simon.com website review

69 files are served with short cache lifetimes, so returning visitors download them again (1.3 MB).

About 1.0 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.3 s faster on a phone.

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.4 s.

Google Tag Manager costs a phone 1.1 s of main-thread work and 1.3 MB 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.

Your mobile performance score is 36 (desktop: 77). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 5.0 s on main-thread work while loading, 2.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Clarity and Yottaa and others), adding 1.8 MB and 1.8 s of main-thread time.

44 images could be 879 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

Polyfills for old browsers add 75 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 500 ms faster on a phone.

83 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 450 ms faster on a phone.

About 71 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 400 ms faster on a phone.

65 KiB could be saved by minifying JavaScript.

19 long tasks block the main thread while loading, the longest for 292 ms. During a long task the page ignores taps.

The page has 2,099 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

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

Desktop scores 77 but mobile only 36. 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 23.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “it's a simon thing - campaign launch hero - simon.com”.

The page becomes fully interactive after 29.8 s. Good is under 3.8 s.

The first text or image appears after 7.2 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 12.1 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 703 ms in total while the page loads. Good is under 200 ms.

For real visitors the layout shifts by 0.11 (75th percentile). Good is under 0.1.

80 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 157 ms to 169 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 1.6 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 17.6 MB in 233 requests on a phone: media 13.0 MB (2), scripts 2.5 MB (49) and images 1.5 MB (111). Under 2 MB keeps phones on slow connections fast.

10 images further down the page (304 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

1 image (38 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.

By the Sustainable Web Design model, a visit to your homepage emits about 4.99 g of CO₂e: 598.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Some list items are not inside a list.

<dl> elements must only directly contain properly-ordered <dt> and <dd> groups, <script>, <template> or <div> elements: 6 elements on the page fail this check, rated serious by axe-core.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

Links must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

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: 2 elements on the page fail this check, rated moderate by axe-core.

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

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

ARIA role should be appropriate for the element: 15 elements on the page fail this check, rated minor by axe-core.

Alternative text of images should not be repeated as text: 12 elements on the page fail this check, rated minor by axe-core.

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

Headings skip levels (h2 → h5, h2 → h4 and h2 → h4), which makes the page harder to scan with a screen reader.

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

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

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

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 45 pages on simon.com and 156 external pages.

Your robots.txt shuts out Perplexity (PerplexityBot) and Perplexity (Perplexity-User). These fetch pages to answer people's questions and cite the source, so your site can't be quoted or linked in those answers.

robots.txt blocks GPTBot, ClaudeBot, Google-Extended and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers.

https://www.simon.com/simon-said has no meta description, so Google writes the search snippet from whatever text it finds.

https://www.simon.com/travel and https://www.simon.com/simon-said have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 30 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://b.videoamp.com/d2/3f9c351f-8ba4-4f13-964f-e2ba0b1dca82/8695/impression?bwb=35&vpxid=8695&dnt=false&cevt=SITE_VISIT.

The page uses 1 deprecated browser API that will stop working in future browsers (“Synchronous `XMLHttpRequest` on the main thread is deprecated because of its detrimental effects to…”).

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

4 errors were logged to the browser console while the page loaded, for example “Loading the image 'https://b.videoamp.com/d2/3f9c351f-8ba4-4f13-964f-e2ba0b1dca82/8695/impression?bwb=35&vpxid=8695&dnt…”.

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

Social proof on the homepage: 2 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

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 813 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and Microsoft Clarity and 1 more (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 23 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.
