Ert-notes.herokuapp.com Mobile Performance: 23/100

Quick overview:

Opportunities

These suggestions can help your page load faster. They don't directly affect the Performance score.

Eliminate render-blocking resources. Potential savings of 1,380 ms

Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. Learn more.

Reduce initial server response time. Root document took 910 ms

Keep the server response time for the main document short because all other requests depend on it. Learn more.

Properly size images. Potential savings of 101 KiB

Serve images that are appropriately-sized to save cellular data and improve load time. Learn more.

Serve images in next-gen formats. Potential savings of 55 KiB

Image formats like JPEG 2000, JPEG XR, and WebP often provide better compression than PNG or JPEG, which means faster downloads and less data consumption. Learn more.

Diagnostics

More information about the performance of your application. These numbers don't directly affect the Performance score.

Ensure text remains visible during webfont load

Leverage the font-display CSS feature to ensure text is user-visible while webfonts are loading. Learn more.

Minimize main-thread work

6.8 s

Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. Learn more

Reduce JavaScript execution time

4.5 s

Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn more.

Largest Contentful Paint element

1 element found

This is the largest contentful element painted within the viewport. Learn More

Avoid chaining critical requests

1 chain found

The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load. Learn more.

Avoid long main-thread tasks

10 long tasks found

Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay. Learn more

Keep request counts low and transfer sizes small

25 requests • 1,752 KiB

To set budgets for the quantity and size of page resources, add a budget.json file. Learn more.

Avoid large layout shifts

5 elements found

These DOM elements contribute most to the CLS of the page.

Ert-notes.herokuapp.com Mobile SEO: 80/100

Quick overview:

Content Best Practices

Format your HTML in a way that enables crawlers to better understand your app’s content.

Image elements do not have `[alt]` attributes

Informative elements should aim for short, descriptive alternate text. Decorative elements can be ignored with an empty alt attribute. Learn more.

Mobile Friendly

Make sure your pages are mobile friendly so users don’t have to pinch or zoom in order to read the content pages. Learn more.

Document doesn't use legible font sizes

40.76% legible text

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. Learn more.

Tap targets are not sized appropriately

40% appropriately sized tap targets

Interactive elements like buttons and links should be large enough (48x48px), and have enough space around them, to be easy enough to tap without overlapping onto other elements. Learn more.

Ert-notes.herokuapp.com Mobile Best Practices: 93/100

Quick overview:

Trust and Safety

Does not use HTTPS

1 insecure request found

All sites should be protected with HTTPS, even ones that don't handle sensitive data. This includes avoiding mixed content, where some resources are loaded over HTTP despite the initial request being servedover HTTPS. HTTPS prevents intruders from tampering with or passively listening in on the communications between your app and your users, and is a prerequisite for HTTP/2 and many new web platform APIs. Learn more.

General

Missing source maps for large first-party JavaScript

Source maps translate minified code to the original source code. This helps developers debug in production. In addition, Lighthouse is able to provide further insights. Consider deploying source maps to take advantage of these benefits. Learn more.

Ert-notes.herokuapp.com Mobile Progressive Web App: 61/100

Quick overview:

Installable

Does not use HTTPS

1 insecure request found

Fast and reliable

Page load is not fast enough on mobile networks

Interactive at 14.6 s

A fast page load over a cellular network ensures a good mobile user experience. Learn more. Your page loads too slowly and is not interactive within 10 seconds. Look at the opportunities and diagnostics in the "Performance" section to learn how to improve.

PWA Optimized

Manifest doesn't have a maskable icon

A maskable icon ensures that the image fills the entire shape without being letterboxed when installing the app on a device. Learn more.

Content is not 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. Learn more. The viewport size of 378px does not match the window size of 360px.

Ert-notes.herokuapp.com Mobile Accessibility: 77/100

Quick overview:

Names and labels

These are opportunities to improve the semantics of the controls in your application. This may enhance the experience for users of assistive technology, like a screen reader.

Form elements do not have associated labels

Labels ensure that form controls are announced properly by assistive technologies, like screen readers. Learn more.

Buttons do not have an accessible name

When a button doesn't have an accessible name, screen readers announce it as "button", making it unusable for users who rely on screen readers. Learn more.

Links do not have a discernible name

Link text (and alternate text for images, when used as links) that is discernible, unique, and focusable improves the navigation experience for screen reader users. Learn more.

Image elements do not have `[alt]` attributes

Informative elements should aim for short, descriptive alternate text. Decorative elements can be ignored with an empty alt attribute. Learn more.

Contrast

These are opportunities to improve the legibility of your content.

Background and foreground colors do not have a sufficient contrast ratio.

Low-contrast text is difficult or impossible for many users to read. Learn more.
