Frequently Asked Questions
QWhy is my description showing as missing?
Many pages dynamically insert meta tags via JavaScript. View Source won't show JS-rendered tags — you'd need to inspect the rendered DOM instead.
QDoes this tool fetch my page?
No — you paste the HTML. Nothing is fetched or transmitted. All analysis runs in your browser.
QWhat counts as a "good" meta description?
Between 120–155 characters, contains relevant keywords, is descriptive, and unique to the page. Avoid duplicate descriptions across your site.
About This Tool
Meta tag analysis is a core part of technical SEO auditing. This tool performs client-side HTML parsing using the browser's native DOMParser API — no server requests needed.
