About tool
CachePlex brings together a curated set of practical web and marketing utilities in one place—so you can analyze, generate, and improve key on-page elements without setup friction.
Use the SEO Analyzer to run a full on-page audit from any publicly accessible URL. It checks 50+ SEO factors including title tags, headings, images (like missing alt text), structured data (schema/JSON-LD), and link structure, then returns a scored report plus an AI-generated summary with prioritized fixes.
Beyond audits, CachePlex includes tools like Meta Tag Generator (single or bulk via CSV), AI Humanizer (rewrite text into a warmer, more natural tone with a free tier), AI Text Detector (confidence scores and signal analysis), Readability Checker (Flesch scores without word limits), and generators for favicons, app icons, and QR codes—along with additional utilities for validation and code optimization.
Do I need an account to use the SEO Analyzer?
No. You can scan and get results without signing up or adding a credit card. Creating a free account is only useful if you want to save scan history.
