What meta tag analysis is for
It lists title, description, robots, canonical, Open Graph, Twitter Card and verification tags from the head. The SEO analyzer scores them. This tool prints the raw list. If a theme and a plugin both print a description, you see both rows.
Google does not use the keywords tag for ranking. A filled keywords tag is not an advantage. Title, description, canonical and robots are the rows that matter. Open Graph decides the title and image when the URL is shared.
| Tag | Job | Healthy shape |
|---|---|---|
| title | The blue result title | 50–60 characters, unique to the page |
| description | The snippet | Near 160 characters, not a copy of the title |
| robots | Index and follow | May be absent if you are not sending noindex |
| canonical | The preferred URL | The page’s own absolute URL |
| og:title / og:image | Social share | Image must be an absolute URL |
| twitter:card | Card type on X | summary or summary_large_image |
