mccann.ca website review

3 third-party services load with your homepage (Google Tag Manager, prismic.io and Google Analytics), adding 11.1 MB and 211 ms of main-thread time.

prismic.io costs a phone 10 ms of main-thread work and 10.8 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.

Your mobile performance score is 70. Pages that score under 90 lose visitors before the first paint.

About 174 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 750 ms faster on a phone.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

3 long tasks block the main thread while loading, the longest for 146 ms. During a long task the page ignores taps.

5 images could be 96 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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.

Your largest element takes 10.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “McCann logo”.

The page becomes fully interactive after 10.9 s. Good is under 3.8 s.

Visually, the page fills in at 4.9 s (Speed Index). Good is under 3.4 s.

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

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 11.9 MB in 74 requests on a phone: media 10.0 MB (8), images 819 KiB (20) and fonts 572 KiB (4). Under 2 MB keeps phones on slow connections fast.

2 images further down the page (50 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 3.36 g of CO₂e: 403.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

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

There is no robots.txt at mccann.ca/robots.txt, the first file search crawlers ask for.

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

The homepage links to 11 pages on mccann.ca and 5 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 https://mccann.ca/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 3 pages linked from your homepage and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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.

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

The homepage shows no opening hours. If customers visit or call, show when.

There is no form on the homepage, so every lead has to click through to another page first.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 900 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics and Google Tag Manager (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 2 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 6 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
