Frequently Asked Questions

Why are Open Graph and Twitter Card meta tags necessary?

When users share your links on platforms like X, Facebook, LinkedIn, Slack, or Discord, crawler bots scrape your page for Open Graph and Twitter Card tags to generate rich visual link preview cards with images and headlines, drastically increasing click-through rates.

What is the ideal length for SEO titles and descriptions?

Search engines typically display the first 50 to 60 characters of a page title and 150 to 160 characters of a meta description. Staying within these bounds prevents your snippet from being awkwardly truncated with ellipses.

What dimensions should my Open Graph image be?

The industry standard recommendation for social preview images (og:image) is 1200 x 630 pixels with an aspect ratio of 1.91:1. This ensures crisp rendering across high-DPI smartphone screens and desktop monitors.

Is my metadata or website URL sent to any server?

No. All tag generation, character auditing, and visual preview cards run 100% locally in your web browser. Your titles, descriptions, and credentials never leave your machine.
