exa.ai website review

About 325 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 760 ms faster on a phone.

Your mobile performance score is 59. Pages that score under 90 lose visitors before the first paint.

32 files are served with short cache lifetimes, so returning visitors download them again (361 KiB).

A phone's processor spends 3.7 s on main-thread work while loading, 2.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

Google Tag Manager costs a phone 95 ms of main-thread work and 354 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.

8 third-party services load with your homepage (Google Tag Manager, Hubspot and vector.co and others), adding 667 KiB and 255 ms of main-thread time.

Polyfills for old browsers add 72 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

About 26 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

11 long tasks block the main thread while loading, the longest for 168 ms. During a long task the page ignores taps.

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

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.

The page becomes fully interactive after 15.0 s. Good is under 3.8 s.

The first text or image appears after 4.2 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 7.0 s (Speed Index). Good is under 3.4 s.

Your largest element takes 4.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “The world's data for AI agents”. Most of its time is element render delay (2.4 s).

Real visitors wait 258 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Scripts block taps and scrolling for 465 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 221 ms to 212 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.4 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.0 MB in 163 requests on a phone: scripts 1.4 MB (56), fonts 408 KiB (10) and images 153 KiB (34). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.58 g of CO₂e: 69.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Elements must only use permitted ARIA attributes: 2 elements on the page fail this check, rated serious by axe-core.

All page content should be contained by landmarks: 58 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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

Elements with visible text labels do not have matching accessible names. (2 elements).

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

The homepage links to 81 pages on exa.ai and 19 external pages.

https://exa.ai/products/monitors is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

We fetched 15 pages linked from your homepage (of 47 found) and read each the way a search engine does.

9 of 27 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 403 ()”.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 620 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, HubSpot and LinkedIn Insight and 2 mores (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 28 cookies, 7 of them by other companies (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 34 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
