Why lightweight, focused plugins win

Full SEO suites are powerful but heavy — extra tables, dashboards, telemetry and features most sites never touch. For the majority of websites the essentials are simple: control your titles and descriptions, output valid structured data, keep thin pages out of the index, and help readers navigate. These plugins do exactly that in clean, readable PHP you can audit and modify.

One SEO plugin at a timeRunning two plugins that output the same tags causes duplicates. If you already use a full suite, pick the ConvertAtlas plugins that add something new.
  • FeatherweightNo bloat, no database sprawl, fast page loads.
  • Open sourceGPL-licensed PHP you can read and change.
  • PrivateNo external requests, no tracking, no account.
  • ModularUse one plugin or the whole suite — your call.
