Plerdy SEO Analyzer report card
Very good · out of 4.0 · graded Oct 23, 2026
Best for a scored on-page audit of one page
Plerdy SEO Analyzer checks the page you're on for tags, headings, canonical and hreflang, links, images, Open Graph and schema, scores it from 0 to 100 and adds AI tips, readability figures and load timings, for free. It looks at one page at a time, daily site audits and Search Console alerts sit in Plerdy's separate SEO Checker, and it's Chrome only.
Who Plerdy SEO Analyzer is for
- Fits if you want a page's tags, readability and keyword use checked before you publish it
- Works for developers looking for slow scripts, styles and images on a single page
Who Plerdy SEO Analyzer is not for
- Too light for whole-site audits, as daily site checks and Search Console alerts are Plerdy's separate SEO Checker
- 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 Plerdy SEO Analyzer, or make your own?
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.
