Who Plerdy SEO Analyzer is for

  • Fits if you want a page's tags, readability and keyword use checked before you publish it

Who it is not for

  • Skip it if you want search volumes, rankings or backlinks, as none are on record
  • Not for you if you browse in Firefox, Safari or Edge, as it's listed for Chrome only
  • Watch out: the developer hasn't identified itself as a trader, so EU consumer rights don't apply

Keep it, or make your own?

Whether this is something you could build for yourself with an AI app builder, and what you would give up.

Keep it

Plerdy SEO Analyzer is free, so making your own would save you nothing.

And it is not the kind of software a weekend replaces.

What you could make

  • Schema markup: an app builder makes this well.

What you could not

  • A crawler that checks every page of a site.
  • A score built from what the top results for each keyword cover.
  • Speed tests run from real browsers on a schedule.
  • AI features, unless you pay a model provider for each request yourself.

What this rests on. Plerdy SEO Analyzer’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
