ONE JOB. DONE PROPERLY.

The problem

## Performance problems hide behind technical noise.

A slow WordPress site can involve database bloat, background jobs, PHP pressure, caching, memory, plugins, or the host itself. Site Signal gathers the evidence into one decision-focused dashboard so owners and developers know where to investigate first.

What it does

## Focused. Not bloated.

Six practical capabilities, organized around the one job this plugin is meant to do.

01
### Expert triage

Green, yellow, red, and unavailable ratings summarize the first checks a WordPress professional would make.

02
### Database evidence

Inspect large tables, autoload size, transients, response time, running threads, slow-query rate, and lock waits.

03
### Background work

See WP-Cron backlog, duplicate pressure, frequent tasks, and Action Scheduler failures or overdue jobs.

04
### Server + PHP

Review memory headroom, OPcache, object cache, runtime details, disk availability, and host-aware limitations.

05
### Real response tests

Compare ordinary and cache-bypass homepage requests to separate front-end cache behavior from backend work.

06
### Dashboard widget

Keep PHP memory, database response, top alerts, and red-rated tables visible at a glance.

How it works

## A controlled path from evidence to action.

- 01 Read the available WordPress, PHP, database, and server evidence.

- 02 Classify measurable conditions and explain them in plain language.

- 03 Surface likely problems before possible slowdowns and neutral information.

- 04 Recommend where to investigate next without performing automatic repairs.

The boundary

## Read-only by design.

Site Signal does not delete records, optimize tables, change configuration, or deactivate plugins. When hosting data is unavailable or too broad to prove a site-level conclusion, the limitation is shown plainly.
