prenatalscreening.com website review

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

About 177 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.1 s faster on a phone.

About 148 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 42. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

2 images could be 454 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 950 ms faster on a phone.

57 KiB could be saved by minifying CSS.

41 KiB could be saved by minifying JavaScript.

3 third-party services load with your homepage (Google Tag Manager, Optanon and Google Fonts), adding 367 KiB and 262 ms of main-thread time.

4 files are served with short cache lifetimes, so returning visitors download them again (58 KiB).

6 long tasks block the main thread while loading, the longest for 109 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

Polyfills for old browsers add 9 KiB JavaScript that modern phones do not need.

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.

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 image.

The layout shifts by 0.615 while loading, so content jumps under the reader's thumb. Good is under 0.1.

The page becomes fully interactive after 9.1 s. Good is under 3.8 s.

Visually, the page fills in at 5.9 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.8 s on a phone. Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 92 ms to 89 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 2.4 s to 2.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

1 image (150 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.

2 images further down the page (208 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.41 g of CO₂e: 48.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Some list items are not inside a list.

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

Headings skip levels (h3 → h5), which makes the page harder to scan with a screen reader.

Structured data found (BreadcrumbList, WebPage and WebSite) but with 1 problem, for example “BreadcrumbList: itemListElement is an empty list”.

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

1 link has no real href, so search engines can't follow it.

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

The homepage links to 27 pages on prenatalscreening.com and 13 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.

There is no https://prenatalscreening.com/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.

https://prenatalscreening.com/types-of-prenatal-screening-tests and https://prenatalscreening.com/prenatal-screening-benefits all use the title “Types of Prenatal Screening Test | Know more sooner”. Search engines can't tell which page to show for a search, so each competes with the others.

https://prenatalscreening.com/providers, https://prenatalscreening.com/es/home and https://prenatalscreening.com/prenatal-path have no meta description, so Google writes the search snippet from whatever text it finds.

https://prenatalscreening.com/types-of-prenatal-screening-tests and https://prenatalscreening.com/prenatal-screening-benefits use the same meta description. A description written for each page earns more clicks.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://prenatalscreening.com/prenatal-screening-benefits, whose canonical is https://prenatalscreening.com/types-of-prenatal-screening-tests. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 10 pages linked from your homepage and read each the way a search engine does.

3 of 10 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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

There is no form on the homepage, so every lead has to click through to another page first.

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 372 words of visible text.

Before a visitor clicks anything, the page loads Google Tag Manager (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 3 cookies (measured from a US location before any click).

Loading the homepage contacts 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
