Content is not blocked for zoom/scale

The `[user-scalable="no"]` parameter is not present in the `<meta name="viewport">` element and the `[maximum-scale]` parameter is not less than 2.Source: Lighthouse - Learn more

Content is sized correctly for the viewport

If the width of your app's content doesn't match the width of the viewport, your app might not be optimized for mobile screens. Source: Lighthouse - Learn more

Uses legible font sizes

Font sizes less than 12px are too small to be legible and require mobile visitors to “pinch to zoom” in order to read. Strive to have >60% of page text ≥12px. Source: Lighthouse - Learn more

Color Contrast is satisfactory

Low-contrast text is difficult or impossible for many users to read. Background and foreground colors should have enough contrast ratio to guarantee readability. Source: Lighthouse - Learn more

Autocomplete is used to suggest popular searches (but can be ignored)

Fails if no autocomplete or if the user is not allowed to ignore the autocomplete.

Filtering is available and prominent on search results or category listing pages

Fails if filtering is appropriate but not provided or if sorting is prioritized over filtering in the visual hierarchy.

The product details follow a set pattern making it easier to compare, e.g. bullet points with tech specs

Fails if different product description information formatting from one page to another.

It is possible to check in-store product availability

Fails if in-store product availability is not provided.

All product images are zoomable, without blur

Fails if product images are blurry at full zoom.

Carousels are generally avoided (but they are acceptable if they are well implemented)

Fails if any of the following are seen: carousels auto-rotate, text is not legible, swipe is not supported, next images do not load within 1 second of swipe.

There is a choice to convert without creating an account, i.e. Guest checkout

Fails if most helpful keyboard not provided, i.e. input types text, tel, email, password, capitalization when appropiate, etc.

The website supports autofill for all form fields and the fields are tagged for the appropriate information from autofill

Fails if fields are not tagged for efficient browser-based autofill, making users enter data that is already known either by the website or the OS. Not filling a standard field or filling fields with the wrong content, i.e. puts house number and street name into the same field when there are separate fields for each.

All mistakes made in forms are clearly highlighted in real time, and instructions for correct completion are provided in real time

Fails if mistakes and guidance for correct completion are not highlighted in real time and/or error messages are ambiguous or unfriendly.
