Meta tags are the backbone of on-page SEO. They tell search engines what your page is about, how to display it in search results, and whether to index it at all. For Astro sites deployed on Cloudflare Workers, getting meta tags right is both easier and more important than you might think.

Why Meta Tags Matter for Astro Sites

Astro builds static HTML by default, which means search engines can read your content easily. But without proper meta tags, Google has to guess what your page is about. That guess often leads to wrong titles, bad descriptions, and lower click-through rates.

Meta tags give you control over how your site appears in search results. The three most important ones are:

Title tag — The clickable headline in search results. Keep it under 60 characters and include your primary keyword near the front.

Meta description — The summary beneath the title. Aim for 150-160 characters that make people want to click.

OG and Twitter cards — Control how your page looks when shared on social media. Open Graph (og:title, og:description, og:image) and Twitter Card meta tags are essential for social sharing.

How EmDash Auto Blog/SEO Handles Meta Tags

The Auto Blog/SEO plugin for EmDash provides a dedicated SEO management panel where you can set meta tags for every page and post. The Free tier includes:

Custom meta titles and descriptions per page

Auto-generated OG and Twitter Card tags from your content

An SEO score that rates your meta tag quality on a 100-point scale

Real-time preview of how your page looks in search results

Best of all, it handles the boilerplate so you don't have to manually edit <head> sections for every page. Just fill in the fields and the plugin injects the right tags at build time.

Getting Started

If you're running EmDash on your Astro site, install the Auto Blog/SEO plugin from the admin dashboard. Navigate to any page or post, open the SEO panel, and start optimizing. The SEO score gives you immediate feedback on whether your meta tags are working hard enough.
