Missing meta description
The meta description is your ad copy in search results. Without one, Google stitches together a snippet from the page.
What it is
This check flags pages with no meta description tag.
Why it matters for SEO
Though not a direct ranking factor, the description heavily influences click-through. A weak auto-snippet costs clicks.
Example
<!-- no meta name='description' in head -->
How to fix
- Write a unique description of about 140-160 characters per page.
- Summarise the value and add a natural call to action.
- Reflect the primary keyword without stuffing.
- Re-crawl to confirm descriptions are present.
