01

Fix WordPress H1 SEO issues

Fix WordPress SEO issues by keeping one clear H1, escaping template output, and compressing images before WordPress upload.

Beginner

02

Escape output at the template edge

Sanitize on input, escape on output, and keep theme templates strict about user content.

Beginner

03

Cache expensive queries

Use transients for custom queries that do not need to hit the database every request.

Intermediate

04

Avoid query_posts in templates

Use WP_Query or pre_get_posts so pagination and globals do not break unexpectedly.

Advanced

05

Load assets only where needed

Conditionally enqueue heavy scripts so every page does not pay for one feature.

Intermediate

06

Use nonces for actions

Protect form submissions and AJAX actions with WordPress nonces and capability checks.

Beginner

07

Register custom post types early

Register CPTs on init with stable slugs so rewrite rules, archives, and permissions stay predictable.

Intermediate

08

Avoid hardcoded site URLs

Use WordPress URL helpers so staging, production, and migrations do not break links.

Beginner

09

Use template parts for repeated UI

Move repeated cards, headers, and loops into template parts so changes happen in one place.

Beginner

10

Audit autoloaded options

Large autoloaded options slow every request because WordPress loads them globally.

Advanced

11

Use scheduled events for background work

Move slow cleanup, sync, and email jobs out of the page request with scheduled events.

Intermediate

12

Limit REST API fields

Request only the fields your frontend needs so headless pages do not move oversized JSON.

Intermediate

13

Sanitize ACF fields by context

Treat ACF values as content that still needs escaping based on where it appears.

Intermediate

14

Use image sizes deliberately

Register and use the right image sizes so templates do not load full-resolution uploads.

Beginner

15

Keep plugin logic out of themes

Put business logic in plugins so redesigning the theme does not remove core features.

Advanced

16

Flush rewrites only on activation

Do not flush rewrite rules on every request; do it when plugins or route structures change.

Intermediate

A repeatable workflow

From useful idea to better production code.

Every field note follows the same short path, so you can understand it, use it, and verify the result without reading a long tutorial.
