To extract interaction patterns from a website URL, map what the visitor can do, what changes on screen, and what each interaction helps them decide. Start with navigation and the first action, then inspect scrolling, menus, cards, forms, media, and responsive behavior as separate patterns.

Build an interaction inventory

Create a table with four columns: location, trigger, visible change, purpose. For every meaningful interaction, record where it appears, what starts it, what the visitor sees, and why it exists.

Useful rows include:

Header links, menu opening, sticky navigation, and section jumps.
Hero buttons, signup prompts, demo requests, or product tours.
Tabs, accordions, carousels, filters, and expandable feature cards.
Hover states, cursor changes, tooltips, and highlighted comparisons.
Scroll-triggered reveals, pinned sections, progress indicators, and transitions.
Video playback, muted autoplay, captions, scrubbing, and poster images.
Forms, validation messages, password visibility, and confirmation states.
Pricing toggles, plan comparisons, calculators, and saved selections.

Do not describe an interaction only as "nice animation." Record the trigger and the result. "On scroll, the product screenshot moves while the related explanation stays visible" is useful. It gives a designer something that can be evaluated and rebuilt.

The examples below include video-led and illustration-led marketing pages such as Pangram AI Detector, Refero, Bland, and Fin Apex. Compare them for how media supports a message, not simply for whether a page contains video.

Captured pages

Inspect the page in passes

Use four passes so the inventory does not become a random list.

Pass one: navigation. Open the page at the starting viewport. Note what is immediately available, whether the header changes after scrolling, and whether the main action stays easy to reach.

Pass two: content reveal. Scroll slowly and record anything that changes after a threshold: text appearing, images replacing one another, cards pinning, counters updating, or sections changing background. Capture the order and approximate duration rather than guessing at implementation details.

Pass three: direct interaction. Click every visible control once. Record whether it opens a panel, changes content in place, moves to another section, starts media, or begins a form. Include the return path. An interaction is incomplete if the visitor cannot understand how to close, undo, or continue.

Pass four: responsive behavior. Repeat the review at a narrow viewport. Check whether menus collapse, columns stack, media crops differently, controls remain reachable, and text still explains the action. A desktop pattern is not automatically a good mobile pattern.

Separate patterns from decoration

A useful interaction earns its space by improving understanding, reducing effort, or helping comparison. A decorative effect may still support tone, but it should not delay the main message or hide essential content.

For each pattern, assign one role:

Orient: helps visitors understand where they are.
Explain: reveals how a product or workflow works.
Compare: lets visitors evaluate choices or outcomes.
Prove: demonstrates a result or real product state.
Convert: makes the next step easier.
Delight: adds personality without carrying essential meaning.

Prioritize orient, explain, compare, prove, and convert. Treat delight as optional, especially when it adds loading time, competes with reading, or becomes difficult to use on a smaller screen.

Turn observations into a reusable pattern sheet

For each interaction, write a compact specification:

Pattern name: "sticky section navigation" or "scroll-linked product tour."
Visitor goal: what the person is trying to understand or do.
Trigger: click, hover, scroll, time, input, or viewport change.
State change: what appears, moves, expands, pauses, or becomes selected.
Content requirement: text, image, video, labels, or fallback.
Exit or recovery: close, back, reset, pause, or error behavior.
Responsive rule: what changes on narrow screens.
Keep or adapt: whether the pattern fits your own message and audience.

This keeps extraction separate from copying. You are saving the behavior and the reason for it, then adapting the pattern to your own content, assets, accessibility needs, and brand.

> Inspect this website URL and extract its interaction patterns. Create an inventory with location, trigger, visible state change, visitor purpose, exit or recovery behavior, and responsive behavior. Cover navigation, scrolling, menus, cards, forms, media, hover states, and conversion actions. Separate useful patterns from decoration, note anything that needs verification, and finish with a prioritized pattern sheet I can adapt to my own website without copying the original content or branding.

What interaction patterns should I look for first on a marketing website?

Start with patterns that affect the visitor's path through the page. Check the header and hero first: does navigation stay available, does the main action remain clear, and does any menu or button reveal useful context?

Next, inspect how the page explains the product. Look for tabs, accordions, scroll-linked demonstrations, pinned screenshots, before-and-after views, product tours, and video controls. Record what changes and whether the visitor can control or revisit it.

Then review conversion patterns: pricing switches, plan comparisons, forms, validation, confirmation messages, booking steps, and return paths. These often matter more than visual effects because they change the amount of effort required.

On mobile, check menu access, stacked sections, cropped media, touch target size, and whether interactions that depended on hover still make sense. The best first inventory is usually a short list of repeatable behaviors with clear purposes, not every transition on the page.

How do I turn extracted website interactions into a design system?

Group observations into reusable behavior families instead of keeping a page-by-page scrapbook. Common families include navigation, disclosure, selection, comparison, media playback, scrolling, forms, feedback, and conversion.

For each family, define the shared parts: trigger, default state, active state, loading state, error state, close or reset behavior, content limits, and narrow-screen rule. Then list the visual details separately, such as type scale, color roles, spacing, borders, and motion timing. This prevents a pattern from becoming tied to one brand's styling.

Choose one representative example for each family and write when to use it and when not to use it. For example, a pinned scroll demonstration may suit a short product story but become tiring when repeated across several sections. A tab pattern may help comparison, but important content should not disappear without a clear label.

Finish by testing the system with a new page. If the rules help you choose and build a behavior without returning to the source website, the extraction is useful.
