Quick answer
WordPress database table errors — including overhead accumulation, collation mismatches, and table corruption — build up silently and slow your site before causing visible failures. Most site owners only discover them when something breaks. Checking your database health monthly, or using an automated monitoring plugin, catches these issues before they affect your visitors.
WP Canary monitors your database health automatically — free forever. The database health scanner runs daily and flags overhead, collation mismatches, and errors in your morning digest.
