB. On a phone connection a single image that size takes seconds.

10 images are downloaded at several times the size a phone draws them, for example bitbase_exchange_fisico_3785d41abf.jpg at 2,400 px wide, shown at 351 px. Resized copies would save about 1.2 MB.

11 images (1.6 MB) 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.

13 images further down the page (1.2 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.78 g of CO₂e: 213.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Images must have alternative text: 41 elements on the page fail this check, rated critical by axe-core.

1 button has no accessible name, so screen readers announce just “button”.

26 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

Form elements should have a visible label: 2 elements on the page fail this check, rated serious by axe-core.

1 frame has no title, so screen-reader users cannot tell what it contains.

1 link inside paragraphs relies on colour alone to stand out.

All page content should be contained by landmarks: 55 elements on the page fail this check, rated moderate by axe-core.

2 form fields have no label, so screen readers announce an empty box and autofill guesses.

There is no <h1>, so neither visitors nor Google get a clear main headline.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

Your meta description is 187 characters; Google truncates after about 160, so the end of your pitch is cut.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

4 links have no real href, so search engines can't follow them.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

A phone browser shows 903 words, but the HTML your server sends has only 0. GPTBot, ClaudeBot and PerplexityBot read that HTML without running JavaScript, so they see an almost empty page. Server-side rendering or pre-rendering fixes it.

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.

There is no /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.

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

bitbase.es has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

There is no form on the homepage, so every lead has to click through to another page first.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 903 words of visible text.

DMARC is set to p=none, so mail pretending to be bitbase.es is still delivered. Reports are on, so moving to quarantine is the next step.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Meta Pixel (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 7 cookies (measured from a US location before any click).

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.

Loading the homepage contacts 19 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
