Performance

Insights

Remove large, duplicate JavaScript modules from bundles to reduce unnecessary bytes consumed by network activity.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Polyfills and transforms enable older browsers to use new JavaScript features. However, many aren't necessary for modern browsers. Consider modifying your JavaScript build process to not transpile Baseline features, unless you know you must support older browsers. Learn why most sites can deploy ES6+ code without transpiling

Why this matters

Performance issues directly impact user engagement and conversion rates.

3rd party code can significantly impact load performance. Reduce and defer loading of 3rd party code to prioritize your page's content.

Why this matters

Performance issues directly impact user engagement and conversion rates.

A forced reflow occurs when JavaScript queries geometric properties (such as offsetWidth) after styles have been invalidated by a change to the DOM state. This can result in poor performance. Learn more about forced reflows and possible mitigations.

Avoid chaining critical requests by reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load.

Why this matters

Performance issues directly impact user engagement and conversion rates.

description: [preconnect](https://developer.chrome.com/docs/lighthouse/performance/uses-rel-preconnect/) hints help the browser establish a connection earlier in the page load, saving time when the first request for that origin is made. The following are the origins that the page preconnected to.

title: Preconnected origins

description: Add [preconnect](https://developer.chrome.com/docs/lighthouse/performance/uses-rel-preconnect/) hints to your most important origins, but try to use no more than 4.

title: Preconnect candidates

value: No additional origins are good candidates for preconnecting

Requests are blocking the page's initial render, which may delay LCP. Deferring or inlining can move these network requests out of the critical path.

Accessibility

These checks highlight opportunities to improve the accessibility of your web app. Automatic detection can only detect a subset of issues and does not guarantee the accessibility of your web app, so manual testing is also encouraged.

ARIA

When an element doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers. Learn how to make command elements more accessible.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
body.todoistTheme > div.appContainer > astro-island > div._overlay_1d1qk_6 `body.todoistTheme > div.appContainer > astro-island > div._overlay_1d1qk_6`

These are opportunities to improve the usage of ARIA in your application which may enhance the experience for users of assistive technology, like a screen reader.

Contrast

Low-contrast text is difficult or impossible for many users to read. Learn how to provide sufficient color contrast.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
Start for free `ul._navbarItemGroup_ue8ah_1 > li._navbarItem_53i31_1 > a._text_qx30j_1 > span._textWrapper_1yend_73`
Clear your mind `div > div.text-lock-up > div.text-container > p._text_qx30j_1`
Plan with confidence `div > div.text-lock-up > div.text-container > p._text_qx30j_1`

These are opportunities to improve the legibility of your content.

Tables and lists

Screen readers require list items (`<li>`) to be contained within a parent `<ul>`, `<ol>` or `<menu>` to be announced properly. Learn more about proper list structure.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
Work `div._hidden_snh3y_1 > div.mbe-24 > ul > li`
Personal `div._hidden_snh3y_1 > div.mbe-24 > ul > li`
Education `div._hidden_snh3y_1 > div.mbe-24 > ul > li`
Management `div._hidden_snh3y_1 > div.mbe-24 > ul > li`
Marketing & Sales `div._hidden_snh3y_1 > div.mbe-24 > ul > li`
Customer Support `div._hidden_snh3y_1 > div.mbe-24 > ul > li`

Best Practices

User Experience

Image display dimensions should match natural aspect ratio. Learn more about image aspect ratio.

Why this matters

Performance issues directly impact user engagement and conversion rates.

	URL	Aspect Ratio (Displayed)	Aspect Ratio (Actual)
div.hero > div.illustration > div.image-container > img.background-image `div.hero > div.illustration > div.image-container > img.background-image`	www.todoist.com/_astro/background.BbIjsenq_13uyaQ.webp	728 x 590 (1.23)	590 x 332 (1.78)

Image natural dimensions should be proportional to the display size and the pixel ratio to maximize image clarity. Learn how to provide responsive images.
