iabtechlab.com website review

44 files block the first paint until they finish downloading. Deferring or inlining them could save about 8.1 s.

About 600 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 3.5 s faster on a phone.

About 1.0 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.4 s faster on a phone.

Your mobile performance score is 49 (desktop: 50). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

37 images could be 2.9 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 250 ms faster on a phone.

120 KiB could be saved by minifying JavaScript.

73 KiB could be saved by minifying CSS.

Polyfills for old browsers add 38 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 400 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 350 ms).

A phone's processor spends 2.1 s on main-thread work while loading, 800 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, convertbox.com and Civic and others), adding 818 KiB and 406 ms of main-thread time.

4 files are served with short cache lifetimes, so returning visitors download them again (204 KiB).

The HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.

5 long tasks block the main thread while loading, the longest for 113 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.

Real visitors wait 5.0 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 4.3 s (75th percentile). Good is under 1.8 s.

The first text or image appears after 9.1 s on a phone. Good is under 1.8 s.

Your largest element takes 14.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “AAMP 3.0 with OpenProposal”.

The page becomes fully interactive after 33.2 s. Good is under 3.8 s.

Visually, the page fills in at 10.6 s (Speed Index). Good is under 3.4 s.

Real visitors wait 214 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-10, real Chrome visitors' tap response (inp) went from 141 ms to 202 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors wait 1.6 s for your server to start answering (75th percentile). Good is under 800 ms.

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

The layout shifts by 0.133 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Over the last 25 four-week periods to 2026-10-10, real Chrome visitors' largest content (lcp) went from 4.1 s to 4.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 8.5 MB in 158 requests on a phone: images 5.5 MB (64), scripts 2.0 MB (51) and stylesheets 683 KiB (32). Under 2 MB keeps phones on slow connections fast.

International-Summit-2026-PPT.png weighs 1.3 MB. On a phone connection a single image that size takes seconds.

15 images are downloaded at several times the size a phone draws them, for example International-Summit-2026-PPT.png at 1,920 px wide, shown at 390 px. Resized copies would save about 1.7 MB.

33 images (5.0 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.

19 images further down the page (1.4 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

AAMP-3.0-and-OpenProposal-768x402.png is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 2.42 g of CO₂e: 290.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

11 tap targets are too small or too close together to hit reliably with a finger.

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

All page content should be contained by landmarks: 12 elements on the page fail this check, rated moderate by axe-core.

ARIA role should be appropriate for the element: 12 elements on the page fail this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (12 elements).

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

The homepage links to 99 pages on iabtechlab.com and 4 external pages.

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.

/standards is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

/membership, /board-membership, /corporate-membership, /standards, /standards/supply-chain-foundations and /standards/agentic-advertising-and-ai and 4 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 55 found) and read each the way a search engine does.

17 of 39 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The server only offers HTTP/1.1, so browsers open several connections and load files more slowly. Most hosts and CDNs turn on HTTP/2 with a setting.

1 link go through two or more redirects, for example https://iabtechlab.com/standards.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

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

iabtechlab.com 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.

iabtechlab.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.

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

Social proof on the homepage: 2 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

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 272 words of visible text.

DMARC is set to p=none, so mail pretending to be iabtechlab.com is still delivered. Add a report address, check the reports, then move to quarantine.

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 Tag Manager (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.

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