The most reliable way to check motion and interactions on any website is to review each section in four passes: trigger, movement, timing, and result. Capture what happens before the interaction, during it, and after it finishes. Then record whether the motion helps the visitor understand what changed.

Use a repeatable interaction checklist

Start with the page in its default state and work from top to bottom. For every interactive element, ask:

  1. What starts the interaction? Check whether it begins on page load, scroll, hover, click, focus, drag, swipe, or video playback.
  2. What moves or changes? Look for text, images, navigation, buttons, cards, panels, backgrounds, cursors, and overlays.
  3. How does it move? Note whether the element fades, slides, scales, rotates, clips, blurs, expands, or shifts position.
  4. What is the result? Confirm that the visitor can tell what opened, closed, selected, loaded, or became available.

This gives you a useful description even when you do not know the animation library or implementation.

The examples below include video-led pages such as Pangram AI Detector, Refero, Bland, and Fin Apex. Focus on the role of motion: is the video explaining the product, setting the mood, demonstrating a workflow, or filling visual space?

Captured pages

Check motion by page state

Review more than the initial page load. Test the states a visitor is likely to encounter:

  • Initial load: Does important content appear in a readable order, or does motion delay the main message?
  • Scroll: Do sections reveal, pin, transform, or change size? Check whether movement preserves the reading path.
  • Hover and focus: Do buttons, links, cards, and navigation items provide a clear visual response? Test keyboard focus as well as a pointer.
  • Open and close: For menus, modals, accordions, and drawers, check whether the movement matches the layout change.
  • Playback: For video or looping backgrounds, note whether playback starts automatically, whether controls are visible, and whether the visual remains understandable when paused.
  • Small screens: Repeat important checks at a narrow width. Motion that works on desktop may cover text, push controls down, or make a tap target hard to use on mobile.

For each state, save a short observation such as: "The hero video starts immediately, while the headline remains fixed and readable" or "The card expands on hover, but the action is less obvious without a pointer."

Separate useful motion from decoration

Motion is useful when it explains a relationship. A panel sliding from a button can show where the panel came from. A selected tab changing color and position can show which content is active. A product demonstration can reveal a workflow that would take several paragraphs to explain.

Motion is less useful when it competes with the task. Watch for repeated loops behind text, several elements entering at once, scrolling that feels detached from the content, or transitions that make a visitor wait before a simple action completes. Check whether an animation communicates state or merely adds movement.

A simple rating system helps compare pages:

  • Purpose: Does the motion explain, guide, confirm, or decorate?
  • Clarity: Can you identify what changed without replaying it?
  • Control: Can the visitor pause, dismiss, skip, or revisit it when needed?
  • Consistency: Do similar elements behave in similar ways?
  • Cost: Does it slow the page, obscure content, or make navigation harder?

Score each category from 1 to 5, then keep notes for the lowest scores.

Turn observations into a design brief

Finish with a short inventory rather than vague impressions. Include the section, trigger, animated property, approximate duration or rhythm, purpose, and any issue. For example: "Pricing cards: hover trigger; border and elevation change; quick transition; reinforces the selectable option; keyboard focus needs a matching treatment."

A captured website review can make this faster by inspecting page states, video, overlays, clipping, and interaction details together. The useful output is a set of observable patterns you can compare, test, and adapt to your own page.

Use this in your AI agent

> Check the motion and interactions on this captured website section. For each interaction, list the trigger, what changes, the movement type, the likely purpose, the resulting page state, and any clarity or usability concern. Separate purposeful motion from decoration, and finish with three patterns worth adapting and three things to test on mobile.

How should I review website motion on mobile and with a keyboard?

Review mobile and keyboard behavior as separate passes, because each exposes different problems.

On mobile, test the page at a narrow viewport and use touch rather than a pointer. Check whether tap targets remain easy to hit while an animation is running. Look for hover-only information that never appears on touch, sticky sections that cover content, videos that crop out the important action, and expanding panels that move the visitor farther than expected. Rotate the device or change the width slightly as well, since breakpoints can reveal abrupt jumps in layout or motion.

With a keyboard, use Tab, Shift-Tab, Enter, Space, and Escape. Track where focus goes when a menu, modal, accordion, or drawer opens. Focus should remain visible, and the visitor should understand which control is active. When an overlay closes, check whether focus returns to the control that opened it. A visual hover effect without a matching focus state is an important finding.

Record each issue with the state, trigger, visible result, and suggested fix. For example: "On narrow screens, the card reveals details only on hover; provide a tap or focus state instead."

Can you give me a simple template for documenting website interactions?

Use one row per interaction and keep the wording observable. This template works for a design review:

For a comparison across pages, add a score from 1 to 5 for purpose, clarity, control, consistency, and cost. Keep the score beside the evidence so it does not become a vague opinion.

If you are reviewing several captured references, group the notes by pattern: hero video, navigation, scroll reveal, card hover, modal, and media playback. Choose one strong example for each pattern and describe what you would preserve, simplify, or test. This produces a practical interaction brief instead of a list of screenshots.
