TITLE TAG & META DESCRIPTION CHECKER

Title tags should be 50–60 characters. Meta descriptions 150–160 characters. Too short and you're wasting valuable real estate. Too long and Google truncates them in the SERP — sometimes replacing them entirely.

Our extension shows character counts in real time with color-coded warnings: green (optimal), yellow (borderline), red (too short or too long). You also see a live preview of how your title and description will look in Google search results.

Word count and character count tools are built in — useful for editors checking content length, writers hitting target word counts, and developers validating dynamic title tag templates.

HEADING STRUCTURE ANALYZER

Proper heading hierarchy (H1 → H2 → H3) helps Google understand your content structure and helps users navigate your page. A broken heading structure is one of the most common and easiest-to-fix SEO issues.

The extension extracts every heading tag on the page, shows it as an outline, and flags problems: multiple H1s, skipped heading levels (H1 → H3 with no H2), headings with no text, headings inside iframes.

It also shows keyword density in headings — useful for checking whether your target keyword appears in the H1 and supporting H2s.

SCHEMA MARKUP VALIDATOR

The extension detects all structured data on the page — JSON-LD, Microdata, RDFa — and shows you the schema types present, any validation errors, and which rich results the page might be eligible for.

No more copy-pasting into Google's Rich Results Test. See schema status directly on the page, in context, while you're reviewing or editing content.

CORE WEB VITALS IN YOUR BROWSER

Lab data from Lighthouse, field data from the Chrome UX Report, and real-time metrics as you browse. LCP, CLS, INP — all visible without opening DevTools or running a separate PageSpeed Insights test.

Check your pages AND your competitors' pages. CWV is a ranking signal — if your competitor is passing and you're not, that's a gap you can close.

DOMAIN AUTHORITY CHECKER

Domain authority and page authority metrics give you a quick read on how much trust a website has built with search engines. The extension pulls DA/PA data for any page you visit — useful for competitor research, link prospecting, and client reporting.

Check a site before outreaching for a guest post. See how strong a competitor's backlink profile is. Evaluate whether a citation source is worth pursuing.
