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

Brand logo linked to homepage

Fails if doesn't have a logo or clicking it doesn't lead you to homepage.

No ending trailing paths

Fails if doesn't provide at least one of the following: main navigation options on footers, fixed or 'smart' headers/burger-icon, Back to top or close buttons.

Active section is highlighted in navigation menus

Fails if current section or page is not visually highlighted in navigation menus, except for internal section pages where it's accepted not to highlight the parent section.

Listing/overview pages with many items implements deferred loading techniques

Fails if the website doesn't provide at least one of the following: lazy-loading, load more buttons, paginator. Doesn't provide a clear reference about the total amount of items in a portfolio or blog page.

Prevent layout shiftings when loading media. Set width and height attributes on both <img> and <video> tags

Fails if transitioning from placeholders to final images changes the rendered size of the element as media loads. Not using a solid color placeholder occupying the same dimensions as the target image, or techniques such as LQIP or SQIP that hint at the content of a media item before it loads. These changes can be disorienting for users and trigger expensive DOM layout operations that consume system resources and contribute to jank.

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.

Make it easy to contact you

Fails if the website does not provide all of the following: easy to find contact options, tap to call, mailto on emails, addresses do not link to gMaps, except being embedded.

The most appropriate keyboard for the input type is provided first

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.
