allergyweb.com website review

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

Your mobile performance score is 40 (desktop: 88). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

About 85 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 900 ms faster on a phone.

8 third-party services load with your homepage (Google Tag Manager, Facebook and Google CDN and others), adding 1.1 MB and 791 ms of main-thread time.

8 files are served with short cache lifetimes, so returning visitors download them again (239 KiB).

About 590 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

Google Tag Manager costs a phone 415 ms of main-thread work and 535 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 75 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 350 ms faster on a phone.

Google CDN costs a phone 106 ms of main-thread work and 347 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.

1 image could be 11 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 200 ms faster on a phone.

20 KiB could be saved by minifying JavaScript.

9 long tasks block the main thread while loading, the longest for 168 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).

Desktop scores 88 but mobile only 40. 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.

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 7.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “At Asthma & Allergy Associates of Florida, we help patients…”.

The page becomes fully interactive after 15.7 s. Good is under 3.8 s.

The first text or image appears after 4.2 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 6.7 s (Speed Index). Good is under 3.4 s.

The layout shifts by 0.262 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Real visitors see the first content after 1.9 s (75th percentile). Good is under 1.8 s.

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

Scripts block taps and scrolling for 342 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 97 ms to 103 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.2 MB in 141 requests on a phone: scripts 1.4 MB (48), images 495 KiB (19) and stylesheets 196 KiB (51). Under 2 MB keeps phones on slow connections fast.

3 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.

5 images further down the page (164 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 0.62 g of CO₂e: 75.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must be contained by particular parents: 2 elements on the page fail this check, rated critical by axe-core.

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

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

Some lists contain elements other than list items, which screen readers announce wrongly.

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.

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

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

5 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 77 pages on allergyweb.com and 3 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 /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.

We fetched 15 pages linked from your homepage (of 40 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://jelly.mdhv.io/v1/star.gif?pid=lbFCNK34mVANX0Ly8jAuCOyLLihz&src=mh&evt=hi.

12 of 26 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

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.

allergyweb.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.

allergyweb.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: 2 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

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 571 words of visible text.

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, Meta Pixel and Microsoft Clarity (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.

Opening the homepage sets 23 cookies (measured from a US location before any click).

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