# 07. SEO, Accessibility, and Performance

## Purpose

Define the non-functional expectations that should shape the build from the start.

## Scope

- SEO structure for property and content pages.
- Metadata and structured content needs.
- Accessibility requirements.
- Responsive behavior.
- Performance targets.
- Image handling and gallery behavior.

## Proposed Non-Functional Standards

### SEO

- Every public page should have a clear title, meta description, and canonical intent.
- Property pages should be SEO-friendly and indexable when published.
- Structured content should support search visibility for properties, location pages, and static pages.

### Accessibility

- Forms, navigation, filters, and booking flows must be keyboard usable.
- Labels, focus states, and error messages must be explicit.
- Color contrast and readable spacing should be part of the base design.

### Responsive Behavior

- The site must work on mobile, tablet, and desktop.
- Listing cards, booking panels, and galleries must reflow cleanly on smaller screens.
- Admin screens should remain usable on typical laptop widths.

### Performance

- Image delivery should be optimized for property galleries and listing cards.
- Search and filter interactions should remain responsive.
- The public pages should avoid unnecessary blocking work on initial load.

### Image Handling

- Property images should support primary and gallery presentation.
- Alt text should be mandatory where images are public-facing.
- Image ordering should be controllable from the admin.

## What Needs to Be Done

- Define the SEO fields required for each page type.
- Define the accessibility baseline for forms, navigation, and booking flows.
- Define mobile and tablet behavior expectations.
- Define performance expectations for images, page load, and search filtering.
- Define any page types that should be noindex or hidden from search engines.
- Define target performance expectations if the team wants measurable thresholds.

## Acceptance Criteria

- SEO requirements are tied to page types, not treated as an afterthought.
- The UI requirements are responsive by design.
- Key flows are usable with keyboard and assistive tech.
- Performance expectations are written in measurable terms where possible.
- Image handling and alt text rules are explicit enough for implementation.

## Dependencies

- Public website planning.
- Content architecture and data model.

## Notes

- This document should keep the eventual implementation honest about quality, not just features.
