optimal-selection.com website review

Your mobile performance score is 83. Pages that score under 90 lose visitors before the first paint.

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 750 ms.

About 392 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 30 ms faster on a phone.

Google Tag Manager costs a phone 338 ms of main-thread work and 481 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.

A phone's processor spends 2.8 s on main-thread work while loading, 793 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 1,746 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Google Tag Manager, Optanon and Shopify and others), adding 901 KiB and 492 ms of main-thread time.

5 long tasks block the main thread while loading, the longest for 153 ms. During a long task the page ignores taps.

2 images could be 92 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

9 files are served with short cache lifetimes, so returning visitors download them again (85 KiB).

About 75 KiB of CSS is downloaded but never applied on this page.

14 KiB could be saved by minifying JavaScript.

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.

The page becomes fully interactive after 12.7 s. Good is under 3.8 s.

Visually, the page fills in at 7.5 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 96 ms to 120 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The first text or image appears after 2.5 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 216 ms in total while the page loads. Good is under 200 ms.

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

Your homepage downloads 2.7 MB in 217 requests on a phone: scripts 990 KiB (43), other files 986 KiB (123) and fonts 314 KiB (8). Under 2 MB keeps phones on slow connections fast.

Feature_OS_Species_Dog_Tier_Advanced_Size_Lg.webp is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

1 image (117 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 0.76 g of CO₂e: 91.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA dialog and alertdialog nodes should have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

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

There are 2 <h1> headlines (“” and “Introducing Litter Predict”). One clear main headline is easier for people and search engines.

Your meta description is 182 characters; Google truncates after about 160, so the end of your pitch is cut.

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

The homepage links to 92 pages on optimal-selection.com and 27 external pages.

https://optimal-selection.com/products/optimal-selection-canine-profile and https://optimal-selection.com/products/optimal-selection-advanced-canine all use the title “Optimal Selection Advanced - Canine”. Search engines can't tell which page to show for a search, so each competes with the others.

https://optimal-selection.com/pages/our-science, https://optimal-selection.com/pages/research and https://optimal-selection.com/blogs/news 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://optimal-selection.com/products/optimal-selection-canine-profile, whose canonical is https://optimal-selection.com/products/optimal-selection-advanced-canine. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 25 found) and read each the way a search engine does.

6 of 27 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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

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 717 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Meta Pixel (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 19 cookies (measured from a US location before any click).

Loading the homepage contacts 15 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
