Five Causes of Slow WordPress Sites
The article explains common reasons why WordPress sites remain slow despite optimization efforts and gives practical fixes. It identifies five main causes: too many plugins, heavy themes with unused code, missing or misconfigured caching, unoptimized images, and hosting not built for WordPress. Recommended actions include removing unused plugins, choosing a lightweight theme, enabling server-side caching (often provided by specialist WordPress hosts), serving images in modern formats (e.g., WebP) with lazy loading, and moving to managed WordPress hosting optimized for performance and uptime. The piece cites Raidboxes as an example of a managed WordPress host and notes a promotional 50% discount on first hosting contracts for moves completed by 2026-04-28.
Practical guidance on WordPress performance and hosting relevant to website publishers and martech practitioners; useful but not industry-shifting.

Three unsolved gaps in WordPress maintenance tools
A side-by-side survey of four long-running WordPress maintenance tools — ManageWP, MainWP, WP Umbrella and InfiniteWP — found three structural gaps none of them solve: (1) per-plugin updates with an HTTP check between each update, (2) pinpoint rollback that reverts only the plugin that broke a site, and (3) managing sites without installing a Worker/Child plugin. The author explains these gaps arise from WordPress API design (favoring batch updates), state-management and storage complexity (making per-plugin backups impractical), and connectivity/compatibility trade-offs that make a gateway plugin the pragmatic industry choice. The piece notes WP-CLI + SSH as an alternative that enables step-by-step updates and targeted rollback but is limited to hosts where SSH/WP-CLI are available. Published 2026-06-13.

Optimizing WordPress Databases with Essential WP-CLI Commands
This technical guide highlights the utility of WP-CLI commands `wp db check` and `wp db optimize` for maintaining WordPress database health. Over time, WordPress databases accumulate bloat such as spam comments, expired transients, and fragmented tables. The `wp db check` command verifies table health and identifies database corruption, while `wp db optimize` defragments tables and reclaims unused disk space, particularly for older MyISAM or standard InnoDB engines. The guide advises running these commands after bulk deletions, before major updates, or as part of routine maintenance. Additionally, `wp db repair` is recommended as a recovery option for corrupted tables, provided a fresh backup is taken beforehand.
