askbio.com website review

27 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.9 s.

61 files are served with short cache lifetimes, so returning visitors download them again (929 KiB).

About 217 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.6 s faster on a phone.

Your mobile performance score is 58 (desktop: 88). Pages that score under 90 lose visitors before the first paint.

6 images could be 185 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 500 ms faster on a phone.

About 78 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

9 KiB could be saved by minifying CSS.

2 third-party services load with your homepage (Cookiebot and Google Fonts), adding 246 KiB and 109 ms of main-thread time.

1 long task block the main thread while loading, the longest for 62 ms. During a long task the page ignores taps.

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

21 KiB could be saved by minifying JavaScript.

Desktop scores 88 but mobile only 58. A gap that wide usually means heavy scripts and images that hit phones hardest.

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.

Your largest element takes 8.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The first text or image appears after 5.0 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 8.0 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 8.7 s. Good is under 3.8 s.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.9 s to 1.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

2 images (96 KiB) 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.

2 images further down the page (96 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 0.44 g of CO₂e: 52.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

All page content should be contained by landmarks: 7 elements on the page fail this check, rated moderate by axe-core.

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

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

Elements with visible text labels do not have matching accessible names. (1 element).

There are 2 <h1> headlines (“Helping lead a new era of genetic medicine.” and “We are on a never-ending quest to advance genetic…”). One clear main headline is easier for people and search engines.

Your meta description is 208 characters; Google truncates after about 160, so the end of your pitch is cut.

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

The homepage links to 81 pages on askbio.com and 4 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.

/careers has no meta description, so Google writes the search snippet from whatever text it finds.

/careers took over 3 s to send its HTML from our server.

We fetched 15 pages linked from your homepage (of 32 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “elementorFrontendConfig is not defined”.

2 links from your homepage to your own site are broken, for example https://www.askbio.com/patient-advocacy/ (404).

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 Permissions-Policy header to switch off camera, microphone and location for embedded content.

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.

askbio.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.

askbio.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.

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

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 365 words of visible text.

DMARC is set to p=none, so mail pretending to be askbio.com is still delivered. Reports are on, so moving to quarantine is the next step.

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.

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