iponweb.com website review

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.2 s.

Your mobile performance score is 44 (desktop: 60). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.1 s on main-thread work while loading, 2.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, reddit and Facebook and others), adding 1.5 MB and 1.8 s of main-thread time.

About 166 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 750 ms faster on a phone.

Google Tag Manager costs a phone 631 ms of main-thread work and 709 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.

reddit costs a phone 612 ms of main-thread work and 26 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.

About 573 KiB of JavaScript is downloaded but never used on this page.

14 files are served with short cache lifetimes, so returning visitors download them again (436 KiB).

18 long tasks block the main thread while loading, the longest for 282 ms. During a long task the page ignores taps.

66 KiB could be saved by minifying JavaScript.

Polyfills for old browsers add 59 KiB JavaScript that modern phones do not need.

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.

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 26.7 s. Good is under 3.8 s.

Your largest element takes 7.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Criteo Enters Into Exclusive Negotiations to Acquire IPONWE…”.

Scripts block taps and scrolling for 1.1 s in total while the page loads. Good is under 200 ms.

Real visitors wait 302 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 214 ms to 298 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.1 s (75th percentile). Good is under 1.8 s.

The first text or image appears after 2.9 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 5.4 s (Speed Index). Good is under 3.4 s.

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

Your homepage downloads 3.4 MB in 150 requests on a phone: scripts 1.9 MB (53), fonts 1.2 MB (14) and stylesheets 173 KiB (9). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.96 g of CO₂e: 114.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Some list items are not inside a list.

ARIA input fields must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

Interactive controls must not be nested: 1 element on the page fails this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 53 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.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

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

Elements with role="dialog" or role="alertdialog" do not have accessible names. (1 element).

ARIA role should be appropriate for the element: 7 elements on the page fail this check, rated minor by axe-core.

Your title is 111 characters, so Google will cut it off around 60: “Criteo Enters Into Exclusive Negotiations to Acquire IPONWEB, a Market-Leading AdTech Pla…”.

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

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

The homepage links to 143 pages on iponweb.com and 35 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

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.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /news/press-releases/2026/10/criteo-ssp-recognized-by-frost-sullivan-for-commerce-media-innovation/%20, whose canonical is /news/press-releases/2026/10/criteo-ssp-recognized-by-frost-sullivan-for-commerce-media-innovation. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/talk-to-an-expert has no <h1> headline, so visitors and search engines get no clear main topic.

/talk-to-an-expert has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 15 pages linked from your homepage (of 79 found) and read each the way a search engine does.

4 of 5 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

HSTS is set, but max-age is 0 days; one year is the recommended minimum.

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

3 links go through two or more redirects, for example http://www.linkedin.com/shareArticle?mini=true&url=https%3A%2F%2Fwww.criteo.com%2Fnews%2Fpress-releases%2F2021%2F12%2Fcriteo-enters-into-exclusive-negotiations-to-acquire-iponweb/&title=Criteo%20Enters%20Into%20Exclusive%20Negotiations%20to%20Acquire%20IPONWEB%2C%20a%20Market-Leading%20AdTech%20Platform%20Company&source=https%3a%2f%2fwww.criteo.com/.

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.

criteo.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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 2,594 words of visible text.

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 Amplitude, Google Ads, Google Analytics, Google Tag Manager and LinkedIn Insight and 6 mores (measured from a US location before any click). A consent tool (Usercentrics) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 21 cookies (measured from a US location before any click).

Loading the homepage contacts 41 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
