rachio.com website review

10 images could be 561 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.5 s faster on a phone.

About 312 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.4 s faster on a phone.

Your mobile performance score is 55. Pages that score under 90 lose visitors before the first paint.

8 files are served with short cache lifetimes, so returning visitors download them again (86 KiB).

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 650 ms.

8 third-party services load with your homepage (Google Tag Manager, Optanon and Yotpo and others), adding 1.2 MB and 316 ms of main-thread time.

Polyfills for old browsers add 22 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 350 ms faster on a phone.

sanity.io costs a phone 0 ms of main-thread work and 705 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.

5 long tasks block the main thread while loading, the longest for 171 ms. During a long task the page ignores taps.

About 47 KiB of CSS is downloaded but never applied on this page.

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.

3 KiB could be saved by minifying JavaScript.

Your largest element takes 12.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “It Just Works Watering”.

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

The first text or image appears after 4.1 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 6.9 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 274 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 87 ms to 102 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.0 s to 1.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

By the Sustainable Web Design model, a visit to your homepage emits about 0.56 g of CO₂e: 67.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

Elements with visible text labels do not have matching accessible names. (8 elements).

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

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

The homepage links to 52 pages on rachio.com and 19 external pages.

https://rachio.com/products/smart-lighting-controller and https://rachio.com/products/bundles/rachio-smart-lighting-controller-and-fixtures all use the title “Rachio Smart Lighting Controller | Rachio”. Search engines can't tell which page to show for a search, so each competes with the others.

https://rachio.com/products/rachio-3 and https://rachio.com/products/rachio-3-refurbished use the same meta description. A description written for each page earns more clicks.

https://rachio.com/products/collections/watering, https://rachio.com/products and https://rachio.com/products/collections/bulk-bundle have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 22 found) and read each the way a search engine does.

Large scripts ship without source maps.

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.

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 973 words of visible text.

Before a visitor clicks anything, the page loads Amazon Ads, Google Ads and Google Tag Manager (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 7 cookies (measured from a US location before any click).

Loading the homepage contacts 12 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
