★★★★★ — “This plugin saves me so much time, and it has really lifted my SERP rankings. Most of my keywords I now rank 1-3 position. I also noticed after about a week that my impressions have gone up at least 75%. I upgraded to the pro version which gave me even more options.” – playnstocks

★★★★★ — “Yoast on steroids! As an SEO marketer, I love using Yoast for my basic on-page SEO. But Yoast only allows you to enter basic Open Graph social settings.

Frequently Asked Questions

Advanced Documentation and Notes


December 8, 2019
The one thing I absolutely hate about this plugin, is not how it works, but it's licensing. I bought 3-4 parts of this plugin thinking that it would conform to the normal licensing schema of being able to move a license to another domain, with the ability to de-register it or change a domains name. This is not the case and it seems rather like a scam to me. One license should cover the plugin for any domain, because this current licensing schema is a joke. 1 site license should be for any site. Not an absolutely locked in domain name. The developer need not reply with his excuses. Because that is all they will be. Change your licensing scheme or stay silent.
November 20, 2019
I'd give it 5 stars if premium support hadn't been so crotchety about everything.

Release Schedule

New versions of the plugin are released approximately every week (more or less). New features are added, tested, and released incrementally, instead of grouping them together in a major version release. When minor bugs fixes and/or code improvements are applied, new versions are also released. This release schedule keeps the code stable and reliable, at the cost of more frequent updates.

See release early, release often (RERO) software development philosophy on Wikipedia for more information on the benefits of smaller / more frequent releases.

Version Numbering

Version components: {major}.{minor}.{bugfix}[-{stage}.{level}]

  • {major} = Major structural code changes / re-writes or incompatible API changes.
  • {minor} = New functionality was added or improved in a backwards-compatible manner.
  • {bugfix} = Backwards-compatible bug fixes or small improvements.
  • {stage}.{level} = Pre-production release: dev < a (alpha) < b (beta) < rc (release candidate).
