adconversion.com website review

About 762 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.5 s faster on a phone.

28 files are served with short cache lifetimes, so returning visitors download them again (526 KiB).

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.9 s.

betterstack.net costs a phone 1.8 s of main-thread work and 112 KiB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

A phone's processor spends 10.1 s on main-thread work while loading, 4.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 29. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

The page has 9,771 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (betterstack.net, Google Tag Manager and website-files.com and others), adding 1.9 MB and 3.3 s of main-thread time.

Google Tag Manager costs a phone 911 ms of main-thread work and 872 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 117 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 520 ms faster on a phone.

20 long tasks block the main thread while loading, the longest for 612 ms. During a long task the page ignores taps.

website-files.com costs a phone 228 ms of main-thread work and 422 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.

Polyfills for old browsers add 56 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 100 ms faster on a phone.

2 images could be 21 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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.

Your largest element takes 18.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “We use cookies to personalise content and ads, to provide s…”.

The page becomes fully interactive after 20.7 s. Good is under 3.8 s.

The first text or image appears after 5.9 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 10.1 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 1.8 s in total while the page loads. Good is under 200 ms.

Real visitors wait 3.2 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 154 ms to 206 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.2 s (75th percentile). Good is under 1.8 s.

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

Your homepage downloads 2.6 MB in 121 requests on a phone: scripts 2.2 MB (56), stylesheets 128 KiB (3) and images 87 KiB (8). Under 2 MB keeps phones on slow connections fast.

1 image further down the page (21 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 0.73 g of CO₂e: 87.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

131 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: 5 elements on the page fail this check, rated serious by axe-core.

All page content should be contained by landmarks: 75 elements on the page fail this check, rated moderate by axe-core.

Document should not have more than one banner landmark: 1 element on the page fails this check, rated moderate by axe-core.

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.

1 visible link has no text or label, so screen readers cannot say where it goes.

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

The homepage links to 109 pages on adconversion.com and 24 external pages.

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.

/expertise/creative-services is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

/agency/saas-video-ads, /agency/abm-agency, /agency/demand-generation-agency, /expertise/creative-services, /agency/saas-landing-pages and /agency/data-analytics-agency and 5 others have no meta description, so Google writes the search snippet from whatever text it finds.

/expertise/cybersecurity-saas and /expertise/hr-saas use the same meta description. A description written for each page earns more clicks.

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

The page uses 1 deprecated browser API that will stop working in future browsers (“Authorization will not be covered by the wildcard symbol (*) in CORS `Access-Control-Allow-Headers`…”).

3 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 Content-Security-Policy header, the main browser-side defence against injected scripts.

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

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.

adconversion.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.

adconversion.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.

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

The homepage carries about 2,687 words of visible text.

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

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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, Hotjar and Mixpanel and 1 more (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 30 cookies (measured from a US location before any click).

Loading the homepage contacts 47 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
