§ what this tool checks

A missing or misconfigured meta description means Google writes one for you — and it rarely says what you want.

§ faq

Questions, answered.

What are meta tags and why do they matter for SEO?

Meta tags are HTML elements in the <head> of your page that provide metadata to search engines and browsers. The title tag and meta description directly influence how your page appears in search results, affecting click-through rates. The robots meta tag controls whether search engines index your page at all — a single misconfigured robots tag can make your entire site invisible to Google.

How do I fix a missing meta description?

Add a <meta name="description" content="Your description here"> tag to the <head> section of your HTML. Keep it between 150-160 characters and make it a compelling summary of the page content. Each page should have a unique meta description that includes relevant keywords naturally.

What is the ideal title tag length?

Google typically displays the first 50-60 characters of a title tag. Titles longer than this get truncated with an ellipsis in search results. Put your most important keywords near the beginning of the title, and keep it descriptive and unique for each page.

What does a canonical URL do?

A canonical URL (rel="canonical") tells search engines which version of a page is the "primary" one when duplicate or similar content exists across multiple URLs. This prevents duplicate content issues and consolidates link equity to your preferred URL. Without it, search engines may split ranking signals across multiple versions of the same page.
