integralads.com website review

33 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.0 s.

About 234 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.1 s faster on a phone.

Your mobile performance score is 31 (desktop: 44). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 8.2 s on main-thread work while loading, 1.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

15 long tasks block the main thread while loading, the longest for 1.9 s. During a long task the page ignores taps.

8 third-party services load with your homepage (Google Tag Manager, Marketo and Optanon and others), adding 1.2 MB and 1.1 s of main-thread time.

About 757 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

14 files are served with short cache lifetimes, so returning visitors download them again (233 KiB).

Google Tag Manager costs a phone 876 ms of main-thread work and 850 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.

3 images could be 447 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

The page has 1,780 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Polyfills for old browsers add 41 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

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

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 0.32 (75th percentile). Good is under 0.1.

Your largest element takes 9.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “INTEGRAL AD SCIENCE THE MOST ACTIONABLE DATA TO DRIVE SUPER…”.

The page becomes fully interactive after 21.3 s. Good is under 3.8 s.

Visually, the page fills in at 12.4 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.5 s on a phone. Good is under 1.8 s.

The layout shifts by 0.312 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Real visitors wait 3.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 235 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 80 ms to 112 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.5 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 505 ms in total while the page loads. Good is under 200 ms.

7 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.6 s to 1.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.5 MB in 166 requests on a phone: scripts 1.7 MB (55), images 1.5 MB (45) and fonts 922 KiB (6). Under 2 MB keeps phones on slow connections fast.

1 image (95 KiB) is 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.

1 image further down the page (36 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.27 g of CO₂e: 152.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

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

1 tap target is too small or too close together to hit reliably with a finger.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

7 visible links have no text or label, so screen readers cannot say where they go.

Headings skip levels (h1 → h3, h2 → h4 and h4 → h6), which makes the page harder to scan with a screen reader.

15 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

Your hreflang tags are invalid, so Google may show the wrong language version.

The homepage links to 158 pages on integralads.com and 15 external pages.

We fetched 15 pages linked from your homepage (of 51 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=283025849&tm=gtm002&Ver=2&mid=53e7dcef-4188-48e3-b3d5-fc75da56ed71&bo=1&sid=babb8810d24111f18a4c63d461ca9283&vid=babbbc90d24111f195fe63c65b0868c7&vids=1&msclkid=N&pi=9.

5 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 ()”.

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

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 873 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Hotjar and LinkedIn Insight and 2 mores (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 25 cookies (measured from a US location before any click).

Loading the homepage contacts 31 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
