audible.com website review

About 705 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.

Your mobile performance score is 33 (desktop: 49). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.9 s on main-thread work while loading, 3.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,774 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Google Tag Manager, amazon.dev and Facebook and others), adding 6.0 MB and 2.3 s of main-thread time.

45 images could be 2.2 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

62 files are served with short cache lifetimes, so returning visitors download them again (1.4 MB).

Google Tag Manager costs a phone 880 ms of main-thread work and 892 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.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 700 ms.

amazon.dev costs a phone 601 ms of main-thread work and 284 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.

media-amazon.com costs a phone 138 ms of main-thread work and 4.2 MB 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.

53 KiB could be saved by minifying JavaScript.

20 long tasks block the main thread while loading, the longest for 496 ms. During a long task the page ignores taps.

Facebook costs a phone 258 ms of main-thread work and 197 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.

cloudfront.net costs a phone 196 ms of main-thread work and 343 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 63 KiB of CSS is downloaded but never applied on this page.

Polyfills for old browsers add 35 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.

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.

The page becomes fully interactive after 34.2 s. Good is under 3.8 s.

Your largest element takes 6.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Audible Logo”.

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

Scripts block taps and scrolling for 1.6 s in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 8.3 s (Speed Index). Good is under 3.4 s.

Real visitors wait 3.1 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.1 s (75th percentile). Good is under 1.8 s.

Real visitors wait 878 ms for your server to start answering (75th percentile). Good is under 800 ms.

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

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 146 ms to 140 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 2.5 s to 2.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.2 MB in 333 requests on a phone: images 3.8 MB (136), scripts 2.1 MB (68) and other files 80 KiB (109). Under 2 MB keeps phones on slow connections fast.

40 images (2.0 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.

14 images further down the page (676 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

1 image is downloaded at several times the size a phone draws it, for example 51HIZdnqASL._SL500_.jpg at 250 px wide, shown at 76 px. Resized copies would save about 9 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.76 g of CO₂e: 211.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

5 buttons have no accessible name, so screen readers announce just “button”.

4 elements hidden from screen readers can still receive keyboard focus.

11 images have no alt text, which hurts accessibility and image search.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

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

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

Open Graph is missing og:title and og:description, so shared links fall back to guesses.

The homepage links to 147 pages on audible.com and 3 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.

Your homepage links to /pd/The-Witch-Audiobook/B0GTN8FDBN, /pd/Bram-Stokers-Dracula-Audiobook/B0H956N76W, /pd/Threshing-Day-Wing-and-Claw-Collection-Audiobook/B0GYQHXFKG, /pd/Dungeon-Crawler-Carl-Audiobook/B08V8B2CGV, /pd/The-Calamity-Club-Audiobook/B0FTBK545H and /pd/He-Who-Fights-with-Monsters-13-A-LitRPG-Adventure-Audiobook/B0H4LKXP2C and 1 other, which answer with an error. Visitors hit a dead end and search engines drop them.

We fetched 15 pages linked from your homepage (of 71 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=4004590&Ver=2&mid=97da98df-a4ee-44a6-8759-7d898631bd86&bo=1&sid=3d1c6f20c5c711f1a7516dd85ea1c176&vid=3d1cba00c5c711f18c90dff216ce6ff8&vids=1&msclkid=N&pi=918639831&lg=.

67 of 128 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

5 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

4 errors were logged to the browser console while the page loaded, for example “Identifier 'scope' has already been declared”.

Chrome logged issues while loading the page (“Cookie”).

15 links from your homepage to your own site are broken, for example https://www.audible.com/pd/The-Witch-Audiobook/B0GTN8FDBN?ref_pageloadid=not_applicable&pf_rd_p=4cc3cdf9-96ac-4f0f-b9b3-e094fac10559&pf_rd_r=Q4HPD5MESN7ZPTC4G225&plink=ReSKYPvUnWPJruw2&pageLoadId=PW9zlqTbN5kbO6VX&creativeId=32c7d04f-9938-4d74-b8cc-98935b01cae0&ref=a_hp_c1_adblp13nbssp (503).

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.

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

No Referrer-Policy header, so full URLs can leak to the sites you link to.

X-XSS-Protection is set to “1;”; 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.

audible.com is registered until Dec 2026. Make sure auto-renew is on and the card on file is current.

audible.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.

audible.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.

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.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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

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.

The homepage carries about 784 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 Amazon Ads, Google Ads, Google Tag Manager, Meta Pixel and Microsoft Ads and 2 mores (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 42 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 30 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
